Inflammation of the extraocular muscle of the eye. It is characterized by swelling which can lead to ischemia, fibrosis, or ORBITAL PSEUDOTUMOR.
A nonspecific tumor-like inflammatory lesion in the ORBIT of the eye. It is usually composed of mature LYMPHOCYTES; PLASMA CELLS; MACROPHAGES; LEUKOCYTES with varying degrees of FIBROSIS. Orbital pseudotumors are often associated with inflammation of the extraocular muscles (ORBITAL MYOSITIS) or inflammation of the lacrimal glands (DACRYOADENITIS).
Inflammation of a muscle or muscle tissue.
Virus infection of the Gasserian ganglion and its nerve branches characterized by pain and vesicular eruptions with much swelling. Ocular involvement is usually heralded by a vesicle on the tip of the nose. This area is innervated by the nasociliary nerve.
Refers to any inflammation of the sclera including episcleritis, a benign condition affecting only the episclera, which is generally short-lived and easily treated. Classic scleritis, on the other hand, affects deeper tissue and is characterized by higher rates of visual acuity loss and even mortality, particularly in necrotizing form. Its characteristic symptom is severe and general head pain. Scleritis has also been associated with systemic collagen disease. Etiology is unknown but is thought to involve a local immune response. Treatment is difficult and includes administration of anti-inflammatory and immunosuppressive agents such as corticosteroids. Inflammation of the sclera may also be secondary to inflammation of adjacent tissues, such as the conjunctiva.
Progressive myopathies characterized by the presence of inclusion bodies on muscle biopsy. Sporadic and hereditary forms have been described. The sporadic form is an acquired, adult-onset inflammatory vacuolar myopathy affecting proximal and distal muscles. Familial forms usually begin in childhood and lack inflammatory changes. Both forms feature intracytoplasmic and intranuclear inclusions in muscle tissue. (Adams et al., Principles of Neurology, 6th ed, pp1409-10)
Diseases of the bony orbit and contents except the eyeball.
Neoplasms of the bony orbit and contents except the eyeball.
Bony cavity that holds the eyeball and its associated tissues and appendages.
Fractures of the bones in the orbit, which include parts of the frontal, ethmoidal, lacrimal, and sphenoid bones and the maxilla and zygoma.
Diseases characterized by inflammation involving multiple muscles. This may occur as an acute or chronic condition associated with medication toxicity (DRUG TOXICITY); CONNECTIVE TISSUE DISEASES; infections; malignant NEOPLASMS; and other disorders. The term polymyositis is frequently used to refer to a specific clinical entity characterized by subacute or slowly progressing symmetrical weakness primarily affecting the proximal limb and trunk muscles. The illness may occur at any age, but is most frequent in the fourth to sixth decade of life. Weakness of pharyngeal and laryngeal muscles, interstitial lung disease, and inflammation of the myocardium may also occur. Muscle biopsy reveals widespread destruction of segments of muscle fibers and an inflammatory cellular response. (Adams et al., Principles of Neurology, 6th ed, pp1404-9)
A subacute or chronic inflammatory disease of muscle and skin, marked by proximal muscle weakness and a characteristic skin rash. The illness occurs with approximately equal frequency in children and adults. The skin lesions usually take the form of a purplish rash (or less often an exfoliative dermatitis) involving the nose, cheeks, forehead, upper trunk, and arms. The disease is associated with a complement mediated intramuscular microangiopathy, leading to loss of capillaries, muscle ischemia, muscle-fiber necrosis, and perifascicular atrophy. The childhood form of this disease tends to evolve into a systemic vasculitis. Dermatomyositis may occur in association with malignant neoplasms. (From Adams et al., Principles of Neurology, 6th ed, pp1405-6)
Muscles arising in the zygomatic arch that close the jaw. Their nerve supply is masseteric from the mandibular division of the trigeminal nerve. (From Stedman, 25th ed)
Two of the masticatory muscles: the internal, or medial, pterygoid muscle and external, or lateral, pterygoid muscle. Action of the former is closing the jaws and that of the latter is opening the jaws, protruding the mandible, and moving the mandible from side to side.
Diseases of the domestic dog (Canis familiaris). This term does not include diseases of wild dogs, WOLVES; FOXES; and other Canidae for which the heading CARNIVORA is used.
A masticatory muscle whose action is closing the jaws; its posterior portion retracts the mandible.
A masticatory muscle whose action is closing the jaws.
Longitudinal cavities in the spinal cord, most often in the cervical region, which may extend for multiple spinal levels. The cavities are lined by dense, gliogenous tissue and may be associated with SPINAL CORD NEOPLASMS; spinal cord traumatic injuries; and vascular malformations. Syringomyelia is marked clinically by pain and PARESTHESIA, muscular atrophy of the hands, and analgesia with thermoanesthesia of the hands and arms, but with the tactile sense preserved (sensory dissociation). Lower extremity spasticity and incontinence may also develop. (From Adams et al., Principles of Neurology, 6th ed, p1269)

Idiopathic orbital myositis associated with Graves' disease. (3/4)

A 52-year-old man was referred to our clinic. One week before his visit, he had complained of left eye pain and double vision. His clinical features were exacerbated. Despite the acute onset, which is atypical of thyroid eye disease (TED), TED was suspected due to the patient's history of Graves' disease (GD). After conducting clinical examinations and orbital magnetic resonance imaging, the patient was diagnosed with idiopathic orbital myositis (IOM), and intravenous glucocorticoid therapy was administered. After treatment, the patient's clinical manifestations dramatically improved. This is a rare case in that the history of GD made it difficult to differentiate IOM from TED.  (+info)

Orbital myositis is a medical condition characterized by inflammation of the extraocular muscles, which are the muscles responsible for eye movement. These muscles are located within the orbit, the bony cavity that contains and protects the eye. Orbital myositis can cause symptoms such as painful eye movements, double vision, redness, swelling, and decreased visual acuity.

The condition is often associated with other systemic inflammatory or autoimmune disorders, such as rheumatoid arthritis, granulomatosis with polyangiitis (GPA), and sarcoidosis. However, it can also occur as an isolated phenomenon, known as idiopathic orbital myositis.

Diagnosis of orbital myositis typically involves a combination of clinical examination, imaging studies such as MRI or CT scans, and blood tests to evaluate for underlying systemic conditions. Treatment usually includes corticosteroids to reduce inflammation and alleviate symptoms, as well as addressing any underlying systemic disorders if present.

Orbital pseudotumor, also known as orbital inflammatory syndrome or idiopathic orbital inflammation, is a non-specific term used to describe a group of conditions characterized by inflammation in the orbit (the bony cavity surrounding the eye) without any identifiable cause. It is not a true tumor, but rather an inflammatory reaction that can mimic the symptoms and signs of a tumor.

The condition can affect people of any age, although it is more common in middle-aged adults. The exact cause of orbital pseudotumor is unknown, but it is believed to be related to an abnormal immune response or inflammation triggered by various factors such as infections, trauma, or autoimmune disorders.

Symptoms of orbital pseudotumor may include eye pain, redness, swelling, protrusion of the eyeball (proptosis), double vision, and decreased vision. Diagnostic tests such as imaging studies (CT or MRI scans) and biopsy may be used to rule out other causes of orbital inflammation. Treatment typically involves corticosteroids to reduce inflammation, although other immunosuppressive medications may be necessary in severe cases. In some cases, the condition may resolve on its own without treatment.

Myositis is a medical term that refers to inflammation of the muscle tissue. This condition can cause various symptoms, including muscle weakness, pain, swelling, and stiffness. There are several types of myositis, such as polymyositis, dermatomyositis, and inclusion body myositis, which have different causes and characteristics.

Polymyositis is a type of myositis that affects multiple muscle groups, particularly those close to the trunk of the body. Dermatomyositis is characterized by muscle inflammation as well as a skin rash. Inclusion body myositis is a less common form of myositis that typically affects older adults and can cause both muscle weakness and wasting.

The causes of myositis vary depending on the type, but they can include autoimmune disorders, infections, medications, and other medical conditions. Treatment for myositis may involve medication to reduce inflammation, physical therapy to maintain muscle strength and flexibility, and lifestyle changes to manage symptoms and prevent complications.

Herpes Zoster Ophthalmicus (HZO) is a type of herpes zoster (shingles) infection that affects the ophthalmic division (V1) of the trigeminal nerve. It is caused by the varicella-zoster virus, which also causes chickenpox. After a person recovers from chickenpox, the virus remains inactive in the body and can reactivate later as shingles, often many years after the initial infection.

When the virus reactivates and affects the ophthalmic division of the trigeminal nerve, it can cause a painful rash on the forehead, nose, and around one eye. The rash may be accompanied by other symptoms such as headache, fever, and fatigue. In some cases, HZO can also affect the eye itself, causing inflammation, corneal ulcers, and vision loss if left untreated.

It is important to seek medical attention promptly if you suspect you have HZO, as early treatment with antiviral medications can help reduce the severity of symptoms and prevent complications.

Scleritis is a serious, painful inflammatory condition that affects the sclera, which is the white, tough outer coating of the eye. It can lead to severe pain, light sensitivity, and potential loss of vision if not promptly treated. Scleritis may occur in isolation or be associated with various systemic diseases such as rheumatoid arthritis, lupus, or granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis). Immediate medical attention is necessary for proper diagnosis and management.

Inclusion body myositis (IBM) is a rare inflammatory muscle disease characterized by progressive weakness and wasting (atrophy) of skeletal muscles. The term "inclusion body" refers to the presence of abnormal protein accumulations within muscle fibers, which are observed under a microscope during muscle biopsy. These inclusions are primarily composed of aggregated forms of amyloid-β and tau proteins, similar to those found in neurodegenerative disorders like Alzheimer's disease.

IBM typically affects individuals over 50 years old, and it is more common in men than women. The disease usually starts with weakness in the wrist and finger flexors, making it difficult to perform tasks such as gripping, buttoning shirts, or lifting objects. Over time, the weakness spreads to other muscle groups, including the thigh muscles (quadriceps), resulting in difficulty climbing stairs or rising from a seated position.

The exact cause of inclusion body myositis remains unclear; however, both immune-mediated and degenerative mechanisms are believed to contribute to its pathogenesis. Currently, there is no cure for IBM, and treatment options are primarily aimed at managing symptoms and improving quality of life. Immunosuppressive medications may be used to target the inflammatory component of the disease; however, their efficacy varies among patients. Physical therapy and exercise programs can help maintain muscle strength and function as much as possible.

Orbital diseases refer to a group of medical conditions that affect the orbit, which is the bony cavity in the skull that contains the eye, muscles, nerves, fat, and blood vessels. These diseases can cause various symptoms such as eyelid swelling, protrusion or displacement of the eyeball, double vision, pain, and limited extraocular muscle movement.

Orbital diseases can be broadly classified into inflammatory, infectious, neoplastic (benign or malignant), vascular, traumatic, and congenital categories. Some examples of orbital diseases include:

* Orbital cellulitis: a bacterial or fungal infection that causes swelling and inflammation in the orbit
* Graves' disease: an autoimmune disorder that affects the thyroid gland and can cause protrusion of the eyeballs (exophthalmos)
* Orbital tumors: benign or malignant growths that develop in the orbit, such as optic nerve gliomas, lacrimal gland tumors, and lymphomas
* Carotid-cavernous fistulas: abnormal connections between the carotid artery and cavernous sinus, leading to pulsatile proptosis and other symptoms
* Orbital fractures: breaks in the bones surrounding the orbit, often caused by trauma
* Congenital anomalies: structural abnormalities present at birth, such as craniofacial syndromes or dermoid cysts.

Proper diagnosis and management of orbital diseases require a multidisciplinary approach involving ophthalmologists, neurologists, radiologists, and other specialists.

Orbital neoplasms refer to abnormal growths or tumors that develop in the orbit, which is the bony cavity that contains the eyeball, muscles, nerves, fat, and blood vessels. These neoplasms can be benign (non-cancerous) or malignant (cancerous), and they can arise from various types of cells within the orbit.

Orbital neoplasms can cause a variety of symptoms depending on their size, location, and rate of growth. Common symptoms include protrusion or displacement of the eyeball, double vision, limited eye movement, pain, swelling, and numbness in the face. In some cases, orbital neoplasms may not cause any noticeable symptoms, especially if they are small and slow-growing.

There are many different types of orbital neoplasms, including:

1. Optic nerve glioma: a rare tumor that arises from the optic nerve's supportive tissue.
2. Orbital meningioma: a tumor that originates from the membranes covering the brain and extends into the orbit.
3. Lacrimal gland tumors: benign or malignant growths that develop in the lacrimal gland, which produces tears.
4. Orbital lymphangioma: a non-cancerous tumor that arises from the lymphatic vessels in the orbit.
5. Rhabdomyosarcoma: a malignant tumor that develops from the skeletal muscle cells in the orbit.
6. Metastatic tumors: cancerous growths that spread to the orbit from other parts of the body, such as the breast, lung, or prostate.

The diagnosis and treatment of orbital neoplasms depend on several factors, including the type, size, location, and extent of the tumor. Imaging tests, such as CT scans and MRI, are often used to visualize the tumor and determine its extent. A biopsy may also be performed to confirm the diagnosis and determine the tumor's type and grade. Treatment options include surgery, radiation therapy, chemotherapy, or a combination of these approaches.

In medical terms, the orbit refers to the bony cavity or socket in the skull that contains and protects the eye (eyeball) and its associated structures, including muscles, nerves, blood vessels, fat, and the lacrimal gland. The orbit is made up of several bones: the frontal bone, sphenoid bone, zygomatic bone, maxilla bone, and palatine bone. These bones form a pyramid-like shape that provides protection for the eye while also allowing for a range of movements.

Orbital fractures refer to breaks in the bones that make up the eye socket, also known as the orbit. These bones include the maxilla, zygoma, frontal bone, and palatine bone. Orbital fractures can occur due to trauma, such as a blunt force injury or a penetrating wound.

There are several types of orbital fractures, including:

1. Blowout fracture: This occurs when the thin bone of the orbital floor is broken, often due to a direct blow to the eye. The force of the impact can cause the eyeball to move backward, breaking the bone and sometimes trapping the muscle that moves the eye (the inferior rectus).
2. Blow-in fracture: This type of fracture involves the breakage of the orbital roof, which is the bone that forms the upper boundary of the orbit. It typically occurs due to high-impact trauma, such as a car accident or a fall from a significant height.
3. Direct fracture: A direct fracture happens when there is a break in one or more of the bones that form the walls of the orbit. This type of fracture can result from a variety of traumas, including motor vehicle accidents, sports injuries, and assaults.
4. Indirect fracture: An indirect fracture occurs when the force of an injury is transmitted to the orbit through tissues surrounding it, causing the bone to break. The most common type of indirect orbital fracture is a blowout fracture.

Orbital fractures can cause various symptoms, including pain, swelling, bruising, and double vision. In some cases, the fracture may also lead to enophthalmos (sinking of the eye into the orbit) or telecanthus (increased distance between the inner corners of the eyes). Imaging tests, such as CT scans, are often used to diagnose orbital fractures and determine the best course of treatment. Treatment may include observation, pain management, and in some cases, surgery to repair the fracture and restore normal function.

Polymyositis is defined as a rare inflammatory disorder that causes muscle weakness and inflammation (swelling) of the muscles. It primarily affects the skeletal muscles, which are the muscles responsible for voluntary movements such as walking, talking, and swallowing. The onset of polymyositis can occur at any age but is most commonly seen in adults between 31 to 60 years old, with women being slightly more affected than men.

The exact cause of polymyositis remains unknown; however, it is believed to be an autoimmune disorder, where the body's immune system mistakenly attacks its own muscle tissue. Certain factors such as genetics, viral infections, and exposure to certain drugs may contribute to the development of this condition.

Polymyositis can cause various symptoms, including:
- Progressive muscle weakness and wasting, particularly affecting the proximal muscles (those closest to the trunk of the body) such as the hips, thighs, shoulders, and upper arms.
- Difficulty climbing stairs, lifting objects, or rising from a seated position.
- Fatigue and stiffness, especially after periods of inactivity.
- Joint pain and swelling.
- Difficulty swallowing or speaking.
- Shortness of breath due to weakened respiratory muscles.

Diagnosis of polymyositis typically involves a combination of medical history, physical examination, laboratory tests, electromyography (EMG), and muscle biopsy. Treatment usually includes medications such as corticosteroids and immunosuppressants to reduce inflammation and control the immune response. Physical therapy may also be recommended to help maintain muscle strength and flexibility.

If left untreated, polymyositis can lead to significant disability and complications, including respiratory failure, malnutrition, and cardiovascular disease. Early diagnosis and treatment are crucial for improving outcomes and preventing long-term complications.

Dermatomyositis is a medical condition characterized by inflammation and weakness in the muscles and skin. It is a type of inflammatory myopathy, which means that it causes muscle inflammation and damage. Dermatomyositis is often associated with a distinctive rash that affects the skin around the eyes, nose, mouth, fingers, and toes.

The symptoms of dermatomyositis can include:

* Progressive muscle weakness, particularly in the hips, thighs, shoulders, and neck
* Fatigue
* Difficulty swallowing or speaking
* Skin rash, which may be pink or purple and is often accompanied by itching
* Muscle pain and tenderness
* Joint pain and swelling
* Raynaud's phenomenon, a condition that affects blood flow to the fingers and toes

The exact cause of dermatomyositis is not known, but it is believed to be related to an autoimmune response in which the body's immune system mistakenly attacks healthy tissue. Treatment for dermatomyositis typically involves medications to reduce inflammation and suppress the immune system, as well as physical therapy to help maintain muscle strength and function.

Masticatory muscles are a group of skeletal muscles responsible for the mastication (chewing) process in humans and other animals. They include:

1. Masseter muscle: This is the primary muscle for chewing and is located on the sides of the face, running from the lower jawbone (mandible) to the cheekbone (zygomatic arch). It helps close the mouth and elevate the mandible during chewing.

2. Temporalis muscle: This muscle is situated in the temporal region of the skull, covering the temple area. It assists in closing the jaw, retracting the mandible, and moving it sideways during chewing.

3. Medial pterygoid muscle: Located deep within the cheek, near the angle of the lower jaw, this muscle helps move the mandible forward and grind food during chewing. It also contributes to closing the mouth.

4. Lateral pterygoid muscle: Found inside the ramus (the vertical part) of the mandible, this muscle has two heads - superior and inferior. The superior head helps open the mouth by pulling the temporomandibular joint (TMJ) downwards, while the inferior head assists in moving the mandible sideways during chewing.

These muscles work together to enable efficient chewing and food breakdown, preparing it for swallowing and digestion.

The pterygoid muscles are a pair of muscles located in the deep part of the lateral aspect of the nasopharynx, in the human head. They are part of the group of muscles known as the muscles of mastication, which are involved in the chewing process.

There are two sets of pterygoid muscles: the medial and lateral pterygoids. The medial pterygoids are located deep within the jaw, near the temporomandibular joint (TMJ). They originate from the medial surface of the lateral pterygoid plate of the sphenoid bone and insert onto the inner aspect of the angle of the mandible (lower jawbone). The main function of the medial pterygoids is to assist in closing the jaw and moving it forward during chewing.

The lateral pterygoids, on the other hand, are located more superficially than the medial pterygoids and are situated near the TMJ. They have two heads: the upper head originates from the greater wing of the sphenoid bone, while the lower head arises from the lateral surface of the lateral pterygoid plate. The lateral pterygoids insert onto the front part of the neck of the mandible and the disc of the TMJ. Their main function is to assist in opening the jaw and moving it sideways during chewing.

Together, the pterygoid muscles play a crucial role in the movement and function of the jaw, allowing us to chew food effectively and speak clearly.

There is no medical definition for "dog diseases" as it is too broad a term. However, dogs can suffer from various health conditions and illnesses that are specific to their species or similar to those found in humans. Some common categories of dog diseases include:

1. Infectious Diseases: These are caused by viruses, bacteria, fungi, or parasites. Examples include distemper, parvovirus, kennel cough, Lyme disease, and heartworms.
2. Hereditary/Genetic Disorders: Some dogs may inherit certain genetic disorders from their parents. Examples include hip dysplasia, elbow dysplasia, progressive retinal atrophy (PRA), and degenerative myelopathy.
3. Age-Related Diseases: As dogs age, they become more susceptible to various health issues. Common age-related diseases in dogs include arthritis, dental disease, cancer, and cognitive dysfunction syndrome (CDS).
4. Nutritional Disorders: Malnutrition or improper feeding can lead to various health problems in dogs. Examples include obesity, malnutrition, and vitamin deficiencies.
5. Environmental Diseases: These are caused by exposure to environmental factors such as toxins, allergens, or extreme temperatures. Examples include heatstroke, frostbite, and toxicities from ingesting harmful substances.
6. Neurological Disorders: Dogs can suffer from various neurological conditions that affect their nervous system. Examples include epilepsy, intervertebral disc disease (IVDD), and vestibular disease.
7. Behavioral Disorders: Some dogs may develop behavioral issues due to various factors such as anxiety, fear, or aggression. Examples include separation anxiety, noise phobias, and resource guarding.

It's important to note that regular veterinary care, proper nutrition, exercise, and preventative measures can help reduce the risk of many dog diseases.

The temporalis muscle is a fan-shaped muscle located in the lateral aspect of the head, in the temporal fossa region. It belongs to the group of muscles known as muscles of mastication, responsible for chewing movements. The temporalis muscle has its origin at the temporal fossa and inserts into the coronoid process and ramus of the mandible. Its main function is to retract the mandible and assist in closing the jaw.

The masseter muscle is a strong chewing muscle in the jaw. It is a broad, thick, quadrilateral muscle that extends from the zygomatic arch (cheekbone) to the lower jaw (mandible). The masseter muscle has two distinct parts: the superficial part and the deep part.

The superficial part of the masseter muscle originates from the lower border of the zygomatic process of the maxilla and the anterior two-thirds of the inferior border of the zygomatic arch. The fibers of this part run almost vertically downward to insert on the lateral surface of the ramus of the mandible and the coronoid process.

The deep part of the masseter muscle originates from the deep surface of the zygomatic arch and inserts on the medial surface of the ramus of the mandible, blending with the temporalis tendon.

The primary function of the masseter muscle is to elevate the mandible, helping to close the mouth and clench the teeth together during mastication (chewing). It also plays a role in stabilizing the jaw during biting and speaking. The masseter muscle is one of the most powerful muscles in the human body relative to its size.

Syringomyelia is a medical condition characterized by the formation of a fluid-filled cavity or cavities (syrinx) within the spinal cord. This syrinx can lead to various symptoms depending on its size and location, which may include pain, muscle weakness, numbness, and stiffness in the neck, back, shoulders, arms, or legs. In some cases, it may also affect bladder and bowel function, sexual performance, and the ability to maintain normal body temperature. Syringomyelia is often associated with Chiari malformation, a condition where the lower part of the brain extends into the spinal canal. However, other conditions such as spinal cord injuries, tumors, or infections may also cause syringomyelia.
