Diseases, dysfunctions, or disorders of or located in the iris.
A grouping of three closely linked conditions: iris nevus (or Cogan-Reese) syndrome, Chandler Syndrome, and essential (progressive) iris atrophy. The most common features of this syndrome are the movement of endothelial cells off the cornea onto the iris leading to corneal swelling, distortion of the iris, and variable degrees of distortion of the pupil. The abnormal cell movement plugs fluid outflow channels of the eye causing GLAUCOMA.
Diseases of the cornea.
A layer of the cornea. It is the basal lamina of the CORNEAL ENDOTHELIUM (from which it is secreted) separating it from the CORNEAL STROMA. It is a homogeneous structure composed of fine collagenous filaments, and slowly increases in thickness with age.
Single layer of large flattened cells covering the surface of the cornea.
Examination of the angle of the anterior chamber of the eye with a specialized optical instrument (gonioscope) or a contact prism lens.
The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.
A characteristic symptom complex.
A scientific tool based on ULTRASONOGRAPHY and used not only for the observation of microstructure in metalwork but also in living tissue. In biomedical application, the acoustic propagation speed in normal and abnormal tissues can be quantified to distinguish their tissue elasticity and other properties.
The front third of the eyeball that includes the structures between the front surface of the cornea and the front of the VITREOUS BODY.
An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches. (Dictionary of Visual Science, 4th ed)
The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil. (Cline et al., Dictionary of Visual Science, 4th ed, p109)
A porelike structure surrounding the entire circumference of the anterior chamber through which aqueous humor circulates to the canal of Schlemm.
The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)
A ring of tissue extending from the scleral spur to the ora serrata of the RETINA. It consists of the uveal portion and the epithelial portion. The ciliary muscle is in the uveal portion and the ciliary processes are in the epithelial portion.
A form of glaucoma in which the intraocular pressure increases because the angle of the anterior chamber is blocked and the aqueous humor cannot drain from the anterior chamber.
Congenital absence of or defects in structures of the eye; may also be hereditary.

Iris diseases refer to a variety of conditions that affect the iris, which is the colored part of the eye that regulates the amount of light reaching the retina by adjusting the size of the pupil. Some common iris diseases include:

1. Iritis: This is an inflammation of the iris and the adjacent tissues in the eye. It can cause pain, redness, photophobia (sensitivity to light), and blurred vision.
2. Aniridia: A congenital condition characterized by the absence or underdevelopment of the iris. This can lead to decreased visual acuity, sensitivity to light, and an increased risk of glaucoma.
3. Iris cysts: These are fluid-filled sacs that form on the iris. They are usually benign but can cause vision problems if they grow too large or interfere with the function of the eye.
4. Iris melanoma: A rare type of eye cancer that develops in the pigmented cells of the iris. It can cause symptoms such as blurred vision, floaters, and changes in the appearance of the iris.
5. Iridocorneal endothelial syndrome (ICE): A group of rare eye conditions that affect the cornea and the iris. They are characterized by the growth of abnormal tissue on the back surface of the cornea and can lead to vision loss.

It is important to seek medical attention if you experience any symptoms of iris diseases, as early diagnosis and treatment can help prevent complications and preserve your vision.

Iridocorneal Endothelial Syndrome (ICES) is a rare, progressive condition that affects the eye's iris and endothelium - the cell layer lining the inner surface of the cornea. ICE syndrome is typically characterized by three distinct clinical presentations: iris nevus (or Cogan-Reese) syndrome, Chandler's syndrome, and essential iris atrophy.

Common features of ICE syndrome include:

1. Progressive distortion and contraction of the iris (iris atrophy or hole formation).
2. Visible deposits on the surface of the iris (iris nevus).
3. Swelling and deterioration of the corneal endothelium, which can lead to decreased vision, corneal edema, and clouding.
4. Glaucoma development due to blockage of the eye's drainage angle by the iris changes or peripheral anterior synechiae (adhesions between the iris and cornea).

ICES primarily affects young to middle-aged women and is typically unilateral (affecting one eye). The exact cause of ICE syndrome remains unknown, but it's believed to be related to abnormalities in the endothelial cell layer. Currently, there is no definitive treatment for ICE syndrome. Management focuses on addressing symptoms and complications such as controlling intraocular pressure and monitoring for glaucoma progression.

Corneal diseases are a group of disorders that affect the cornea, which is the clear, dome-shaped surface at the front of the eye. The cornea plays an important role in focusing vision, and any damage or disease can cause significant visual impairment or loss. Some common types of corneal diseases include:

1. Keratoconus: A progressive disorder in which the cornea thins and bulges outward into a cone shape, causing distorted vision.
2. Fuchs' dystrophy: A genetic disorder that affects the inner layer of the cornea called the endothelium, leading to swelling, cloudiness, and decreased vision.
3. Dry eye syndrome: A condition in which the eyes do not produce enough tears or the tears evaporate too quickly, causing discomfort, redness, and blurred vision.
4. Corneal ulcers: Open sores on the cornea that can be caused by infection, trauma, or other factors.
5. Herpes simplex keratitis: A viral infection of the cornea that can cause recurrent episodes of inflammation, scarring, and vision loss.
6. Corneal dystrophies: Inherited disorders that affect the structure and clarity of the cornea, leading to visual impairment or blindness.
7. Bullous keratopathy: A condition in which the endothelium fails to pump fluid out of the cornea, causing it to swell and form blisters.
8. Corneal trauma: Injury to the cornea caused by foreign objects, chemicals, or other factors that can lead to scarring, infection, and vision loss.

Treatment for corneal diseases varies depending on the specific condition and severity of the disease. Options may include eyedrops, medications, laser surgery, corneal transplantation, or other treatments.

The Descemet membrane is the thin, transparent basement membrane that is produced by the corneal endothelial cells. It is located between the corneal stroma and the corneal endothelium, which is the innermost layer of the cornea. The Descemet membrane provides structural support for the corneal endothelium and helps to maintain the proper hydration and clarity of the cornea. It is named after the French physician Jean Descemet, who first described it in 1752.

The endothelium of the cornea is the thin, innermost layer of cells that lines the inner surface of the cornea, which is the clear, dome-shaped structure at the front of the eye. This single layer of specialized cells is essential for maintaining the transparency and proper hydration of the cornea, allowing light to pass through it and focus on the retina.

The endothelial cells are hexagonal in shape and have tight junctions between them, creating a semi-permeable barrier that controls the movement of water and solutes between the corneal stroma (the middle layer of the cornea) and the anterior chamber (the space between the cornea and the iris). The endothelial cells actively pump excess fluid out of the cornea, maintaining a delicate balance of hydration that is critical for corneal clarity.

Damage to or dysfunction of the corneal endothelium can result in corneal edema (swelling), cloudiness, and loss of vision. Factors contributing to endothelial damage include aging, eye trauma, intraocular surgery, and certain diseases such as Fuchs' dystrophy and glaucoma.

Gonioscopy is a diagnostic procedure in ophthalmology used to examine the anterior chamber angle, which is the area where the iris and cornea meet. This examination helps to evaluate the drainage pathways of the eye for conditions such as glaucoma. A special contact lens called a goniolens is placed on the cornea during the procedure to allow the healthcare provider to visualize the angle using a biomicroscope. The lens may be coupled with a mirrored or prismatic surface to enhance the view of the angle. Gonioscopy can help detect conditions like narrow angles, closed angles, neovascularization, and other abnormalities that might contribute to glaucoma development or progression.

In medical terms, the iris refers to the colored portion of the eye that surrounds the pupil. It is a circular structure composed of thin, contractile muscle fibers (radial and circumferential) arranged in a regular pattern. These muscles are controlled by the autonomic nervous system and can adjust the size of the pupil in response to changes in light intensity or emotional arousal. By constricting or dilating the iris, the amount of light entering the eye can be regulated, which helps maintain optimal visual acuity under various lighting conditions.

The color of the iris is determined by the concentration and distribution of melanin pigments within the iris stroma. The iris also contains blood vessels, nerves, and connective tissue that support its structure and function. Anatomically, the iris is continuous with the ciliary body and the choroid, forming part of the uveal tract in the eye.

A syndrome, in medical terms, is a set of symptoms that collectively indicate or characterize a disease, disorder, or underlying pathological process. It's essentially a collection of signs and/or symptoms that frequently occur together and can suggest a particular cause or condition, even though the exact physiological mechanisms might not be fully understood.

For example, Down syndrome is characterized by specific physical features, cognitive delays, and other developmental issues resulting from an extra copy of chromosome 21. Similarly, metabolic syndromes like diabetes mellitus type 2 involve a group of risk factors such as obesity, high blood pressure, high blood sugar, and abnormal cholesterol or triglyceride levels that collectively increase the risk of heart disease, stroke, and diabetes.

It's important to note that a syndrome is not a specific diagnosis; rather, it's a pattern of symptoms that can help guide further diagnostic evaluation and management.

Acoustic microscopy is a non-invasive imaging technique that uses sound waves to visualize and analyze the structure and properties of various materials, including biological samples. In the context of medical diagnostics and research, acoustic microscopy can be used to examine tissues, cells, and cellular components with high resolution, providing valuable information about their mechanical and physical properties.

In acoustic microscopy, high-frequency sound waves are focused onto a sample using a transducer. The interaction between the sound waves and the sample generates echoes, which contain information about the sample's internal structure and properties. These echoes are then recorded and processed to create an image of the sample.

Acoustic microscopy offers several advantages over other imaging techniques, such as optical microscopy or electron microscopy. For example, it does not require staining or labeling of samples, which can be time-consuming and potentially damaging. Additionally, acoustic microscopy can provide high-resolution images of samples in their native state, allowing researchers to study the effects of various treatments or interventions on living cells and tissues.

In summary, acoustic microscopy is a non-invasive imaging technique that uses sound waves to visualize and analyze the structure and properties of biological samples with high resolution, providing valuable information for medical diagnostics and research.

The anterior eye segment refers to the front portion of the eye, which includes the cornea, iris, ciliary body, and lens. The cornea is the clear, dome-shaped surface at the front of the eye that refracts light entering the eye and provides protection. The iris is the colored part of the eye that controls the amount of light reaching the retina by adjusting the size of the pupil. The ciliary body is a muscle that changes the shape of the lens to focus on objects at different distances. The lens is a transparent structure located behind the iris that further refracts light to provide a clear image. Together, these structures work to focus light onto the retina and enable vision.

Glaucoma is a group of eye conditions that damage the optic nerve, often caused by an abnormally high pressure in the eye (intraocular pressure). This damage can lead to permanent vision loss or even blindness if left untreated. The most common type is open-angle glaucoma, which has no warning signs and progresses slowly. Angle-closure glaucoma, on the other hand, can cause sudden eye pain, redness, nausea, and vomiting, as well as rapid vision loss. Other less common types of glaucoma also exist. While there is no cure for glaucoma, early detection and treatment can help slow or prevent further vision loss.

The anterior chamber is the front portion of the eye, located between the cornea (the clear front "window" of the eye) and the iris (the colored part of the eye). It is filled with a clear fluid called aqueous humor that provides nutrients to the structures inside the eye and helps maintain its shape. The anterior chamber plays an important role in maintaining the overall health and function of the eye.

The trabecular meshwork is a specialized tissue located in the anterior chamber angle of the eye, near the iris and cornea. It is composed of a network of interconnected beams or trabeculae that provide support and structure to the eye. The primary function of the trabecular meshwork is to regulate the outflow of aqueous humor, the fluid that fills the anterior chamber of the eye, and maintain intraocular pressure within normal ranges.

The aqueous humor flows from the ciliary processes in the posterior chamber of the eye through the pupil and into the anterior chamber. From there, it drains out of the eye through the trabecular meshwork and into the canal of Schlemm, which leads to the venous system. Any obstruction or damage to the trabecular meshwork can lead to an increase in intraocular pressure and potentially contribute to the development of glaucoma, a leading cause of irreversible blindness worldwide.

The cornea is the clear, dome-shaped surface at the front of the eye. It plays a crucial role in focusing vision. The cornea protects the eye from harmful particles and microorganisms, and it also serves as a barrier against UV light. Its transparency allows light to pass through and get focused onto the retina. The cornea does not contain blood vessels, so it relies on tears and the fluid inside the eye (aqueous humor) for nutrition and oxygen. Any damage or disease that affects its clarity and shape can significantly impact vision and potentially lead to blindness if left untreated.

The ciliary body is a part of the eye's internal structure that is located between the choroid and the iris. It is composed of muscle tissue and is responsible for adjusting the shape of the lens through a process called accommodation, which allows the eye to focus on objects at varying distances. Additionally, the ciliary body produces aqueous humor, the clear fluid that fills the anterior chamber of the eye and helps to nourish the eye's internal structures. The ciliary body is also responsible for maintaining the shape and position of the lens within the eye.

Angle-closure glaucoma is a type of glaucoma that is characterized by the sudden or gradually increasing pressure in the eye (intraocular pressure) due to the closure or narrowing of the angle between the iris and cornea. This angle is where the drainage system of the eye, called the trabecular meshwork, is located. When the angle becomes too narrow or closes completely, fluid cannot properly drain from the eye, leading to a buildup of pressure that can damage the optic nerve and cause permanent vision loss.

Angle-closure glaucoma can be either acute or chronic. Acute angle-closure glaucoma is a medical emergency that requires immediate treatment to prevent permanent vision loss. It is characterized by sudden symptoms such as severe eye pain, nausea and vomiting, blurred vision, halos around lights, and redness of the eye.

Chronic angle-closure glaucoma, on the other hand, develops more slowly over time and may not have any noticeable symptoms until significant damage has already occurred. It is important to diagnose and treat angle-closure glaucoma as early as possible to prevent vision loss. Treatment options include medications to lower eye pressure, laser treatment to create a new opening for fluid drainage, or surgery to improve the flow of fluid out of the eye.

Eye abnormalities refer to any structural or functional anomalies that affect the eye or its surrounding tissues. These abnormalities can be present at birth (congenital) or acquired later in life due to various factors such as injury, disease, or aging. Some examples of eye abnormalities include:

1. Strabismus: Also known as crossed eyes, strabismus is a condition where the eyes are misaligned and point in different directions.
2. Nystagmus: This is an involuntary movement of the eyes that can be horizontal, vertical, or rotatory.
3. Cataracts: A cataract is a clouding of the lens inside the eye that can cause vision loss.
4. Glaucoma: This is a group of eye conditions that damage the optic nerve and can lead to vision loss.
5. Retinal disorders: These include conditions such as retinal detachment, macular degeneration, and diabetic retinopathy.
6. Corneal abnormalities: These include conditions such as keratoconus, corneal ulcers, and Fuchs' dystrophy.
7. Orbital abnormalities: These include conditions such as orbital tumors, thyroid eye disease, and Graves' ophthalmopathy.
8. Ptosis: This is a condition where the upper eyelid droops over the eye.
9. Color blindness: A condition where a person has difficulty distinguishing between certain colors.
10. Microphthalmia: A condition where one or both eyes are abnormally small.

These are just a few examples of eye abnormalities, and there are many others that can affect the eye and its functioning. If you suspect that you have an eye abnormality, it is important to consult with an ophthalmologist for proper diagnosis and treatment.

Intraocular pressure (IOP) is the fluid pressure within the eye, specifically within the anterior chamber, which is the space between the cornea and the iris. It is measured in millimeters of mercury (mmHg). The aqueous humor, a clear fluid that fills the anterior chamber, is constantly produced and drained, maintaining a balance that determines the IOP. Normal IOP ranges from 10-21 mmHg, with average values around 15-16 mmHg. Elevated IOP is a key risk factor for glaucoma, a group of eye conditions that can lead to optic nerve damage and vision loss if not treated promptly and effectively. Regular monitoring of IOP is essential in diagnosing and managing glaucoma and other ocular health issues.

  • Stevens-Johnson syndrome can cause painful corneal blisters and even holes, leading to vision loss. (wjgarvinod.com)
  • This syndrome is caused by a deletion of the short arm of chromosome 11, with the loss of both the PAX6 and WT1 genes. (uiowa.edu)
  • Peripheral and central pulse pressure and augmentation index were determined at rest, and global endothelial function was measured using pulse wave analysis and administration of sublingual nitroglycerin and inhaled albuterol. (dokumen.tips)
  • Severe retinal vasculitis as a manifestation of poststreptococcal syndrome in a child. (auckland.ac.nz)
  • However, the relationship between endothelial function and definitive measures of arterial stiffness and wave reflections has not been described in healthy individuals. (dokumen.tips)
  • Therefore, we tested the hypothesis that endothelial function is inversely correlated with aortic pulse wave velocity (PWV), central pulse pressure, and augmentation index in healthy individuals. (dokumen.tips)
  • In a separate group of subjects (n 89), aortic PWV was measured and brachial artery flow-mediated dilatation assessed as a measure of conduit artery endothelial function. (dokumen.tips)
  • After adjusting for potential confounders, global endothelial function remained independently and inversely associated with aortic PWV and augmentation index. (dokumen.tips)
  • There was also a significant, inverse relationship between conduit artery endothelial function and aortic PWV ( r 0.39, P 0.001), which remained independent after adjusting for confounding factors. (dokumen.tips)
  • In healthy individuals, a decline in endothelial function is associated with increased large artery stiffness, wave reflections, and central pulse pressure. (dokumen.tips)
  • Support for this hypothesis stems from the observation that brachial artery pulse pressure, a surrogate measure of large artery stiffness, correlates with coronary 19 and resistance vessel 20 endothelial function in hypertensive patients and controls. (dokumen.tips)
  • The three variants of ICE syndromes share the same pathogenic mechanism, which is characterised by the normal corneal endothelial cells being replaced with more epithelial-like cells that migrate into the surrounding tissues. (uk.com)
  • Other serious conditions that can change the color of the eye due to its link to the iris include iridocorneal endothelial syndrome (ICE), pigment dispersion syndrome, uveitis, and Horner's Syndrome. (oceaneyesc.com)
  • Pigment dispersion syndrome, also know as pigment loss according to the AAO, is the loss of pigment from the back of the iris. (oceaneyesc.com)
  • Stevens--Johnson syndrome (SJS), also called erythema multiforme major, is a rare skin disorder that also affects the eyes. (nih.gov)
  • Stevens-Johnson syndrome can cause painful corneal blisters and even holes, leading to vision loss. (optometricassoc.com)
  • There are also a number of less common diseases that can affect the cornea - including ocular herpes, Stevens-Johnson Syndrome, iridocorneal endothelial syndrome, and pterygium. (nih.gov)
