Latanaprost (eye drops) Pigment dispersion syndrome (PDS) is an eye disorder that can lead to a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. Over time, these pigment cells can accumulate in the anterior chamber in such a way that they ...
The crystalline lens inside the human eye has been implicated as a causative factor in many forms of glaucoma. Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens. It is a type of secondary glaucoma.
Secondary glaucoma is a progressive optic nerve disorder which results in complete loss of vision. Secondary glaucoma is a collection of progressive optic nerve disorders associated with a rise in intraocular pressure (IOP) which results in the loss of vision. In clinical settings, it is defined as the occurrence of IOP above 21 mmHg requiring ...
Medication, laser, surgery [1] Frequency. 6–67 million [2][4] Glaucoma is a group of eye diseases that can lead to damage of the optic nerve. The optic nerve transmits visual information from the eye to the brain. Glaucoma may cause vision loss if left untreated.
1 in 4,000 people [1] Retinitis pigmentosa (RP) is a member of a group of genetic disorders called inherited retinal dystrophy (IRD) that cause loss of vision. [1] Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). [1] As peripheral vision worsens, people may experience "tunnel ...
Sampaolesi line is a sign which may be observed during a clinical eye examination. During gonioscopy (where the structures of the eye's anterior segment are examined), if an abundance of brown pigment is seen at or anterior to Schwalbe's line, a Sampaolesi line is said to be present. [1][2][3] The presence of a Sampaolesi line can signify ...
Specialty. Ophthalmology. Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes. Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
The triad of CPEO, bilateral pigmentary retinopathy, and cardiac conduction abnormalities was first described in a case report of two patients in 1958 by Thomas P. Kearns (1922–2011), MD., and George Pomeroy Sayre (1911–1992), MD. [22] A second case was published in 1960 by Jager and co-authors reporting these symptoms in a 13-year-old boy ...
