    A 2016 Cochrane Review sought to determine the effectiveness of YAG laser iridotomy versus no laser iridotomy for pigment dispersion syndrome and pigmentary glaucoma, in 195 participants, across five studies. [5] No clear benefits in preventing loss of visual field were found for eyes treated with peripheral laser iridotomy. [5]

    Back of the eye of a person with mid-stage retinitis pigmentosa. Note pigment deposits in the mid periphery along with retinal atrophy. While the macula is preserved there is some loss of pigmentation around it. Specialty: Ophthalmology, Optometry: Symptoms: Trouble seeing at night, decreased peripheral vision [1] Usual onset: Childhood [1 ...

    This is an enlarged diagram showing the retinal pigment epithelium and its position in the eye. The retinal pigment epithelium (RPE) (see diagram) has an essential role in the eye. It secretes a large variety of factors including at least 22 proteins important in maintaining the structure, function and micro-environments on the two sides of the ...

    Fundus of geographic atrophy. Geographic atrophy (GA), also known as atrophic age-related macular degeneration (AMD) or advanced dry AMD, is an advanced form of age-related macular degeneration that can result in the progressive and irreversible loss of retinal tissue (photoreceptors, retinal pigment epithelium, choriocapillaris) which can lead to a loss of central vision over time.

  7. Maculopathy - Wikipedia

    en.wikipedia.org/wiki/Maculopathy

    Age-Related Macular Degeneration is a degenerative maculopathy associated with progressive sight loss. It is characterised by changes in pigmentation in the Retinal Pigment Epithelium, the appearance of drusen on the retina of the eye and choroidal neovascularization. AMD has two forms; 'dry' or atrophic/non-exudative AMD, and 'wet' or ...

    Acute posterior multifocal placoid pigment epitheliopathy primarily occurs in adults (with a mean age of 27). [1] Symptoms include blurred vision in both eyes, but the onset may occur at a different time in each eye. There are yellow-white placoid lesions in the posterior pole at the level of the retinal pigment epithelium. Some suggest a ...

    Ocular melanosis (OM) is a blue-gray and/or brown lesion of the conjunctiva that can be separated into benign conjunctival epithelial melanosis (BCEM) and primary acquired melanosis (PAM), of which the latter is considered a risk factor for uveal melanoma. [1]
