Gass described the 'AZOOR complex' which consists of multiple evanescent white dot syndrome, nultifocal choroiditis, punctate inner choroiditis, acute idiopathic blind spot enlargement, acute macular neuroretinopathy, acute annular outer retinopathy, and acute zonal occult outer retinopathy. He suggested these diseases represent one disease due ...
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 ...
Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy.
Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is an acquired inflammatory uveitis that belongs to the heterogenous group of white dot syndromes in which light-coloured (yellowish-white) lesions begin to form in the macular area of the retina.
The incidence of age-related macular degeneration and its associated features increases with age and is low in people <55 years of age. [101] Smoking is the strongest modifiable risk factor. [102] As of 2008, age-related macular degeneration accounts for more than 54% of all vision loss in the white population in the US. [103]
Left eye retina photograph shows moving nematode larva at the macular area [1] Diffuse unilateral subacute neuroretinitis ( DUSN ) is a rare condition that occurs in otherwise healthy, often young patients and is due to the presence of a subretinal nematode .
Macular scarring is formation of the fibrous tissue in place of the normal retinal tissue on the macular area of the retina which provides the sharpest vision in the eyes. It is usually a result of an inflammatory or infectious process. [1] Other etiologies include macular pucker (macular detachment), macular hole, and age-related macular ...
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.
