Profound abnormalities detected with visual field and multifocal electroretinography testing can be observed in the presence of a normal retinal appearance. Retinal examinations are advised for documentation, but visible bull's-eye maculopathy is a late change, [6] and the goal of screening is to recognize toxicity at an earlier stage. Annual ...
Amsler grid, Chart 1. There are 7 types of Amsler grid charts. All charts measure 10 cm × 10 cm (3.9 in × 3.9 in), which when viewed at a distance of 33 cm (13 in) from the eye can be used to measure defects in the central 20 degrees of the visual field. [3]

English: ETDRS Chart R, one of the three logMAR chart models designed by Ferris, Kassoff, Bresnick, and Bailey for use in the Early Treatment Diabetic Retinopathy Study (ETDRS). Chart and optotype dimensions in millimeters precisely as specified by Ferris et al. (1982). LogMAR and VAR values after Baliey & Lovie (2013).
Subjective measurement of blind spot enlargement is done using visual field testing. [4] In the early stages, using FFA peripapillary hyperfluorescence may be observed. [ 4 ] Since OCT can be used to observe the microstructural alterations in the outer retina, it is the gold standard in diagnosing AIBSES.
However, it may definitely be related to other diseases included in the white dot syndrome group. Acute zonal occult outer retinopathy occurs in young to middle age adults and may eventually progress to retinal cell death. Symptoms include acute visual field loss and photopsias. Suspected causes include autoimmune, viral, and fungal. [2] [5]
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
Researchers do not yet fully understand the disease, but it may be the result of cancer or cancer chemotherapy. [1] Autoimmune retinopathy is an autoimmune condition characterized by vision loss, blind spots, and visual field abnormalities. Autoimmune retinopathy can be divided into paraneoplastic (PAIR) or non-paraneoplastic (nPAIR). [2]
