Acute idiopathic blind spot enlargement syndrome (AIBSE) is a rare eye disease affecting the retina of the eye. It is basically a type of retinopathy which affects females more than males. Currently there is no treatment for this condition, but, it is usually self limiting.
A scotoma may include and enlarge the normal blind spot. Even a small scotoma that happens to affect central or macular vision will produce a severe visual disability, whereas a large scotoma in the more peripheral part of a visual field may go unnoticed by the bearer because of the normal reduced optical resolution in the peripheral visual field.
I: Enlarged Blind Spot with Paracentral scotoma located 15 degrees superiorly These provide a statistical summary of the field with one number. Although not used for initial diagnosis, they are essential for monitoring glaucoma progression. [ 3 ]
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. It has been called the "silent thief of sight" because the loss of vision usually occurs slowly over a long period of time. [5]
It can progress to enlargement of the blind spot, blurring of vision, a concentric blind spot pattern, or diplopia (double vision). Ultimately, total loss of vision can occur, as well as other patterns of permanent injury to the optic nerve .
The cup-to-disc ratio (often notated CDR) is a measurement used in ophthalmology and optometry to assess the progression of glaucoma. The optic disc is the anatomical location of the eye's "blind spot", the area where the optic nerve leave and blood vessels enter the retina. The optic disc can be flat or it can have a certain amount of normal ...
Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye [1]. A blind spot, scotoma, is an obscuration of the visual field.A particular blind spot known as the physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the ...
Multiple types of scotomas form inside Bjerrum's area, typically in patients with open-angle glaucoma. Of particular note is the arcuate scotoma (also known as the Bjerrums scotoma). It starts at the blind spot, arching over the macular area, and ends as a horizontal line nasally.
