It typically affects both eyes, as it is not a problem specific to one eye. [5] [6] The affected area flickers but is not dark. It then gradually expands outward ...
Every normal mammalian eye has a scotoma in its field of vision, usually termed its blind spot. This is a location with no photoreceptor cells, where the retinal ganglion cell axons that compose the optic nerve exit the retina. This location is called the optic disc. There is no direct conscious awareness of visual scotomas. They are simply ...

The diagnosis of POHS is based on the clinical triad of multiple white, atrophic choroidal scars, peripapillary pigment changes (dark spots around optic disc of the eye), and a maculopathy caused by choroidal neovascularization.

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.
