Study Notes
Optic Atrophy
-
Primary Optic Atrophy is caused by damage behind the eye, characterized by pale white color, well-defined edges, atrophic and enlarged cup, and normal retinal vessels and background, often associated with pituitary tumors, retrobulbar neuritis, optic nerve trauma, and toxic amblyopia.
-
Secondary Optic Atrophy has a pale grey color with well-defined edges, atrophic and enlarged cup, and sheathed retinal vessels, commonly seen in post-neuritic and post-papilledemic cases.
Characteristics of Optic Atrophy
-
Consecutive Optic Atrophy is caused by retinal diseases, such as retinitis pigmentosa, neglected retinal detachment, and CRAO, and is characterized by pale waxy yellow color, slightly irregular edges, obliterated atrophic cup, and attenuated and sheathed retinal vessels.
-
Post Glaucomatous Optic Atrophy is associated with absolute glaucoma, featuring pale white color, well-defined edges, deep and undermined cup, and shifted nasally retinal vessels.
