Progressive bifocal chorioretinal atrophy, also known for its abbreviations PBCRA or CRAPB, [1] is a rare, slowly progressive, autosomal dominant syndrome characterized by relatively large-sized atrophic hole-shaped lesions in the macular and nasal retina, myopia, low visual acuity, and nystagmus.
Presumed ocular histoplasmosis syndrome (POHS) is a syndrome affecting the eye, which is characterized by peripheral atrophic chorioretinal scars, atrophy or scarring adjacent to the optic disc and maculopathy. The loss of vision in POHS is caused by choroidal neovascularization.
The retinal circulation, on the other hand, derives its circulation from the central retinal artery, also a branch of the ophthalmic artery, but passing in conjunction with the optic nerve. [3] They branch in a segmental distribution to end arterioles and not anastomoses. This is clinically significant for diseases affecting choroidal blood supply.
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
Cherry red spot in a person with central retinal artery occlusion. Central retinal artery occlusion is characterized by painless, acute vision loss in one eye. [1] Upon fundoscopic exam, one would expect to find: cherry-red spot (90%) (a morphologic description in which the normally red background of the choroid is sharply outlined by the swollen opaque retina in the central retina), retinal ...
The optic nerve can be damaged when exposed to direct or indirect injury. Direct optic nerve injuries are caused by trauma to the head or orbit that crosses normal tissue planes and disrupts the anatomy and function of the optic nerve; e.g., a bullet or forceps that physically injures the optic nerve.

Birdshot chorioretinopathy, now commonly named birdshot uveitis or HLA-A29 uveitis, [1] is a rare form of bilateral posterior uveitis affecting both eyes.It causes severe, progressive inflammation of both the choroid and retina.
