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.
Chorioretinitis is an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye. It is a form of posterior uveitis.Inflammation of these layers can lead to vision-threatening complications.
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.
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).
The definition of the classes and Frisén scale used for optic disc edema diagnosis are listed below: Class 0 < 0.50 diopter cycloplegic refractive change; No evidence of optic-disc edema, nerve sheath distention, choroidal folds, globe flattening, scotoma or cotton-wool spots compared to baseline; Class 1 Repeat OCT and visual acuity in 6 weeks

Toxic optic neuropathy refers to the ingestion of a toxin or an adverse drug reaction that results in vision loss from optic nerve damage. Patients may report either a sudden loss of vision in both eyes, in the setting of an acute intoxication, or an insidious asymmetric loss of vision from an adverse drug reaction.
