A vitreo-retinal specialist (an ophthalmologist specialized in treatment of retinal diseases) should be consulted for proper management of the case. [ citation needed ] Presumed ocular histoplasmosis syndrome and age-related macular degeneration (AMD) have been successfully treated with laser, anti-vascular endothelial growth factors and ...
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. If only the choroid is inflamed, not the retina, the condition is termed choroiditis. [1]
Histoplasmosis is a fungal infection caused by Histoplasma capsulatum. [ 2 ] [ 3 ] Symptoms of this infection vary greatly, but the disease affects primarily the lungs . [ 4 ] Occasionally, other organs are affected; called disseminated histoplasmosis, it can be fatal if left untreated.
[10] Subretinal hemorrhage is caused by retinal and/or choroidal circulation. Significant subretinal hemorrhage occurs in several conditions, but is most commonly associated with age-related macular degeneration, presumed ocular histoplasmosis, high myopia, retinal arterial macroaneurysm, and trauma.

Toxoplasma infection can be prevented in large part by: cooking meat to a safe temperature (i.e., one sufficient to kill Toxoplasma) peeling or thoroughly washing fruits and vegetables before eating; cleaning cooking surfaces and utensils after they have contacted raw meat, poultry, seafood, or unwashed fruits or vegetables
Colour, where the retina is illuminated by white light and examined in full colour. Red free fundus photography utilizes a filter in order to better observe superficial lesions and some vascular abnormalities within the retina and surrounding tissue. A green filter ~540–570 nm is used to block out red wavelengths of light.
In an eye examination, light-colored spots on the retina are seen. Complete loss of visual acuity may happen [ citation needed ] The name of the condition comes from the small light-colored fundus spots on the retina, scattered in a pattern like birdshot from a shotgun , but these spots might not be present in early stages.
Indocyanine green angiography (ICGA), [10] and OCT angiography (OCTA) [11] [12] [13] studies have provided support for choriocapillaris involvement. However, a novel hypothesis was proposed implicating a direct neurotropic infection as a possible underlying cause given the dynamic changes observed along the neuronal pathway of the retina [ 14 ]
