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]
A unilateral decrease in visual acuity is the most common symptom of toxoplasmic retinitis. Under ophthalmic examination, toxoplasmic chorioretinitis classically appears as a focal, white retinitis with overlying moderate inflammation of the vitreous humour.
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 ...
Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness. The retina is the eye's "sensing" tissue. Retinitis may be caused by a number of different infectious agents. Its most common form, called retinitis pigmentosa, has a prevalence of one in every 2,500–7,000 people.
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.
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.
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.

Progressive outer retinal necrosis (PORN) syndrome is a form of chorioretinitis, an infection in the retina, the back of the eye.The disease is most commonly caused by the varicella zoster virus and is found almost exclusively in patients with HIV/AIDS (acquired immunodeficiency syndrome).
