Overview
Idiopathic juxtafoveal retinal telangiectasia (IJT) is a rare condition of the eyes caused by dilated or twisting blood vessels (telangiectasia) and malfunctioning capillaries (tiny blood vessels) near the fovea in the retina. The fovea is the region of the retina with the highest concentration of special retinal nerve cells, called cones, which produce sharp, daytime vision. In IJT, the telangiectasias cause fluid or crystal buildup and swelling, or otherwise impair how light is normally reflected through the eye resulting in progressive vision loss.[1][2][3][4] It may be congenital (present at birth) or acquired. Laser photocoagulation maybe helpful in restoring and preserving central visual acuity for individuals with certain subtypes of IJT.[2]
