What is retinal telangiectasia?
Retinal telangiectasia is a disease that affects the retina. The retina is the light sensitive layer in the back of the eye. It captures the images coming through the front of the eye and then sends them to the brain.
What is idiopathic Parafoveal telangiectasia?
Idiopathic juxtafoveolar telangiectasis (also known as idiopathic parafoveal, perifoveal or macular telangiectasia or telangiectasis) is a descriptive term for various disease entities presenting with incompetence, ectasia, and/or irregular dilations of the capillary network affecting only the juxtafoveolar region of …
What causes telangiectasia in the eye?
Macular telangiectasia (MacTel) is a disease that affects the macula, causing central vision loss. It’s caused by abnormal blood vessels around the fovea. The fovea is the centre of the macula and is used for detailed central vision.
Where is Juxtafoveal?
The fovea is the small area at the center of the macula, the part of the retina that gives us our sharpest vision. In IJT the retinal blood vessels just next to the fovea become abnormally larger and twisted. These changes are similar to those seen in varicose veins, but on a tiny scale.
Is macular telangiectasia the same as macular degeneration?
MacTel is sometimes mistaken for age-related macular degeneration, due to similar patterns of neovascularization in both diseases. MacTel is a bilateral disease. Fellow eyes are usually similarly affected by the disease, showing the same pathological features.
What is GA in ophthalmology?
Geographic atrophy (GA), is an advanced form of age-related macular degeneration (AMD), affecting the retina, a part of the eye that sends information to the brain to enable sight.
What is MacTel?
Listen. Macular telangiectasia (MacTel) type 2 is an eye disease affecting the macula that causes loss of central vision. In this disease, the tiny blood vessels (capillaries) around the fovea, an area in the center of the macula where eyesight is the sharpest, widen and leak.
What is para macular?
Background: Paramacular coloboma (plural: colobomata) is a solitary oval football or torpedo-shaped chorioretinal lesion located temporal to the fovea in one or both eyes. Previous case reports have speculated varying etiology, but few have justified its pathognomonic shape and location.
How common is macular telangiectasia?
Epidemiology. MacTel is a bilateral disease that usually begins to affect patients between the ages of 40 and 60 years. The prevalence of MacTel is estimated to be 0.022% to 0.1%, based on assessment of fundus photographs from large population-based studies.
Is macular telangiectasia type 2 hereditary?
Macular telangiectasia type 2 is an idiopathic macular disease with characteristic clinical and imaging findings. It is widely accepted that MacTel can be a familial disease, and recent studies suggest that MacTel is dominantly inherited with incomplete penetrance.
What is juxtafoveal telangiectasis?
Idiopathic Juxtafoveal Telangiectasis. (pronounced tell an gee ACT te sis) (JFT), also known as perifoveal telangiectasis or mac-tel for macular telangiectasia, is a condition in which abnormalities develop in blood vessels at the center of the retina.
