However, it typically occurs when abnormal blood vessels, known as telangiectasias, develop in the retina. These vessels can leak fluid or blood into the retina, causing damage. Although some patients show no detectable telangiectasias, evidence of retinal damage can still be seen.<\/p>\n<p>JFT Type 2 is associated with:<\/p>\n<ul>\n<li>Equal occurrence in both men and women<\/li>\n<li>Typically affecting both eyes<\/li>\n<li>Most commonly appearing after age 40<\/li>\n<li>An increased prevalence in individuals with Type 2 diabetes or pre-diabetes<\/li>\n<\/ul>\n<p><strong>Diagnosis<\/strong><\/p>\n<p>Diagnosing JFT involves a thorough dilated retinal examination. A retina specialist will look for small bleeds, scarring, or abnormal blood vessels. Advanced diagnostic tools such as <strong>Optical Coherence Tomography (OCT) <\/strong>and <strong>Fluorescein Angiography<\/strong> are used to assess the extent of the condition. OCT provides high-resolution images of the retina, while fluorescein angiography helps identify abnormal and leaky blood vessels in the retina.<\/p>\n<p><strong>Macular scarring, retinal hemorrhages (bleeds), crystals and abnormal blood vessels characteristic of JFT Type 2.

Copyright American Society of Retina Specialists 2016<\/strong><\/p>\n<p><strong>Treatment and Prognosis<\/strong><\/p>\n<p>JFT may cause vision loss, especially if abnormal blood vessels leak fluid or bleed into the retina. This leakage can result in permanent damage or <strong>atrophy<\/strong> of retinal cells. However, treatments are available to help manage symptoms and prevent further vision loss:<\/p>\n<ul>\n<li><strong>Anti-VEGF injections<\/strong>: These medications, injected into the vitreous gel of the eye, help control leakage and fluid accumulation.<\/li>\n<li><strong>Focal\/grid laser treatment<\/strong>: Aimed at sealing leaking blood vessels.<\/li>\n<\/ul>\n<p>Despite its slow progression, most patients with JFT maintain useful vision in one or both eyes.<\/p>\n<p><strong>Conclusion<\/strong><\/p>\n<p>Idiopathic Juxtafoveolar Retinal Telangiectasis is a complex retinal condition that can lead to vision impairment. Early diagnosis and treatment are key to managing the disease and preventing permanent vision loss.
