Long term, it can affect vision through inflammation, leakage of fluid, and formation of new vessels.<\/p>\n<h3><strong>PATHOGENESIS<\/strong><\/h3>\n<ul>\n<li><strong>Microangiopathy<\/strong> leading to hypoxia and retinitis proliferans.<\/li>\n<li>Vascular leakage, causing retinal edema, hemorrhages, and hard exudates.<\/li>\n<li>Formation of new blood vessels (neovascularization) due to ischemia.<\/li>\n<\/ul>\n<h3><strong>Stages of Diabetic Retinopathy<\/strong><\/h3>\n<ol>\n<li><strong> Mild Nonproliferative Retinopathy<\/strong><\/li>\n<\/ol>\n<p>In the first phase, small regions of ballooning of the retinal blood vessels<strong> (microaneurysms)<\/strong> occur. They leak fluid but do not affect vision. In most people with this phase, there are <strong>no symptoms<\/strong>, but it can be found during routine eye examinations. In this stage, the disease is not serious and can be left untreated, but regulation of blood sugar prevents the progression.<\/p>\n<ol start=\"2\">\n<li><strong> Moderate Nonproliferative Retinopathy<\/strong><\/li>\n<\/ol>\n<p>In the second stage, the damage to the blood vessels is more extensive. Part of the vessels becomes blocked, and the blood cannot travel to the retina in such areas. This decreased oxygenation of the retina predisposes the retina to damage. In this stage, patients notice some changes in vision. Regular follow-up on a regular basis by an ophthalmologist is recommended in order to prevent worsening of the condition.<\/p>\n<ol start=\"3\">\n<li><strong> Advanced Nonproliferative Retinopathy<\/strong><\/li>\n<\/ol>\n<p>In this phase, more blood vessels are blocked, and there is a severe deficiency of oxygen within the retina. The retina forms new, immature blood vessels to compensate for the poor oxygenation. New blood vessels are fragile and prone to leaking blood into the retina. Patients experience difficulties with their vision, like blurry vision, night blindness, or dark spots in their eyes.<\/p>\n<ol start=\"4\">\n<li><strong> Proliferative Diabetic Retinopathy (PDR)<\/strong><\/li>\n<\/ol>\n<p>The most advanced type of diabetic retinopathy, proliferative diabetic retinopathy, is when the retina forms new, abnormal blood vessels. These are extremely fragile blood vessels and susceptible to leakage and blinding. The new tissue can be generated, which can make the retina detached and hence lead to irreversible loss of vision. Proliferative diabetic retinopathy needs immediate medical care to avoid permanent damage.<\/p>\n<blockquote><p><strong>Read more:<\/strong>\u00a0<strong><a href=\"https:\/\/www.nextillo.com\/blog\/category\/blog\/ophthalmology\/\" target=\"_blank\" rel=\"noopener\">Ophthalmology Blogs<\/a>\u00a0for Fmge and Neet PG Preparation<\/strong><\/p><\/blockquote>\n<h3><strong>Diabetic Maculopathy<\/strong><\/h3>\n<p>It involves changes in the macular region affecting central vision.<\/p>\n<h3><strong>Diagnosis<\/strong><\/h3>\n<p><strong>\u00a0Fluorescein Angiography<\/strong><\/p>\n<p>Dye is infused through a vein in the arm, and a camera captures an image of the retina as the dye flows through the blood vessels.<\/p>\n<p><strong>\u00a0Optical Coherence Tomography (OCT)<\/strong><\/p>\n<p>OCT is a non-invasive imaging procedure that uses light waves to give detailed cross-sectional views of the retina.
