Diabetic retinopathy (diabetic eye)<\/h1>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t

Diabetic retinopathy<\/span>(commonly known as diabetic eye) is one of the complications of diabetes. Improper blood sugar management damages the endothelium of retinal blood vessels, causing microfilament vasculopathy. The retina is covered with tiny blood vessels, and lesions can cause vascular obstruction and reduce the blood supply to the retina, resulting in hypoxia and triggering the growth of new blood vessels. Abnormally fragile new blood vessels can easily rupture, bleed, and leak into the vitreous body. Hypoxia in the retina can lead to edema and death of optic nerve cells, resulting in vision loss. Diabetic eye can cause a series of pathologies such asglaucoma symptoms<\/a>, retinal detachment, which may cause severe vision loss.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

People with diabetes are at higher risk of developing diabetic eye disease compared with the general population. It is recommended to have a diabetic eye examination once a year, and to keep blood sugar, blood pressure, and cholesterol levels under control. If diabetic eye disease does develop, the following treatment approaches may help improve the condition:<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Apply laser to destroy oxygen-deficient retina to prevent the growth of diseased blood vessels and to reduce leakage. The treatment also stimulates the peripheral retinal cells to absorb water, reducing the condition of macular oedema.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Inject anti-VEGF drugs into the vitreous to help inhibit vascular proliferation and vascular endothelial growth in the eye. It is expected to improve vision by reducing vascular leakage and bleeding.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In severe cases such as retinal detachment, intraocular haemorrhage or persistent macular oedema, vitrectomy can help restore vision. However, this is a complex procedure with a success rate ranging from 50% to 80%, depending on the individual case.<\/p>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
