This is a stunning picture of a hemivein occlusion taken by our chief photographer, Mr. James Soque. This condition, hemivein occlusion, is typically caused by high blood pressure. It is also associated with high cholesterol and diabetes. The small retinal veins get damaged from these conditions. This leads to turbulent blood flow, which in turn leads to a thrombosis in the vessel and decreased blood to the tissues. The retina responds to this with swelling(edema), intraretinal hemorrhages and exudation of lipoprotein from the blood. Vision drops. Luckily, there is treatment which includes intraocular injections with various drugs such as anti-VEGF and steroids. We also use laser therapy. Keeping blood pressure, cholesterol and blood sugar under control is critical to prevent retinal disease.
