[QUOTE="cugila, post: 95678, member: 15325"] Hi secrettheatre. [b]Diabetic Maculopathy.[/b] This condition is more common in older, non-insulin dependent diabetics, and is the most common cause of gradual loss of vision in a patient with non-proliferative diabetic retinopathy. This involves the breakdown of the bloodretinal barrier leakage of plasma from small blood vessels in the macula swelling of the central retina formation of hard exudates diabetic macular oedema does not cause total blindness o leads to severe loss of central vision (1) clinically significant macular oedema is retinal thickening and/or adjacent hard exudates that either involve the center of the macula Four types of diabetic maculopathy are recognised: cystoid: characterised by microaneurysms and haemorrhages but relatively few, if any, hard exudates the main feature is extensive macular oedema which if persistent, may lead to a lamellar hole at the fovea with permanent impairment of visual acuity focal - a background diabetic retinopathy, associated with macular oedema and surrounding hard exudates ischaemic - similar ophthalmic picture to cystoid and differentiated from it by fluorescein angiography mixed - exudates, oedema and ischaemia Reference: Frank RN. Diabetic Retinopathy.N Engl J Med 2004;350:48. Here is a link to a website which explains in more detail: [url=http://medweb.bham.ac.uk/easdec/diabetic_maculopathy.html]http://medweb.bham.ac.uk/easdec/diabeti ... pathy.html[/url] [/QUOTE]
