pikaajalise suhkurtõve tagajärjel tekkinud silma võrkkesta ehk reetina kahjustus, mille tõttu inimese nägemine halveneb ja võib lõpuks täielikult kaduda
a disorder of the blood vessels of the retina occurring as a complication of poorly controlled diabetes mellitus and often leading to blindness
degenerative disease that used to account for a large proportion of blindness
Good to know
Varases arengujärgus diabeetiline retinopaatia nägemishäireid ei põhjusta, kuid oht nägemist kaotada on olemas. Kui diabeetiline retinopaatia avastatakse õigel ajal, saab haiguse arengut peatada või nägemist laserraviga säilitada.
Diabeetiline retinopaatia on I tüüpi (insuliinsõltuv diabeet) suhkruhaigete pimedaksjäämise peamine põhjus.
Two general types of diabetic eye disease are known and are characterized as nonproliferative diabetic retinopathy (which lacks abnormal blood vessel growth) and proliferative diabetic retinopathy (in which abnormal blood vessels are present in the retina and sometimes the iris).
The nonproliferative form is characterized by dilation of the retinal veins and microaneurysms which may leak blood cells and/or plasma, causing internal hemorrhaging or edema in the retina. ... In proliferative diabetic retinopathy new blood vessels form near the optic disk, break through the inner membranous lining, and grow on the vitreous chamber and elsewhere in the retina and may rupture, causing gross vitreous hemorrhage.
