Evaluate of retinal exudate of brunch retinal vain occulusion with OCT angiography

Abstract

Purpose : Treatment for macula edema of retinal vascular occlusion is usualy used by anti-vascular endothelial growth factor. But old retinal vascular occlusion makes exudate of retina. This exudate causes lower visual acuity of patients. We examed relationship between microaneurysms measured by OCT angiography and exudate by fundus photograph.

Methods : Twenty two eyes of 22 patients with old branch retinal vascular occlusion after 3months later from onset are examined with OCT angiography and fundus photograph From April to June in 2017.
We examined these patients appearance of microaneurysms and axudute with OCT angiography, fundus photo and flouresein angiography. The primary endpoints are visual acuity, appearance of exudute, and microaneurysms.

Results : Twenty two cases avarage of age are 72.7 ± 22. 17 eyes are found exdute and 22 eyes are mesured microaneurysms. Ten eyes are examined microaneurysms with fluorescein angiography. Microaneurysms examed with fluorescein angiography are asociate OCTA. And exdute are appeares near capillary nodules.

Conclusions : It is suggested that capillary nodules on OCTA may cause exudutes.
