To reveal a case with branch retinal vein occlusion and branch retinal artery occlusion that occurred simultaneously.
Combined branch retinal artery occlusion (BRAO) and branch retinal vein occlusion (BRVO) is a rare condition that has been infrequently reported.
17 year-old girl without significant past medical history experienced burning, itching in her left eye few days prior to presentation. Her best-corrected visual acuities (BCVA) were 10/10 (Snellen scale) both in the right eye and left eye . Anterior segment examination was normal. Intraocular pressure by applanation tonometry were 15 mmHg and 14 mmHg in right and left eye respectively. Ishihara colour vision test revealed no abnormalities bilaterally. Funduscopy showed a normal right eye and retinal haemorrhages in the superotemporal region extending to the periphery with venous dilation and increased tortuosity, as well as ischaemic retinal regions possibly related to retinal artery branch occlusions in left eye. Fundus imaging showed retinal ischaemia and tortuous, dilated retinal veins in the left eye . In fundus fluorescein angiography (FFA), retinal arteries revealed areas absent of branches both in early and late phases . On the basis of these signs, BRVO and BRAO diagnosis were made. Humphrey Field Analyzer (HFA) revealed total inferior quadrant visual field defect in left eye.
Systemic diseases which might cause this condition were fully investigated. In two years follow-up, all ophthalmic signs and symptoms were resolved.
Combined BRVO and BRAO in young adults is a rare condition and should be investigated throughly for embolic sources and thrombophilic disorders. Patients may not present with decrease in visual acuity as in our case. For this reason detailed ophthalmologic examination is mandatory in every patient who presents to eye clinic.
