Abstract Details


To present a case of spontaneous vitreous haemorrhage in a young adult patient with bilateral congenital prepapillary vascular loops


Ulucanlar Eye Training and Research Hospital, Ankara, Turkey


We present a 41-year-old man with vitreous haemorrhage secondary to congenital prepapillary vascular loops on his right eye. His past systemic and ophthalmic history was unremarkable.


A 41-year-old man visited our clinic due to sudden onset of floaters in his right eye. On examination, the best-corrected visual acuity was 20/20 on both eyes. The intraocular pressure was within normal range bilaterally. The anterior segments of both eyes were normal on slit-lamp biomicroscopy. Examination of the right fundus showed several looped or coiled peripapillary retinal vessels with small amount of vitreous haemorrhage. The left fundus showed similar prepapillary vascular loops. Fluorescein angiography revealed that all the looped/coiled peripapillary retinal vessels were part of the branches of the central retinal artery. No leakage was noted from the looped/coiled vessels and the other retinal vessels. Four weeks after the initial visit, the vitreous haemorrhage had disappeared at fundus examination. During the follow-up periods, there was no morphological change of the vessels.


Congenital prepapillary vascular loops are thought be associated with an increased risk of preretinal and vitreous haemorrhage and should be kept in mind as a rare underlying cause of vitreous haemorrhage.
