Low vision due to persistent Cloquet’s canal

Abstract

The Cloquet’s canal (CC) is the remnant of the primary vitreous and it disappears in the intrauterine developmental period of an eye. Rarely it can persist in mature eyes and cause low visual acuity. We detected a persistent CC and low visual acuity in a 36 year-old patient. Fundus fl uorescein angiography and optical coherence tomography examinations were completely normal in our case and low visual acuity was directly associated with opacifi cation of the fi brovascular persistent CC tissue. Persistent CC can cause low visual acuity due to directly media opacity effect of fi brovascular tissue without any complication.
