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 fluorescein angiography and optical coherence tomography examinations were completely normal in our case and low visual acuity was directly associated with opacification of the fibrovascular persistent CC tissue. Persistent CC can cause low visual acuity due to directly media opacity effect of fibrovascular tissue without any complication.
