Enclosed Bays of the Ora Serrata

Abstract

The relationship between enclosed or partially-enclosed ora bays and retinal tears was studied in 1,000 consecutive autopsy eyes. Enclosed ora bay was present in 4.0% and partially-enclosed ora bay in 0.6% of eyes. Retinal tear was associated with 16.7% of either type of ora bay, and occurred posterior to and meridionally aligned with such bays. All such tears occurred at the posterior border of the vitreous base and were a consequence of posterior vitreous detachment. Retinal tears associated with enclosed or partially-enclosed ora bays were present in 0.5% of the 1,000 eyes examined.
