The Ætiology and Treatment of Retinal Detachment

Prevailing opinion still appears to be with Gonin who has taught that a hole or tear in the retina is the cause of detachment and that to cure this detachment it is all-important to localize the hole and occlude it by some means or other. If the operation is not successful in closing the hole or tear, the detachment recurs. His theory is however disputed by many, notwithstanding the fact that the principles underlying his method of cure have been generally admitted. Shapland classifies holes and tears into five groups as follows :? 1. Round, oval, fenestrated, punched-out holes.
