Recurrent Retinal Detachment
The main question when examining the retina of a recurrent detachment is: Where is the hole? If a new hole is present, we would operate the eye as a primary detachment. But in many cases, a retinal break cannot be found. In this case a minihole must be searched for. This minihole is often a laser necrosis and located at the edge of a laser scars. In order to localize the hole, you must remember the Lincoff rules and use the following trick: Inject PFCL posterior to the suspected hole and look for Schlieren. Schlieren is subretinal fluid which enters the vitreous cavity through the hole. Search for the hole using a light fiber and scleral depressor.
