CENTRAL SEROUS RETINOPATHY WITH OPTIC PIT TREATED WITH PHOTOCOAGULATION

In the case described, repeated absence of fluorescence customarily seen with detachment of the pigment epithelium strongly suggests that the mechanism of retinal detachment of the macula occurring with a retinal pit differs from that of central retinal detachment in which there is persistent fluorescence associated with pigment epithelial defects. The absence of fluorescence within the pit or adjacent to the wall of the pit subretinally casts doubt on the primary circulatory origin of the subretinal fluid. These findings, however, are compatible with a vitreal origin of the subretinal fluid, as Sugar3 speculated. In view of the reduction of retinal edema, and of the size of the centrocaecal scotoma, as well as subjective and objective improvement in vision following the use of photocoagulation at the disc margin, these findings appear to represent clinical evidence that the central retinal detachment associated with an optic pit is secondary to an abnormal seepage of fluid, from the pit into the subretinal space (Sugar3-1962). © 1969.
