Clinical Summary

Slit-lamp biomicroscopy (D) of the left eye, with a visual acuity of 20/200, also showed scattered dot and blot hemorrhages throughout the posterior pole-

Optical Coherence Tomography

OCT: (E) demonstrated macular thickening and reduced optical reflectivitv consistent with serous fluid accumulation, The retinal thickness measured directly in the fovea was 280 ¬°iitl The patient elected to receive focal argon laser photocoagulation treatment in this eye. Four months later, a follow-up OCT (F) scan showed significantly decreased retinal thickening and increased optical reflectivity from within the neurosensory retina. The central fovea 1 thickness had decreased to 140 pni The visual acuity in this eye, however, had not improved.
