Proliferative Diabetic Retinopathy with Serous Macular Detachment

These OCT scans are from a 41 year old male patient who developed a case of serous macular detachment following a heavy single-session laser panretinal photocoagulation (PRP) treatment of the right eye. The initial scans were taken a week apart. The intensity of the PRP can cause choroidal exudation with breakdown of the outer blood-retina barrier and collection of subretinal fluid (yellow arrows). The patient complained of dimming of vision. No treatment besides explanation is needed as the fluid spontaneously resolves, which can be seen in the 1-month follow-up. It appears that there was residual damage to the ellipsoid zone (turquoise arrows).
