Retinitis Pigmentosa with Cystoid Macular Edema

40 year old female, presented with central decreasing vision bilaterally. Patient has been diagnosed with Retinitis Pigmentosa since 2003 and has been followed annually by an Ophthalmologist for progression. Upon examination, Cystoid Macular Edema (CME) was found bilaterally. Frame A shows fluorescein angiogram of the right eye and frame B shows fluorescein angiogram of the left eye . Both frames show fluorescein pooling in each eye (Red Arrows), consistent with CME, also consistent with the patients complaint of loss of central vision OU. However, frame E shows severely decreased amplitudes from loss of cone function, which could also be the cause of her decreased central vision. As the only treatable component, she was put on a trial of Diamox 250mg, 1 tab every 8 hours, and Nevanac 1 drop BID to both eyes to treat the CME and to determine if her loss of vision is from CME or poor cone function.
