Case report of a 65 year old female patient who sustained accidental frequency doubled Nd: YAG laser foveal burn while undergoing left eye panretinal photocoagulation(PRP) for diabetic retinopathy is presented with subsequent 4 years follow-up. Upon initial evaluation, the best-corrected visual acuity of affected eye was count finger at 1 foot (CF 1’) or 20/8000 OS.
Immediate Fundoscopic examination revealed foveal laser burn. Corticosteroids, in the form of 40 mg prednisolone, were administered orally for two weeks followed by 10 mg per week taper alongwith long term topical Nepafenac three times a day. Fifteen days following exposure, fundoscopic examination revealed a distinct epiretinal membrane.
The best corrected visual acuity of the affected eye improved to 20/80 OS over a period of four years. This clinical course is different to those of previously reported cases of foveal laser burn in which visual acuity did not recover despite spontaneous regression of the epiretinal membrane.
