A case of accidental macular injury by Nd: YAG laser and subsequent 6 year follow-up.
Here, we report the case of a patient who sustained Nd: YAG laser macular injury with subsequent 6 year follow-up evaluation. A 23-year-old female was accidentally exposed to a Q-switched Nd: YAG laser without protective goggles. Upon initial evaluation, the best-corrected visual acuity of her affected eye was 20/100 OD. Fundoscopic examination revealed a macular laser burn and vitreous hemorrhage. Corticosteroids, in the form of 60 mg prednisolone, were administered orally with a 10 mg per week taper. Nineteen days following exposure, fundoscopic examination revealed a distinct epiretinal membrane which resolved within six months. The best-corrected visual acuity of the affected eye remained 20/100 OD. This clinical course is similar to those of previously reported cases including vitreous hemorrhage and subsequent epiretinal membrane formation. However, visual acuity did not recover despite spontaneous regression of the epiretinal membrane and at 6 year follow-up, there was neither choroidal neovascularization nor macular hole formation.
