A case of Nd:YAG laser-induced traumatic macular hole with good visual prognosis after vitrectomy with inverted internal limiting membrane technique.

ABSTRACT

PURPOSE: To report an accidental case of traumatic macular hole caused by NdYAG laser in a dermatology clinic. OBSERVATIONS A 24-year-old woman sustained a laser injury to her right eye while practicing a dermatologic treatment using a NdYAG laser without wearing protective goggles. She noticed sudden-onset and progressing visual loss in her right eye and consulted an ophthalmologist 2 days after injury. The best-corrected visual acuity (BCVA) of her right eye decreased to 20/133. Fundus examination showed white parafoveal flecks with a central retinal hemorrhage and underlying serous retinal detachment. The retinal sensitivity in this lesion deteriorated. Two weeks later, a full-thickness macular hole (FTMH) developed in the affected eye. She was referred to Nagoya City University Hospital where the laser damage described was observed. The BCVA was 20/67. She underwent pars plana vitrectomy performed using the inverted internal limiting membrane (ILM) flap technique and gas tamponade. One week postoperatively, the FTMH closed, the BCVA in her right eye improved to 20/50, and the retinal sensitivity in the macular area mostly improved. The BCVA gradually improved and reached 20/25 9 months after the injury. CONCLUSIONS AND IMPORTANCE Protective goggles must be worn when using an NdYAG laser in the laboratory or clinical setting. In the unfortunate event of a FTMH, early vitrectomy with an inverted ILM flap technique can be helpful to achieve a good visual prognosis.
