Acute retinal detachment after Nd:YAG treatment for vitreous floaters and postertior capsule opacification: a case report

Modern laser surgery uses Nd:YAG laser capsulotomy for posterior capsule opacification (PCO) and Nd:YAG laser vitreolysis for symptomatic vitreous floaters (VF). We report a case of acute retinal detachment seven days after Nd:YAG laser capsulotomy combined with Nd:YAG laser vitreolysis and analyze the cause of this complication.

A 58-year-old myopic woman complained of decreased visual acuity and symptomatic floaters with her left eye for 3 months. We found she had significant PCO and VF in the posterior vitreous. She underwent neodymium-doped yttrium aluminum (Nd:YAG) laser vitreolysis immediately after Nd:YAG capsulotomy. After 7 days, she complained of rapid vision decline and dark shadows in her treated eye. We found she had a acute severe rhegmentogenous retinal detachment (RD) involving the macula. Then she underwent vitrectomy, retinal reattchment and silicone oil tamponade surgery immediately. Six months later, silicone oil was removed and the best corrected visual acuity (BCVA) of her left eye gradually improved to 10/20 and maintained during a 1-year follow-up period.

As myopic patients are at risk of developing retinal detachment, Nd:YAG vitreolysis and capsulotomy should be performed with caution. The laser energy should be as low as possible and careful focus is necessary to reduce interference to the retina.
