Oral acetazolamide as a medical adjuvant to retinal surgery in optic disc pit maculopathy in a pediatric patient.

PURPOSE

To describe a novel combination of surgical and medical management for the treatment of optic disc pit maculopathy.

OBSERVATIONS

A 12-year-old obese girl with bilateral optic disc pits presented with decreased vision in the left eye (20/400). On dilated fundus examination, she was found to have a macula-involving serous retinal detachment. Pars plana vitrectomy, posterior hyaloid peel, internal limiting membrane peel, fluid-air exchange, temporal juxtapapillary endolaser, and CF tamponade were performed. Postoperatively, there was persistence of subretinal fluid, so oral acetazolamide and a weight loss regimen were started. After 3 months of medical treatment, the subretinal fluid decreased significantly and visual acuity improved to 20/60.

CONCLUSION AND IMPORTANCE

Currently, the mechanisms leading to optic disc pit maculopathy remain a topic of debate. As optic disc pits may provide a conduit between the subarachnoid and subretinal spaces, the reduction of intracranial pressure with the use of systemic carbonic anhydrase inhibitors may play a role in decreasing the subretinal fluid associated with select cases of optic disc pit maculopathy.
