Optic Pit Maculopathy: Adjunctive Treatment Using Oral Spironolactone and Topical Dorzolamide

PURPOSE: There is no consensus for the treatment of optic disc pit maculopathy (ODPM). We describe a case of ODPM refractory to vitrectomy that was successfully treated with systemic spironolactone and topical dorzolamide 2%. METHODS: Case report. RESULTS: A 27-year-old male was referred for decreased vision in the right eye secondary to macular edema. Fundus examination and optical coherence tomography imaging revealed an optic pit maculopathy with significant macular schisis and intraretinal fluid. After an initial observation period, we performed pars plana vitrectomy with internal limiting membrane peeling, fibrin glue, and gas endotamponade. At the 2 months postoperative follow-up, anatomic and functional outcomes remained unimproved. Oral spironolactone and topical dorzolamide 2% were, therefore, added. Significant reduction in the intraretinal fluid and macular schisis was demonstrated at the last follow-up 2 years postoperative. CONCLUSION: The mechanisms underlying optic disc pit maculopathy remain controversial, and treatment guidelines are unclear. To our knowledge, this is the first description of an OPDM treated with a combination systemic mineralocorticoid receptor antagonist and topical carbonic anhydrase inhibitor as adjuvant therapy to vitrectomy with favorable outcomes. We also review the literature and propose mechanisms through which these treatment entities may act.
