    Abstract:
    BACKGROUND: Optic disc pits frequently lead to visual deterioration due to macular retinoschisis or serous retinal detachment. Here, we report a case of optic disc pit-associated macular retinoschisis due to intraretinal fluid accumulation that resolved with improvement in visual acuity after treatment with topical dorzolamide. CASE DESCRIPTION: A 56-year-old otherwise healthy female with no ocular history presented with 2 weeks of slowly worsening blurry vision in her right eye. Visual acuity was 20/30 in the right eye. Posterior segment examination revealed posterior vitreous detachment, an optic disc pit at 9 o'clock, macular edema and foveoschisis with fluid extending from the optic nerve, and a normal peripheral retina. Optical coherence tomography imaging of the macula showed central subfield thickness of 526 µm. The patient preferred no surgical intervention, so topical dorzolamide 2% three times daily was initiated. Over the next 2 years, the central subfield thickness steadily declined from 526 to 262 µm, and her vision improved to 20/20 with improvement in the macular retinoschisis. CONCLUSION: Our report presents a case of resolution of optic disc pit-associated macular retinoschisis due to intraretinal fluid accumulation with possible role for dorzolamide as a potential treatment option.
