Drainage of subretinal fluid in optic disc pit maculopathy using subretinal 42-gauge cannula: a new surgical approach

Different surgical approaches have been used for the treatment of optic disc pit associated maculopathy, with increasing emphasis on vitrectomy. Case report We report a case of optic disc pit maculopathy where vitrectomy was combined with subretinal fluid drainage using a 42-gauge subretinal cannula connected to a "back-flush" flute handle. No retinopexy was performed at the site of drainage. This technique resulted in almost complete resolution of subretinal fluid by 6 weeks, with visual acuity improving from 1.00 Log MAR preoperatively to 0.40 at 8 months after surgery. We describe a novel technique for subretinal fluid drainage using a subretinal 42-G cannula connected to a standard "back flush" flute in optic disc pit-associated maculopathy.
