Abstract
A surgical approach for the drainage of fluid leaking over the pit in optic disc pit maculopathy is described, and a theory of the origin of fluid is discussed. In two cases, complete fluid-air exchange was performed. The air infusion pressure was decreased to 5 mm Hg, and the collected fluid was drained by raising the infusion pressure to 25 mm Hg. The fluid inside the back-flush needle was routed via a microcentrifuge tube. Biochemical analyses of the fluids were conducted in order to find their origin. Results of the first and second case were comparable to normal cerebrospinal fluid (CSF) levels (chloride: 125 mmol/L, 122 mmol/L; sodium: 146 mmol/L, 147 mmol/L; potassium: 2.8 mmol/L, 3.0 mmol/L; protein: 29 mg/dL, 18.4 mg/dL; and glucose: 60 mg/dL, 57 mg/dL, respectively). These findings suggest that the origin of subretinal fluid found in the submacular space in optic disc pit maculopathy is CSF.
