Abstract: Purpose:To report a case of spontaneous resolution of sub-internal limiting membrane (sub-ILM) fluid associated with an optic disc pit.Case summary: A 13-year-old girl presented with micropsia in her right eye that had onset 3 days prior upon rising from a lying position. Her best-corrected visual acuity (BCVA) was 20/25. Fundus examination revealed an optic disc pit, and optical coherence tomography showed sub-ILM fluid, perifoveal macular traction, and retinoschisis. Over a six-month observation period, the sub-ILM fluid, macular traction, and retinoschisis resolved spontaneously, and BCVA improved to 20/20 with no recurrence.
Conclusions:In this pediatric case, sub-ILM fluid associated with an optic disc pit resolved spontaneously. The course of this condition in children may differ from that in adults due to the greater elasticity of the ILM in the pediatric retina. The presence of cystic sub-ILM fluid with surrounding macular traction suggests that the fluid entered between the ILM and retinal nerve fiber layer via the optic disc pit, likely from the subarachnoid space.
