Abstract
Background
The pathogenesis of optic disc pit maculopathy is still unknown, although recent optical coherence tomographic (OCT) analyses have made a great contribution to clarifying its morphological appearance. The best treatment for this disease is also controversial.
Case
We report on a 7-year-old girl with optic disc pit maculopathy associated with a separation of the internal limiting membrane (ILM) near the optic disc.
Observations
The OCT images before treatment showed a conduit from the perineural space to the schisislike separation of the sensory retina with a dome-shaped separation of the ILM. A serous detachment (SD) in the macula, centered on the fovea, was also present. In OCT images after laser photocoagulation, the conduit appeared to be closed, but the SD was still present. Vitrectomy with ILM removal and gas tamponade resulted in a marked reduction of the SD in the macular area. Focal macular electroretinograms and visual acuity demonstrated a recovery of macular function.
Conclusion
The dome-shaped separation of the ILM suggested that the vitreous might be exerting a tractional force on the optic disc pit, and vitrectomy with ILM peeling released the traction on the optic disc pit. Jpn J Ophthalmol 2005;49:411–413 © Japanese Ophthalmological Society 2005
