Microperimetry evidence of functional improvement after vitrectomy for optic disc pit-related intraretinal fluid without serous detachment

摘要

Congenital optic disc pit (ODP) occurs at a rate of 1:11000 and causes macular pathology in 25-75%. Spectral domain optical coherence tomography (SDOCT) studies demonstrated that fluid arising from an ODP can go directly to the sub-retinal space and the various layers of the neurosensory retina including the sub-internal limiting membrane (sub-ILM) space. Although it is known that sub-retinal fluid leads to visual loss, the impact of intraretinal fluid - so-called retinoschisis, on retinal function has not been studied in detail. We report the microperimetry and SDOCT findings from a case of ODP with extensive intraretinal fluid without serous retinal detachment, pre- and post-vitrectomy, to correlate functional improvement with anatomical recovery.
