Background:
To characterize the resolution pattern and macular structure recovery of optic disc pit-maculopathy (ODP-M) following vitrectomy using spectral domain-optical coherence tomography (SD-OCT).
Methods:
This is a single-center, retrospective, observational case series. Serial SD-OCT scans of all consecutive eyes of ODP-M undergoing vitrectomy were evaluated to analyze the sequence of maculopathy resolution.
Results:
Subretinal fluid (SRF) resolved/reduced in 9 of 12 eyes over a mean of 6 months. For eyes showing resolution, we observed that the closure of the communication tract (CT) [1-3 months] preceded the closure of outer layer defect (OLD) [2-6 months], while SRF[1-12 months] and outer retinal fluid(ORF)[1-12 months] were the last to be resolved. Three eyes with residual SRF/macular fluid had a patent CT.
Conclusion:
Maculopathy resolved in a staged manner: closure of CT preceded the closure of OLD and absorption of SRF. Non-closure of CT was associated with the persistence of maculopathy.
Synopsis:
Optic disc pit maculopathy following vitrectomy shows a staged resolution. The persistence of maculopathy is seen in eyes with non-closure of the communication tract.
