Evaluation of Topical Mitomycin-C Eye Drops After Reconstructive Surgery for Anophthalmic Contracted Socket.

Abstract

PurposeTo report the outcomes of using topical mitomycin-C (MMC) after reconstructive surgery for contracted socket and to compare the results with those of the conventional postoperative treatment.Patients and MethodsThe medical records of patients who underwent reconstructive surgery for contracted anophthalmic socket were retrospectively reviewed. Based on the postoperative treatment protocol, two groups of patients were identified; group I (15 patients) who received topical MMC drops (0.02%) 4 times daily for 6 weeks and group II (15 patients) who received the conventional treatment (topical antibiotic-steroid combination). Preoperative data were extracted for age, gender, cause and timing of anophthalmia, history of previous surgeries, preoperative forniceal depth and socket volume (SV). The main postoperative outcome measures were superior fornix depth (SFD), inferior fornix depth (IFD) and SV at the end of 6th postoperative month. Prosthesis fitting and complications were also considered for analysis.ResultsThe mean preoperative IFD was 1.67±0.04 mm in group I and 1.58±0.37 mm in group II, by the end of the 6th postoperative month it increased to 6.1 ±0.27 mm and 5.12 ±0.25mm, respectively. The mean preoperative SFD in group I was 8.3±0.9 mm and 8.9±1.1 mm in group II, by the end of the 6th postoperative month SFD became 13.4±1.2 mm and 10.2±1.4 mm in groups I and II, respectively. The mean SV measured six months postoperatively was 1.9±0.2 mL and 1.3±0.09 mL in groups I and II, respectively. These differences in the postoperative SFD, IFD and SV between both groups were statistically significant. More cases reported successful fitting in group I than in group II but this difference was not statistically significant.ConclusionPostoperative use of topical MMC is associated with higher forniceal depth and greater SV when compared to the conventional treatment in socket reconstructive surgeries with amniotic membrane graft (AMG).
