Staged lensectomy and vitrectomy in the management of stage 5C retinopathy of prematurity with corneal opacification: long-term follow up

Abstract

AIM: To verify the feasibility and safety of staged lensectomy and vitrectomy in stage 5C retinopathy of prematurity (ROP) with corneal opacification. METHODS: This was a retrospective, interventional, consecutive case series. Twenty-two eyes of 18 stage 5C ROP patients with corneal opacification were included. Regular combined lensectomy and vitrectomy were not prescribed due to the invisible fundus. Staged lensectomy and posterior vitrectomy were performed. The anatomical and visual outcomes were reviewed at the final follow-up visit. RESULTS: The mean gestational age of ROP patients was 29.3±1.6wk (range: 27-32wk), comprising 8 males and 10 females. The average birth weight was 1363.0±300.0 g. All the eyes had corneal opacity and flat or disappeared anterior chambers pre-operatively. Two eyes had complicated cataract and 7 eyes had retrolental fibroplasia. Six eyes had posterior pupillary synechiae or membranes. Seven (31.8%) eyes had vascularly active retinas. The average interval between two procedures was 6.8±4.6mo (2.5-18.5mo). After surgeries, all the patients had normal anterior chambers. Fourteen eyes had clear corneas. The intraocular pressure of 3 eyes with glaucoma was controlled by medication. Two eyes had ocular phthisis. The retina was reattached in 3 eyes and partially attached in 11 eyes. Visual acuity ranged from no light perception to hand motion. CONCLUSION: Staged lensectomy and vitrectomy are procedures that can halt progression to further complications and preserve some useful eyesight in stage 5C ROP patients with corneal opacification. The earlier the lensectomy is performed, the better the prognosis is.
