Abstract

Aim: To assess corneal endothelium changes by non-contact specular microscopy in eyes underwent pars plana vitrectomy (PPV) with temporary silicone oil (SO) tamponade with or without phacoemulsification. Methods: We concluded 24 patients, divided to two groups: 12 patients had pars plana vitrectomy with SO injection (group 1) and 12 patients had combined phaco-vitrectomy with SO injection (group 2). All of them underwent full ophthalmological examination: best corrected visual acuity (BCVA), measurement of IOP, fundus examination and specular microscopy follow ups at the 1^st week, 1^st month and 3^rd month visits. Results: The count of Endothelial cell density (ECD) in group 1 dropped from 2543.58 ± 759.62 cell/mm², to 2299.33 ± 729.87 cell/mm², while in group 2 was 2621.08 ± 514.50, dropped to 2307.50 ± 575.55 respectively, and the mean cell density (MCD) decreased significantly in group 1 and group 2, at 3rd month than at 1st week. Three months after operation, CV (polymegathism) was 34.58 ± 4.29% and 35.75 ± 4.16%, hexagonality (pleomorphism) was 46.83 ± 8.67% and 47.83 ± 10.50%, while mean CCT was 553.08 ± 22.13 μm and 548.17 ± 33.12 for group 1 and 2 respectively, and without corneal edema reported at the study end. Conclusion: pleomorphism (decreased HEX), polymegathism (increased CV) and endothelial cell (EC) loss were documented in all patients underwent pars plana vitrectomy (PPV) with silicone oil (SO) injection with a higher probability of polymegathism (CV increase) noted after adding phacoemulsification to the procedure. These findings strongly suggest early SO removal after reaching aimed tamponading action to avoid SO keratopathy.
