Vitrektomize Gözlerde Pars Plana İnfüzyon Destekli Penetran Keratoplasti: Tanımlayıcı Araştırma

Abstract

Objective: To present the cases with a history of vitrectomy, that underwent penetrating keratoplasty (PKP) combined with pars plana infusion in a closed. Material and Methods: The medical records and surgical videos of the patients, with a history of pars plana vitrectomy (PPV), who underwent PKP were reviewed retrospectively. Demographic data, including age at the time of the PKP, gender; indication for the PPV, the time between PPV and PKP, indication for PKP, best-corrected visual acuity (BCVA, LogMAR), lens status and additional ocular diseases preoperatively; intraoperative complications and BCVA, graft status and complications postoperatively were recorded. Results: PKP with manually assisted pars plana infusion was performed in 16 vitrectomized eyes of 16 (7 female and 9 males) patients in this study. Silicone oil extraction was performed in 7 (43.7%) patients (anteriorly in 4, posteriorly in 3). The mean BCVA was improved statistically significantly at the last follow-up visit (2.23±0.3 vs 1.93±0.7, LogMAR, p=0.040). Optic atrophy was found in 11 (68.7%) patients. Choroidal detachment occurred in the early postoperative stage in 1 (6.2%) patient and managed with oral steroids. Graft rejection was seen in 6 (37.5%) patients. Four (25%) patients underwent repeated PKP and 2 (12.5%) patients were listed on the transplant list. At the last follow-up visit, 11 (68.7%) grafts were clear and 5 (31.2%) were edematous. Conclusion: PKP in vitrectomized eyes, pars plana infusion is a cheap and effective method that may prevent hypotony in these patients and the procedure may result in good visual outcomes where no additional retinal problems are accompanied.
