ABSTRACT
PURPOSE: To evaluate the effect of adjuvant Mitomycin C (MMC) use on the anatomical and functional success of vitreoretinal surgery (VRS) in severe diabetic tractional retinal detachment (dTRD) patients. METHODS: A retrospective analysis of consecutive patients undergoing VRS due to severe dTRD was conducted. Patients were categorized into those who received 20 µg/0.1 mL MMC via MMC sandwich method (Group 1) and those who did not (Group 2). Demographics, surgical characteristics, visual outcomes, and complications that may related to MMC were analyzed. RESULTS: A total of 25 eyes were included, 13 in Group 1 and 12 in Group 2. No statistical difference was observed in baseline characteristics between the groups. The mean best-corrected visual acuity was 1.90 ± 0.43 logMAR and 1.93 ± 0.41 logMAR preoperatively and 1.60 ± 0.78 logMAR and 1.56 ± 0.78 logMAR postoperatively in Groups 1 and 2, respectively (p = 0.154). The postoperative mean intraocular pressure was 16.23 ± 2.55 mmHg and 13.08 ± 4.94 mmHg in Groups 1 and 2, respectively (p = 0.225). The rate of re-surgery was significantly lower in Group 1 (0% vs. 41.7% in Group 2, p = 0.015). Retina was attached in all patients at the last visit. No MMC-related complication was recorded. CONCLUSION: Intraoperative adjuvant MMC application for severe dTRD significantly reduces re-surgery rates with good anatomical and functional outcomes safely.

BACKGROUND/AIM: To evaluate refractive and strabismic results and the efficacy of intravitreal bevacizumab in retinopathy of prematurity (ROP) ineligible for laser therapy. MATERIALS AND METHODS: Thirty-nine eyes of 20 consecutive infants with high-risk prethreshold ROP (11 infants with Zone I and 9 infants with Zone II disease) who were ineligible for laser therapy due to systemic and/or ocular conditions were treated with intravitreal bevacizumab. Recurrent retinopathy was treated with laser ablation. The final follow-up examination was performed at 29.8 ± 6.0 months of corrected age. RESULTS: All eyes responded to the initial treatment with intravitreal bevacizumab. ROP recurred in 8 eyes (36%) with initial Zone I disease and in only 2 eyes (11%) with initial Zone II disease, which were successfully treated with laser ablation. No eye developed myopia higher than 5.0 diopters. At 2.5 years, the Zone I eyes that had received laser treatment appeared to be more myopic than the Zone I eyes treated only with intravitreal bevacizumab (P = 0.038). A tendency for a higher incidence of strabismus after additional laser therapy was also noted, but was not significant (P = 0.22). CONCLUSION: Avoidance or even deferral of laser ablation with intravitreal bevacizumab may lead to less myopization in ROP compared with conventional laser treatment.
