Purpose: To evaluate long-term clinical results of 2 different accelerated corneal crosslinking (CXL) protocols in pediatric patients with keratoconus. Setting: Beyoğlu Eye Training and Research Hospital, Istanbul, Turkey. Design: Retrospective case-control study. Methods: Patients who were younger than 18 years were included in the study. Group 1 received 4 minutes of illumination at 30 mW/cm2, and Group 2 received 5 minutes of illumination at 18 mW/cm2. Uncorrected and corrected distance visual acuities, manifest refraction, corneal topographic parameters, and corneal higher-order aberrations (HOAs) were evaluated at baseline and during 1-, 3-, and 5-year follow-up visits. Results: A total of 143 eyes from 86 patients were included in the study. There were 30 eyes in Group 1 and 113 eyes in Group 2. The mean follow-up time was 4.15 ± 0.99 years. Mean keratometry (K) and/or maximum K progressed ≥1.00 diopter (D) in 7 eyes (23.3%) in Group 1 and 19 eyes (16.8%) in Group 2 (P = .411). Mean K and/or maximum K decreased ≥2.00 D in 2 eyes (6.7%) in Group 1 and 24 eyes (21.2%) in Group 2 (P = .06). In Group 1, there were no statistically significant differences in topographic parameters during follow-up. In Group 2, there was a statistically significant reduction in total HOA and coma during the 5-year visit when compared with the preoperative visit (P = .005 and P = .045, respectively). Conclusions: Accelerated CXL is beneficial in terms of halting the progression of keratoconus in pediatric patients throughout 5 years of follow-up examinations. An increased irradiance with a reduced application time reduces the topographic effects of CXL.

Subtotal vitrectomy seems as an effective and safe surgical technique in the treatment of macular diseases.

In conclusion, IVAfl treatment seemed to be effective in patients with ME secondary to RVO with respect to visual and anatomical outcomes in real life. In this study the number of visits and injections was lower that randomized controlled trials, but the functional and anatomical outcomes are probably still acceptable.

Overall stone-free rates after SWL treatment was found to be significantly lower in patients with the history of ORSS than in patients without, and this finding was significantly prominent for lower calix stones. We believe that retrograde intrarenal surgery or mini- /micro-percutaneous nephrolithotripsy, despite its possible difficulties in accessing due to anatomical changes, might be a good alternative for SWL.

PurposeTo assess the outcomes of subtotal vitrectomy in idiopathic macular hole (IMH).MethodsThe patients with idiopathic IMH who had undergone vitreoretinal surgery and followed up for at least 12 months post-operatively were included. First the posterior hyaloid was detached, then cortical vitreous was removed incompletely by leaving anterior vitreous intact. Internal limiting membrane was peeled with the aid of brilliant blue. A non-expanding volume of perfluoropropane was used as a tamponade and face-down positioning for 5 days was suggested to the patients. The main outcome measure was the closure rate of IMH.ResultsForty-three eyes were included. The mean follow-up time was 15.0 ± 3.8 months after surgery. Single surgery anatomical success was 86.0%. The mean BCVA at baseline, month 1, 3, 6, 12 and at the last follow-up was 0.99 ± 0.33 LogMAR (0,5–1.80), 1.04 ± 0.33 LogMAR (0.5–1.8), 0.94 ± 0.46 LogMAR (0.3–3.0), 0.84 ± 0.33 LogMAR (0.3–1.5), 0.82 ± 0.35 (0.2–1.5), and 0.70 ± 0.34 (0.1–1.5) (p > 0.05, for all). The mean visual acuity increased by 2.9 lines at the last follow-up visit and 51.2% of the patients gained ≥ 3 lines of vision.ConclusionThe results of this study indicated limited core vitrectomy as a safe and effective surgical technique in the treatment of IMH, resulting in acceptable functional and anatomical outcomes without significant intra- and post-operative complications.
