PurposeThe aim of this study is to report the result of scleral buckling (SB) using a combination of a noncontact wide-angle viewing system and a cannula-based 25 G chandelier endoilluminator.MethodsRetrospective analyses of the medical records of 79 eyes of 79 patients with primary uncomplicated rhegmatogenous retinal detachments who had underwent SB using a combination of a noncontact wide-angle viewing system and a chandelier endoilluminator were performed.ResultsThere were 50 men and 29 women. The mean ± standard deviation age was 43.7±16.0 years. Their preoperative best-corrected visual acuity (BCVA) was 0.31±0.65 logMAR units. The final BCVA was 0.10±0.31 logMAR units, which was significantly better than the preoperative BCVA (P<0.01). The initial and final anatomical success rates were 92.4% and 100%, respectively. Backward logistic multiple regression analysis revealed no relationship between explanatory variables and the primary anatomic success (P=0.104).ConclusionSB using a combination of a noncontact wide-angle viewing system and a chandelier endoilluminator is a modified new technique and may be a valid option for the management of rhegmatogenous retinal detachments.

Aim To compare the anatomic and visual outcomes of 25-gauge (25G), and 27-gauge (27G) transconjunctival sutureless pars plana vitrectomy (TSV) for the management of primary rhegmatogeneous retinal detachment (RRD). Design A retrospective nonrandomized clinical trial. Methods A retrospective comparative analysis of 62 consecutive eyes from 62 patients with 6 months of follow-up was performed. Results Thirty-two patients underwent 25G TSV, and 30 patients underwent 27G TSV for the treatment of primary RRD. There was no significant difference in baseline demographic and preoperative ocular characteristics between the two groups. The initial and final anatomical success rates were 93.8% and 100% in 25G TSV and 96.7% and 100% in 27G TSV, respectively (p=1 and p=1, resp.). Preoperative best-corrected visual acuity (BCVA) (logMAR) was 0.44 ± 0.69 and 0.38 ± 0.61 for 25G and 27G TSV, respectively (p=0.73). The final follow-up BCVA was 0.07 ± 0.25 and −0.02 ± 0.17 for 25G and 27G TSV, respectively (p=0.16). The final BCVA was significantly better than the preoperative BCVA in both groups (p=0.02 and p=0.002, resp.). Preoperative intraocular pressure (IOP) (mmHg) was 13.0 ± 3.5 in 25G TSV and 14.3 ± 2.8 in 27G TSV (p=0.11). IOP did not statistically significantly change in both groups during the follow-up period (p=0.63 and p=0.21, resp.). Conclusion The 27G TSV system is safe and useful for RRD treatment as 25G TSV.

Background: To investigate preoperative clinical factors and visual outcomes of Japanese patients with dysthyroid optic neuropathy (DON) after urgent orbital decompression. Methods: This retrospective, observational case series study investigated 44 patients who exhibited several preoperative clinical factors that might be associated with the need for urgent orbital decompression due to DON. Additionally, the visual acuity of DON patients was compared between the patients preoperatively and at 1 and 6 months postoperatively. Results: All 44 patients received steroid and with or without radiation therapy, with 27 patients able to avoid undergoing urgent surgery. However, the remaining 17 patients required urgent orbital decompression following a lack of response to the therapy. None of the patients who initially avoided surgery required additional surgery for DON. Factors significantly associated with the need for urgent orbital decompression surgery included: female gender, older age, long disease duration, unilateral significant DON, history of resistance to pulsed steroid therapy, unstable thyroid function, high TRAb (Thyrotrophin receptor antibody)value, poor visual acuity, presence of central diplopia, and presence of corneal problems (P < 0.05 each). The results also showed that postoperative visual outcomes of surgery for DON were acceptable. Conclusion: This study revealed several preoperative clinical factors for DON that appear to be associated with the need for urgent orbital decompression surgery in Japanese patients.
