METHODS: An anonymous online survey was completed by 117 YOs in the Asia-Pacific regarding their RRD surgery experiences in 2021-2022.
RESULTS: To achieve a 90% probability of surgical competency, 91 vitrectomy and 34 scleral buckling (SB) completions during fellowship were needed. In total, 49 (41.9%) YOs had fellowship affected by COVID-19. In the COVID versus pre-COVID era, however, the volume of SB completions per fellowship year decreased significantly (median [IQR] 3.3 [1.5, 9] vs. 13 [6.5, 23]; p
METHODS: A retrospective case series of eyes with myopic foveoschisis that underwent vitrectomy and PAIR. Visual acuity, fundus photographs, and optical coherence tomography measurements were obtained and analyzed. Data are presented as medians (ranges).
RESULTS: A total of seven eyes underwent PAIR and were followed up for 339 days (188-436 days). No intraoperative complications were noted. One eye exhibited postoperative macular hole formation, but the hole was healed through fluid-gas exchange. At the last follow-up, the visual acuity had improved from 20/66 (20/332-20/40) to 20/40 (20/100-20/25), and the central foveal thickness had decreased from 576 µ m to 269 µ m. A repositioned internal limiting membrane (ILM) was observed in six of the eyes, and inner retinal dimples were noted in only two eyes. However, retinal wrinkles under the repositioned or perifoveal ILM were noted in five eyes.
CONCLUSION: The PAIR technique relieved traction, restored the ILM, and achieved functional and morphological improvement in eyes with myopic foveoschisis. Limited occurrence of inner retinal dimples and retinal thinning was noted, but retinal wrinkles occurred, likely due to ILM contracture.
METHOD: This is prospective and randomized clinical trial. Our study population included 30 eyes undergoing pars plana vitrectomy that required near total corneal debridement intra-operatively for surgical view. We compared the residual wound and wound healing rate in between 3 groups: 10 diabetic eyes (DMV) on topical SH 0.18%; 10 diabetic eyes (DMC) and 10 non-diabetic eyes (NDM) not treated with topical SH 0.18%. The corneal epithelial wound was measured at 12, 24, 36, 48, 60, 72 and 120 h after the vitrectomy surgery.
RESULTS: DMC group had corneal wounds that reepithelialization significantly more slowly than in NDM and DMV groups at 12, 24, 36 and 48 h (Mann-Whitney test p
DESIGN: Retrospective interventional case series.
METHODS: Thirty-nine eyes from 39 patients with a FTMH <600 μm were included from a single institution. All patients underwent vitrectomy using a semicircular single-layered ILM inverted flap assisted by a sub-perfluorocarbon liquid injection of ophthalmic viscoelastic device (OVD) technique. Best-corrected visual acuity (BCVA) and spectral domain optical coherence tomography were used to compare outcomes between nasal (n = 19) and temporal (n = 20) groups.
RESULTS: At 6 months postoperatively, all FTMHs closed and BCVA were significantly improved. Overall, 36 eyes (92%) achieved U-shaped closure, and ellipsoid zone restoration was noted in 24 eyes (62%). An ILM flap was present in 29 eyes (74%) and 86% remained single-layered. There were significantly more deep inner retinal dimples in the temporal group (35%) compared with 5% in the nasal group (P = .04), but these were unrelated to BCVA. Significant retinal thinning in the temporal outer sub-field was noted in the temporal group and was negatively correlated with BCVA (rho [ρ]: - .53; P = .03). No significant postoperative retinal displacement was noted in either group.
CONCLUSIONS: The technique of using sub-perfluorocarbon liquid injection of OVD secured single-layered flaps intraoperatively and postoperatively. Both the nasal and temporal inverted ILM flaps repaired FTMH and improved visual acuity. However, both temporal macular thinning and deep inner retinal dimples were significantly greater in the temporal group.
METHODS: Thirty-five cases of highly myopic eyes with MHRD in 35 patients who underwent an initially successful vitrectomy with macular plug and were followed up for at least 3 years were reviewed. The anatomical outcomes were evaluated by fundus examination, fundus photographs and optical coherence tomography (OCT). Myopic features after the surgery were differentiated according to recommendations of the Meta-analysis of Pathologic Myopia (META-PM) Study Group. The best-corrected visual acuities (BCVAs) before and after surgery were analysed as the functional outcome. Main outcome measures time-course changes in BCVA and complications.
RESULTS: The mean patient age was 61.0 ± 11.4 years. The follow-up was 45.2 ± 8.6 months (ranged from 36 to 71 months). The mean axial length was 29.3 ± 1.2 mm. All eyes demonstrated attached retina, but 2 eyes (5.7%) developed reopened macular holes until the last follow-up. Complications of postoperative rhegmatogenous retinal detachment were detected in 2 eyes (5.7%) within 1 year and retina reattached after the secondary vitrectomy. Three cases (8.6%) of prolonged subretinal fluid lasting more than 1 year were detected but finally absorbed completely. Comparing 1-3 years postoperatively, myopic features showed significant progression of myopic maculopathy category (p = 0.035). Functionally, significantly improved BCVA could be maintained postoperatively between 6 months and 3 years. However, vision of 14 eyes (40.0%) worsened within 1-3 years postoperatively, and visual deterioration was associated with progression of myopic maculopathy (p = 0.004) and pre-existing disease of glaucoma (p = 0.006).
CONCLUSIONS: A vitrectomy combined with macular plug provided favourable outcomes in the long term, over the ≥3-year follow-up period.
