The management of macular hole retinal detachment and macular retinoschisis in pathological myopia; a UK collaborative study. (November 2018) - Laviers, Heidi
Abstract Purpose To study UK practice patterns for the management of retinal detachment secondary to macular hole (MHRD) and macular retinoschisis (MRS) in pathological myopia (PM). To review the anatomical and visual outcomes of the surgically managed cases. Methods A prospective observational case series for the management of MHRD was undertaken in association with the British Ophthalmological Surveillance Unit (BOSU). The results were combined with retrospective data, collected by the COllaboration of British RetinAl Surgeons (COBRA), on the management of both MHRD and MRS in PM in the UK. A total of 20 cases of MHRD and 53 cases of MRS (27 surgical cases and 26 cases managed conservatively) are reported in this combined study. Results MHRD: Mean baseline best corrected visual acuity (BCVA) was 1.60 logMAR. All cases underwent pars plana vitrectomy (PPV). Mean post-operative BCVA was 1.49 logMAR (p = 0.674). The macular hole was closed in 5/20 (25%) cases, open/flat in 10/20 (50%) cases and open/elevated in 4/20 cases (20%). MRS: Mean baseline BCVA was 0.87 logMAR in the surgical group and 0.45 logMAR in the conservatively managed group (p = 0.002). All eyes that had surgical intervention underwent PPV. Mean post-operative BCVA was 0.68 logMAR (p = 0.183). Anatomical outcomes demonstrated a persistent MRS in 2/27 (7.4%) cases, partial resolution in 7/27 (25.9%) cases and complete resolution in 16/27 (59.2%) cases. Conclusions PPV is the only surgical procedure performed for the management of MHRD and MRS amongst the study participants. Success rates and visual outcomes are limited for MHRD and consistent with the current literature for MRS.
