To report the 2-year follow-up surgical outcomes of pathological myopic foveoschisis following 23-gauge vitrectomy in a tertiary referral centre in Taiwan.
This is a retrospective chart review included 20 eyes of 19 patients with pathological myopic foveoschisis. All patients received 23-gauge pars plana vitrectomy with internal limiting membrane (ILM) peeling including the fovea and gas tamponade by one surgeon from November 2011 to January 2017. Best-corrected visual acuity (BCVA) and optical coherence tomographic findings preoperatively and postoperatively were obtained and compared.
Five eyes of foveoschisis with foveal detachment and 15 eyes with pure foveoschisis were enrolled. After more than 2 years follow up, foveoschisis resolved in all cases. The mean BCVA improved from 0.94±0.46 LogMAR to 0.35±0.28 (P<0.05 ). Postoperative central fovea thickness decreased from 612±156 μm to 219±42 μm. No macular hole developed after surgery in all cases.
23-gauge vitrectomy with internal limiting membrane peeling and gas tamponade is effective and safe for pathological myopic foveoschsis. The incidence of postoperative macular hole was lower in the setting of 23-gauge vitrectomy even without the technique of fovea-spared ILM peeling.
