The study was done to report the surgical outcome and postoperative hypopigmented change around fovea among patients with high myopia who received human amniotic membrane (hAM) graft transplantation for MH.
This retrospective, interventional case series included 10 eyes of 10 consecutive patients with high myopia who received hAM graft to treat persistent or chronic MH with or without retinal detachment in two hospitals. The short-term visual outcomes were analysed.
The preoperative mean (±SD) axial length and MH diameter were 29.9 (±1.8) mm and 881.8 (±438.5) μm, respectively. After hAM transplantation, seven (70%) eyes had complete MH closure and the mean best-corrected visual acuity (BCVA) improved from 1.26 (±0.48) logarithm of minimal angle of resolution (logMAR) before operation to 1.11 (±0.44) logMAR on the last visit (p=0.074). Patchy atrophy-like depigmentation developed around the MH lesion in 40.0% eyes as early as in the first month after surgery.
Parafovea atrophy, a rare complication in the conventional MH surgery, was observed in 40% of eyes with highly myopic MH after hAM graft transplantation. The pathogenesis and long-term consequences need further investigations.
