Abstract
The appropriate surgical technique to improve the closure rate of perioperative full-thickness macular hole (FTMH) secondary to submacular hemorrhage (SMH) with sub-internal limiting membrane (ILM) hemorrhage caused by retinal arterial macroaneurysm (RAM) rupture remains an unsolved clinical problem. Several ILM transplantation techniques have been attempted, but these are challenging. Our new technique can remove sub-ILM hemorrhage with the central fovea ILM intact, without peeling the ILM. The medical records of three eyes from three patients with SMH and sub-ILM hemorrhage secondary to RAM rupture were retrospectively reviewed. During the surgery, a small ILM fissure was made outside the central fovea with ILM forceps, and sub-ILM hemorrhage was washed out through it by manually spraying balanced salt solution. Sub-ILM hemorrhage removal was achieved successfully in all eyes, with no occurrences of FTMH or other complications. Best-corrected decimal visual acuity improved from 0.05 (Snellen equivalent (SE), 20/400), 0.05 (SE, 20/400), and 0.05 (SE, 20/400) preoperatively to 0.3 (SE, 20/63), 0.4 (SE, 20/50), and 0.15 (SE, 20/125) at 3 months postoperatively, respectively. This new technique may help keep the foveal ILM intact and prevent perioperative FTMH formation.
