To compare surgical outcomes between subretinal fluid drainage through the macular hole (MH) and through sites other than the MH during vitrectomy for MH retinal detachment in highly myopic eyes.
Retrospective analysis was performed on the medical records of 41 patients who underwent vitrectomy for MH retinal detachment in highly myopic eyes. Group M included eyes in which subretinal fluid was drained through MH. Group E included eyes in which subretinal fluid was drained through an extramacular break or retinotomy. Pre- and postoperative visual acuity, reattachment rate, and MH closure rate were investigated.
Primary retinal reattachment was achieved in 13 of 21 eyes (62%) in Group M and in 19 of 20 eyes (95%) in Group E (P = 0.020). The MH was closed more frequently in Group E (15 eyes) than in Group M (7 eyes; P = 0.012). Ambulatory vision of 20/400 or better was achieved in 16 eyes in Group E and in 10 eyes in Group M (P = 0.033).
Extramacular drainage of subretinal fluid resulted in better outcomes than the conventional procedure of drainage through the MH.
Drainage of subretinal fluid through sites other than the macular hole resulted in better functional and anatomical outcomes than the conventional drainage procedure through the macular hole during vitrectomy for macular hole retinal detachment in highly myopic eyes.
