Retinal redetachment involving a macular hole resulting from hypotony after trabeculectomy in a highly myopic eye.

A 57-year-old woman with high myopia underwent trabeculectomy 21 months after a successful vitrectomy with peeling of the internal limiting membrane to treat a bullous retinal detachment associated with a macular hole. A shallow retinal detachment involving the macular hole developed on the sixth postoperative day after a 3-day period of hypotony. This case was unique because recurrence of the retinal detachment involving a macular hole in a highly myopic eye occurred in association with hypotony after glaucoma filtering surgery, with the retinal detachment resolving spontaneously following normalization of intraocular pressure even though the macular hole remained open.
