Spontaneous macular hole closure possible after vitrectomy
In most cases, after vitrectomy anteroposterior vitreofoveal traction associated with macular hole formation does not apply. However, tensile and degenerative forces may lead to hole remodeling, according to a case study.
Wayne R. Lo, MD, and G. Baker Hubbard, MD, described the case of a 69-year-old woman who had a vitrectomy for vitreous hemorrhage seven years earlier. She presented with decreased visual acuity and a macular hole that spontaneously resolved within 4 months. One year after that, the hole re-opened. Visual acuity returned after an internal limiting membrane peel.
Initially, optical coherence tomography showed a macular hole with perifoveal cystoid degeneration and bridging elements. At follow-up visits, OCT showed resolution of the cystoid degeneration.
The case report is published in the May issue of American Journal of Ophthalmology.
