Bilateral macular holes and a new onset vitelliform lesion in Best disease
2017
ABSTRACTBackground: Best vitelliform macular dystrophy (BVMD) is an autosomal dominant hereditary retinal disease caused by BEST1 gene mutations. Macular hole is a rare complication of BVMD. We are the first to report a BVMD case with bilateral macular holes and a new onset vitelliform lesion after a vitrectomy surgery.Materials and methods: A woman with a history of BVMD suffered from a 1-year vision loss in both eyes. Complete ophthalmologic examinations and BEST1 gene screening were performed on the patient.Results: Ophthalmoscopic examinations revealed bilateral macular holes with atrophic photoreceptors and retinal pigment epithelium (RPE). A disease-causing BEST1 mutation N296S (c.887A>G) was detected. A vitrectomy surgery with internal limiting membrane (ILM) peeling and gas tamponade was performed on the right eye. The macular hole closed and maintained stable for 1 year. A new extramacular vitelliform lesion was observed during the follow-up.Conclusions: Macular hole is an unusual but severe comp...
