Macular hole formation associated with idiopathic parafoveal telangiectasia

Background: To report the occurrence of a full thickness macular hole in association with idiopathic parafoveal telangiectasia. Methods: Observational case report. Results: A 60-year-old female with a history of bilateral idiopathic parafoveal telangiectasia presented with acute complaints of decreased vision and metamorphopsia in her right eye. The patient's retinal examination was significant for idiopathic parafoveal telangiectasia bilaterally, and a new, full-thickness macular hole in the right eye which was confirmed by optical coherence tomography. Conclusions: Full-thickness macular hole formation may occur in conjunction with idiopathic parafoveal telangiectasia, which has not been reported to date. Idiopathic parafoveal telangiectasia, IPT, is a clinical entity with distinct biomicroscopic and fluorescein angiographic findings [4], which may be divided into developmental and acquired forms [5]. Idiopathic macular hole formation is a relatively common condition, which tends to occur more frequently in females in their 7th and 8th decades of life [2]. Idiopathic parafoveal telangiectasia has been reported in association with lamellar macular holes [8], but, to our knowledge, not with a full-thickness macular hole. Herein we report the case of a patient with bilateral idiopathic parafoveal telangiectasia who developed a full-thickness macular hole.
