Evaluation of Optic Nerve Head Perfusion in Unilateral Full-Thickness Idiopathic Macular Hole: An Optical Coherence Tomography Angiography Study

Abstract

Purpose: To investigate the perfusion status of the optic nerve head using optical coherence tomography angiography (OCTA) in patients who had an operation for idiopathic macular hole (IMH) and to compare the differences in the blood flow status of the optic nerve head in both eyes of the patients with unilateral IMH with healthy control eyes. Materials and Methods: The study included patients that underwent surgery with the diagnosis of full-thickness unilateral IMH, with the affected eyes being evaluated as Group 1 and the unaffected eye of the same patients being evaluated as Group 2. A control group (Group 3) was formed with age-matched healthy individuals. In addition to a general ophthalmologic examination, OCTA imaging was performed. Optic disc density and retinal nerve fiber layer (RNFL) measurements were compared between the three groups. Results: The peripapillary and inferior RNFL measurements were lower in Group 1 compared to Group 3 (p
