Pattern of perception of Haidinger brushes by patients with unilateral idiopathic macular hole

Purpose: To report the pattern of perception of Haidinger brushes by patients with unilateral idiopathic macular hole before and after surgery. Cases: This study was made on 20 patients with unilateral idiopathic macular hole. The series comprised 6 males and 14 females. The age ranged from 52 to 71 years, average 64 years. Pattern of perception of Haidinger brushes was examined by a coordinator. Patients were also examined regarding visual acuity and findings by optical coherence tomography (OCT). Results: There were 5 patterns of perception of Haidinger bruches: invisible, blurred, lack of center, eccentric and normal. All the cases gained good visual acuity 6 months after surgery and reported either eccentric or normal. There was no correlation between findings by Haidinger brush and OCT. Conclusion: Pattern of perception of Haidinger brushes could be divided into 5 types in eyes with idiopathic macular hole. There was a fixed step in the recovery of foveal function after surgery.
