To study the variability in dimensions of macular holes with Optical Coherence Tomography (OCT) and its clinical significance.
A total of 22 patients with clinical diagnosis of macular hole were examined using optical coherence tomography. OCT imaging was conducted through dilated pupil, by an experienced examiner. The images were analysed and macular hole diameters were measured at the surface, at the neck (minimum diameter) and at the level of retinal pigment epithelium (base diameter) along with the height of the hole and thickness of the surrounding retina.
Quantitative analysis revealed average base diameter of 771µ (range: 336–1384), minimum diameter of 379µ (range: 149–798) and surface diameter of 696µ (range: 299–1372). Average height of the hole was 411µ (113–805). Surrounding retinal thickness was 333µ (214–416). The size of the hole and thickness of surrounding retina correlated with the level of visual acuity.
OCT is a versatile non–invasive, non–contact imaging technique. It is useful for visualizing and quantitatively characterizing macular holes, which might be helpful in assessing the surgical outcomes.
