Chronic macula holes (MHs) have distinct features compared to those of acute symptomatic MH on OCT findings.
Chronic macula holes (MHs) have distinct features compared to those of acute symptomatic MH on OCT findings, according to a paper published in Retina.
Dr C. Yun et al., Department of Ophthalmology, Korea University College of Medicine, Seoul, South Korea, retrospectively reviewed OCT images of 13 eyes of 13 patients with chronic MH and 67 eyes of 67 patients classified as controls.
Chronic MH was identified as MH observed without undergoing surgical treatment for at least a year. The OCT parameters were compared between chronic and acute MH.
The basal hole diameter did not differ when chronic MH eyes and control eyes were compared. However, the minimum hole diameter of chronic MH was larger than the control diameters. Hole height and MH index were smaller in the chronic MH group, compared to the control group.
Only the chronic MH group presented with retinal pigment epithelial atrophy and intraretinal fluid was less frequently observed, compared to the control group. The findings could be useful for identifying the differences between chronic and acute MH.
