Higher axial length variation between two eyes tied to inter-eye glaucoma severity with quicker progression: Study
A new study published in the recent issue of Ophthalmology journal found that the glaucoma in the longer eyes tend to be more severe and to advance more quickly when there was an axial length variation of more than 1.0 mm, the findings of this study were .
Elevated intraocular pressure (IOP) can compress retinal ganglion cell axons at the lamina cribrosa, resulting in death and interrupting axonal transport. Long axial length (AL) is also independently linked to an elevated the risk of normotensive primary open angle glaucoma (OAG), and myopia is another well-known risk factor for glaucoma. Thus, Min Gu Huh and team sought out to determine if individuals with asymmetric axial length had a different inter-eye glaucoma development and severity.
The long-term observational research included patients over the age of 20 who were diagnosed with glaucoma at Seoul National University Hospital in Seoul, Korea, between 2010 and 2020. The patients who had an axial length difference of more than 1.0 mm and bilateral glaucoma were included. The paired test was used to compare baseline and follow-up clinical data after each individual's eyes and were classified as "longer eye" or "shorter eye." The main finding of this study was that those with asymmetric axial length had varied clinical characteristics.
