Abstract:
Purpose:To investigate the influence of intraocular pressure (IOP)-lowering eye drops on myopic retinoschisis.
Methods:We investigated myopic retinoschisis patients with high myopia (defined as a myopic refractive error more than -8.0 dioptersor an axial length longer than 26.5 mm), who were suspected of having glaucomatous optic neuropathy, using IOP-loweringeye drops between April 2014 and December 2018. We retrospectively analyzed the changes in optical coherence tomographyfindings after 6 months using IOP-lowering eye drops. The progression of retinoschisis was assessed by analyzing retinalvolume changes. A decrease in the total retina volume and a decrease in volume more than 10% in one section out of five withoutmore than a 10% volume increase in any other section was defined as resolution of myopic retinoschisis. The opposite casewas defined as an aggravation.
Results:We analyzed 17 eyes of 15 patients with high myopia. Six of 17 eyes (35.3%) showed a resolution of myopic retinoschisisat 6 months after using IOP-lowering eye drops. Of the 17 eyes, two (11.8%) experienced progression of myopicretinoschisis. Seven out of 14 eyes (50.0%) who were followed-up over 1 year showed resolution of myopic retinoschisis, andtwo eyes (14.3%) experienced progression of myopic retinoschisis. There was no macular hole development or posterior vitreousdetachment during the follow-up period in the seven eyes, and there was no significant correlation between the absolute valueof the initial IOP, axial length, IOP change, and degree of improvement of myopic retinoschisis.
Conclusions:The use of IOP-lowering eye drops on highly myopic eyes with retinoschisis showed a significant improvement ofmyopic retinoschisis, when compared to previous studies. These findings suggest the possibility of IOP-lowering eye drops delayingor improving the natural course of myopic retinoschisis.
