  "abstract": "Background/Aims To evaluate the effects of intraocular pressure (IOP)-lowering agents in highly myopic eyes.Methods Highly myopic patients with axial length (AL) data for longer than 5 years were included. The changes in IOP, AL and myopic macular complications during the study period were compared between the eyes treated with IOP-lowering agents (treatment group) and those never treated (control group).Results The treatment (30 eyes of 30 patients) and control (90 eyes of 90 patients) groups had comparable baseline characteristics except for IOP, which was significantly higher in the treatment group (p=0.020). During the study period, the treatment group showed a greater mean percentage decrease in IOP per year compared with the control group (−2.13±2.51% /year vs+0.30 ± 2.31% /year; p<0.001). The mean change in AL per year was +0.032 ± 0.050 mm/year in the treatment group and +0.058 ± 0.054 mm/year in the control group (p=0.022), and the difference was more pronounced in eyes with posterior staphyloma or without dome-shaped macula. The progression of myopic macular degeneration (MMD), myopic retinoschisis and myopic choroidal neovascularisation during the study period was comparable between groups, but the increase in MMD category was significantly less frequent in the treatment group (3.3% vs 20.0%; p=0.040). In the multivariate analysis, use of IOP-lowering agents was associated with both decreased axial elongation and lower likelihood of MMD category increase.Conclusion IOP-lowering agents may be effective in alleviating axial elongation and progression of myopic maculopathy in highly myopic eyes.",
