Optical Quality and Related Factors in Ocular Hypertension: Preliminary Study.

Background. To evaluate the optical quality and related factors in patients with ocular hypertension (OHT). Methods.

[The change of the level of the vascular endothelial growth factor in aqueous humor of patients with neovascular glaucoma before and after anterior retinal cryotherapy].

Objective: To compare the change of the level of the vascular endothelial growth factor (VEGF) in aqueous humor of patients with neovascular glaucoma (NVG) before and after anterior retinal cryotherapy and investigate the effects of the fluctuation of VEGF on the neovascularization of iris.

Methods: 28 patients with neovascular glaucoma were undergone iris fluorescent angiography to identify the area and amount of new vessels before and after anterior retinal cryotherapy. The neovascularization of iris was observed from 7 to 14 days by iris fluorescent angiography to confirm the regression of new vessels in iris before trabeculectomy.
