Purpose: To introduce a novel biomarker for screening of primary open-angle glaucoma (POAG) by detecting and measuring brain-derived neurotrophic factor (BDNF) in the serum of normal subjects and patients with early stage of glaucoma.
Methods: Twenty-five glaucoma patients as the case group and 25 age- and sex-matched normal persons as the control group were tested. The control group comprised 19 men and 6 women, with the mean age of 59.
Purpose: The aim of this study was to detect and measure brain-derived neurotrophic factor (BDNF) in the tears of normal subjects and patients with normal-tension glaucoma (NTG).
Materials And Methods: Twenty patients with NTG as the case group and 20 normal subjects with the same age range as the control group were tested. The control group consisted of 16 men and 4 women, ranging in age from 40 to 75, without any apparent ocular or systemic disease.

Purpose: To evaluate the efficacy, and safety of transcutaneous electrical stimulation (TES) to accelerate corneal nerve regeneration and improved recovery from corneal hypesthasia after laser-assisted in situ keratomileusis (LASIK).
Setting: Khodadoust Eye Hospital, Shiraz, Fars, Iran
Methods: This prospective, randomized, clinical study comprised 40 eyes of 20 patients scheduled to undergo bilateral LASIK. In each patient, one eye was randomly assigned to receive transcutaneous electrical stimulation (20 HZ) for 60 minutes, and the other eye allocated as control.
