The purpose of this study was to evaluate the effect of Korean red ginseng (KRG) on ocular blood flow in patients with glaucoma. In a prospective, randomized, placebo-controlled, double-masked crossover trial, 36 patients with open-angle glaucoma were consecutively recruited. Subjects were randomly assigned into two groups. Group A received 1.5 g KRG, administered orally three times daily for 12 weeks, followed by a wash-out period of 8 weeks and 12 weeks of placebo treatment (identical capsules filled with 1.5 g corn starch). Group B underwent the same regimen, but took the placebo first and then KRG. Blood pressure, heart rate, and intraocular pressure were measured at baseline and at the end of each phase of the study. Visual field examination and ocular blood flow measurements by the Heidelberg Retina Flowmeter were performed at baseline and at the end of each phase of the study. Changes in blood pressure, heart rate, intraocular pressure, visual field indices, and retinal peripapillary blood flow were evaluated. Blood pressure, heart rate, intraocular pressure, and visual field indices did not change after placebo or KRG treatment. After KRG treatment, retinal peripapillary blood flow in the temporal peripapillary region significantly improved (p=0.005). No significant changes were found in retinal peripapillary blood flow in either the rim region or the nasal peripapillary region (p=0.051 and 0.278, respectively). KRG ingestion appears to improve retinal peripapillary blood flow in patients with open-angle glaucoma. These results imply that KRG ingestion might be helpful for glaucoma management.

A 15-year-old castrated male Persian (Case 1), an 1.5-year-old castrated male Bengal (Case 2), and an 1.5-year-old spayed female Russian Blue (Case 3) cats were presented with iris-color change and suspicious anterior chamber mass. Complete ophthalmic examination revealed a vascularized or blood tinted mass filling with anterior chamber accompanied by rubeosis iridis, dyscoria, keratic precipitates, and severe aqueous flare. Ocular ultrasonography showed an iridociliary mass with blood flow signal in Case 1. Abdominal ultrasonography also revealed suspicious metastatic involvements of liver and spleen in this cat. Case 2 and 3 were suspected of being infected with feline infectious peritonitis. Topical antibiotic/steroid combinations were prescribed to control the uveitis in all 3 cases, although enucleation was initially considered for palliative pain management in Case 1. Anterior chamber mass had almost completely disappeared after topical medications and uveitis has been successfully managed, remaining in sight, even though ocular hypertension developed 1 month later in Case 1.
