PURPOSE: To report the case of delayed suprachoroidal hemorrhage after Ahmed valve implantation in a neovascular glaucoma (NVG) patient. CASE SUMMARY: A 74-years-old male visited the hospital with ocular pain in the left eye. He had a history of vitrectomy and Intraocular lens (IOL) scleral fixation due to trauma in the left eye. NVG was diagnosed and Ahmed valve was implanted in his left eye. Three days later, hypotony occurred with all quadrant choroidal detachment. Next day, raised intraocular pressure (IOP) was checked and anterior chamber was flat on slit lamp examination. Vitreous hemorrhage and suprachoroidal hemorrhage were suspected. We performed anterior chamber formation with viscoelastics. The anterior chamber became deeper and hemorrhage gradually decreased. A month later, the patient visited us with severe ocular pain. Raised IOP and shallow anterior chamber due to moderate hyphema and anteriorly placed IOL were found. Retinal detachment was suspected on B-scan. Vitrectomy, IOL removal, silicone oil insertion, and Ahmed valve removal were performed. CONCLUSIONS: We report we experienced one patient of delayed suprachoroidal hemorrhage after Ahmed valve implantation and he had poor prognosis.

Schizandra chinensis Baillon is a traditional folk medicine plant that is used to treat and prevent several inflammatory diseases and cancer in Korea, but the underlying mechanisms involved in its anti-allergic activity are not fully understood. This study was designed to investigate mechanisms of anti-allergic activity of a Schizandra chinensis Baillon water extract (SCWE) in immunoglobulin E (IgE)-antigen complex-stimulated RBL2H3 cells and to assess whether gastric and intestinal digestion affects the anti-allergic properties of SCWE. Oxidative stress is an important consequence of the allergic inflammatory response. The antioxidant activities of SCWE increased in a concentration-dependent manner. RBL-2H3 cells were sensitized with monoclonal anti-dinitrophenol (DNP) specific IgE, treated with SCWE, and challenged with the antigen DNP-human serum albumin. SCWE inhibited beta-hexosaminidase release and expression of interleukin (IL)-4, IL-13, and tumor necrosis factor-alpha (TNF-alpha) mRNA and protein in IgE-antigen complex-stimulated RBL2H3 cells. We found that digested SCWE fully maintained its antioxidant activity and anti-allergic activity against the IgE-antigen complex-induced activation of RBL-2H3 cells. SCWE may be useful for preventing allergic diseases, such as asthma. Thus, SCWE could be used as a natural functional ingredient for allergic diseases in the food and/or pharmaceutical industries.

A 63-year-old man with a history of liver transplantation presented to our clinic complaining of visual disturbance. He had been receiving tacrolimus (FK 506) for 30 months (6 mg/day for 2 years and 3 mg/day for 6 months); he reported that the visual disturbance began while taking tacrolimus. A full ophthalmologic examination and electrophysiologic and imaging studies were performed. The best corrected visual acuity was 0.1 in both eyes. There were no abnormal finding in the anterior segment, pupillary reflexes were normal and, there was no swelling in either optic disc. Although the foveal reflex was slightly decreased, fluorescein angiography revealed non-specific signs, with the exception of a window defect. A multifocal electro-retinogram revealed decreased amplitude of the central ring. A Swedish interactive threshold algorithm-standard 10-2 visual field test revealed a central scotoma. These findings suggest that tacrolimus may result in maculopathy. Therefore, careful ophthalmologic examination is necessary in the patients taking tacrolimus.
