Objective: To investigate the effect of latanoprost in IOP after laser iridectomy or filtering surgery Methodology: Patients of chronic angle closure glaucoma post laser iridectomy or filtering surgery were given latanoprost 0.005 percent eye drop in the evening for 2-6 weeks after a washout period ranging from 5 days - 28 days. IOP was measured at 9:00 a. m., 1:00 p.m. and 5: 00 p.m. per patient using a calibrated goldmann applanation tonometer Results: 29 patients were enrolled in study. There was a significant reduction in IOP among these patients Conclusion: Latanoprost 0.005 percent provides a significant reduction in IOP among patients with residual angle closure after laser iridectomy or filtering surgery.

This study reports the influence of miotics (pilocarpine) on the visual field by comparing two visual fields, one at the miotic state and the other at normal pupil size. The measurements from the Goldmann perimetry test of 10 ocular hypertensive eyes (7 patients) and 10 glaucomatous eyes (8 patients) were used. The visual field was analyzed using an Esterman grid for functional estimation and section paper for gross evaluation. The results were as follows; 1. A decrease in pupillary size eaused not only a decrease in the gross visual field but also a reduction in the functional visual field. 2. The pupillary size did not influence absolute scotoma.

Mitomycin-C(MMC) has been increasingly used as adjunct chemotherapy during glaucoma filtering surgery in order to increase the success rate, because of its ability to inhibit the proliferation of fibroblast. Although MMC demonstrates toxic effects in the anterior segment of the eye, few studies on its retinal toxicity have been reported. Therefore, this study was performed to investigate the retinal toxicity of MMC in the rabbit after intra cameral irrigation. After anesthesia, 1 ml of MMC(40 mg/ml) was intracamerally irrigated in right eye and 1ml of balanced salt solution(BSS) was used as control in the left eye. The electroretinogram was checked before, 2 and 7 days after intracameral MMC irrigation. The fundus examination and histopathology by light microscopy and transmission electron microscopy were performed at 7days after MMC irrigation. On electroretinogram, scotopic b-wave amplitude in MMC irrigated eye was significantly decreased 7 days after irrigation as compared with BSS irrigated eye. The retina in MMC irrigated eye was normal on the fundus findings and histopathology by light microscopy and transmission electron microscopy 7 days after irrigation. This findings suggest that intracameral irrigation of MMC may induce the functional disturbance rather than structural alteration of retina.

OBJECTIVETo assess the efficacy of acupuncture for glaucoma.

METHODSThe search was conducted through database to identify randomized controlled trials of acupuncture for glaucoma until September 2010. The quality assessment, data extraction and Meta-analysis were performed by Cochrane Handbook for Systematic Re views of Interventions.

RESULTSEight articles were included. Meta-analysis showed that acupuncture did not decrease intraocular pressure compared with eye drops [SMD = -0.1 66, 95% CI (-1.45, 0.13)]. However, acupuncture increased the effectiveness rate of treatment for glaucoma [OR = 4.45, 95% CI (1.96,10.09)]. Compared with placebo, acupuncture did not decrease intraocular pressure 20 min after acupuncture (P = 0.13) and 24 hours after acupuncture (P = 0.21). Nonetheless, acupuncture increased the effectiveness rate of treatment for glaucoma [OR = 45.00, 95% CI (9.73, 208.08)]. Compared with acupuncture, quantitative acupuncture manipulation increased the effectiveness rates of treatment for glaucoma [OR = 2.23, 95% CI (1.14, 4.36)].

CONCLUSIONAcupuncture therapy has potential to increase effectiveness rates of treatment for glaucoma. It lacks reliable evidence to prove that acupuncture decreases intraocular pressure. More trials with high quality are needed to estimate adverse effects and cost effectiveness of acupuncture therapy.

PURPOSE: Long-term use of topical medication is needed for glaucoma treatment. One of the most commonly prescribed classes of hypotensive agents are prostaglandin analogs (PGs) used as both first-line monotherapy; as well as in combination therapy with other hypotensive agents. Several side effects of eye drops can be caused by preservatives. The purpose of this study was to evaluate the effects of PGs with varying concentrations of benzalkonium chloride (BAC), alternative preservatives, or no preservatives on human conjunctival fibroblast cells. METHODS: Primary human conjunctival fibroblast cells were used in these experiments. Cells were exposed to the following drugs: BAC at different concentrations, bimatoprost 0.01% (with BAC 0.02%), latanoprost 0.005% (with BAC 0.02%), tafluprost 0.0015% with/without 0.001% BAC and travoprost 0.004% (with 0.001% Polyquad) for 15 and 30 minutes. Cell cytotoxicity was evaluated by phase-contrast microscopy to monitor morphological changes of cells, Counting Kit-8 (CCK-8) assay to cell viability, and fluorescent activated cell sorting (FACS) analysis to measure apoptosis. RESULTS: BAC caused cell shrinkage and detachment from the plate in a dose-dependent manner. Morphological changes were observed in cells treated with bimatoprost 0.01% and latanoprost 0.005%. However, mild cell shrinkage was noted in cells treated with tafluprost 0.0015%, while a non-toxic effect was noted with travoprost 0.004% and preservative-free tafluprost 0.0015%. CCK-8 assay and FACS analysis showed all groups had a significantly decreased cell viability and higher apoptosis rate compared with the control group. However, travoprost 0.004% and preservative-free tafluprost 0.0015% showed lower cytotoxicity and apoptosis rate than other drugs. CONCLUSIONS: This in vitro study revealed that BAC-induced cytotoxicity is dose-dependent, although it is important to emphasize that the clinical significance of toxicity differences observed among the different PGs formulations has not yet been firmly established. Alternatively preserved or preservative-free glaucoma medications seem to be a reasonable and viable alternative to those preserved with BAC.

Previous reported ocular complications of interferon alfa administration are extremely rare. These include oculomotor palsy, corneal allograft rejection, retinal hemorrhage and cotton wool patches. A 15-year-old boy with chronic hepatitis B was treated with interferon alpha for six months, and then developed glaucoma. After the interferon therapy had been discontinued the glaucoma improved. Accordingly, we report a case of glaucoma development during the course of interferon alpha therapy for chronic hepatitis B.

OBJECTIVETo evaluate the therapeutic effect of compound anisodine (CA) for patients with primary open angle glaucoma (POAG).

METHODSAccording to the modified Hodapp-Parrish-Anderson Visual Fields Grading System, 46 patients with moderate stage POAG were randomized to receive compound anisodine injection (CA group) or venoruton tablets (control group). Visual acuity (VA), IOP, fundus, visual fields (VF) and the blood flow of optic nerve were observed.

RESULTSThe mean of defect (MD) was decreased in CA group after treatment. The PSV and EDV of ophthalmic artery were remarkably improved in both groups, as well as the PSV, EDV and RI of retinal central artery. Compound anisodine was superior in improving hemodynamics of ophthalmic artery and retinal central artery to venoruton.

CONCLUSIONCompound anisodine can protect optic nerve of POAG through improving the visual function and blood supply of optic nerve.

PURPOSE: The purpose of this study is to assess patient attitudes towards anti-glaucoma medication and their association with adherence, visual quality of life, and personality traits. MATERIALS AND METHODS: One hundred and forty-seven glaucoma patients were enrolled this study. The participants were divided into 'pharmacophobic' and 'pharmacophilic' groups according to their scores on the Modified Glaucoma Drug Attitude Inventory (MG-DAI). To establish a correlation with patient drug attitude, each group had their subjective drug adherence, visual quality of life, and personality traits examined. For personality traits, the Myers-Briggs Type Indicator (MBTI) was used to sub-classify each group. RESULTS: Among the patients analyzed, 91 (72.80%) patients showed a 'pharmacophobic' attitude and 34 (27.20%) patients showed a 'pharmacophilic' attitude. The pharmacophobic group tended to have worse adherence than the pharmacophilic group. Personality dichotomies from the MBTI also showed different patterns for each group. CONCLUSION: In glaucoma patients, pharmacological adherence was influenced by their attitude towards drugs; an association might exist between drug attitude and underlying personality traits.
