We studied the effect of 1% apraclonidine (Iopidine(R)) on the ocular hypotensive action and its ocular side effects following laser surgery for glaucoma. One hundred twenty patients with primary angle closure glaucoma underwent argon laser peripheral iridotomy and 40 patients with primary open angle glaucoma were treated with laser trabeculoplasty. Mean lOP of eyes instilled with 1% apraclonidine fell by 16% 3 hours after instillation in laser iridotomy cases and by 28% 3 hours after instillation in trabeculoplasty cases. lOP elevation greater than lO mmHg was found in 18 eyes (30%) of the control group in iridotomy cases and 4 eyes (40%) in trabeculoplasty cases, but none in the apraclonidine group in both treated cases for the first three hours. Apraclonidine reduced the incidence and magnitude of potentially harmful lOP elevations after laser irdotomy and trabeculoplasty.

PURPOSE: To perform an economic evaluation of the different treatment methods available for primary open-angle glaucoma in a Korean setting, including medication, selective laser trabeculoplasty, or surgery. METHODS: Three independent Markov chains were constructed for each treatment option to simulate treatment progress and to evaluate the total treatment costs for each initial strategy. The Markov chain consisted of different stages (5, 10, 20 stages), with each stage being one year. Assuming 1000 patients, a Monte Carlo simulation was iterated 1000 times to evaluate the cost of treatment over 5, 10 and 20 years. RESULTS: During the initial five years, medication as the initial treatment was the most expensive, whereas laser trabeculoplasty was the cheapest. After ten years, surgery became the cheapest treatment. In ten years, if the success rate of surgery is greater than 30.1%, it was more economic to choose surgery as the initial treatment. For laser trabeculoplasty, if the success rate was greater than 16.3%, laser treatment was more economical than was medication. Our model shows that only if the annual cost of medication decreases to 60,000 won or 55,000 won, then the cost of choosing medication as the initial treatment strategy will be more economical than that of laser therapy or surgery, respectively. CONCLUSIONS: The economic value of choosing laser therapy as the initial treatment strategy is the greatest over five simulated-years, whereas surgery had the greatest economic value over more than ten years.

BACKGROUNDAhmed glaucoma valves (AGV) has been used for decades, but there is no detailed report about the efficacy of AGV in Chinese glaucoma patients. This study aimed to compare the intraocular pressure (IOP) lowering efficacy and side effects of S-2 polypropylene and PF-7 silicone AGV implantation in Chinese refractory glaucoma patients.

METHODSPatients were divided into S-2 model AGV group and FP-7 model AGV group. The complete and qualified surgical success rate, change of IOP, number of anti-glaucoma medications used and postoperative complications were recorded and analyzed.

RESULTSAverage follow-up time was comparable between two groups. IOP was reduced from (37.9 ± 12.7) mmHg preoperatively to (17.3 ± 5.3) mmHg at the last follow-up in S-2 group and reduced from (39.9 ± 14.4) mmHg to (17.7 ± 4.9) mmHg in FP-7 group. Anti-glaucoma medications were reduced from 3.8 ± 0.2 to 1.5 ± 0.2 in S-2 group, and 3.5 ± 0.2 to 0.7 ± 0.2 in FP-7 groups. The cumulative success rates were comparable in two groups, which were 61.2% and 72.1% in S-2 group and FP-7 group respectively. When IOP reduction criteria was used, complete success rates were 30.6% and 51.2% for S-2 and FP-7 groups, and qualified success rates were 86.1% and 92.7% separately. In both groups, the major complication was hypotony, and the previous trabeculectomy of patients was the major risk factor for surgery failure.

CONCLUSIONSIn this short-term retrospective study, S-2 AGV is showed at least as effective as FP-7 AGV in IOP reduction, but associated with higher rate of complications. Previous trabeculectomy is a principle risk factor for AGV implantation failure. These clinical outcomes are important for converting use of the FP-7 silicon AGV in Chinese refractory glaucoma patients.

OBJECTIVE: To observe the effects of acupuncture combined with phacoemulsification for cataract with glaucoma. METHODS: Sixty-eight patients with cataract and angle-closure glaucoma were randomly divided into an observation group and a control group, 34 cases in each one. The patients in the control group were treated with phacoemulsification. Based on the treatment in the control group, the patients in the observation group were treated with and acupuncture at acupoints around eyes; the treatment was given once every other day, and 15-day treatment constituted a course, and 2 courses (60 days) were given. The intraocular pressure (IOP), visual acuity, pain severity, aqueous outflow (F value) and clinical symptoms were observed in the two groups before treatment and after 1 d, 7 d, 30 d and 60 d of treatment. RESULTS: The IOP after 1 d, 7 d, 30 d and 60 d of treatment in the observation group was lower than that in the control group (all <0.05), while the visual acuity after 7 d, 30 d and 60 d of treatment in the observation group was higher than that in the control group (all <0.05). Compared before treatment, the IOP was significantly decreased after 1 d, 7 d, 30 d and 60 d of treatment in the two groups, and the visual acuity was significantly increased after 7 d, 30 d and 60 d of treatment in the two groups (all <0.05). The pain scores and F value after 7 d, 30 d and 60 d of treatment in the observation group were lower than those in the control group (all <0.05). Compared before treatment, the pain scores and F value after 7 d, 30 d and 60 d of treatment were significantly reduced in the two groups (all <0.05). After 60 d of treatment, the number of patients who presented general clinical symptoms in the observation group was significantly lower than that in the control group (<0.05). CONCLUSION Based on phacoemulsification, acupuncture and could significantly reduce the IOP and F value, relieve pain and improve visual acuity in patients with cataract and glaucoma.

OBJECTIVE: To observe the clinical effect of acupuncture for glaucoma-induced optic atrophy. METHODS: A total of 70 patients (89 affected eyes) with glaucoma-induced optic atrophy were randomized into an observation group and a control group, 35 cases in each group. The control group was given basic western medicine treatment. In the observation group, on the basis of the treatment in the control group, acupuncture was applied at main acupoints i.e. Baihui (GV 20), Shangjingming (Extra), Chengqi (ST 1), Fengchi (GB 20), Zusanli (ST 36), combined with supplementary acupoints based on syndrome differentiation, once every three days, twice a week. The treatment for 3 months was required in both groups. Before treatment, after treatment and in follow-up of 6 months after treatment, the best corrected visual acuity (BCVA), intraocular pressure (IOP), indexes of visual field (visual field index [VFI], mean deviation [MD], pattern standard deviation [PSD]) and mean thickness of retinal nerve fiber layer (RNFL) were observed in the two groups. RESULTS: Compared before treatment, BCVA was decreased after treatment and in follow-up in the control group (P<0.05); in the follow-up, BCVA in the observation group was higher than that in the control group (P<0.05). On each time point before and after treatment, there was no significant difference within or between the two groups (P>0.05). After treatment and in the follow-up, the mean thickness of RNFL was larger than the control group (P<0.05). CONCLUSION On the basis of the basic western medicine treatment, acupuncture can delay the decline of vision and the thinning of retinal nerve fiber layer in patients with glaucoma-induced optic atrophy.

We used endoscopic laser photocoagulation to treat neovascular glaucoma in eight eyes of seven patients. New vessels of the iris and anterior chamber disappeared or stabilized after photocoagulation in seven eyes (88%), while the vision improved in four eyes (50%). The endoscopy was excellent for observing the peripheral retina and ciliary process tissue. We found the endoscopic laser was suitable for wider photocoagulation of ischemic retina against media opacity.

PURPOSE: To compare the efficacy of selective laser trabeculoplasty (SLT) in patients treated with either latanoprost or dorzolamide/timolol fixed combination (DTFC) for primary open-angle glaucoma. METHODS: This retrospective study included 92 consecutive patients who underwent a 180-degree SLT for the first time. The subjects divided into two groups:patients who received latanoprost (n = 63) or DTFC (n = 29) before and after SLT. The main outcome measure was intraocular pressure (IOP) decrease over five years after SLT. The mean IOP change, mean percentage of IOP reduction, and success rates were compared between the patients treated with latanoprost and the patients treated with DTFC. Success was defined as an IOP decrease ≥ 3 mm Hg or IOP reduction ≥ 20% without additional medications, laser surgery, or glaucoma surgery. RESULTS: At the postoperative one-year follow-up, the mean IOP was 15.7 ± 2.2 mm Hg in the latanoprost group and, 16.2 ± 2.4 mm Hg in the DTFC group. At the postoperative five-year follow-up, the mean IOP was 15.1 ± 2.5 mm Hg in the latanoprost group and, 14.6 ± 1.7 mm Hg in the DTFC group. There were no statistically significant differences in IOP change, percentage IOP reduction, or success rate between the groups at each time point after the SLT (p > 0.05). CONCLUSIONS: Selective laser trabeculoplasty showed a reasonable efficacy in lowering the IOP over a five-year follow-up period. There were no significant differences in IOP lowering effect or success rate between the patients treated with latanoprost or DTFC.
