Bilateral CNV associated with optic nerve drusen treated with photodynamic therapy with verteporfin

PURPOSE: To report a case of bilateral choroidal neovascularization (CNV) associated with optic nerve drusen (OND) treated with photodynamic therapy (PDT) with verteporfin. METHODS: A 10-year-old girl with juxtapapillary CNV in the right eye and juxtapapillary and juxtafoveal CNV in the left eye associated with OND underwent PDT with verteporfin in both eyes. RESULTS: Visual acuity increased from 20/160 to 20/25 in the right eye and from 20/1000 to 20/25 in the left eye after two sessions of PDT and 2 years of follow-up. CNV showed no leakage after two PDT sessions in both eyes and no recurrence was observed. CONCLUSIONS: Subfoveal CNV is an uncommon complication of OND and excellent anatomic and functional results can be obtained with PDT.     

合并成型性渗出的急性前葡萄膜炎与HLA-B27的相关性研究

目的 探讨急性渗出性前葡萄膜炎与HLA-B27的相关性。方法 对53例前房内出现成型性渗出的急性前葡萄膜炎（AAUPE）患者及61例前房内无成型性渗出的急性前葡萄膜炎（AAU）患者进行HLA-B27的检测,并结合临床表现加以分析。结果 成型性渗出的AAUPE患者的HLA-B27阳性率为100％,而无成型性渗出的AAU患者的HLA-B27阳性率仅为50.8％。二者有显著差异性（P<0.01）。两组HLA-B27阳性的病人强直性脊柱炎发生率分别为50.0％和42.9％。结论 结果进一步证实了HLA-B27与成型性渗出密切相关的论点。提示检测AAU患者HLA-B27的阳性率,发现成型性渗出裂隙灯检查似与血清法检测同样准确。     

Levodopa-carbidopa with occlusion in older children with amblyopia

PURPOSE: To study the role of levodopa-carbidopa in supplementing occlusion therapy in older children with strabismic or anisometropic amblyopia. Methods: A clinical study was performed on 40 amblyopic children (19 strabismic and 21 anisometropic), 6 to 18 years old (mean age, 10.9 years). They received an average dose of 1.86 mg/kg/day (1.33-2.36 mg/kg/day) of levodopa and carbidopa (4:1 ratio) or a placebo in 3 divided doses over a 4-week period, combined with full-time occlusion. The occlusion was continued for the study duration of 3 months. Early Treatment Diabetic Retinopathy Study visual acuity charts and Cambridge low-contrast gratings for contrast sensitivity (CS) were used to assess visual functions. Tolerance and compliance with occlusion and capsule consumption were assessed. RESULTS: Visual acuity of the nonamblyopic eye did not deteriorate during the study in either group. CS decreased by 22 units in the levodopa group and increased in the placebo group by 53 units at the first month. The CS in the levodopa group recovered later by the third month of follow-up. Both the levodopa and the placebo groups showed significant improvement in visual function in the amblyopic eye (P <.001). Overall changes in logarithm of minimum angle of resolution values and CS in the amblyopic eyes were similar in both groups (P >.05). Strabismic and anisometropic amblyopes did not behave differently. Drug tolerance, occlusion compliance, and capsule ingestion compliance were similar between the groups, with no significant side effects. CONCLUSIONS: Clinically, levodopa supplementation does not offer any advantage over occlusion alone. Moreover, the risk of occlusion amblyopia could increase with the use of drugs like levodopa that might affect the plasticity of the visual cortex.     

Phacotrabeculectomy with mitomycin C in patients with uveitis

PURPOSE: To evaluate the safety and efficacy of combined phacoemulsification, intraocular lens implantation, and trabeculectomy with mitomycin C for the management of uveitic complications. DESIGN: Retrospective case-control study. METHODS: We conducted a retrospective review of the records of 23 consecutive eyes with chronic noninfectious uveitis (uveitic group) and 43 nonuveitic eyes (control group) that had received primary phacotrabeculectomy. Mitomycin C was used in all the uveitic eyes. Considering the high preoperative intraocular pressure (IOP) of the uveitic group, nonuveitic eyes that had a preoperative IOP of >or=20 mm Hg or that had been given two or more medications were included in the control group. All patients were followed for at least one year. The main outcome measures were postoperative vision, IOP control, complications, and acute uveitis relapse rates. RESULTS: Visual outcome of the uveitic group was similar to the control group. In the uveitic group, the success rate of IOP control (91.3% at one year, 84.8% at two years) was favorable but was significantly lower than in the control group (P = .0423). Complications were comparable between the groups. Primary surgical failure in the uveitic group was associated with the postoperative acute uveitis attack. In the uveitic group, the acute uveitis attack rate showed no change after surgery (P = .283). CONCLUSION: With adequate inflammation suppression, phacotrabeculectomy with mitomycin C is an effective and safe therapeutic option for the management of secondary cataract and glaucoma in uveitic eyes. A lower surgical success rate of the uveitic group might be attributable to the postoperative inflammation recurrence.

目的：观察小梁切除联合超声乳化白内障吸除术在原发性闭角型青光眼(包括急性闭角型青光眼与慢性闭角型青光眼)合并白内障患者中的临床治疗效果及对并发症的影响。

方法：选取2014-01/2016-07在我院诊治的青光眼合并白内障患者60例60眼,采用随机数字方法分为对照组(30例30眼)和观察组(30例30眼)。对照组采用小梁切除术治疗,观察组采用小梁切除联合超声乳化白内障吸除治疗,比较两组临床效果及并发症发生率情况。

结果：观察组术后视力与对照组相比差异无统计学意义(P>0.05); 观察组术后眼压水平低于对照组,差异有统计学意义(P<0.05); 观察组术后前房深度大于对照组,差异有统计学意义(P<0.05); 观察组术后并发症发生率为7%,显著低于对照组的23%,差异有统计学意义(P<0.05)。

结论：原发性闭角型青光眼合并白内障患者在小梁切除术基础上联合超声乳化白内障吸除术治疗效果理想,并发症发生率相对较低。     

Epikeratoplasty with nonlyophilized tissue in children with aphakia

We studied 75 epikeratoplasty procedures using nonlyophilized tissue performed by eight ophthalmic surgeons in 70 eyes (47 patients) to correct for aphakia in children less than 8 years of age (mean age, 3.4 +/- 2.1 years). Of the 47 patients in the study, 24 were girls and 23 were boys; 23 patients had bilateral surgery. Seven of the epigrafts required removal; two were not replaced, and five underwent successful repeat epikeratoplasty. Overall, the success rate (that is, the percentage of epigrafts that remained optically and functionally clear throughout the course of this study) for the epikeratoplasty procedure was 89% (62 of 70 eyes) for initial surgery and 96% (67 of 70 eyes) for repeat surgery. The average spherical equivalent was +14.4 +/- 3.7 diopters preoperatively and +0.3 +/- 2.9 diopters one year after the operation. One year after the final surgical procedure, 42 of 56 eyes (75%) were within 3 diopters of emmetropia. In the 29 verbal patients, best-corrected visual acuity was 20/100 or better in 25 (86.2%) one year after the operation.
