Background Vogt-Koyanagi-Harada syndrome (VKH) is a multisystem disorder, characterized by the T-cell-mediated autoimmune process directed
against melanocytic antigens in the ocular, nervous, auditory and integumentary systems. The ocular hallmarks of the disease
involve severe bilateral panuveitis associated with exudative retinal detachment. Case report We report a pediatric case of probable VKH Syndrome with isolated ocular findings, in which bilateral vitritis, papillitis
and serous retinal detachments involving the macula with intra-retinal edema and choroideal thickening were detected. Intervention Subtenon triamcinolone acetonide injection was performed in addition to systemic corticosteroid and cyclosporine treatments.
Evolution Prompt improvement was seen in the ocular manifestations of VKH syndrome, which persisted for at least 4 months. Subtenon
corticosteroid injection, together with systemic corticosteroid and cytotoxic treatment, prevented the ocular complications
of invasive intraocular treatment modalities, and at the same time reduced the systemic corticosteroid dosage. Conclusion We recommend use of ocular invasive treatment modalities in Vogt-Koyanagi-Harada Syndrome only if the disease progression
cannot be controlled. If systemic medications fail to stop the progression of the disease activity, subtenon injections may
be considered before intraocular treatment modalities.
The authors have full control of all primary data and they will allow International Ophthalmology to review their data upon request. 相似文献

背景 曲安奈德具有抗光作用,脉络膜脱离型视网膜脱离(RD/CD)术前玻璃体腔内注射TA可减轻炎症反应,改善手术效果,但由于术前眼压低,玻璃体腔注射易引起并发症.关于后Tenon囊下注射TA在RD/CD中的有效性和安全性尚未见报道. 目的 探讨后Tenon囊下注射TA治疗RD/CD的疗效及安全性.方法 采用回顾性研究方法,收集于2010年5月至2014年6月在温州医科大学附属眼视光医院首诊为RD/CD且接受手术的患者22例22眼的病历资料,患眼均于玻璃体切割术前5d行后Tenon囊下注射TA混悬液40 mg(0.4 ml),注药后观察葡萄膜的炎性反应.使用Goldmann眼压计和B型超声仪观察注药前及注药后5d患眼眼压、脉络膜脱离高度及脱离范围的变化,同时监测血压及血糖的变化,并于注药5d后行玻璃体切割术,所有患者术后随访3个月以上. 结果 行TA的后Tenon囊下注射的22眼葡萄膜炎症状均不同程度减轻;注药前患眼平均眼压为(5.4--.2.9) mmHg(1 mmHg=0.133 kPa),注射TA后5d患眼平均眼压为(8.2±4.3) mmHg,眼压上升2.8 mmHg,差异有统计学意义(t=3.430,P<0.01).注药前患眼平均脉络膜脱离高度为5.2(3.1,6.6)mm,注药后5d平均脉络膜脱离高度为0.9(0,3.8)mm,脉络膜脱离高度显著降低,差异有统计学意义(Z=-4.198,P<0.01).注药前患眼平均脉络膜脱离范围为12(10,12)个点位,注药后5d平均脉络膜脱离范围为3(0,6)个点位,脱离范围显著下降,差异有统计学意义(Z=-4.124,P<0.01).患者注药前后血糖、血压变化的差异均无统计学意义(均P>0.05).术眼术前、术后1个月和3个月LogMAR视力分别为2.14±0.46、1.29±0.57和1.17±0.55,术后视力较术前明显好转,总体比较差异有统计学意义(F=22.060,P<0.001).视网膜复位率为95.5%.7眼术后出现高眼压,其中5眼使用局部降眼压药物治疗后恢复,2眼药物取出后眼压恢复正常. 结论 RD/CD术前行TA后Tenon囊下注射能减轻术眼葡萄膜炎反应,升高眼压及降低脉络膜脱离,对血糖、血压影响小. 相似文献

Purpose: To report a case of Staphylococcus epidermidis infection after subtenon injection (STI) of triamcinolone acetonide (TA). Design: Interventional case report.Methods: A 20-year-old patient with corneal graft rejection received STI of TA after insufficient response to topical and oral corticosteroids.Results: After conjunctival necrosis, necrotizing scleritis progressed although topical and systemic steroids were discontinued. Systemic ciprofloxacin, topical fortified amikacin, and vancomycine drops were used. Complete recovery was obtained after 3 weeks. Smears and cultures showed Staphylococcus epidermidis infection.Conclusions: Although uncommon, infectious scleritis can occur following uncomplicated subconjunctival corticosteroid injections. Infectious scleritis can be very difficult to diagnose as it may mimic an immune mediated disease. If the conjunctiva is suspected to be involved, a smear should always be taken. Prevention by sterilizing the injection site (prep and drape) and strong antibiotic prophylaxis are recommended to reduce the risk of the infectious scleritis. 相似文献

ObjectiveTo compare sub-Tenon’s block with peribulbar block in patients on oral warfarin therapy undergoing cataract surgery.Materials and methodsWe studied 100 patients on warfarin undergoing cataract surgery; randomly allocated into one of two groups; sub-Tenon’s group (group S, n = 50), and peribulbar group (group P, n = 50). In group (S), sub-Tenon’s injection of 3–5 ml of anesthetic agent was done using a 25 mm sub-Tenon’s cannula. In group (P), the peribulbar block with 3–4 ml of 2% lidocaine–hyaluronidase (10 IU/ml) and 0.5% bupivacaine was done. Pain and akinesia and postoperative complications were assessed.ResultsSub-Tenon group showed significantly higher frequency of hemorrhage compared to peribulbar group (30% versus 8%, p = 0.041), mainly of grade I. The two groups had comparable frequency of subconjunctival hemorrhage (p = 1.000). No patients experienced sight-threatening hemorrhagic complications. Pain was significantly lower in the sub-Tenon group. Akinesia was significantly better (p = 0.025) 2 min after injection and comparable from 4 to 10 min after injection in the peribulbar group. The majority of patients in the two groups reported satisfaction (p = 0.372). The surgeon expressed higher satisfaction with peribulbar block (94%) compared to sub-Tenon’s block (81%) (p = 0.064).ConclusionPeribulbar and sub-Tenon techniques were relatively safe in patients on anticoagulants during cataract operation. We recommend peribulbar technique owing to significantly less bleeding and more satisfactory akinesia response and hence surgeon comfort. 相似文献

Background At the time of posterior subtenon infusion of triamcinolone acetonide (STI-TA) in patients with diabetic macular edema (DME),
drug reflux of TA has sometimes been observed from the conjunctival incision site. We investigated the influence of this reflux
on regression of DME and postoperative intraocular pressure (IOP).
Methods STI-TA was performed on one hundred and twenty-four eyes of 88 consecutive patients with DME. Eligible eyes were divided into
two groups: those with observed drug reflux of TA and those without observed drug reflux of TA. Visual acuity (VA), foveal
thickness (FT) and IOP were monitored in each eye for up to 12 weeks after STI-TA.
Results STI-TA with drug reflux was observed in ten individual eyes of seven patients. These patients were significantly younger than
those patients without observed drug reflux. After STI-TA, both improvement of VA and regression of FT in reflux(+) eyes were
less than in reflux(-) eyes. Postoperative IOP elevation in reflux(+) eyes was much higher, and four of the ten eyes needed
anti-glaucoma therapy. This was in contrast to three of the 118 eyes without drug reflux that required anti-glaucoma therapy.
Conclusions At the time of STI-TA in DME, drug reflux of TA is a risk factor not only for insufficient reduction of edema, but also for
postoperative IOP elevation.

BackgroundResearches to find a better adjuvant in regional anesthesia are still continued until now.Dexmedetomidine prolongs anesthesia and analgesia of local anesthetics in various neural blocks as well as the onset of sensory and motor block. The objective of the present study was to evaluate the effect of adding dexmedetomidine to local anesthetics on the sensory and motor block of the subtenon block in patients undergoing phacoemulsification cataract surgery.MethodsSixty patients of American Society of Anaesthesiologists (ASA) grade I–III, aged between 18 and 70 years, scheduled for phacoemulsification cataract surgery were randomly assigned to two equal groups. Group C (control group) received 2 ml of a mixture of 2% lidocaine and 0.5% bupivacaine and Group D (dexmedetomidine group) received 2 ml of a mixture of 2% lidocaine and 0.5% bupivacaine plus dexmedetomidine (0.5 μg/kg). Onset and duration of sensory and motor block was recorded. Pain during administration of anesthesia and during surgery was graded using the verbal analogue scale and recorded. Intraocular pressure, hemodynamic, and sedation parameters were recorded before and after surgery.ResultsOnset of both sensory and motor block was significantly decreased in group D (P < 0.001, P = 0.004 respectively), and duration of sensory and motor block was more prolonged in group D than in group C (P < 0.001, P = 0.961). Pain during administration of anesthesia was significantly lower in group I compared with group II, and more patients in group I compared with group II were pain free, without a significant difference between the two groups. Intraocular pressure was significantly decreased in group D (P < 0.001). More sedation score was observed in group D (P = 0.022). Heart rate and mean arterial blood pressure were insignificantly decreased in group D more than in group C.ConclusionDexmedetomidine is a safe and effective adjuvant to subtenon block in phacoemulsification cataract surgery. 相似文献
