PURPOSE: To evaluate the effects of posterior subtenon triamcinolone acetonide injection on refractory diabetic macular edema (DME) after intravitreal bevacizumab (IVB) injection failure. METHODS: Patients with DME and central subfield thickness (CST) >300 microm who did not respond to IVB injections were retrospectively included. Specifically, we enrolled patients who were diagnosed with refractory DME and who experienced an increase in CST after 1 to 2 IVB injections or no decrease after > or =3 consecutive IVB injections. One clinician injected 20 mg of triamcinolone acetonide into the posterior subtenon space. All patients received ophthalmic examinations at baseline and at 2, 4, and 6 months post-baseline. Examinations included Snellen visual acuity, intraocular pressure, and spectral-domain optical coherence tomography. RESULTS: Forty eyes of 34 patients were included. The average baseline CST was 476 microm. The average CST decreased to 368 microm at 2 months, 374 microm at 4 months, and 427 microm at 6 months (p < 0.001 for all results, Wilcoxon signed-rank test). The average intraocular pressure increased from 15.50 to 16.92 mmHg at 2 months but decreased to 16.30 mmHg at 4 months and 15.65 mmHg at 6 months. Logarithm of the minimum angle of resolution visual acuity improved from 0.56 to 0.50 at 2 months (p = 0.023), 0.50 at 4 months (p = 0.083), and 0.48 at 6 months (p = 0.133, Wilcoxon signed-rank test). No complications were detected. CONCLUSIONS: Posterior subtenon triamcinolone acetonide is an effective and safe treatment for reducing CST in DME refractory to IVB.

The Diabetic Retinopathy Clinical Research Network (DRCR.net) performs studies on new treatments for diabetic retinopathy. This review aims to summarise recent findings from DRCR.net studies on the treatment of diabetic macular oedema. We performed a PubMed search of articles from the DRCR.net, which included all studies pertaining to the treatment of diabetic maculopathy. The main outcome measures were retinal thickening as assessed by central subfield thickness on optical coherence tomography and improvement of visual acuity on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Findings from each study were divided into modalities of treatment, namely photocoagulation, bevacizumab, triamcinolone, ranibizumab and vitrectomy. While modified ETDRS focal/grid laser remains the standard of care, intravitreal corticosteroids or anti-vascular endothelial growth factor agents have also proven to be effective, although they come with associated side effects. The choice of treatment modality for diabetic macular oedema is a clinical judgement call, and depends on the patient's clinical history and assessment.

We present a case of ocular toxocariasis treated successfully with oral albendazole in combination with steroids. A 26-year-old male visited the authors' clinic with the chief complaint of flying flies in his right eye. The fundus photograph showed a whitish epiretinal scar, and the fluorescein angiography revealed a hypofluorescein lesion of the scar and late leakage at the margin. An elevated retinal surface and posterior acoustic shadowing of the scar were observed in the optical coherence tomography, and Toxocara IgG was positive. The patient was diagnosed with toxocariasis, and the condition was treated with albendazole (400 mg twice a day) for a month and oral triamcinolone (16 mg for 2 weeks, once a day, and then 8 mg for 1 week, once a day) from day 13 of the albendazole treatment. The lesions decreased after the treatment. Based on this study, oral albendazole combined with steroids can be a simple and effective regimen for treating ocular toxocariasis.

BACKGROUNDIntravitreal anti-vascular endothelial growth factor (anti-VEGF) drugs and corticosteroids are being widely used to treat diabetic macular edema (DME). The purpose of this study was to evaluate further the efficacy and safety of intravitreal bevacizumab (IVB) alone in comparison with intravitreal bevacizumab combined with triamcinolone acetonide (IVB/IVT) in the treatment of DME.

METHODSPertinent publications were identified through CNKI, PubMed, Medline, EMBASE, and the Cochrane Controlled Trials Register up to November 30, 2013. Two investigators independently assessed the quality of the trials, and changes in central macular thickness (CMT) and best-corrected visual acuity (BCVA) were extracted at 6 weeks and 3, 6, 12, and 24 months after the initial treatment. A meta-analysis was carried out to compare the results between the groups receiving IVB and IVB/IVT using the software RevMan 5.0.

RESULTSA total of six randomized controlled trials (RCTs) were identified and included. The meta-analysis revealed that a significant reduction of the CMT was observed at 3 months after the initial treatment in the IVB/IVT group compared to the IVB group (P = 0.001). Also, changes in CMT at 6 weeks and 6, 12, and 24 months did not vary significantly between the IVB and IVB/IVT groups (P = 0.53, 0.76, 0.34, and 0.09, respectively). Similarly, changes in BCVA at 6 weeks and 3, 6, 12, and 24 months also did not vary significantly between the two groups (P = 0.66, 0.98, 0.81, 0.07, and 0.80, respectively). The results were robust to sensitivity analyses. However, the rate of intraocular pressure (IOP) rise after intravitreal injections varied significantly between the IVB and IVB/IVT groups (P < 0.01). A publication bias was not detected by funnel plots, the Egger method, or the Begg method.

CONCLUSIONS RESULTSof this meta-analysis showed that the treatments with IVB alone and combined IVB/IVT were similarly effective in improving the visual acuity, and, to some degree; combined IVB/IVT appeared to offer a marginal advantage over IVB in decreasing CMT in patients with DME. However, the addition of IVT resulted in intraocular pressure rise in some treated patients.

This study aims at trying to establish a novel method of sterility test for injections based on biothermodynamics, in order to overcome the deficiencies of routine sterility tests such as long detecting cycle, low sensitivity and prone to misjudgments. A biothermodynamics method was adopted to rapidly detect the microorganism contamination of injections by monitoring the heat metabolism during the growth of microbe. The growth rate equal to or greater than zero and the heat power difference of P(i) and P(0) with three folds higher than the noise of baseline were chosen as indexes to study the heat change rule of microbe. In this way, the effectiveness of the new method to detect strains required by conventional sterility test or in injection samples was also investigated. Results showed that the Gram-positive bacteria, Gram-negative bacteria and fungi demanded by sterility testing methodology could be detected by biothermodynamics method within 10 hours, with the sensitivity lower than 100 CFU x mL(-1). Meanwhile, this method was successfully applied to the sterility test of Compound Yinchen injection (FFYC), Shuanghuanglian powder injection (SHL) and Compound Triamcinolone injection (TAND) which were sterilized with different degrees. Therefore, the biothermodynamics method, with advantages of fast detection and high sensitivity, could be a complementary solution for conventional sterility tests.

PURPOSE: To compare the long-term efficacy and safety of intravitreal triamcinolon with or without rescue laser therapy (intravitreal triamcinolone injection [IVTA] group), bevacizumab with or without rescue laser treatment (intravitreal bevacizumab injection [IVB] group), or a combination of both with or without rescue laser therapy (IVTA + IVB group), with standard care for patients with macular edema secondary to branch retinal vein occlusion (BRVO). METHODS: We reviewed the medical records of 151 patients treated with intravitreal injection with or without rescue laser for treatment of macular edema caused by BRVO, and who were followed up at 1, 3, 6, 12, and 24 months. During the observation period, rescue grid laser or repeated intravitreal injection with initial drug was performed if recurrence of macular edema was confirmed. Visual acuity, change in visual acuity, and intraocular pressure were compared in each phase. RESULTS: Totals of 16%, 5.6%, and 0% of participants in the three groups showed significant visual loss of more than three lines of the Snellen chart at last follow-up. The IVTA group was the least effective treatment modality, with statistical significance. The development rates of elevated intraocular pressure were similar among the groups. CONCLUSIONS: Although IVTA yielded effects similar to those of standard grid photocoagulation based on the Standard Care vs Corticosteroid for Retinal Vein Occlusion study, IVB or IVTA + IVB with or without rescue laser treatment resulted in improvement in visual acuity at 24 months after the start of treatment and was associated with few serious adverse side effects. Thus, these approaches could be useful for treating macular edema arising secondary to BRVO.
