Abstract
PURPOSE To evaluate anterior flare intensity (AFI) and central retinal thickness (CRT) values after intravitreal injection of aflibercept (IVA), ranibizumab (IVR), or triamcinolone acetonide (IVTA) in patients with diabetic macular edema (DME). METHODS This research was conducted as a prospective study for patients with DME. Patients with phakia received either IVA or IVR, whereas patients with pseudophakia received IVA, IVR, or IVTA. AFI and CRT were measured using a laser flare meter and spectral domain optical coherence tomography, respectively, at days 0, 1, 7, 30, and 90. RESULTS Forty patients with phakia and 60 patients with pseudophakia were enrolled this study. In the IVTA group, AFI of pseudophakic eyes was significantly decreased at days 1 (p = 0.0487), 7 (p = 0.0201), and 30 (p = 0.0211). In the IVA group, AFI of phakic eyes was transiently increased at day 1 (p = 0.0078) and returned to baseline at day 7, whereas no significant change was observed in AFI of pseudophakic eyes. In the IVR group, there was no significant change in AFI regardless of phakic condition. All groups showed significant reduction in CRT at day 7 and later. CONCLUSION DME improved after treatment by IVTA, IVR, or IVA, whereas AFI was reduced only in eyes treated with IVTA. The temporal profiles of AFI are likely related to differences in the pharmacological properties of the drugs.

Abstract
PURPOSE Our purpose was to compare the impact in diabetic macula edema (DME) of two intravitreal drugs (0.5 mg ranibizumab vs. 8 mg triamcinolone) on changes in retinal morphology in spectral-domain optical coherence tomography (SD OCT) images, color fundus photography (CF) and fluorescein angiography (FA) images during a 1-year follow-up. METHODS Post hoc analysis was conducted of morphologic characteristics in OCT, FA and CF images of eyes with a center involving DME that were included in a prospective double-masked randomized trial. Eligible patients were divided at random into two groups receiving either pro re nata treatment with 0.5 mg ranibizumab or 8 mg triamcinolone after a fixed loading dose. OCT and CF images were acquired at monthly visits and FA images every three months. RESULTS Twenty-five eyes of 25 patients (ranibizumab: n = 10; triamcinolone: n = 15) were included in this study. Patients treated with ranibizumab showed better visual acuity results after 12 months than patients receiving triamcinolone (p = 0.015) although edema reduction was similar (p = 0.426) in both groups. The initial effect on macular edema shedding after a single ranibizumab injection could be amplified with the following two injections of the loading dose. After a single injection of triamcinolone the beneficial initial effect on the macula edema faded within 3 months. Subretinal fluid and INL cystoid spaces diminished early in the course of treatment while fluid accumulation in the ONL seemed to be more persistent in both treatment arms. In FA, the area of leakage diminished significantly in both treatment arms. After repeated injections the morphologic OCT and FA characteristics of the treatment arms converged. CONCLUSIONS Despite the higher dosage of triamcinolone, both therapies were safe and effective for treating diabetic macular edema. Fluid accumulation in the INL and subretinal space was more responsive to therapy than fluid accumulation in the ONL. Clinicaltrials.gov : NCT00682539.

Abstract
BACKGROUND Facial dermatitis can result from various conditions, some of which are of a chronic and relapsing nature. The use of topical corticosteroid therapy may lead to additional adverse effects. OBJECTIVE To compare the efficacy of moisturizer containing 4-t-butylcyclohexanol, which acts as a sensitivity regulator, and licochalcone A, an anti-inflammatory agent from the licorice plant Glycyrrhiza inflata, with that of 0.02% triamcinolone acetonide (TA) for the treatment of facial dermatitis. METHODS This was a randomized, prospective, investigator-blinded study. Eighty participants with mild to moderate facial dermatitis were randomly treated with either the test facial moisturizer or 0.02% TA twice daily for the first 2 weeks. For the subsequent 2 weeks, all patients used only the test moisturizer. Clinical assessment by investigators, bioengineering measurements, patients' subjective evaluation, and clinical photography were performed at baseline, week 2, and week 4. RESULTS Both treatments showed a statistically significant improvement with regard to physician clinical assessment, skin hydration, transepidermal water loss, and patient-assessed visual analog scale after 2 and 4 weeks of treatment compared with baseline. The test facial moisturizer produced better skin hydration than TCS. The improvement in TEWL after 4 weeks of using the test moisturizer was comparable with 2-week treatment with 0.02% TA cream. However, subjective evaluation by patients indicated that TA more rapidly improved sensation sensitivity. CONCLUSION The test facial moisturizer was slower than 0.02% TA in improving facial dermatitis, but showed greater benefit in erythema control and skin hydration.

Abstract
PURPOSE To compare the results of intravitreal bevacizumab (IVB) injection alone or in combination with intravitreal 1 mg triamcinolone acetonide (IVT) in center-involved diabetic macular edema. METHODS In this randomized clinical trial study, ninety-two eyes of 46 patients with bilateral center-involved diabetic macular edema and no previous treatment were included in the study. One eye of each patient was randomly assigned to 1.25 mg of IVB injection or combination of 1.25 IVB and 1 mg IVT. Evaluation of best-corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure (IOP) and grading of lens opacity was conducted at baseline, and weeks 2, 4, 6, 8, 12 and 24 after treatment. Retreatment was performed at a 6-week interval whenever indicated based on CMT. RESULTS Between the groups, BCVA changes were not statistically different until 24-week follow-up (P > 0.05), but at 24 weeks after treatment, BCVA improvement was significantly better in IVB group (P = 0.049). Significant CMT reduction was observed in each group along the follow-up period (P = 0.001). The mean CMT reduction was more significant in combination (IVB + IVT) group at 2 weeks of follow-up (P < 0.001), but CMT changes were not significant between the groups at weeks 12th and 24th after injection. Overall, retreatment was applied for 59 eyes up to 24 weeks (33 in the IVB group, 26 in the IVB + IVT group). Among patients with 2 or more injections, number of injections was significantly lower in IVB + IVT group (P = 0.043). Three eyes within IVB + IVT group developed IOP rise beyond 21 mmHg, which were controlled with topical anti-glaucoma medications within 1 week. Changes in lens opacity were not significant between two groups. CONCLUSION Eyes treated with IVB plus 1 mg IVT injections had more significant reduction in CMT in early post-injection, but this effect was transient. Although after 24 weeks visual acuity improvement was better in IVB group, combination therapy may decrease the number of injections. Combining 1 mg of intravitreal triamcinolone with bevacizumab was not accompanied with significant side effects.

Abstract
BACKGROUND/AIMS: To investigate whether intravitreal injection of triamcinolone acetonide (IVTA) combined with vitrectomy prevents postoperative inflammation in patients with vitreous haemorrhage (VH) due to proliferative diabetic retinopathy (PDR). METHODS This prospective, multicentre, randomised study conducted at seven sites in Japan enrolled patients diagnosed as having VH following PDR. Patients underwent vitrectomy with (IVTA+VIT group) or without (VIT group) IVTA at the end of the surgery. Anterior flare intensity (AFI), central retinal thickness (CRT), best-corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured before and at 3 days, 1 week, 1, 3 and 6 months after surgery and compared. RESULTS Number of patients who completed 6 months of follow-up was 40 and 41 in VIT group and IVTA+VIT group, respectively. AFI was significantly higher in the VIT group than in the IVTA+VIT group at 3 days (P=0.033), 1 week (P=0.019) and 1 month (P=0.037). There were no significant differences in CRT, BCVA and IOP between the groups through the observational periods. In the cases with macular oedema >350 µm of CRT at 3 days, CRT was significantly lower in the IVTA+VIT group than in the VIT group at 1 month (P=0.041). CONCLUSIONS IVTA combined with vitrectomy and cataract surgery contributed to inhibit the postoperative inflammation in patients with VH due to PDR. The effect of IVTA in the reduction of diabetic macular oedema may be limited to the early stage after surgery. TRIAL REGISTRATION NUMBER UMIN000020376, Post-results.

Abstract
PURPOSE The purpose of this study was to compare the changes in the aqueous cytokine levels after intravitreal bevacizumab with those after combined intravitreal bevacizumab and subtenon triamcinolone injection in diabetic macular edema (DME). METHODS This study examined 24 eyes of 23 patients with DME. Each patient with DME received randomly either an intravitreal injection of bevacizumab (IVBe) or IVBe with a subtenon triamcinolone injection (IVBe + STTA). Best corrected visual acuity and foveal thickness were evaluated and aqueous samples were obtained before and 4 weeks after the injection. The aqueous concentrations of interleukin (IL)-6, IL-8, interferon-induced protein (IP)-10, monocyte chemotactic protein (MCP)-1, platelet-derived growth factor (PDGF)-AA, and vascular endothelial growth factor (VEGF) were measured using a multiplex bead assay. RESULTS After the injection, the foveal thickness decreased more in the IVBe + STTA group than in the IVBe group (P = 0.042). The MCP-1, PDGF-AA, and VEGF levels decreased significantly in the IVBe + STTA group (p = 0.013, p = 0.004 and p = 0.018 respectively), but only the VEGF level decreased in the IVBe group (p = 0.001). IL-8 was significantly increased in the IVBe + STTA group (p = 0.003) but the changes in the VEGF levels were smaller than in the IVBe group (p = 0.025). CONCLUSION Intravitreal bevacizumab and subtenon triamcinolone injection reduces the VEGF, MCP-1 and PDGF-AA levels and increases the IL-8 level in the plural cytokine profiles of patients with DME, which might explain the limited therapeutic effect of combination therapy.

Abstract
PURPOSE To evaluate detailed changes in retinal layer thickness in spectral-domain optical coherence tomography (SD-OCT) images during a 1-year follow-up of patients treated for diabetic macula oedema (DME). METHODS Post hoc analysis of retinal layer thickness changes applying the automated layer segmentation of SD-OCT images in eyes with DME that were randomly assigned to receive pro re nata (PRN) treatment with either 0.5 mg ranibizumab or 8 mg triamcinolone. In each patient, seven retinal layers were segmented in 49 scans covering a 20° × 20° area of the macula at baseline and after 1 year of treatment. Changes in individual layer thickness were correlated with visual acuity (VA) and compared between treatment arms. RESULTS Twenty-five patients (seven female, 60.2 ± 15.1 years) were evaluated. Thickness decrease of retinal nerve fibre layer (RNFL) was associated with a gain in VA over 12 months (r > 0.54; p < 0.05). Decrease in ganglion cell layer (GCL) and GCL+IPL thickness pooled for nasal Early Treatment of Diabetic Retinopathy Study (ETDRS) subfields correlated with VA as follows: ranibizumab r = 0.74 (GCL) and r = 0.63 (GCL+IPL); and triamcinolone r = 0.45 (GCL) and r = 0.46 (GCL+IPL). CONCLUSION In DME therapy, reduction in RNFL thickness may have a considerable impact on retinal function, unrelated to the type of pharmacological treatment. Precise morphologic quantification of neurosensory layers by SD OCT offers new insight into disease pathology and therapeutic targets.

Abstract
BACKGROUND AND OBJECTIVE To study anatomic changes in the suprachoroidal space (SCS) following suprachoroidal injection of CLS-TA, triamcinolone acetonide injectable suspension. PATIENTS AND METHODS Eyes with diabetic macular edema receiving CLS-TA were imaged serially using anterior segment spectral-domain optical coherence tomography to examine the SCS. RESULTS At the final imaging session, the SCS was not significantly different in study eyes (n = 14; 8.4 μm) compared to fellow eyes (n = 10; 8.1 μm; P = .698). Two eyes were imaged immediately before and 30 minutes after suprachoroidal injections; in these eyes, mean suprachoroidal width increased significantly following CLS-TA injection, 9.9 μm to 75.1 μm (P < .001), and subsequently returned to 14.9 μm 1 month after the final injection (P = .221). CONCLUSION Suprachoroidal CLS-TA injection caused a measurable increase in the SCS, which returned to preinjection levels by 1 month following injection with no apparent lasting impact on SCS anatomy.

Abstract
BACKGROUND Keloids and hypertrophic scars are due to overgrowth of dermal collagen following trauma to the skin that usually cause major physical, psychological and cosmetic problems. METHODS In this randomized controlled trial, with a paired design, 50 patients with 2 or more keloids were included. In the control group (50 lesions), intralesional triamcinolone acetonide (40mg/mL) was injected at three-week intervals for a total of 18weeks. In the other group (50 lesions), lesions were treated by verapamil (2.5mg/mL) with the same therapeutic sessions. Scar evaluation at each stage and at the end of 3months follow up was done by serial photographic records as well as by Vancouver Scar Scale (VSS). RESULTS Mean zero VSS scores were achieved with only triamcinolone in respect of scar height (week 15th) and pliability (week 15th). No therapeutic event (parameter=0) or significant improvement was seen in verapamil group. CONCLUSION Our results did not support verapamil's capability in treatment of keloid nor hypertrophic scars.

Abstract
BACKGROUND Diabetic macular edema (DME) is responsible for three-quarters of vision-loss cases in diabetic eye disease. In most cases, early treatment by laser photocoagulation can only stabilize vision. Glucocorticoids have been used as a local pharmacological treatment in DME when the inflammation seems to have a pathological background. OBJECTIVES The aim of the study was to establish the effectiveness and safety of intravitreal triamcinolone injections in the treatment of DME. MATERIAL AND METHODS Twenty mg intravitreal injections of triamcinole acetonide (IVTA) were applied to 110 DME patients after ineffective laserphotocoagulation or as an initial treatment. Best corrected visual acuity (BCVA) for distant and near vision, central retinal thickness and intraocular pressure (IOP) were analyzed before and after the treatment at intervals of 1 week, 1 month, 3 months and 6 months. The measurements were continued in cases of repeated IVTA. RESULTS Statistically significant improvements were observed in BCVA in near and distant vision, as well as a decrease in central retinal thickness after all time-intervals following IVTA. BCVA in distant vision was not significantly improved after repeated IVTA. IOP increases were observed 1 week, 1 and 3 months after IVTA, but not at 6 months after IVTA. No sight-threatening side effects of IVTA were observed. CONCLUSIONS IVTA is useful in stabilizing DME progression, although its therapeutic effect may be timelimited.
