Abstract
AIM: The aim of this study was to evaluate and compare microperimetry changes in patients with clinically significant diabetic macular edema secondary to diabetes mellitus, following intravitreal injections of bevacizumab or triamcinolone during a follow-up of 1 year after treatment. MATERIALS AND METHODS 30 patients with clinically significant macular edema were randomized into two groups of 15 patients each. One group initially received three intravitreal injections of 2.5 mg bevacizumab at monthly intervals. The other received a single injection of 8 mg of triamcinolone followed by two sham interventions at monthly intervals. Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were measured. Macular function was documented by microperimetry at baseline, 3, 6, 9 months and at the last visit of each patient. RESULTS In the bevacizumab group, the mean differential light threshold (±standard deviation) under therapy improved significantly from 8.40 (± 3.8) dB to 12.8 (±4.3) dB at the 12-month follow-up visit (p ≤ .05), whereas in the triamcinolone group it increased from 8.0 (± 2.4) dB at baseline to 9.3 (±3.6) dB at the last visit without reaching statistical significance (p > .05). The mean differential light thresholds between the two groups were not statistically significant at baseline or the last visit (p > .05). In the bevacizumab group, the improvement (slope) in mean differential light threshold was significantly superior to the Triamcinolone group (Estimate = 0.588, p ≤ .05). CONCLUSION Central macular function as measured by microperimetry in patients with acute DME improved in addition to anatomical restoration after intravitreal bevacizumab and triamcinolone injection. In our clinical study, the measures of the variables in patients receiving bevacizumab were superior to those receiving triamcinolone throughout the one-year observation period.

Abstract
AIM: To report the 6-month results of a clinical trial that compared intravitreous bevacizumab (BVB) 1.25 mg versus triamcinolone acetonide (TA) 4 mg when administered as an adjunct during cataract surgery to patients with diabetic macular oedema (DMO). METHODS Prospective, double-masked, single-centre (Royal Victorian Eye and Ear Hospital, Melbourne) clinical trial. Patients with visually significant cataract and centre-involving DMO (either current or prior) were randomised (1: 1) to receive either intravitreous BVB 1.25 mg or TA 4 mg at the time of cataract surgery and if required at review. Main outcome measures were changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT) from baseline to the 6-month time point of this 12-month study. RESULTS 61 eyes of 58 patients were enrolled. At baseline, both groups were similar in terms of BCVA and CMT (p>0.2). At 6 months, there was no significant difference in vision between the groups, with mean letter gain of +21.4 (95% CI +14.5 to +28.4) in the TA group and +17.3 (95% CI +12.1 to +22.6) in the BVB group (p=0.35). The TA group had a significant sustained anatomical improvement at 6 months, with a reduction in CMT (-51.4 µm; 95% CI -98.2 to -4.7) compared with thickening in the BVB group (+15.6 µm; 95% CI -26.4 to +57.7, p=0.04). CONCLUSIONS When given as an adjunct to cataract surgery, both TA and BVB improved visual outcomes at 6 months postoperatively. However, only TA resulted in sustained improvement in CMT, with the majority not requiring any further treatment postoperatively.

Abstract
The effect of triamcinolone acetonide (TA) on the peripheral retinochoroidal thickness was determined after pars plana vitrectomy (PPV) with scatter photocoagulation in eyes with proliferative diabetic retinopathy. The peripheral retinochoroidal thickness was measured at 5 mm from the limbus in the four quadrants using anterior segment optical coherence tomography before, and 3 days, and 1 and 2 weeks after the surgery. The total peripheral thickness was significantly thicker than the baseline thickness after PPV alone (P < 0.001; 18 eyes), PPV combined with intravitreal TA injection (IVTA; P = 0.011; 19 eyes), and PPV combined with sub-tenon TA injection (STTA; P = 0001; 23 eyes). The total peripheral thickness in the PPV group at 3 days after surgery was significantly thicker than that of the PPV + IVTA (P = 0.015) and of the PPV + STTA groups (P = 0.016). Multiple linear regression analyses showed that the injection of TA by the two routes and the number of photocoagulation burns were significantly correlated with the total peripheral thicknesses at 3 days after the surgery. The results indicate that the PPV with large number of intraoperative scatter photocoagulation burns caused an increase in the total peripheral thickness and an administration of either IVTA and STTA can reduced the degree of thickening.

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 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 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
PURPOSE To compare long-term vision and anatomic effects of ranibizumab with prompt or deferred laser vs laser or triamcinolone + laser with very deferred ranibizumab in diabetic macular edema (DME). DESIGN Randomized clinical trial. METHODS Eight hundred and twenty-eight study eyes (558 [67%] completed the 5-year visit), at 52 sites, with visual acuity 20/32 to 20/320 and DME involving the central macula were randomly assigned to intravitreous ranibizumab (0.5 mg) with either (1) prompt or (2) deferred laser; (3) sham injection + prompt laser; or (4) intravitreous triamcinolone (4 mg) + prompt laser. The latter 2 groups could initiate ranibizumab as early as 74 weeks from baseline, for persistent DME with vision impairment. The main outcome measures were visual acuity, optical coherence central subfield thickness, and number of injections through 5 years. RESULTS At 5 years mean (± standard deviation) change in Early Treatment Diabetic Retinopathy Study visual acuity letter scores from baseline in the ranibizumab + deferred laser (N = 111), ranibizumab + prompt laser (N = 124), laser/very deferred ranibizumab (N = 198), and triamcinolone + laser/very deferred ranibizumab (N = 125) groups were 10 ± 13, 8 ± 13, 5 ± 14, and 7 ± 14, respectively. The difference (95% confidence interval) in mean change between ranibizumab + deferred laser and laser/very deferred ranibizumab and triamcinolone + laser/very deferred ranibizumab was 4.4 (1.2-7.6, P = .001) and 2.8 (-0.9 to 6.5, P = .067), respectively, at 5 years. CONCLUSIONS Recognizing limitations of follow-up available at 5 years, eyes receiving initial ranibizumab therapy for center-involving DME likely have better long-term vision improvements than eyes managed with laser or triamcinolone + laser followed by very deferred ranibizumab for persistent thickening and vision impairment.

Abstract
BACKGROUND To compare visual and anatomical outcomes between intravitreous bevacizumab (BVB, Avastin) and triamcinolone (TA, Triesence) when administered at the time of cataract surgery in patients with diabetic macular oedema (DME). DESIGN Prospective, single-masked, randomized clinical trial at The Royal Victorian Eye and Ear Hospital, Melbourne. PARTICIPANTS Patients with clinically significant cataract and either centre-involving DME or DME treated within the previous 24 months. METHODS Participants were randomized 1:1 to receive intravitreous BVB 1.25 mg or TA 4 mg during cataract surgery, and at subsequent review if required over 6 months. MAIN OUTCOME MEASURES Change in central macular thickness (CMT) and best corrected visual acuity at 6 months. RESULTS Forty-one patients (mean age 66.4 years, 73.2% male) were recruited. Visual acuity and CMT were similar between groups at baseline (P > 0.2).After six months, both groups gained vision (mean +21.4 letters in TA group P < 0.0001, +12.5 letters in BVB, P = 0.002), with no significant difference between groups (P = 0.085). In addition, 60.9% of eyes receiving TA achieved a VA of ≥6/12 compared to 73.3% in the BVB group (P = 0.501). However, only TA was associated with a sustained reduction in CMT (-43.8-µm reduction TA vs. +37.3-µm increase BVB, P = 0.006 over 6 months). Following surgery, additional injections were required in 70.6% of participants in the BVB group, compared to 16.7% in the TA group (P < 0.0001). Three patients in the TA group experienced a rise of IOP over 21 mmHg (12.5%) during the 6-month follow-up; BVB had no cases (P = 0.130). There were no cases of endophthalmitis in either group. CONCLUSIONS When administered at the time of cataract surgery in patients with DME, at 6 months both TA and BVB improve visual acuity; however, only TA results in a sustained reduction in CMT. Further follow-up will determine whether this translates into better long-term visual outcomes in the TA group.

Journal of glaucoma. 2015;(2):111-6
Abstract
PURPOSE To compare the efficacy of fixed combinations of dorzolamide-timolol (FCDT) and brimonidine-timolol (FCBT) in patients with intraocular pressure (IOP) elevations after intravitreal triamcinolone acetonide (IVTA) injections. MATERIALS AND METHODS This was a prospective, randomized, open-label study. Patients who received IVTA injections due to diffuse diabetic macular edema and who had an IOP of 24 mm Hg or higher after IVTA treatment were included. They were randomized to receive either FCBT or FCDT twice daily. Follow-up visits were scheduled on week 4 and 12 weeks after starting the study medication. At all follow-up visits, IOP was measured with Goldmann applanation tonometry. The primary outcome measure was mean IOP, the secondary outcome was reduction in mean IOP at 4 and 12 weeks compared with postinjection values. RESULTS Sixty patients were randomized in 1:1 ratio. The FCBT and FCDT groups were similar in terms of age, sex, and preinjection IOP (P>0.05 for all). Mean postinjection IOP was 31.95±7.39 and 29.83±5.17 mm Hg in FCBT and FCDT groups, respectively (P=0.239). After 4 weeks, mean IOP was 17.05±3.61 mm Hg in FCBT and 18.93±3.30 mm Hg in FCDT groups (P=0.063). After 12 weeks, mean IOP in the FCBT and FCDT study groups was 16.35±2.70 and 18.43±2.82 mm Hg, respectively (P=0.012). Both fixed combinations significantly reduced IOP in comparison with the postinjection values (P<0.05). Mean reduction in IOP after 4 weeks were 14.90±7.28 mm Hg in FCBT and 10.90±4.83 mm Hg in FCDT groups (P=0.024); after 12 weeks, these values were 15.60±7.77 and 11.40±5.89 mm Hg in FCBT and FCDT groups, respectively (P=0.035). CONCLUSIONS Both FCBT and FCDT are effective in controlling IOP elevations after IVTA injections. The results of this study suggest that FCBT is superior to FCDT in reducing IOP and provides better IOP control after IVTA injections.

Bhayana, S, Sood, S, Narang, S, Sethi, NK
International ophthalmology. 2015;(4):519-25
Abstract
The aim of the study was to compare intravitreal bevacizumab (IVB) and posterior subtenon triamcinolone (PST) as an adjunct to laser treatment in diffuse diabetic macular edema (Diffuse DME). Prospective-randomized control trial of 30 eyes of 30 diabetic patients having Diffuse DME with maximum retinal thickness (MRT) was more than or equal to 350 µm. The subjects were randomly allocated into two groups. Group A (12 eyes) received IVB and group B received PST (18 patients) before laser treatment. Grid laser treatment was done when the MRT decreased to less than 350 µm. OCT thickness-guided repeat injections were given if required. The patients had minimum follow-up of 6 months. At 6-month follow-up, the two groups were compared for (1) Maximum change in visual acuity letter score using logMAR chart (2) Reduction in MRT on OCT. The mean logMAR visual acuity at baseline was 0.63 ± 0.45 (0-1.6) in group A and was 0.76 ± 0.38 (0.2-1.3) in group B. The mean logMAR visual acuity at 6 month in group A was 0.34 ± 0.21 (0-0.6) and in group B was 0.64 ± 0.37 (0.3-1.3). The mean visual acuity at last follow-up was significantly better in group A than group B (p = 0.02). The mean change in MRT in Group A and Group B was 177.8 ± 85.64 and 156.07 ± 102.86, respectively, which was significantly better than the baseline in both the groups and was comparable in both groups. The study provides evidence to support the use of IVB over PST in diffuse diabetic macular edema.
