Introduction: Macula edema consists in one of the most common causes of visual impairment. Objective: To evaluate the safety and efficacy of continuous release of 0.7 mg dexamethasone (using implantable device) for treatment of macular edema. Methods: Cross-sectional observational study of 16 patients treated with 0.7 mg dexamethasone intraocular implant. Visual acuity, intraocular pressure and central macular thickness were recorded at baseline, 1-month and 3-month follow-up. Results: 15 eyes of 13 patients were included. Most eyes (n=9) improve visual acuity from baseline at 1-month follow-up; this improvement persisted through 3-monyh follow-up in six eyes. The central macular thickness decreased in the majority of the subjects at 1-month (n=12) and at 3-month (n=10) follow-up. Three eyes presented with elevated intraocular pressure. Conclusion: Dexamethasone implant can both reduce the risk of vision loss and improve anatomical features of macular edema due to several pathologies studied. This implant may be used safely and should be considered a therapeutic option to Brazilian Public Health System.

BACKGROUND: Diabetic macular edema is a significant cause of vision loss, and some patients do not respond optimally to existing treatments. This study compared the response of intractable diabetic macular edema to intravitreal injection of two anti-VEGF drugs, bevacizumab and pegaptanib, both in combination with dexamethasone. METHODS: A retrospective chart review was conducted to examine patients from an ophthalmology practice in one year with diabetic macular edema (DME), recurrent or persistent, after focal laser or intravitreal bevacizumab. Patients received bevacizumab/dexamethasone or pegaptanib/dexamethasone. Outcome measures were improvement in best corrected visual activity (converted to LogMAR) and central macular thickness (CRT). Data on adverse effects also were collected. RESULTS: The bevacizumab/dexamethasone group included 25 eyes which had pre-treatment LogMAR = 0.69 ± 0.49 (mean ± SD) and CRT = 419 ± 131. Post-treatment LogMAR was 0.70 ± 0.48 and CRT = 377 ± 107. The pegaptanib/dexamethasone group included 14 eyes; pretreatment LogMAR = 0.80 ± 0.55 and CRT = 520 ± 108. Post-treatment LogMAR was 0.77 ± 0.49 and CRT = 46 4 ± 106. Neither treatment had a significant effect on visual acuity. Both groups experienced a significant decrease in CRT over time (p = 0.006). The pegaptanib/ dexamethasone group had higher CRT at all times (p = 0.020), but the trend in CRT decrease was not different between the two groups. Intraocular pressure increased in both groups (p = 0.038). No other adverse effects were reported. CONCLUSIONS: Neither bevacizumab/dexamethasone or pegaptanib/dexamethasone significantly improved visual acuity in intractable DME, but both decreased central macular thickness. Differences in outcome measures between the two treatment groups were not significant. The only adverse effect seen was a small increase in intraocular pressure.

Introduction: Diabetic Macular Edema (DME) is a manifestation of diabetic retinopathy and is the most common cause of vision loss in diabetics. The incidence of DME has a tendency to increase, concomitant with the prevalence of diabetes globally by more than 50% from 2000 to 2030. This study aims to evaluate the proportion of central macular thickness (CMT) improvement and visual acuity in DME patients treated with intravitreal bevacizumab (IVB) injection. Methods: This study is a retrospective descriptive study. The study was conducted in the Department of Ophthalmology at RSUP Cipto Mangunkusumo (RSCM) Jakarta. Data were obtained from the medical records of all diabetic retinopathy patients with macular edema who were treated with IVB at RSCM Kirana Vitreoretina Polyclinic on January – December 2017. Results: Of the 44 subjects, improvement in best corrected visual acuity (BCVA) occurred in 24 (54.54%) subjects at the first-month evaluation and 19 (43.18%) subjects at the third-month evaluation. CMT decreased in 37 (84.41%) subjects at the first-month evaluation and 35 (81.81%) subjects at the third-month evaluation. Conclusion: Visual acuity improvement and central macular thickness reduction 3 months after IVB injection. These results strengthen IVB injection to be an alternative to adjuvant therapy in DME.   Keywords: Diabetic Macular Edema, Intravitreal Bevacizumab Injection

Patients having high refractive errors (spherical equivalent of > ± 7.5D) and visual acuity worse than +1.2 or better than +0.2 on log MAR were excluded. Central macular edema was measured in μm on OCT and visual acuity was documentedusing Log MAR chart. These values were documented before and at 01 month after injection with intravitrealBevacizumab. Wilcoxon Signed rank test was used to evaluate the difference in VA beforeand after the anti-VEGF injection. Difference in visual acuity and macular edema (central) was observed,analyzed and represented in p value. P value was considered statistically significant if it was less than 0.01%.Results: Mean age of patients was 52.61 ± 1.3. Vision improved from 0.90 ± 0.02 to 0.84 ± 0.02 on log MARchart. The change was statistically significant with p value < 0.001. Central macular thickness reduced from 328 ±14 to 283 ± 10.6 μm on OCT after intravitreal anti-VEGF, with significant p value < 0.001.Conclusion: A 45 μm reduction in central macular thickness was associated with 0.1 Log MAR unit improvementin visual acuity after intravitreal Bevacizumab in diabetic macular edema.

INTRODUCTION: Diabetic retionopathy is a microangilpathy. The present study was done to investigate results of Intravitreal Triamcinolone Acetonide injection for the treatment diffuse diabetic macular edema. MATERIAL AND METHODS: The study included 40 eyes of 40 patients with clinically significant diffuse diabetic macular edema. Eyes were diagnosed with diabetic macular edema according to Early Treatment Diabetic Retinopathy Study guidelines. An Intravitreal injection of Triamcinolone Acetonide at the dose of 4 mg/0.2 ml was administered. Best corrected visual acuity was measured as the logarithm of the minimum angle of resolution (logMAR) and snellen vision drum and size of macular edema (hard exudates) was obtained by slit lamp biomicroscopy using +90 D Volk lens at each visit. Intraocular pressure (IOP) and other complications related with steroid and injection related complications were also evaluated. Subsequently patients were followed up on 1st day, 2nd week and 3rd month. RESULTS: All patients were completed second follow up at 3 months. The mean size of macular edema, which obtained at 3 months postoperatively, was significantly different from the baseline measurement from 1.4125 to 0.9474 DD. Mean visual acuity improved significantly from baseline at 3 months of follow up was 0.7421 LogMAR (≈ 6/30 in Snellen chart). Eleven eyes developed intraocular pressure higher than 21 mmHg at 2nd week postoperatively. Other drug and injection related complications were not developed. Increased IOP were controlled with anti glaucoma drugs. CONCLUSIONS: Intravitreal Triamcinolone was a promising therapeutic method for diabetic macular edema. TriamcinoloneAcetonide effectively reduces size of macular edema and improves visual acuity in the short term.Journal of Universal College of Medical Sciences (2015) Vol.03 No.02 Issue 10 Page: 30-34

Diabetic macular edema (DME) is a significant cause of diabetic retinopathy and a major cause of vision loss. In this study, we aimed to evaluate and compare the efficacy of two injectable drugs; intravitreal Aflibercept and intravitreal Ranibizumab for the treatment of DME of the eyes. A retrospective chart review was conducted for patients diagnosed with DME from March 2014 to January 2019 who received either intravitreal Aflibercept or intravitreal Ranibizumab injection. A total of 57 eyes were included, of which 19 eyes were treated with intravitreal Ranibizumab injection, and 38 eyes were treated with intravitreal Aflibercept injection; all eyes were examined for 3 months. Two outcomes were assessed in this study, namely; visual acuity (VA) and central macular thickness (CMT). The mean age in the Ranibizumab group was 61.1±9.5 vs 64.3±10.2 in the Aflibercept group with no significant difference (p-value=0.25). The ratio of improvement in visual acuity (VA) in the Ranibizumab group was 68.4% vs 44.7% in the Aflibercept group; (p-value=0.038) which demonstrates the superiority of Ranibizumab over Aflibercept concerning visual acuity result. However, there is no statistically significant difference between the ratio of improvement in central macular thickness (CMT) results in both groups; (p-value=1.00). In fact, the ratio of improvement in CMT in both groups was the same 78.9% for both the groups. The pre and post results demonstrated improvement in post-procedural for CMT among both the groups but only Ranibizumab group showed VA improvement post-procedural. Through this study, we concluded that both injectable drugs improve visual acuity (VA) and decrease central macular thickness (CMT) in eyes with DME. However, Ranibizumab is superior in improving visual acuity compared to Aflibercept. Further comparative effectiveness trials between Aflibercept and Ranibizumab are still warranted.

Purpose To evaluate the effect of intravitreal triamcinolone acetonide on visual acuity and macular thickness using optical coherence tomography (OCT) in macular edema associated with various retinal vascular disorders. Methods This prospective nonrandomized clinical interventional study included 81 eyes (76 patients) comprised of Group I, 57 eyes (51 patients) with diabetic macular edema; Group II, 10 eyes (10 patients) with branch retinal vein occlusion; and Group III, 13 eyes (13 patients) with central retinal vein occlusion. All eyes received an intravitreal injection of 4 mg triamcinolone acetonide (with the solvent) in the operation theater under sterile conditions. Results Mean preinjection central macular thickness was 531.84±132 μm in Group I, 458.4±149 μm in Group II, and 750.81±148 μm in Group III. All groups showed a statistically significant decrease in mean central macular thickness at 1 month (300.7±119 μM in Group I, 218.2±99 μm in Group II, and 210.5 ±56 μm in Group III) and 3 months (253.19±109 μm in Group I, 187±47 μm in Group II, and 182±50 μm in Group III) after injection (p<0.05). Mean follow-up was 22±2.4 weeks. Mean visual acuity increased in all three groups (preoperative visual acuity in Group I, 1.2±0.4 logMAR units; Group II, 1.24±0.5 logMAR units; Group III, 1.1 ±0.4 logMAR units; 1 month postinjection in Group I, 0.88±0.3 logMAR units; Group II, 0.67±0.3 logMAR units; Group III, 0.86±0.4 logMAR units; 3 months postinjection in Group I, 0.84±0.4 logMAR units; Group II, 0.59±0.3 logMAR units; Group III, 0.82±0.5 logMAR units) (p<0.05). Forty-one eyes completed 6 months and 20 eyes completed 9 months follow-up. Twelve of 20 (41%) eyes in Group I, 2/6 (33%) eyes in Group II, 3/6 (50%) eyes in Group III, and 8/15 (53%) eyes in Group I, 1/3 (33%) eyes in Group II, and 2/2 (100%) eyes in Group III developed recurrence of macular edema with worsening of visual acuity at 6 and 9 months, respectively. Thirty-three (40.7%) eyes developed IOP elevation (at least one reading > 24 mmHg). One eye developed infective endophthalmitis. Conclusions Intravitreal injection of triamcinolone acetonide may be considered as an effective treatment for reducing macular thickening due to diffuse diabetic macular edema, venous occlusion associated macular edema, and may result in increase in visual acuity at least in the short term. Further follow-up and analysis is required to demonstrate its long-term efficacy.

Purpose. To observe the changes in metamorphopsia, visual acuity, and central macular thickness (CMT) in patients undergoing vitrectomy for idiopathic epiretinal membranes (iERM); all of which were preoperatively stratified into 4 stages according to the anatomical structure of the macula seen on the optical coherence tomography (OCT) b-scan images. Methods. A total of 108 eyes of 106 patients were included. We evaluated and classified the severity of each preoperative ERM based on OCT. Changes in the best-corrected visual acuity (BCVA), metamorphopsia, and CMT were studied by comparing the pre- and postoperative measurements. The follow-up time was at least 6 months. Results. There were 41 eyes at stage 2, 35 at stage 3, 32 at stage 4, and none at stage 1. BCVA and metamorphopsia significantly improved at the final visit in all patients (P<0.01). However, comparing the pre- and postoperative measurements at each stage, only the BCVA and CMT improved significantly for all stages (P<0.001). For stages 2 and 3 ERMs, the horizontal (MH) and vertical (MV) metamorphopsia scores decreased significantly after surgery (P<0.05). No significant difference was found in either MH or MV for stage 4 ERMs (P both >0.05). The preoperative BCVA, MH, and CMT had significant difference among the three stages (P<0.05). Similarly, the postoperative values in the three variables mentioned above also had significant difference among the three stages (P<0.05). For stage 2 ERMs, the baseline MH and MV were positively correlated with the baseline CMT. The MH and MV at the final follow-up also presented a significant positive correlation with the baseline CMT. For stage 3 ERMs, only the baseline MV showed significant correlation with the CMT. Conclusion. Categorization of the preoperative ERMs is a useful method to predict the postoperative improvement in metamorphopsia, which would aid in surgical decisions for patients with ERMs.

Intravitreal Triamcinolone

Diabetic macular oedema is still a significant cause of vision drop in the diabetic patient with no definitive regime for treatment. This study was on the result of effects of intravitreal injection of (2mg) triamcinolone on central macular thickness measured by OCT, visual acuity and intraocular pressure in pseudophakic eyes with diabetic macular oedema as a primary treatment line followed in six months. This study is a prospective, interventional case study series. It was on patients who received intravitreal injection of Triamcinolone in a single dose of ( 2 mg/0. 05 ml). Central macular thickness by OCT, visual acuity, and intraocular pressure was measured pre-injection and 1,3,6 months after injection. This study was performed in Iraq, Baghdad, Ibn Al-Haitham Teaching Eye Hospital from October 2014 to July 2015. Results showed 25 eyes received intravitreal injection of Triamcinolone Acetoniod with pre-injection central macular thickness 597.9+98.02 µm, visual acuity 1.096+0.61 Log MAR and intraocular pressure of 16.5+ 2.53 mmHg. After six months of follow up on central macular thickness 341.6+163.1 µm, visual acuity was 0.63 + 0.40 Log MAR and IOP was 18. 04+ 5. 63mmHg. This study suggests that intravitreal injection of Triamcinolone in a dose 2mg / 0. 05ml improves both anatomical and visual outcome in 21 eyes (84%) out of 25 pseudophakic eyes with diabetic macular oedema during first six months after injection and an increase in intraocular pressure in 2 eyes (8%). The intraocular pressure was despite the use of anti-glaucoma medications during this period.
