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.

Purpose: To evaluate the change in visual acuity in relation to decrease in central macular thickness,after a single dose of intravitreal Bevacizumab injection.Study Design: Quasi experimental study.Place and Duration of Study: Punjab Rangers Teaching Hospital, Lahore, from January 2019 to June 2019.Material and Methods: 70 eyes with diabetic macular edema were included in the study. 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.

Purpose To assess visual and optical coherence tomography–derived anatomical outcomes of treatment with intravitreal aflibercept (Eylea®) for diabetic macular oedema in patients switched from intravitreal ranibizumab (Lucentis®). Design Retrospective, cohort study. Participants Ninety eyes (of 67 patients) receiving intravitreal anti–vascular endothelial growth factor therapy were included. Methods This is a retrospective, real-life, cohort study. Each patient had visual acuity measurements and optical coherence tomography scans performed at baseline and 12 months after the first injection of aflibercept was given. Main Outcome Measures We measured visual acuities in Early Treatment Diabetic Retinopathy Study letters, central foveal thickness and macular volume at baseline and at 12 months after the first aflibercept injection was given. Results Ninety switched eyes were included in this study. The mean (standard deviation) visual acuity was 63 (15.78) Early Treatment Diabetic Retinopathy Study letters. At baseline, the mean (standard deviation) central foveal thickness was 417.7 (158.4) μm and the mean macular volume was 9.96 (2.44) mm3. Mean change in visual acuity was +4 Early Treatment Diabetic Retinopathy Study letters (p = 0.0053). The mean change in macular volume was −1.53 mm 3 in SW group (p = 0.21), while the change in central foveal thickness was −136.8 μm (p = 0.69). Conclusion There was a significant improvement in visual acuity and in anatomical outcomes in the switched group at 12 months after commencing treatment with aflibercept for diabetic macular oedema.

Purpose: The purpose of the study is to describe visual and anatomic outcomes of 5774nm micropulse laser photocoagulation in eyes with either treatment-naïve or refractory diabetic macular edema (DME) at 3 months. Methods: This was a prospective case series that recruited 23 consecutive patients (33 eyes) with center-involved DME that was either treatment-naïve or had not responded to prior treatment. Micropulse therapy was performed with the Easy Ret 577 (Quantel Medical, Cournon d’Auvergne, France) diode laser in a high-density manner in eyes with treatment-naïve or refractory DME. The primary outcome was the change of best-corrected visual acuity (BCVA; logMAR) at 1 and 3 months. Secondary outcomes were changes in the central macular thickness (CMT), thickness area, macular volume, and macular capillary leakage at 1 and 3 months. Results: There were no significant changes in BCVA at 3 months, with mean ± standard deviation (SD) of −0.08 ± 0.01 ( p = 0.228) and + 0.01 ± 0.01 ( p = 0.969) for treatment-naïve and refractory groups, respectively. The change in CMT at 3 months was statistically but not clinically significant in the treatment-naïve group only (mean ± SD; –30 ± 130 µm; p = 0.011). The macular volume and area thickness change were not statistically significant ( p = 0.173 and p = 0.148 for macular volume and area thickness, respectively) in the treatment-naïve group. There was no difference concerning the leakage area in both groups. No adverse events were reported. Conclusion: We concluded that micropulse 577nm laser therapy maintained the visual acuity and macular thickness at 3 months in both treatment-naïve and refractory DME.

AbstractThis retrospective study evaluated the association of hyperreflective foci (HRF) with treatment response in diabetic macular oedema (DME) after anti-vascular endothelial growth factor (VEGF) therapy. The medical records, including of ophthalmologic examinations and optical coherence tomography (OCT) images, of 106 patients with DME treated with either intravitreal ranibizumab or aflibercept were reviewed. The correlations between best-corrected visual acuity (BCVA) changes and HRF along with other OCT biomarkers were analysed. The mean logMAR BCVA improved from 0.696 to 0.461 after an average of 6.2 injections in 1 year under real-world conditions. Greater visual-acuity gain was noted in patients with a greater number of HRF in the outer retina at baseline (p = 0.037), along with other factors such as poor baseline vision (p < 0.001), absence of epiretinal membrane (p = 0.048), and presence of subretinal fluid at baseline (p = 0.001). The number of HRF after treatment was correlated with the presence of hard exudate (p < 0.001) and baseline haemoglobin A1C (p = 0.001). Patients with proliferative diabetic retinopathy had greater HRF reduction after treatment (p = 0.018). The number of HRF in the outer retina, in addition to other baseline OCT biomarkers, could be used to predict the treatment response in DME after anti-VEGF treatment.
