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: 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.

Abstract Background Subthreshold photocoagulation is one of the therapeutic options for treating diabetic macular edema, and have characteristic advantages, which are the lack of chorioretinal damage and the repeatability of the treatment. However, the effect of subthreshold photocoagulation is thought to be minimal among these options. In this study, we retrospectively examined the efficacy of repeated subthreshold photocoagulation for persistent diabetic macular edema after vitrectomy with peeling of the internal limiting membrane. Methods We enrolled ten consecutive eyes of eight patients who underwent monthly Endpoint Management™ (EpM) six times for diabetic macular edema that persisted for more than 3 months after vitrectomy with internal limiting membrane peeling for epiretinal membrane, and classified according to the interval between vitrectomy and initial EpM (Group A: within 6 months, Group B: beyond 6 months). Two type of retinal thickness (central macular thickness and macular thickness within 3mm diameter of the fovea) were measured monthly using optical coherence tomography. Results Mean intervals between vitrectomy and initial EpM were 4.0 ± 1.2 months (range 3–6 months) in Group A (six eyes of five patients) and 17.3 ± 7.5 months (range 10–27 months) in Group B (four eyes of four patients). No other treatments were performed between vitrectomy and initial EpM in Group A, while triamcinolone acetonide injection in the sub-Tenon’s capsule was performed in two eyes in Group B (one eye was injected thrice, the other eye received a single injection). Improvement rates of mean central macular thickness after 6 months were 18.2% in all eyes, 10.8% in Group A, and 28.7% in Group B, and improvement rates of mean macular thickness within 3mm diameter of the fovea after 6 months were 8.5% in all eyes, 4.1% in Group A, and 15.3% in Group B. Conclusions Monthly EpM treatment was efficacious against persistent diabetic macular edema after internal limiting membrane peeling. In particular, the efficacy was greater in eyes in which the initial EpM was performed more than 6 months after vitrectomy. Furthermore, residual efficacy of triamcinolone acetonide, which was injected at the end of vitrectomy, might have contributed to the results.

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.

Objective: To explore the clinical efficacy of intravitreal injection of conbercept in combination with retinal laser photocoagulation in the treatment of diabetic macular edema. Methods: Ninety patients with diabetic macular edema were selected and grouped into an observation group and a control group using random number table, 45 patients (45 eyes) each group. The control group was given retinal laser photocoagulation, while the observation group was given intravitreal injection of Conbercept on the basis of panretinal photocoagulation. The Best Corrected Visual Acuity (BCVA), thickness of retinal nerve fibre layer (RNFL) and macular thickness were measured through relevant examinations before and after treatment. The intraocular pressures of patients in the two groups were evaluated, and moreover the complications were recorded. Results: The RNFL thickness and macular thickness of the two groups had no statistically significant differences before treatment (P>0.05) and decreased significantly after treatment; the decrease amplitude of the observation group was significantly larger than that of the control group (P<0.05). The BCVA of both groups significantly increased in the 1st, 2nd and 4th week after treatment (P<0.05); the increase amplitude of BCVA of the observation group was more significant than that of the control group at different time points after treatment (P<0.05). The intraocular pressure of the observation group was not significantly different with that of the control group in the 1st, 2nd and 4th week after treatment (P>0.05). There were no severe eye complications and systemic adverse reactions in both groups in the process of follow up. Conclusion: Intravitreal injection of conbercept in combination with retinal laser photocoagulation performs better in improving the BCVA and central macular thickness of patients with diabetic macular edema compared to retinal laser photocoagulation and has high safety. doi: https://doi.org/10.12669/pjms.35.6.512 How to cite this:Meng W, Li R, Xie X.

Aims: To investigate the changes in vision-related quality of life after a loading dose of three consecutive intravitreal ranibizumab (IVR) injections in patients with unilateral diabetic macular edema (DME). Materials and Methods: Fifty-two eyes of 52 patients who received IVR injections in only one eye with DME were included in our study. The following characteristics of the patients were recorded: gender, education status, marital status, work status, presence of chronic disease. The changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT) were evaluated at baseline (before treatment) and 1 month after the third intravitreal injection (after treatment). Patients were administered the Turkish form of the National Eye Institute 25-Item Visual Functions Questionnaire (NEI VFQ-25 TR). The quality of life scores assessed by the NEI VFQ-25 TR, the BCVA, intraocular pressure (IOP), and CMT measurements were compared at baseline (before treatment) and 1 month after the third intravitreal injection (after treatment). Results: We enrolled 52 patients (25 females, 27 males) in our study; mean age was 64.35 ± 9.26 years. After treatment, BCVA improved significantly (p = 0.001), and macular thickness decreased significantly (p < 0.001). All NEI VFQ-25 TR subscale scores were significantly higher after treatment (p < 0.05). However, no significant correlation was found between the change in BCVA and CMT and the change in NEI VFQ-25 TR subscale and composite scores. The increase in near activities scores was significantly higher in males (p = 0.020) and in the retired group (p = 0.022). There were no significant differences in the changes in NEI VFQ-25 TR subscale and composite scores in relation to educational status. Discussion: Significant improvements in BCVA, macular edema, and vision-related quality of life were found in DME patients who received IVR injections with a loading dose, as shown by the NEI VFQ-25 TR. Interestingly, a significant improvement in quality of life was observed even though the patients could see well with the fellow eye. In conclusion, the NEI VFQ-25 TR is a useful scale to evaluate the changes in visual function and psychosocial characteristics of DME patients after treatment.
