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: This work aims to investigate real-world treatment patterns and outcomes in eyes with branch retinal vein occlusion in the antivascular endothelial growth factor (anti-VEGF) era. Methods: A retrospective, nonrandomized, comparative study was conducted on eyes diagnosed with branch retinal vein occlusion at a single tertiary center between 2009 and 2017. Medical history, treatment patterns, and visual acuity outcomes were examined. Subanalysis was performed for eyes that met the eligibility criteria for the BRAVO (Ranibizumab for the Treatment of Macular Edema Following Branch Retinal Vein Occlusion) trial. Results: A total of 315 eyes were included, of which 244 were treatment naive. In all eyes, the most common first treatment was the following: intravitreal bevacizumab (38.4%), aflibercept (15.1%), ranibizumab (8.1%), sectoral scatter laser (6.2%), and triamcinolone (3.1%). At 1 year, treatment-naive eyes had received an average of 2.43 anti-VEGF injections. During follow-up, treatment-naive eyes gained an average of 0.21 Early Treatment Diabetic Retinopathy Study lines. Forty eyes that met BRAVO trial criteria received an average of 5.05 anti-VEGF injections in the first year and gained an average of 1.83 Early Treatment Diabetic Retinopathy Study lines. Conclusions: This real-world cohort received fewer anti-VEGF injections at year 1 and experienced less improvement in visual acuity during the course of treatment than clinical trial participants. Trial-eligible patients received more injections and had greater visual gains than those who would not have been eligible for the trial.

Abstract Purpose The pathomechanism leading to retinal vein occlusion (RVO) is unclear. Mechanical compression, thrombosis, and functional contractions of veins are discussed as the reasons for the increased resistance of venous outflow. We evaluated changes in the retinal venous pressure (RVP) following intravitreal injection of anti-vascular endothelial growth factor (VEGF) agent to determine the effect on RVO-related macular edema. Methods Twenty-six patients with RVO-related macular edema (16 branch RVOs [BRVOs] and 10 central RVOs [CRVOs], age 72.5 ± 8.8 years) who visited our hospital were included in this prospective study. Visual acuity (VA), intraocular pressure (IOP), central retinal thickness (CRT) determined by macular optical coherence tomography, and RVP measured using an ophthalmodynamometer were obtained before intravitreal injection of ranibizumab (IVR) and 1 month later. Results Comparison of the BRVOs and CRVOs showed that VA was significantly improved by a single injection in BRVOs (P < 0.0001; P = 0.1087 for CRVOs), but CRT and RVP were significantly decreased without significant difference in IOP after the treatment in both groups (P < 0.0001). Conclusion The anti-VEGF treatment resulted in a significant decrease in the RVP, but the RVP remained significantly higher than the IOP. An increased RVP plays a decisive role in the formation of macula edema, and reducing it is desirable.

Purpose. Ischemic central retinal vein occlusion (CRVO) eyes are at high risk of developing neovascular glaucoma (NVG). Our purpose is to investigate the effect of anti-VEGF therapy for macular edema after CRVO on the development of neovascular glaucoma (NVG) in ischemic CRVO eyes.Methods. This is a retrospective case series of 44 eyes from 44 patients with CRVO treated with anti-VEGF therapy for macular edema. The primary outcome was the development of NVG.Results. Of the 44 eyes, 14 eyes had ischemic CRVO, and 30 eyes had nonischemic CRVO. Nonischemic eyes received a mean of 8.4 anti-VEGF doses, over mean follow-up of 24 months. One nonischemic eye (3.3%) developed NVD but not NVG. The 14 ischemic eyes received a mean of 5.6 anti-VEGF doses, with mean follow-up of 23 months. Of these 14 ischemic eyes, two eyes (14%) developed iris neovascularization and 3 eyes (21%) developed posterior neovascularization. Three of these 5 eyes with neovascularization progressed to NVG, at 19.7 months after symptom onset, on average.Conclusion. Anti-VEGF therapy for macular edema may delay, but does not prevent, the development of ocular NV in ischemic CRVO. Significant risk of NVG still exists for ischemic CRVO eyes.

Abstract Background: Most studies indicate that vitrectomy delivers sustained improvements in macular thickness. Evidence on whether acuity is improved is inconsistent. In the presence of traction vitrectomy is thought to be visually effective. In the absence of traction vitrectomy was usually performed as rescue therapy when repeated laser treatments had failed and visual improvement may not have been possible. Studies where vitrectomy was performed early in the disease showed visual benefit. All these data also predate the current gold standard anti VEGF therapy for DME and SD OCT imaging of the vitreo retinal interface. We hypothesise that adding a vitrectomy and internal limiting membrane peel to standard care intravitreal Anti-VEGF injections in the management of CIDME will result in: improved or comparable visual outcomes, fewer anti-VEGF injections and reduced costs. Methodology: VIDEO is a pragmatic stratified, single-masked, randomised, multi centre, controlled, feasibility trial with 12 months follow up. Stratification will be based in the presence or absence of OCT evident vitreomacular traction or epiretinal membrane. The primary outcome is Distance best corrected visual acuity. Secondary outcomes are Number of injections, Rate of completed follow, Rate of recruitment, Central macular thickness on OCT, Area under the curve of CMT, Area under curve of BCVA, Rate of loss of 15 or more letters from baseline, Rate of Rescue therapy, Rate of cataract surgery, Rate of complications. Recruitment target is 100 patients with 1:1 randomisation to the treatment arm (vitrectomy + standard care) or control arm (standard care) with 12 month follow up. Standard care is treat and extend intravitreal anti-VEGF injections. Main inclusion criteria: -Patient over 18 years of age -Patient has capacity to give informed consent -Patient has not previously been enrolled in this study in regards to their other eye - Symptomatic visual loss attributable to diabetic macular oedema for less than one year -Patient has a formal diagnosis of Diabetes Mellitus -Patient has an HbA1c test (a blood test that looks at long term diabetic control) performed within the past 2 months. Ophthalmic criteria: -Symptomatic visual loss attributable to DMO for less than one year. -Best corrected visual acuity of better than 35 ETDRS letters on formal testing -Central macular thickness greater than 350 microns. Discussion: Outcomes should inform the effect size with which to inform the design of a definitive randomised control trial ISRCTN Registry ISRCTN59902040 18.12.20 retrospectively registered http://www.isrctn.com/ISRCTN59902040

Tractional retinal detachment is an uncommon complication of intravitreal anti-vascular endothelial growth factor (VEGF) injection wherein the drug triggers tractional retinal detachment as a result of fibrovascular membrane contraction. We present a case of a 42-year-old hypertensive woman diagnosed with chronic central retinal vein occlusion on both eyes. The right eye had total retinal detachment and neovascular glaucoma, while the left eye had retinal neovascularisation. Panretinal photocoagulation and intravitreal anti-VEGF injection was started on the left eye. However, she was lost to follow-up. She returned 4 months later with extensive tractional retinal detachment involving the macula on the left eye. She subsequently underwent vitrectomy with endolaser and silicone oil tamponade on the left eye. The anti-VEGF ‘crunch’ results from regression of fibrovascular proliferation with a concurrent increase in fibrosis, resulting in worsening retinal traction. With the widespread use of anti-VEGF agents, ophthalmologists need to be aware of this vision-threatening complication.

Background/aimsClinical trials suggest anti-vascular endothelial growth factor is more effective than intravitreal dexamethasone as treatment for macular oedema secondary to branch retinal vein occlusion. This study asks if ‘real world’ data from a larger and more diverse population, followed for a longer period, also support this conclusion.MethodsData collected to support routine care at 27 NHS (National Health Service) Trusts between February 2002 and September 2017 contained 5661 treatment-naive patients with a single mode of treatment for macular oedema secondary to branch retinal vein occlusion and no history of cataract surgery either during or recently preceding the treatment. Number of treatment visits and change in visual acuity from baseline was plotted for three treatment groups (anti-vascular endothelial growth factor (anti-VEGF), intravitreal dexamethasone, macular laser) for up to 3 years.ResultsMean baseline visual acuity was 57.1/53.1/62.3 letters in the anti-VEGF/dexamethasone/macular laser groups, respectively. This changed to 66.72 (+9.6)/57.6 (+4.5)/63.2 (+0.9) at 12 months. Adequate numbers allowed analysis at 18 months for all groups (66.6 (+9.5)/56.1 (+3.0)/60.8 (-1.5)) and for anti-VEGF at 36 months (68.0, +10.9) Mean number of treatments were 5.1/1.5/1.2 at 12 months, 5.9/1.7/1.2 at 18 months for all three groups and 10.3 at 36 months for anti-VEGF.ConclusionsVisual acuity improvements were higher and more sustained with anti-VEGF. Higher treatment burden occurred with anti-VEGF but this reduced over 36 months. Patients with better vision at baseline than those in the clinical trials maintained high levels of vision with both anti-VEGF and dexamethasone.

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.
