Purpose: To compare the effectiveness of intravitreal ranibizumab (IVR) for diabetic macular edema (DME) between eyes with and without previous vitrectomy. Procedures: We prospectively assessed the best-corrected visual acuity (BCVA) and central macular thickness (CMT) after IVR for 6 months. Results: There were no significant differences in the baseline BCVA and CMT between both groups. In the nonvitrectomized group (n = 15), the mean changes of BCVA and CMT from baseline to month 6 were significant (p < 0.01). In the vitrectomized group (n = 10), the improvement appeared to be slower, and the mean BCVA improvement was not significant (p = 0.5), although the mean CMT decrease was significant (p < 0.05). There were no significant differences in the mean changes of BCVA and CMT between both groups at 6 months. Conclusions: The difference in the effectiveness of IVR between both groups was not significant. IVR can be a treatment option even for vitrectomized DME eyes.

Purpose. To evaluate efficacy of intravitreal triamcinolone (IVT) and bevacizumab (IVB) as adjunctive treatments to panretinal photocoagulation (PRP) in proliferative diabetic retinopathy (PDR). Methods. In 60 eyes of 45 patients with PDR, PRP (PRP group), PRP with IVT (IVT group), or PRP with IVB (IVB group) was performed. Regression of new vessels (NV), changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and contrast sensitivity at 1,2, and 6 months were evaluated. Results. Initial mean numbers of active NV and BCVA were 3.45 and 67.35 in the PRP group, 4.35 and 76.65 in the IVT group, and 4.79 and 75.53 in the IVB group. At the 6-month follow-up, numbers of active NV were 2.5 (P=0.064), 1.11 (P=0.000), and 1.11 (P=0.002), and there was a mean loss of 2,6 (P=0.055), 3.9 (P=0.011), and 0.9 letters (P=0.628) in the PRP, IVT, and IVB groups, respectively. Changes in CMT in the PRP and IVT groups were not significant, but significantly increased in the IVB group (P=0.032). Contrast sensitivity remained stable in PRP and IVB groups and slightly decreased in IVT group. Conclusions. Adjunctive use of both triamcinolone and bevacizumab with PRP lead to a greater reduction of active NV than PRP alone in PDR, although no differences were seen between the two of them.

Abstract Purpose To evaluate the effectiveness of subthreshold micropulse laser as compared to intravitreal injection of ranibizumab in treatment of center involving diabetic macular oedema. Methods A total of 76 eyes of 62 patients with center involving diabetic macular oedema were divided into two groups. Group A received intravitreal injection of ranibizumab while group B received subthreshold micropulse laser with rescue intravitreal injection of ranibizumab. The change from baseline in best correscted visual acuity and central subfield thickness were compared at 3, 6, 9 and 12 months follow-up. Any adverse effects were recorded. Results Group A (n = 34 eyes) experienced a statistically significant improvement in best corrected visual acuity (from 0.32±0.16 Log MAR at baseline to 0.21±0.14 Log MAR at 12 months) (P value =0.006), with a statistically significant reduction in central subfield ghickness (from 352.06±34.34µm to 289.47±58.88 µm) (P value=0.001). Group B (n = 42 eyes), also experienced a statistically significant improvement in best corrected visual acuity (from 0.34±0.22 Log MAR at baseline to 0.13±0.31 Log MAR at 12 months) (P value=0.001), with a statistically significant reduction in central subfield thickness (from 300±47.34µm to 253.12±39.60 µm at 12 months) (P value= 0.009). The mean difference in best corrected visual acuity between the group B and group A was -0.08 Log MAR with a 95% CI ranging from -0.197 to 0.037, which supports the claim of non-inferiority between the two treatment regimens. No adverse effects from subthreshold micropulse laser were recorded in both groups. Conclusion subthreshold micropulse laser with rescue intravitreal injection of ranibizumab was non inferior to intravitreal injection of ranibizumab in treatment of center involving diabetic macular oedema as regards the mean change in best corrected visual acuity.

Key words: ranibizumab, age-related macular degeneration, central macular thickness. Research objective. To evaluate influence of treatment with vascular endothelial growth factor inhibitor, ranibizumab, for best corrected visual acuity and central macular thickness in patients with neovascular age-related macular degeneration. Materials and methods. In this retrospective study were included treatment – naive patients. Intravitreal injections were performed at Lithuanian University of Health Sciences Kaunas Clinics Eye clinic. In this study were analysed the 24-month morphological and functional outcomes of intravitreal ranibizumab injections. Best corrected visual acuity was meassured using the Snellen chart (Landolt’s rings C optotypes). Optical coherence tomography images were obtained using the spectral – domain OCT (NIDEK RS – 3000 Advance (NIDEK CO LTD, Japan). The central thickness measurements were obtained from macular thickness maps using the digital caliper tool. Results. In this study were included 88 patients. Best corrected visual acuity before treatment was 0.36 ± 0.22. The difference between visual acuity before and after first injection was 0.04 ± 0.22 (p = 0.03). Before fifth injection visual acuity was 0.41 ± 0.21, after – 0.46 ± 0.22 (p = 0.05). Central macular thickness before treatment was 297.81 ± 106.04 μm. The difference between central macular thickness before and after first injection was 85.21 ± 113.37 μm (p &lt; 0.001). Before second injection central macular thickness was 273.57 ± 87.49 μm, after – 234.51 ± 58.96 μm (p = 0.002). Before fourth injection central macular thickness was 237.20 ± 40.87 μm, after – 219.10 ± 42.26 μm (p = 0.04). The mean central macular thickness significantly decreased from 298.15 ± 104.78 to 229.08 ± 56.57 (p &lt; 0.001). In 24 month of treatment the average number of ranibizumab injections was 3.61 ± 1.55. Conclusions. Our study’s results showed that over 24 month best corrected visual acuity improvement was statistically significant after first and fifth injection. Baseline compared with last injection, there was not statistically significant difference. Central macular thickness improvement statistically significant was after first, second and fourth injection. There was statistically significant decreased baseline compared with the last injection. The mean number of ranibizumab injections was 3.61 ± 1.55 in 24 month.

Purpose To investigate the effect and the safety of intravitreal aflibercept in patients affected by choroidal neovascularization secondary to angioid streaks with a long-term follow-up. Methods Multicentre, open-label, phase IIb study (EYLEA-STRIE, EudraCT Number 2014-000986-30) involving four Italian centres (IRCCS Ospedale San Raffaele (Milano), Fondazione G.B. Bietti (Roma), Policlinico (Milano), Ospedale Luigi Sacco (Milano)). Patients with active choroidal neovascularization secondary to angioid streaks with foveal involvement were prospectively enrolled and followed for 18 months. All the patients received intravitreal 2 mg/0.05 mL aflibercept at the time of enrolment, followed by a pro-re-nata regimen for 48 weeks. Best-corrected visual acuity and central macular thickness were measured monthly. Adverse events were monitored at each visit. Results Twenty-three eyes of 20 patients were analysed. Mean number of injections per patient was 4.30 ± 1.2. At week 48, the best-corrected visual acuity was 0.42 ± 0.40 LogMAR (p = 0.6 from baseline) and 18 eyes (81.8%) featured stability within 15 letters. The central macular thickness significantly reduced (p = 0.03). Eleven ocular non-serious adverse events and two serious adverse events were observed (one case of endophthalmitis and one case of acute gastritis were reported). Conclusion Intravitreal aflibercept represents a valid option for the management of choroidal neovascularization complicating angioid streaks. Further studies with longer follow-up and different therapeutic regimens are warranted to ascertain the best control of the disease.

AimTo determine whether early vision gains predict long-term visual outcomes in the BEVORDEX randomised clinical trial of bevacizumab or dexamethasone implants for diabetic macular oedema.MethodsPost hoc analysis of 68 study eyes (77%) that completed 2 years follow-up of the BEVORDEX multicentre randomised clinical trial set in Australia (ClinicalTrials.gov identifier: NCT01298076). Study eyes from both groups were combined and stratified by visual acuity (VA) change in the first 12 weeks in to three groups: (a) suboptimal gain: <5 letters gain (includes VA loss), (b) moderate gain: 5–9 letters gain, (c) pronounced gain: ≥10 letters gain. This was correlated with VA outcome at 104 weeks taking into account treatment allocation and baseline lens status.ResultsThe change in VA in the first 12 weeks was significantly correlated with VA change at 104 weeks (p<0.001). This was independent of treatment allocation (p=0.353) and lens status at baseline (p=0.593). The change in central macular thickness at 12 weeks did not correlate with VA gain at 104 weeks (p=0.847).ConclusionShort-term visual gain at 12 weeks was strongly correlated with long-term vision improvement independent of treatment allocation or baseline lens status. Early improvement in central macular thickness was not predictive of long-term visual outcomes.Trial registration numberNCT01298076, Post-results.

Abstract Background: To evaluate the efficacy and safety of conbercept for patients with chronic central serous chorioretinopathy (CSC). Methods: A retrospective clinical study. This study included twenty-seven patients (32 eyes) who were diagnosed with chronic CSC in our hospital from November 2015 to March 2018. All the patients received intravitreal conbercept with one intravitreal injection and pro re nata (PRN). Follow-up observations occurred at 1 week and 1, 2, 3, and 6 months after initial injection. Observed indicators included best-corrected visual acuity (BCVA), central macular thickness (CMT) and presence of subretinal fluid (SRF). Results: During the 6-month follow-up, the mean number of injections required and performed was 1.50±0.67. The BCVA at the first visit, 1-week, 1-, 2-, 3- and 6-month follow-ups after the first injection was 0.44±0.26, 0.39±0.29, 0.38±0.29, 0.33±0.29, 0.31±0.30, and 0.31±0.29, respectively. The difference between the BCVA at each follow-up and the first visit was statistically significant (F=9.717, P<0.05). CMT at the first visit, 1-week, 1-, 2-, 3- and 6- month after first injection was 323.25±158.49μm, 263.78±122.52μm, 222.34±92.46μm, 195.63±69.18μm, 189.25±68.71μm, and 200.47±86.30μm, respectively. The difference between the CMT at each follow-up and the first visit was also statistically significant (F=17.072, P<0.05). Full resolution of fluid was achieved in 7 (21.9%) eyes at 1 month, 14 (43.8%) eyes at 2 months, 19 (59.4%) eyes at 3 months and 23 (71.9%) eyes at 6 months after the initial treatment of anti-VEGF injection. No severe adverse event was noted relevant to the therapy. Conclusion: Intravitreal injection of conbercept can effectively reduce the CMT and improve the BCVA in chronic CSC in a short term of 6 months.

BACKGROUND Diabetic macular oedema is a sight threatening complication of diabetic retinopathy. Vascular endothelial growth factor (VEGF) plays an important role in developing diabetic macular oedema. There are many treatment options available for diabetic macular oedema such as laser therapy, intravitreal injectable medications like anti-VEGF and steroids. This study intends to compare the efficacy and safety of intravitreal injection Ranibizumab (anti-VEGF) and Triamcinolone acetonide (steroid) in diabetic macular oedema. METHODS This is a prospective randomized study conducted among 42 patients ≥ 18 years of age with diabetic macular oedema presenting to outpatient department in a tertiary care centre in Gorakhpur, UP, conducted from November 2019 – December 2020. 42 participating patients were divided into 2 groups, A and B with 21 patients in each group. Group A treated with intravitreal injection Ranibizumab (0.05 ml ; 0.50 mg) and group B treated with intravitreal injection Triamcinolone acetonide (4 mg in 0.1 ml). All patients were followed-up at 2 week and 4 week after injection for best corrected visual acuity, intraocular pressure, foveal and para-foveal thickness. Optical coherence tomography was performed for measuring foveal and para-foveal thickness. RESULTS The mean age group being 56.48 years in group A and 58.63 years in group B with 12 male and 9 female patients in group A and 10 male and 11 female patients in group B with no dropout during study period. Both injections were equally effective in reducing foveal and para-foveal thickness and improving best corrected visual acuity. Intraocular pressure (IOP) was stable in Ranibizumab treated group but Triamcinolone treated group showed raised IOP in few patients, required anti-glaucoma medications. CONCLUSIONS Both treatment types had good efficacy in reducing foveal and para-foveal thickness and thus improving best corrected visual acuity, but intravitreal Ranibizumab is safer and well tolerated along with good efficacy in patients with diabetic macular oedema.
