Aflibercept is the most recently approved vascular endothelial growth factor (anti-VEGF) inhibitor for the management of diabetic macular edema and diabetic retinopathy. The purpose of this article is to review the efficacy and safety of aflibercept in the management of diabetic eye complications and to describe its place in therapy. Anti-VEGF agents have been noted in clinical trials to be superior to laser photocoagulation, the standard therapy ( P < .0001, P ≤ .0085, respectively). Aflibercept has been comparatively studied with other anti-VEGF agents, namely, bevacizumab and ranibizumab, and noted to be equally efficacious and safe in patients with mild visual acuity loss ( P > .50). However, in the treatment of patients with diabetic macular edema having moderate to severe visual acuity loss, aflibercept outperformed the other 2 anti-VEGF agents (aflibercept vs bevacizumab, P < .001; aflibercept vs ranibizumab, P = .003). However, additional studies are needed to fully appreciate the long-term safety and efficacy of aflibercept and the anti-VEGF therapy class.

Purpose. To demonstrate the results of treatment with the use of a VEGF inhibitor (anti-VEGF) in a clinical case of severe edema of the macular and paramacular regions against the background of toxocaral uveitis in remission. Material and methods. This article presents a clinical case of an 11-year-old female patient with increasing severe macular edema with neovascularization, which appeared against the background of toxocaral uveitis in remission. In connection with the progression of the disease, the patient was injected intravitreally with an inhibitor of vascular endothelial growth factor aflibercept. Results. At discharge, the patient showed positive dynamics in the form of an increase in visual acuity in the left eye from 0.04 to 0.07. According to the results of ophthalmoscopy and OCT of the left eye, a decrease in the area of exudation is determined, which confirms the effectiveness of the treatment. Conclusion. The description of this case can be provided as information about the possibility of using a VEGF inhibitor for exudative processes of the macular region of various etiologies in the absence of the effectiveness of conservative treatment methods. Key words: toxocariasis, uveitis, macular edema, aflibercept, anti-VEGF, OCT.

Background: Pro re nata (PRN) regimen using anti-vascular endothelial growth factor (VEGF) agent is popular for the treatment of diabetic macular edema (DME). We investigated the influence of waiting time (WT) and interval between the date of recurrence of edema and re-injection on treatment efficacy. Methods: This retrospective study conducted at 7 sites in Japan enrolled patients who received intravitreal injection of ranibizumab (IVR) and aflibercept (IVA) in 1+PRN regimen. Enrolled patients were divided into 2 groups: prompt group (less than 1 week) and deferred group (3 weeks or more). Central retinal thickness (CRT) and best corrected visual acuity (BCVA) were measured every month for 1 year. Results: CRT in the deferred group was significantly higher than that in the prompt group at 2, 5, 6, 7, and 12 months (p < 0.05). BCVA in the prompt group was significantly better than that in the deferred group at 7, 10, and 12 months (p < 0.05). Conclusion: The prompt group was superior in anatomical and functional improvement of DME in anti-VEGF therapy than the deferred group. Our data suggests that shorter WT is recommended for better visual prognosis in the treatment for DME.

Diabetic macular edema (DME) is the main cause of visual impairment in diabetic patients. Intravitreal anti-vascular endothelial growth factor (VEGF) therapy is considered the first-line treatment option in the management of DME with corticosteroids used as second-line therapy. The DRCR.net Protocol U study was a Phase II trial that sought to compare the combination of a steroid and anti-VEGF therapy to anti-VEGF monotherapy regarding visual acuity and anatomic outcomes. This review highlights the strengths, weaknesses, and clinical implications of this study.

Potential Biomarker

Purpose. Ellipsoid zone (EZ) integrity is identified as a potential biomarker for therapy surveillance and outcome prediction of visual acuity (VA). However, only a few studies report long-term results of over 1 year of clinical and anatomical changes in patients with diabetic macular edema (DME). This study is aimed at describing the long-term VA and anatomical outcomes in spectral domain optical coherence tomography (OCT) (relative ellipsoid zone reflectivity ratio, central macular thickness, and volume) in patients with DME treated with antivascular endothelial growth factor (anti-VEGF) therapy. Furthermore, we studied the correlation between EZ integrity and changes in visual acuity. Methods. 71 eyes of 71 patients were included in this retrospective study. Clinical characteristics were reviewed yearly. OCT data were assessed at baseline and after 1, 3, and 5 years. EZ parameters were quantified automatically. OCT parameters and visual outcome were correlated and analyzed in multivariable regression models. Results. EZ reflectivity ratio correlated with functional outcome in DME patients from baseline to fifth year at all time points (for all p < 0.05 ). EZ reflectivity improved the most in the first year of treatment (0.68 to 0.75; p < 0.05 ) and declined gradually until year 5 of therapy (0.71; compared to baseline p > 0.05 ). Similarly, best VA was achieved after 1 year (0.40 logarithm of the minimum angle of resolution (logMAR) to 0.28 logMAR; p < 0.001 ) and declined gradually until year 5. Final VA in year 5 was comparable to baseline (0.45 logMAR, compared to baseline p > 0.05 ). Together with baseline VA, baseline EZ parameters did predict VA outcome after 1 year ( p < 0.05 ). Concordantly, VA and EZ parameters from year 1 were associated with VA outcome in year 2. Conclusion. This study described the long-term course of EZ changes during anti-VEGF treatment in DME patients. In addition, our results underlined the potential of EZ parameters as novel OCT biomarkers for prediction of VA outcomes during therapy.

Purpose: The study aimed to describe our initial experience with the use of anti vascular endothelial growth factors (anti-VEGFs) in the treatment of retinal diseases. Methods: The case records of all patients who had received at least 3 doses of intravitreal anti- VEGF injections between January 2012 to December 2016 were reviewed. Information culled from the data was age, sex, indications for treatment, type of injection, presenting visual acuity, post injection visual acuity, systemic and ocular co morbidities. Results were analyzed using Statistical Package for Social Sciences (SPSS) 20.0 for Windows statistical software Results: A total of 190 injections were given during the study period, to 58 eyes of 50 patients. Twenty-eight females (56.00%) and twenty-two males (44.00%) were seen with a mean age of 59.6± 11.66. Bevacizumab was the most frequently administered anti- VEGF, 142 (74.74%) while only 48(25.26%) injections of Ranibizumab were given. Three eyes had both bevacizumab and ranibizumab (1.58%). Retinal vein occlusion 61(32.11%) was the commonest indication for the injections followed by diabetic macular edema 43(22.63%) and proliferative diabetic retinopathy 42(22.11%). Others were neovascular age related macular degeneration, neovascular glaucoma, vitreous hemorrhage, myopic choroidal neovascularization and cystoid macular edema. There was an association between age and disease, (p = 0.001). There was an improvement in visual acuity after intervention in cases with retinal vein occlusion and diabetic macular edema, and this was statistically significant. Hypertension was the commonest systemic disorder in this series 81(42.36%) and the supero-temporal quadrant 131(68.95%) was the most preferred position to administer the injection. Floaters was the commonest complication seen. Conclusion: Anti VEGFs have become an invaluable tool in the management of a number of retinal diseases in our center. However, the cost implications are a hindrance to an increased uptake of this form of treatment. Cheaper alternative preparations should be made available to encourage the uptake. Government in developing countries should be encouraged to bear the health burden of the old aged pensioner (OAP).

Purpose: To evaluate long-term visual and anatomical outcomes of anti–vascular endothelial growth factor (VEGF) therapy for macular edema (ME) secondary to retinal vein occlusion (RVO) in routine clinical practice. Methods: Patients with ME secondary to hemi-RVO (HRVO), central RVO (CRVO), or branch RVO (BRVO) after initiating anti-VEGF therapy were followed for at least 36 months. Main outcomes were change in best visual acuity (BVA) and mean absolute change in central subfield thickness (CST) at 12, 24, 36, and 48 months. Results: Patients with BRVO showed significant increases in BVA that were maintained after 12, 24, 36, and 48 months (+11.03, +12.06, +10.71, and +9.26 letters, respectively; P < .05). CST significantly decreased after 12, 24, 36, and 48 months (−83.51, −67.93, −97.52, −127.85 µm, respectively; P < .05). In patients with CRVO/HRVO, significant improvements in BVA were seen at 12 and 24 months (+9.39 and +8.54 letters, respectively; P = .023). At 36 and 48 months, the visual gain was not significant (+2.64 and +3.42 letters, respectively; P > .05). For CST changes, there were significant decreases at 12, 24, and 36 months (−146.23, −149.54, and −166.44 µm, respectively; P < .05). At 48 months (−97.66 µm, P = .130), changes in CST were not significant. Conclusions: In routine clinical practice, visual and anatomical benefits of anti-VEGF agents in patients with BRVO were sustained at 36 and 48 months. For patients with CRVO/HRVO, anatomical improvements were maintained for 36, but not 48 months, while visual improvements were no longer maintained by 36 months.

Abstract Purpose: To study long-term clinical outcomes in patients with submacular hemorrhage (SMH) and/or vitreous hemorrhage (VH) associated with neovascular age-related macular degeneration (nAMD), who received pars plana vitrectomy (PPV) followed by anti-vascular endothelial growth factor (VEGF) therapy.Methods: In this retrospective case series, 25 eyes with SMH and/or VH associated with nAMD were treated by PPV and followed for at least 24 months. When exudative changes were unresolved or recurred after PPV, additional intravitreal anti-VEGF therapy was given. Results:Mean best-corrected visual acuity (BCVA) of all patients improved significantly at 1, 3, 6, 12, 18 and 24 months (P<0.01) post-PPV and at the final visit (P<0.05). Mean BCVA of 13 eyes with anti-VEGF therapy improved significantly at 1 (P<0.05), 3, 6, 12 (P<0.01), 18 and 24 months (P<0.05), while 12 eyes without anti-VEGF therapy improved at 1, 3 and 6 months (P<0.05) only. Average duration from initial PPV to anti-VEGF therapy initiation was 7.54±9.9 months. Five of 13 eyes (38.5%) with anti-VEGF therapy maintained dry macula for more than 1 year after the last injection. Conclusions:　In patients with SMH and VH caused by nAMD, administering intravitreal anti-VEGF therapy when exudative changes are unresolved or recur after PPV maintains improved visual acuity long term.
