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.

Purpose. To determine changes in central subfield (CSF) macular thickness and best corrected visual acuity (BCVA) following single session, multispot panretinal photocoagulation (PRP).Methods. Forty eyes of 33 patients with newly diagnosed proliferative diabetic retinopathy were treated with single session, 20-millisecond, multispot PRP. Changes in central macular thickness and BCVA at 4- and 12-week follow-up were compared to baseline measurements.Results. Each eye received a mean (SD) of 2,750 (686.7) laser spots. At 4-week follow-up, there was a statistically significant 24.0 μm increase in mean CSF thickness (P=0.001), with a 17.4 μm increase from baseline at 12-week follow-up (P=0.002). Mean logMAR BCVA increased by 0.05 logMAR units (P=0.03) at 4-week follow-up. At 12-week follow-up, BCVA had almost returned to normal with only an increase of 0.02 logMAR units compared to baseline (P=0.39). Macular edema occurred in 2 eyes (5%) at 12-week follow-up.Conclusions. Macular thickening occurs following single session, 20-millisecond, multispot PRP, with a corresponding, mild change in BCVA. However, the incidence of macular edema appears to be low in these patients. Single session, 20-millisecond, multispot PRP appears to be a safe treatment for patients with proliferative diabetic retinopathy.

We evaluated the effect of intravitreal bevacizumab (IVB) injection before pars plana vitrectomy (PPV) on intravitreal hemorrhage (VH) during and after vitrectomy for postoperative the first day and the first month in pseudophakic patients with proliferative diabetic retinopathy (PDR). This retrospective study was performed on 44 eyes of 44 patients who underwent vitrectomy for PDR. Patients were divided into PPV (n = 22 eyes) and PPV + IVB (n = 22 eyes) groups. Injection of bevacizumab (1.25 mg/0.05 mL) was performed 3 days before vitrectomy. Outcomes of visual acuity as well as intraoperative and postoperative VH were compared between the two groups. One month after surgery, visual acuity improved in PPV and PPV + IVB groups ( P = 0.005, P = 0.006), respectively. There was no difference between the two groups in best corrected visual acuity at baseline and after vitrectomy ( P = 0.71). Intraoperative bleeding into the vitreous was recorded in 14 (63.6%) cases in the PPV group and in 7 (31.8%) cases in the PPV + IVB group. The first month, intravitreal hemorrhage was recorded in six patients in the PPV group and in two patients in the PPV + IVB group ( P = 0.03). The mean pre-postoperative central macular thickness was similar in both groups. Intravitreal injection of IVB before vitrectomy decreased the rate of VH at the time of surgery and at the first postoperative month in patients with PDR.

Introduction: To report the 10 - year rate of vitrectomies and the associated factors in people with proliferative diabetic retinopathy (PDR) from a multicentric cohort of people with diabetes mellitus. Methods: Ten centres in India with established vitreoretinal services for over 10 years were invited to provide long-term data on PDR. People with Type 1 or 2 diabetes with a clinical diagnosis of active PDR in one or both eyes were included. Baseline data collected included age, sex, duration of diabetes, source of referral and best-corrected visual acuity and diabetic retinopathy status in both eyes. Available follow-up data included the numbers of panretinal photocoagulation (PRP) sessions, cataract surgery, treatment of diabetic macular edema, use of anti- vascular endothelial growth factor therapy, vitrectomy with or without retinal surgeries over 10 years. Results: Over 10 years, 89 % needed supplemental PRP after initial complete PRP. One – third required retinal surgery, 16 % needed intravitreal injection. Men (74.5%) had significant higher risk for vitreous surgery. Of the group with low risk PDR, 56.8% did not require vitreoretinal surgery, p <0.001. Of the patients who underwent cataract surgery and had intravitreal anti-VEGF injections, 78.5% and 28.2% needed subsequent vitreous surgery (VR), p=0.006 and <0.0001 respectively. Independent predictors of need for vitreo-retinal surgery included those who underwent cataract surgery and those with poor baseline visual acuity (logMAR). Eyes at lower risk for VR surgery included the eyes previously treated with PRP and low-risk PDR at baseline. Conclusion: Despite initial ‘complete’ PRP, one third of our study cohort needed vitrectomies over 10 years, highlighting that these patients require regular follow-up for a long period of time.

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.

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.

Objective: To determine the visual outcome in Diabetic Macular Edema patients after 3rd Avastin injections attending a tertiary eye care hospital. Materials and methods: This was a cross sectional study with Non probability convenient sampling technique. The study was carried out at Diabetic clinic of Al-Ibrahim Eye Hospital, Isra Postgraduate Institute of Ophthalmology, Karachi-Pakistan. Ethical approval was taken from the institutional review board of Institute. Data collection were done retrospectively from January 2017 to June 2019. Data were retrieved for DME patients who have completed three follow-ups with Avastin injection. Inclusion Criteria were patients with age 30 to 60 years, Patient with PDR and NPDR with diabetic macular edema after 3rd injection. Data Analysis was done using SPSS version 23.0. Results: A total of 40 eyes of 40 patients were included in this study after getting information from the record sheet. Analysis were done in 30 eyes of 30 patients because 10 patients were missed their follow-up due to certain reason which were observed from record sheet. Mean age of patients was found to be 41.25±10.24.Pre-operative Avastin injection best corrected visual acuity (BCVA) was noticed by using Log MAR without glasses was 0.49 and with glasses was 0.40. Post-operative best corrected visual acuity Log MAR without glasses 0.51 and with glasses 0.42 after Avastin injection. Improvement of visual acuity was classified as Improved, worsen and Stable. There were 22 (73.33%) patients observed with improvement in visual acuity, 5 (16.66%) patients retained their vision stable and only 3 (10%) patients worsen their visual acuity after all three Avastin injections. Conclusion: The most common cause of diabetic macular edema is non-proliferative diabetic retinopathy and proliferative Diabetic Retinopathy. The Intravitreal injection play vital role, the timely treatment would improve prognosis of visual outcomes in Diabetic macular edema. So the study significantly shows the improvement in best corrected visual acuity before and after three visits.
