67 ± 30.45). No intubation or resuscitation was needed. Four children complained of nausea and two needed an additional dose of intravenous ondansetron due to vomiting in the post-operative period. Incidence of postoperative nausea and vomiting was not affected by age, duration of surgery or dose of ketamine used (P > 0.05). There was no correlation between increase in pulse and dose of ketamine.
Combined ketamine and regional anesthesia is a safe and effective alternative to administer anesthesia in a child during ocular surgeries.

The aims of this study were to evaluate the effects of decorin (DCN) in rat oxygen-induced retinopathy (OIR) model and to compare the results with those of bevacizumab.
Twenty-eight newborn Sprague-Dawley rats were randomly divided into four groups. Group I (control) normoxia plus intraperitoneal (ip) normal saline (NS), Group II (sham) OIR plus ip NS, Group III (DCN) OIR plus ip 0.1 mg/kg DCN, and Group IV (bevacizumab) OIR plus ip 2.5 mg/kg bevacizumab. The OIR model was induced by cycling the oxygen concentration between 50% and 10% every 24 h for 14 days following their birth. In all groups, injections were administered on postnatal day (PD) 15. All animals were sacrificed and their right eyes were enucleated on PD 18. The nuclei of neovascular endothelial cells on the vitreal side of the inner limiting membrane were counted, and vascular endothelial growth factor (VEGF) and tumor necrosis factor-alpha (TNF)-α immunoreactivity were detected in histopathological and immunohistochemical examinations. Ondel were comparable to the effects of bevacizumab.
A sub-population of patients with diabetic macular edema (DME) responds less effectively to off-label use of Bevacizumab. Approval of Aflibercept for DME has offered Bevacizumab nonresponders an alternative therapeutic option. selleck screening library Herein, we investigate the anatomical and functional changes associated with Aflibercept treatment in Bevacizumab nonresponders with chronic DME in a Canadian setting.
A retrospective study of eyes with persistent DME that were switched to Aflibercept due to nonresponse following ≥6 consecutive monthly Bevacizumab injections was performed. Anatomical and functional changes and the predictors of response were assessed using patients' characteristics prior to receiving their first (baseline) and seventh consecutive Aflibercept injections (follow-up).
Twenty-four eyes were included, with a mean age of 63.9 ± 10.7 years, an average of 16.8 ± 8.5 Bevacizumab injections prior to switching to Aflibercept, and mean follow-up duration of 11.8 ± 1.7 months following switching to Afliberceptr CST, and better glycemic control at baseline.
The aim of this study was to present the outcomes of the 2018 and 2020 Vitreo-retinal Society of India (VRSI) biosimilars of anti-vascular endothelial growth factor (VEGF) (VIBE) surveys.
An online survey of members of VRSI was conducted in July 2018 and January 2020 regarding their practice-patterns on anti-VEGF biosimilars pertaining to safety, efficacy, pricing, and need for enhanced clinical trials before regulatory approval.
In 2018, 112 VRSI members participated, whereas in 2020, 98 society members participated. In both surveys, majority of respondents were aware of biosimilars (96%, 2018 vs. 100%, 2020; P = 0.9) and felt that approval of biosimilar drugs should be made more stringent with larger clinical trials (89%, 2018 vs. 91%, 2020; P = 0.93). An increase in use of ranibizumab-biosimilar (41%, 2018 to 56%, 2020; P = 0.2) and a simultaneous significant decline in use of bevacizumab-biosimilar (9%, 2018 to 2%, 2020; P = 0.04) was noted from 2018 to 2020. From 2018 to 2020, the proportion of resl that Indian vitreoretinal specialists are familiar with anti-VEGF biosimilars. There was a progressive trend favoring ranibizumab-biosimilar over bevacizumab-biosimilar. One-third of the participants deem the current price of ranibizumab-biosimilar as appropriate to replace Avastin. Simultaneously, the need for enhanced pharmacovigilance and larger clinical trials are warranted for regulatory approval of these agents.
The aim of this study was to evaluate the efficacy and safety of Razumab (the biosimilar Ranibizumab by Intas Pharmaceuticals Ltd.) for the treatment of chorioretinal vascular diseases such as diabetic macular edema (DME), choroidal neovascular membrane (CNVM), and macular edema secondary to retinal vein occlusion (RVO).
We conducted a single-center, retrospective study, including patients with DME, CNVM, and RVO, who had received treatment with Razumab® between October 2018 and September 2019. Primary outcome measures were the changes in corrected distance visual acuity (CDVA) and central foveal thickness (CFT) from baseline to 1 month and 3 months. Secondary outcome measures included intraocular pressure (IOP) at day 1, any signs of ocular inflammation or systemic adverse events during the follow-up.
One hundred and fifty-three eyes of 141 patients were analyzed. The indications included DME in 70 (45.8%) eyes, CNVM in 70 (45.8%) eyes, and RVO in 13 (8.4%) eyes. Mean CDVA improved from baseline (0.62 ± 0.44) to month 1 (0.45 ± 0.42) and maintained till 3 months (0.42 ± 0.44; P < 0.001). Mean CFT showed significant reduction from baseline (405.68 ± 192.422 μm) to month 1 (286.08 ± 118.36 μm) and month 3 (271 ± 104.24 μm; P < 0.001). None of the eyes recorded IOP >20 mmHg on day 1. No evidence of ocular toxicity or systemic adverse event was noted.
Razumab® showed a rapid improvement in CDVA and CFT in most of the eyes with efficacy observed as early as 1 month and maintained till 3 months. The biosimilar Ranibizumab can be a safe and effective low-cost drug for treating macular diseases.
