Objectives: Anti-vascular endothelial growth factor (anti-VEGF) drugs delivered intravitreally have been proven effective and safe for the treatment of patients diagnosed with neovascular age-related macular degeneration (ARMD). This study evaluated the short-term biologic efficacy and safety of multiple intravitreal injections of bevacizumab in patients with neovascular ARMD. Methods: A prospective, interventional, placebo-controlled, randomized clinical trial was done involving patients with active subfoveal neovascular ARMD. Excluded were patients with significant media opacity, concomitant retinal/ocular diseases, previous intravitreal injections, recent laser treatment or intraocular surgery, and contraindications to the drug. Demographic data were taken and a complete ocular examination, fluorescein angiogram (FA), and optical coherence tomogram (OCT) were performed. Patients received either 3 monthly intravitreal injections of 1.25mg bevacizumab or sham injections. Best-corrected visual acuity (BCVA) and central macular thickness were recorded at baseline, 2, 4, 8, and 12 weeks follow-up. Ocular/Periocular or systemic drug-related side effects or toxicities and iatrogenic complications were noted. Results: Thirty eyes (15 per group) were included in the final analysis. Both treatment and control groups were comparable in baseline characteristics. There was a significant increase in the mean visual acuity (p < 0.001) in eyes treated with bevacizumab across all time periods. The average gain at the end of the study was 11.6 letters. This paralleled a similar significant decrease in central macular thickness for the treatment group (p < 0.02). No major ocular adverse events were noted. Conclusion This study supported the growing body of evidence that intravitreal injections of bevacizumab 1.25 mg result in short-term anatomical as well as functional improvement with minimal adverse events in patients with neovascular ARMD.

Objective: To determine the applicability of a modified criteria for initiating retinal examinations to screen for retinopathy of prematurity (ROP). Methods: All ROP charts of babies who had initial retinal examination to screen for ROP from January 1, 2005 to December 31, 2008 at the neonatal-intensivecare nursery and eye center of a tertiary hospital were reviewed. Date of birth, sex, age of gestation (AOG), birth weight (BW), postnatal age (PNA), postconceptional age (PCA), and ROP classification were recorded. Descriptive statistics and Student’s t-test were used to analyze the data. Results: A total of 690 eyes of 345 babies, 174 males and 171 females, were included in the study. At the initial retinal exam, the mean AOG was 31.39 ± 2.46 weeks; BW, 1,268.77± 317.12 grams; PNA, 4.56 ± 2.95 weeks; and PCA, 35.94 ± 3.26 weeks. Immature retinas in both eyes were seen in 175 (50.72%) babies, while 113 (32.75%) had ROP of any stage in both eyes and 51 (14.78%) had immature retina in one eye and ROP of any stage in the other eye. Among the 113 babies with ROP, 33 (29.2%) were assessed to have pre-threshold ROP. Conclusion This study supported the applicability of the modified criteria which are in agreement with the Joint Statements of the American Academy of Pediatrics, American Academy of Ophthalmology and American Association of Pediatric Ophthalmology and Strabismus, and the United Kingdom Royal College of Pediatrics and Child Health for initiating retinal exams to screen for ROP.
