AIM: To determine whether retinal circulatory changes play a role in the pathogenesis of macular disorders in patients who are otherwise healthy. METHODS: Patients with macular disorders that required angiographic imaging were included in this prospective case series. After a complete ocular exam,fluorescein angiography was performed using a standardized technique on the HRA-II(Heidelberg Engineering, Heidelberg, Germany) with special focus on the posterior pole. Only patients with good quality images were included in the analysis. Circulatory parameters recorded included the arm-choroid time,choroid-retinal artery, and finally the retinal artery-vein time. Zonal asymmetry(between the upper and lower zones divided by a line passing through the centre of the fovea) in transit times, if any was also noted. Appropriate statistical analysis was done. Circulation times were compared with age matched historical controls. Changes in retinal dye transit times relative to historical age matched controls, if any, were noted and compared between various ***: A total of 156 eyes of 156 patients(120 males)were included in the study. Mean age: 49.14 ±14.93 *** disorders studied were age related degeneration,polypoidal vasculopathy, central serous chorioretinopathy(CSCR) and parafoveal telangiectasia. Delayed circulation time was noted in CSCR patients ***: CSCR patients appear to have delayed arterial filling, retinal circulatory disturbances do not seem to contribute to the pathogenesis of other macular disorders.

Purpose: To determine the clinical profile, causes, and outcomes of traumatic vitreous hemorrhage(TVH) in children(<18 years of age).Methods:.Retrospective computer assisted chart review..501 eyes of 464 children(103 females; 361 males) who presented with TVH between 2001 and 2012 were included. All children underwent a complete ocular and systemic examination and investigation. The etiology, visual, and anatomic results of pediatric TVH were the outcome ***: Median age: 12.27±4.51 years. 37 patients had bilateral VH; 43.24% of these were firecracker injuries..Commonest complaint was diminished vision(96.45%)..Mean BCVA(logMAR) at presentation was 2.64±1.11 logMAR. Sticks(43.43%).and cricket balls.(13.24%).were the commonest causes..Treatment included medical therapy(topical and / or systemic; 56 eyes), laser photocoagulation(34 eyes), and /or surgery.(387 eyes)..Mean final BCVA was significantly better(1.01±0.58 logMAR;P=0.011,Z test). Mean follow up in the closed and open globe trauma was 47±12.47 and 36.24±9.72 months, ***:.TVH has significant implications in *** injuries are notorious for bilateral VH.
