Purpose To investigate differences in ocular blood flow in individuals of African descent (AD) and European descent (ED) with open angle glaucoma (OAG). Patients and Methods A retrospective data analysis was performed on OAG patients of AD and ED who were previously examined for ocular blood flow within the Department of Ophthalmology at Indiana University School of Medicine. Data analysis included blood pressure, heart rate, visual fields, intraocular pressure, ocular perfusion pressure, and color Doppler imaging of retrobulbar vessels. Color Doppler imaging measurements were performed on ophthalmic, central retinal, and nasal and temporal short posterior ciliary arteries, with peak systolic (PSV) and end diastolic velocities (EDV) as well as the Pourcelot vascular resistive index calculated for each vessel. Two-sample t tests of unequal variance were performed with P values <0.05 considered statistically significant. Results OAG patients of AD had statistically significant lower retrobulbar blood flow values than patients of ED including lower ophthalmic artery PSV (P=0.0001), ophthalmic artery EDV (P=0.0008), central retinal artery PSV (P=0.01), temporal short posterior ciliary artery PSV (P=0.0037), and nasal short posterior ciliary artery PSV (P<0.0001). No significant differences were found in terms of intraocular pressure or visual field parameters. Conclusions Significantly lower blood flow values were identified in all retrobulbar blood vessels in AD compared with ED OAG patients. These findings suggest that the contribution of ocular blood flow to the disease process may be different in AD compared with ED OAG patients.

The purpose of this review is to discuss the process of genericisation of medications in the US and Europe with a focus on ophthalmic drugs. Regulatory guidelines of the US Food and Drug Administration and the European Medicines Agency will be discussed, and the advantages and concerns of genericisation will be explored. We will look at various studies concerning the safety and efficacy of generic drugs compared to their branded counterparts. In particular, the challenges of assuring bioequivalence and therapeutic equivalence in topical ophthalmic drugs will be examined.

Prior bariatric surgery in patients hospitalized with AP is not adversely associated with in-hospital mortality, development of organ failure, or healthcare resource use. Bariatric surgery may mitigate the obesity-associated adverse prognostication in AP. These observations are pertinent for future research, because the prevalence of obesity and AP-related hospitalizations is increasing.

Purpose The purpose of this study was to examine the role of initial diabetes education delivery at an academic medical center (AMC) versus non-AMCs on long-term glycemic control. Methods We performed a retrospective study of children with type 1 diabetes referred to an AMC after being educated at non-AMCs. These children were matched to a group of children diagnosed and educated as inpatients at an AMC. The A1C levels at 2, 3, and 5 years from diagnosis were compared between the 2 groups of children. Results Records were identified from 138 children. Glycemic control was comparable in the non-AMC-educated versus AMC-educated patients at 2, 3, and 5 years from diagnosis. The A1C was also highly consistent in each patient over time. Conclusions Long-term glycemic control was independent of whether initial education was delivered at an AMC or non-AMC. Formal education and location at time of diagnosis do not appear to play a significant role in long-term glycemic control. Novel educational constructs, focusing on developmental stages of childhood and reeducation over time, are likely more important than education at time of diagnosis.
