Purpose: To evaluate the efficacy and safety of intravitreal ranibizumab in diabetic macular edema (DME) patients. Design: Two parallel, methodologically identical, phase III, multicenter, double-masked, sham injectioncontrolled, randomized studies. Participants: Adults with vision loss from DME (best-corrected visual acuity [BCVA], 20/4020/320 Snellen equivalent) and central subfield thickness ≥275 μm on time-domain optical coherence tomography (OCT). Intervention: Monthly intravitreal ranibizumab (0.5 or 0.3 mg) or sham injections. Macular laser was available per-protocolspecified criteria.

Same-sex sexual behavior has been extensively documented in non-human animals. Here we review the contexts in which it has been studied, focusing on case studies that have tested both adaptive and non-adaptive explanations for the persistence of same-sex sexual behavior. Researchers have begun to make headway unraveling possible evolutionary origins of these behaviors and reasons for their maintenance in populations, and we advocate expanding these approaches to examine their role as agents of evolutionary change.
