All India Ophthalmological Society members survey results: Cataract surgery antibiotic prophylaxis current practice pattern 2017.

Purpose: The purpose of this article is to document the current practice pattern of Indian ophthalmologists for antibiotic prophylaxis in cataract surgery to prevent endophthalmitis.

Methods: Fifteen structured questions were sent online to all ophthalmologists registered with the All India Ophthalmological Society. The questionnaire was divided into three main categories of prophylaxis - preoperative, intraoperative, and postoperative.

Changing profile of organisms causing scleral buckle infections: a clinico-microbiological case series.

Purpose: To study the microbiological spectrum and in vitro susceptibility of bacterial isolates from explanted scleral buckles and to correlate clinical presentation to the causative agent.

Method: Medical records of patients who underwent buckle explantation from July 2007 to May 2012 were reviewed retrospectively. Clinical features and microbiological profile were noted and correlated.

Hemoglobin magnetism in aqueous solution probed by muon spin relaxation and future applications to brain research.

A marked difference in spin relaxation behavior due to hemoglobin magnetism was found for positive muons (μ(+)) in deoxyhemoglobin in comparison with that observed in oxyhemoglobin in aqueous solution at room temperature under zero and external longitudinal magnetic fields upto 0.4 Tesla. At the same time, small but significant unique relaxation pattern was observed in nonmagnetic oxyhemoglobin.
