PROCEDURE Pupillary dilation was achieved with rocuronium bromide (5 mg/mL) at 0, 2, 15, 17, 30, and 32 minutes. The animals were sedated with midazolam maleate (0.5 mg/kg/IM) and anesthetized with propofol (5.0 mg/kg/IV). Measurements were made to evaluate the thickness of the total retina (TR), sensorineural retinal (SR), and ganglion cell complex (GCC), 2 millimeters (mm) from the pecten toward the fovea. OCT data were compared to measurements of retinal histological slides from enucleated eyes of blue-fronted parrots, scanned in automatic fluorescence microscope and measured with by the VS-ASW® software. RESULTS Averages of measurements from the 43 retinas evaluated by OCT were TR 279.40 micrometers (euthanized animals or enucleated eyes. © 2020 American College of Veterinary Ophthalmologists.IMPORTANCE Ophthalmology faces imperatives to improve sustainability, but there is uncertainty about how to respond. BACKGROUND We sought New Zealand ophthalmologists' opinions on climate change, sustainability and the role of ophthalmologists in responding to these issues, as well as information on the extent that ophthalmology practices are acting on sustainability. DESIGN Anonymous online survey of New Zealand fellows and trainees (178) of the Royal Australian and New Zealand College of Ophthalmologists (RANZCO) was conducted. PARTICIPANTS Forty-seven respondents (response rate 26%) were included in the study. METHODS Respondents were asked their level of agreement with statements on climate, health and sustainability and invited to comment. Current sustainability activities were collected from clinical
