Endothelial dysfunction after scleral lens use in patients with herpetic eye disease
Herpes simplex virus and varicella zoster virus (VZV) affect approximately 4 billion individuals globally. When the infection involves the ophthalmic division of the trigeminal nerve (V1), they are termed “herpetic keratitis” (HK) and “herpes zoster ophthalmicus” (HZO). The estimated incidence of VZV is 4/1000 people, with approximately 10–20% of cases demonstrating ocular involvement.1 HK has been approximated to affect 1.5 million people with an estimated incidence of 11.8/100,000. Together, these are thought to be the leading cause of infectious ocular blindness in the developed world.National survey of Canadian Retina Society members on guidelines for ophthalmic care during the COVID-19 crisis: Canadian Retina Research Network (CR2N) COVID-19 Steering Committee analysis
An anonymous survey was designed by the Canadian Retina Research Network coronavirus disease 2019 (COVID-19) Steering Committee to assess awareness of, confidence in, and adherence to recent guidelines released by the Canadian Ophthalmology Society (COS) and Canadian Retina Society (CRS) for ophthalmic care during the COVID-19 pandemic.1,2 The survey was pilot-tested and validated with 9 content experts. It was then distributed via email to physician members of the CRS in May 2020 with one reminder email to maximize response rate.
