Purpose: To review the current literature on Coronavirus Disease 2019 (COVID-19) virology and transmission; to present a decision tree for risk stratifying oculofacial plastic and orbital surgeries; and to generate personal protective equipment (PPE) recommendations by risk category. Methods: A comprehensive literature review on COVID-19 was conducted. A two-stage modified Delphi technique involving 18 oculofacial plastic and orbital surgeons across Canada was used to determine consensus risk-stratification criteria and PPE recommendations for surgeries performed in the North American context. ⋯ We present an algorithm for risk-stratification based on the nature of surgery and the anatomical sites involved and offer recommendations for PPE. Conclusions: Although universal droplet precautions are now recommended in most healthcare settings, some clinical situations require more stringent infection control measures. By highlighting high-risk scenarios specific to oculofacial plastic and orbital surgery, as well as PPE recommendations, we hope to enhance the safety of continued care during the COVID-19 pandemic.

In March 2020, at the outset of the current pandemic, ESOPRS issued detailed advice on the appropriate procedures that practicing oculoplastic surgeons should consider to limit the transmission of COVID-19, with this information updated in April 2020. This paper highlights the threat to training opportunities for future generations of oculoplastic surgeons, adjustments in healthcare delivery, modifications of scientific activity, and the possible role of telemedicine in oculoplastics.

At present, all parts of the world are hit hard by COVID-19. The first confirmed case of COVID-19 in the territory of Hong Kong was announced on January 23, 2020. ⋯ Three main aspects are discussed, namely clinical, administrative, and training and educational. We hope our experiences would provide reference to fellow oculoplastic colleagues in other parts of the world in fighting this COVID-19 pandemic.

Purpose: To evaluate thiol-disulfide homeostasis (TDH) and its relationship with clinical findings in patients with Graves' ophthalmopathy (GO). Methods: This study included 52 patients with GO and 34 healthy controls. Tests of TDH were conducted using the novel automated spectrophotometric method. ⋯ The mean disulfide levels and disulfide/native thiol % ratios of active GO patients were significantly higher than that of patients with inactive GO (p = 0.034, p = 0.001; respectively). There was a negative correlation between native thiol and CAS (r = -0.532, p = 0.001) and a positive correlation between disulfide/native thiol % ratio and CAS (r = 0.601, p < 0.001). Conclusions: The impairment of TDH indicates the presence of oxidative stress in moderate-to-severe GO, particularly in active GO and smokers.
