We review the use of telemedicine in glaucoma and its possible roles in the COVID-19 outbreak . We performed a literature search of published human studies on teleglaucoma on May 12 , 2020, using search terms including``telemedicine"and``glaucoma"that were in English and published over the prior 10 years . This search strategy yielded a total of 14 relevant articles after manual curation . Of the 14 articles , 4 were from the same randomized control trial , 7 were prospective studies , 2 were retrospective studies , 1 was descriptive analysis, and 1 was cost-effective analysis . Seven discussed the common ophthalmologic measurements used in teleglaucoma . Four demonstrated the cost effectiveness of the use of teleglaucoma, and 3 articles investigated patient satisfaction with the use of teleglaucoma . Three articles investigated the correlation between teleglaucoma and face-to-face clinics . Five articles discussed the current use and opportunities of teleglaucoma . When compared to in-person care, teleglaucoma is more time and cost-effective, shows high patient satisfaction and fair to good agreement with in-person care; however, there is great variation in the reported sensitivity of glaucoma screening, warranting further studies to establish its efficacy . For glaucoma management, both the sensitivity and specificity must be further improved before it could be put into extensive use . Nevertheless, it is worthwhile to explore the possible extensive application of teleglaucoma in monitoring``glaucoma suspects"and maintaining glaucoma follow-up during a pandemic outbreak to reduce the risk of transmission of infection.
