Community-based screening programs have had limited success in preventing vision loss from glaucoma due to overall low prevalence of glaucoma, screening limitations, and barriers to follow-up appointments. This editorial highlights lessons learned from two large prospective trials: the Philadelphia Telemedicine Glaucoma Detection and Follow-up Study (PTGDFS) and the Screening To Prevent Glaucoma Study (SToPGS). While some lessons are specific to ophthalmology, many lessons are applicable to screening for asymptomatic diseases in underserved, vulnerable communities.

从两项基于社区的大型青光眼筛查研究中吸取的教训。

由于青光眼的总体患病率较低、筛查的局限性以及随访预约的障碍，基于社区的筛查计划在预防青光眼导致的视力丧失方面取得的成功有限。这篇社论重点介绍了从两项大型前瞻性试验中吸取的经验教训：费城远程医疗青光眼检测和随访研究 (PTGDFS) 和筛查预防青光眼研究 (SToPGS)。虽然有些课程是专门针对眼科的，但​​许多课程适用于在服务不足的脆弱社区筛查无症状疾病。
