The efficacy of telemedicine for ophthalmology triage by a general practitioner

Although there are enough ophthalmologists for the Brazilian population, they are not evenly distributed throughout the country. Tele-ophthalmology may therefore be a useful tool. We have examined the feasibility of ophthalmology triage, performed by a general practitioner (GP) with remote support from an ophthalmologist. Forty patients with a variety of external and internal eye disorders were examined by the GP and also reassessed by an ophthalmologist, face to face, and then remotely by another ophthalmologist. There was agreement in 95% of the diagnoses between face-to-face and distant evaluation. The use of a digital camera and slit-lamp allowed greater accuracy of telediagnosis than the use of a digital camera alone. The GP would have referred 36 patients to an ophthalmologist, while both the local and the remote ophthalmologist saw the need for referral in 31 cases, i.e. assessment by tele-ophthalmology resulted in a 14% decrease in referrals. GP triage therefore appears to be feasible after appropriate training.
