PURPOSE: To report the feasibility of real-time video and audio transmission of slit-lamp images of the eye using conventional telephone systems. METHOD: We analyzed the feasibility and benefits of telemedicine in the diagnosis and follow-up of ocular surface disorders in referral patients using a real-time audio-video system that functions through integrated services digital network lines at a transmission speed of 384 kilobytes per second. RESULTS: Real-time slit-lamp images obtained through integrated services digital network lines offered satisfactory visual resolution of the ocular surface for the diagnosis and follow-up of ocular surface and corneal disease, while simultaneous audio transmission allowed for direct communication with the patient and attending physician when necessary. CONCLUSION: Telemedicine using conventional telecommunication infrastructures offers sufficient information for the diagnosis and follow-up of ocular surface disorders in referral patients.
