Philadelphia Telemedicine Glaucoma Detection and Follow-up Study: Methods and Screening Results.

Area of Science:

• Ophthalmology
• Public Health
• Telemedicine

Background:

• Glaucoma is a leading cause of irreversible blindness.
• Early detection and intervention are crucial for managing glaucoma.
• Telemedicine offers a potential solution to increase access to eye care, particularly in underserved populations.

Purpose of the Study:

• To describe the methodology and screening results of the Philadelphia Telemedicine Glaucoma Detection and Follow-up Study.
• To evaluate the effectiveness of telemedicine for glaucoma screening in primary care settings.

Main Methods:

• Prospective randomized clinical trial screening program.
• Recruitment of diverse populations (African-American, Hispanic/Latino, Asian, White) based on age and risk factors (family history of glaucoma or diabetes).
• Telemedicine screening (Visit 1) conducted in primary care offices and Federally Qualified Health Centers, involving fundus photography, anterior segment imaging, medical/ocular history, visual acuity, and intraocular pressure measurement.
• Remote image interpretation by a trained retina reader and a glaucoma specialist.

Main Results:

• 906 participants consented, with a mean age of 58.7 years; 61.0% female, 60.7% African-American.
• High prevalence of comorbidities: 58.7% had diabetes, 68% had hypertension.
• Abnormal screening results were common: 36.8% had abnormal images, 28.5% showed suspicious optic nerves, 6.8% had ocular hypertension, and 11.3% had diabetic retinopathy.

Conclusions:

• Integrated telemedicine screening in primary care settings is effective in detecting a high rate of suspicious optic nerves, ocular hypertension, and retinal pathology.
• This intervention shows promise for improving glaucoma detection and follow-up, especially in diverse and at-risk populations.
• Telemedicine facilitates early identification of eye diseases within community-based healthcare settings.
