Purpose:
To investigate the use of a nonmydriatic digital color fundus camera and telemedicine as screening tools for age-related macular degeneration (AMD).
Methods:
Nonmydriatic color fundus photography was performed on patients consulting health examination centers and transmitted by telemedicine to an ophthalmology department. Rates for different grades of AMD were calculated and also statistically related to the presence or absence of risk factors.
Results:
Among the 1,022 patients screened, a total of 1,363 color fundus photographs were interpreted, with 80% gradable images, allowing a diagnosis of AMD in 178 photographs. Among all the gradable images, 83.7% had no AMD (grade 0). The rates of AMD at grades 1, 2, 3 and 4 were 8%, 5.6%, 2.3% and 0.4%, respectively. A statistical odds ratio was found between the presence of AMD on fundus photographs and age, familial history of AMD or prior cataract surgery.
Conclusions:
Nonmydriatic color fundus photography and telemedicine succeeded in screening for AMD.
