Retinal Cameras use Complex, Costly Optical Alignment Systems Retinal or fundus cameras are used to photograph the retina to screen for and monitor such eye diseases as diabetic retinopathy, hypertensive retinopathy, macular degeneration, glaucoma, choroidal nevus, retinal lesions and optic neuropathy. The current form of retinal cameras is such that a camera was merely added to complicated optical equipment originally designed to allow a physician to look into the eye of the patient. The camera replaced the examiner’s eye, but the complex optical alignment system that allowed direct viewing of the retina was never simplified, thus making retinal cameras unnecessarily costly and bulky. A more affordable retinal camera will allow more clinics to purchase the device and perform the appropriate screening.
Semi-Spherical Retinal Camera Simplifies Capturing Pupil Imaging without Dilation The technology is a new type of retinal camera that bypasses the complicated optics of traditional retinal cameras. The semi-spherical camera comprises detectors along its interior surface to capture the image and an illumination source to illuminate the eye. The camera can be easily focused by adjusting its position in relation to the patient’s eye. Furthermore, no pupil dilation is required to obtain a wide angle view of the retina.
Applications: • Diabetic retinopathy • Hypertensive retinopathy • Macular degeneration • Glaucoma • Retinal lesions • Optic neuropathy • Third world use • Telemedicine
Advantages: • Lower manufacturing cost • Smaller footprint • Faster acquisition times • Wide field of view of retina • No pupil dilation required • Expand market beyond the 20-30% of ophthalmologists and optometrists that already have a retinal camera to family physicians and internal medicine physicians who manage diabetes and high blood pressure
