The most commonly used method to measure vision is visual acuity. However, this technique only measures the function of central point (fovea) of the central portion of the retina (macula). Patients with diseases that spare the fovea will not show impairment of visual acuity until late in the disease process. Therefore, a better method of monitoring the central region of the retina is required for many types of macular diseases.
Microperimetry combines a fundus tracking camera with visual field test. We have a large library of microperimetry data from healthy subjects and patients with various eye diseases (including inherited retinal disease, macular degeneration, ocular injury, drug toxicity, inflammatory eye disease, myopic degeneration and glaucoma). Undergraduate and postgraduate students and junior doctors can be involved in performing microperimetry examinations and data analysis of longitudinal changes in microperimetry measurements.
