This study will evaluate a system developed to grade the severity of age-related cataract, a common cause of vision loss in older adults. Cataract research requires methods to simply and accurately determine the type and severity of cataracts in order to develop new, possibly non-surgical, treatments. Patients 50 years of age and older with one of the three major age-related cataract types (nuclear, cortical, and posterior subcapsular) may be eligible for this study. Participants will be recruited from among patients enrolled in other National Eye Institute protocols. Participants will have their eyes examined independently by two ophthalmologists with a biomicroscope, a magnifying device routinely used during eye examinations. The doctors will use the new grading system to record if a cataract is present, and if so, how severe it is. The examination includes measurement of visual acuity (vision chart test) and examination of the lens, retina, pupils and eye movements. Photographs of the eye will be taken using a special camera that flashes a bright light in the eye.
