Low Vision
Low vision services do not cure the cause of lost sight and they cannot restore lost vision. These services can help a patient use the remaining vision more efficiently and to its fullest potential. These enhancements may take many forms including microscopic bifocals for reading, telescopes for distance and special tints to reduce glare. Some devices are designed to enhance awareness of surrounding objects for the person with limited side vision.
The Low Vision Examination
The services of the low vision specialist begin with a careful examination requiring one to three hours and may require more than one visit. It includes a thorough case history, measurements of functional vision, evaluation with microscopic, telescopic and closed circuit television systems and other tests required to determine the appropriate low vision aids. Next the doctor will develop a plan and explain it to the patient and family. If low vision aids are prescribed, the doctor and staff will fit the aids and train the patient in their use. Return visits are usually required to check on the progress of the patient and to make any needed changes in the aids or the training regimen.
