It is critical that all patients be examined by an optometrist specializing in low vision care prior to other rehabilitation training to rule out potential medical or surgical correction for the problem and to establish a careful baseline refraction and prescription of both normal and low vision glasses and optical aids. Only a doctor is qualified to evaluate visual functioning of a compromised visual system effectively.
We determine the amount of remaining vision the patient has by performing a low vision evaluation. A low vision evaluation is not the same as a general eye exam.
Special charts and techniques are utilized to “draw out” any residual vision that may be “hiding” in the periphery. The patient’s regular eyeglass prescription is reviewed to note possible improvements. We see how magnification affects the level of vision. We also determine the amount of vision needed to do desired tasks with specific questions and demonstrations. We request that the patient bring samples of printed materials they want to see, and samples of activities they perform.
We recommend various magnification devices that the patient can work with in our office, and choose the device most suitable to their needs and requirements.
