During VR ocular health assessment, what information is gained to guide rehabilitation?

• A. Location of scotoma and extent of visual field loss
• B. Color discrimination
• C. Ocular surface health
• D. Intraocular pressure

Answer: (A)

Understanding where vision is lost in the field is what drives rehabilitation planning. Mapping the location of scotomas and how large the visual field loss is tells you exactly where the patient can rely on usable vision. With that information, you can tailor rehabilitation by teaching strategies that compensate for the missing areas—such as guiding gaze or head movements to bring targets into intact parts of the field, and practicing scanning patterns so important details aren’t missed. The extent of the loss also helps set realistic goals and determine how much training or what specific techniques are needed, and it informs the placement of tasks and stimuli in a virtual-reality environment to maximize usable vision.

Color discrimination, while part of a broad assessment, doesn’t directly dictate how to rehabilitate functional vision in a VR setting. Ocular surface health and intraocular pressure are important for overall eye health but do not by themselves shape the day-to-day rehabilitation strategies focused on compensating for field loss.
