Which of the following is a component of a vision rehabilitation exam?

• A. Field enhancement
• B. Ocular prosthesis fabrication
• C. Laser refractive surgery
• D. Colonoscopy

Answer: (A)

Evaluating how to maximize functional vision is the main focus of a vision rehabilitation exam. This type of exam looks at how vision loss affects daily activities and what can be done to improve independence, including assessing the patient’s visual field and planning field-enhancing strategies. Field enhancement refers to approaches that help a person use their remaining field more effectively, such as evaluating or prescribing prism devices, training in scanning, and developing eccentric viewing techniques to expand functional vision. This is why it’s considered a component of the rehabilitation evaluation.

Ocular prosthesis fabrication is a service that creates a cosmetic or functional prosthetic eye, not part of the diagnostic assessment. Laser refractive surgery is a medical procedure to change the eye’s refractive error, not an exam component. Colonoscopy is unrelated to eye care.
