Certified Ophthalmic Assistant Practice Exam

A slit lamp is a microscope that eye care professionals use to examine the eye closely. One of the main structures that a slit lamp is used to evaluate is the anterior chamber of the eye. The slit lamp allows the ophthalmologist or ophthalmic assistant to view the structures at the front of the eye, including the cornea, iris, and the anterior part of the lens. This examination is crucial in diagnosing conditions such as corneal injuries, uveitis, and glaucoma. Therefore, the correct answer is C - Anterior chamber.

The other options (A. Retina, B. Vitreous humor, D. Optic nerve) are not examined using a slit lamp because they are located deeper within the eye and require different instruments or techniques for evaluation. The retina is located at the back of the eye and is typically viewed using techniques such as funduscopy. The vitreous humor is a gel-like substance inside the eye, while the optic nerve is located at the back of the eye and is examined using methods like ophthalmoscopy.
