Which structures can be visualized during an ophthalmic examination?

• A. Cornea and lens
• B. Arteries and veins
• C. Retina and sclera
• D. Iris and pupil

Answer: (B)

The correct structures that can typically be visualized during an ophthalmic examination include the cornea, lens, retina, sclera, iris, and pupil. Among these, the most critical structures for ophthalmologists to observe during a routine examination are the cornea and lens, which are part of the anterior segment of the eye. The outermost layer, the cornea, is crucial for clear vision, as it refracts light entering the eye. The lens, located just behind the cornea, allows for the accommodation process, enabling focus on objects at various distances. Visualizing these two structures is essential for diagnosing conditions such as cataracts or corneal diseases. While arteries and veins are present in the ocular microvasculature and can be observed indirectly during a dilated fundoscopic examination, they are not the primary focus of a routine examination. The retina and sclera are also important; the retina is crucial for visual processing, whereas the sclera provides structural support. The iris and pupil are significant for assessing light response and eye health. Understanding the anatomy and functionality of these structures helps in evaluating ocular health and diagnosing potential pathologies effectively.
