Fundus lenses are commonly used with Slit Lamp for what purpose?

• A. Posterior segment evaluation
• B. Anterior chamber depth measurement
• C. Corneal topography
• D. Pupil size assessment

Answer: (A)

Fundus lenses used with a slit lamp are for posterior segment evaluation. They help you view the retina, optic nerve head, macula, and retinal vessels by creating a magnified image of the fundus through the pupil, allowing detailed assessment of the back of the eye for conditions like retinal tears, detachments, diabetic retinopathy, and optic neuropathies. This isn't used for estimating anterior chamber depth, corneal topography, or simply measuring pupil size, which are done with other instruments or methods.
