Which of the following tests assesses peripheral vision in RP testing?

Explanation:
In retinitis pigmentosa, peripheral vision is lost first as the peripheral rods degenerate, so the test that maps the outer visual field is essential. The Goldmann Visual Field is a kinetic perimetry method that uses moving light stimuli of different sizes and brightness to chart the entire field, including the far periphery. This lets you see the extent and pattern of peripheral field loss, such as constriction toward tunnel vision or ring-shaped scotomas, which are characteristic in RP. By comparison, a Snellen chart measures central visual acuity only, an Amsler grid focuses on the central macula for metamorphopsia, and Optical coherence tomography provides structural retinal imaging rather than functional field mapping.
