Which testing method is used to evaluate lattice degeneration?

• A. Optical coherence tomography
• B. Direct ophthalmoscopy with scleral depression
• C. DFE with scleral depression
• D. Visual field testing only

Answer: (C)

Lattice degeneration sits in the far periphery of the retina, so detecting it requires examining the peripheral retina with the pupil dilated and the far retina brought into view. A dilated fundus exam with scleral depression provides the widest, most reliable view of the mid- to far-peripheral retina, making it the standard method to identify lattice degeneration. Optical coherence tomography focuses on cross-sectional imaging of the central retina and does not reliably visualize peripheral lesions. Visual field testing assesses functional sensitivity rather than revealing anatomic peripheral findings. While direct ophthalmoscopy with scleral depression can inspect the periphery to some extent, it offers a more limited field and is less thorough than a full dilated fundus exam with scleral depression.
