Which tool is used to rule out retinal detachments or mass effects during cataract work-up?

Explanation:
When the eye has a dense cataract, you can’t see the back of the eye to check for retinal problems. Imaging through the opaque lens is essential to make sure there’s no retinal detachment or mass effect before proceeding with cataract surgery. Ocular ultrasound does exactly this: it uses high-frequency sound waves to create cross-sectional images of the retina, vitreous, and posterior structures, revealing detachments, masses, or other pathology even when the view is blocked. It’s quick, noninvasive, and can be done at the bedside. Fluorescein staining, by contrast, is used to evaluate the corneal surface and tear film, highlighting epithelial defects like abrasions or ulcers. It doesn’t provide information about the posterior segment. Gonioscopy examines the anterior chamber angle to assess glaucoma risk, not retinal or posterior issues. Visual field testing measures functional vision and overall field loss, not the structural status of the retina or presence of a mass. So the tool best suited to rule out retinal detachments or mass effects during cataract work-up is ocular ultrasound.
