Which retinal pathology can be especially evaluated using ultrasound in cases of poor visual acuity?

Ultrasound is particularly effective in evaluating retinal detachment, especially in situations where poor visual acuity complicates the examination of the retina through traditional methods, such as direct ophthalmoscopy. In cases of retinal detachment, ultrasonography allows for a detailed assessment of the posterior segment of the eye, making it easier to visualize the extent of the detachment and any associated complications, such as vitreous hemorrhage or the presence of a retinal tear.

The ability of ultrasound to provide images in real-time and its capability to penetrate opaque media, like a dense cataract or vitreous hemorrhage that obscures the view of the fundus, makes it an invaluable tool in these cases. Additionally, ultrasound can help in determining the location of the detachment and informing potential therapeutic choices, which is crucial when patient visual acuity is compromised.

In contrast, other conditions like diabetic retinopathy, macular degeneration, and glaucoma may not require ultrasound as the first-line imaging modality, as they can often be evaluated with other imaging techniques or direct examination if the view is clear. While ultrasound can provide information about some of these conditions, it is not typically the primary method of evaluation when visual acuity is poor compared to the critical role it plays in
