Diagnostic Tests


Ocular ultrasonography is a diagnostic method by which the  lens, vitreus, retina and soft tissues around the eye are visualised. Using the reflection of sound waves off tissue, this is a non-invasive, painless, easy-to-apply test which provides information about the posterior segment of the eye, particularly the retina. Evaluation requires experience.

When the internal structures of the eye cannot be evaluated because of blurred surroundings such as internal bleeding in cataract, it is a useful method in the diagnosis and monitoring of in retinal detachment, foreign body in the eye or tumours.
