The Ophthalmic Ultrasound Service at the Wilmer Eye Institute provides specialized diagnostic testing for diagnosing complex cases such as vitreous hemorrhage, retinal detachment, ocular tumors, optic disc edema and thyroid eye disease.

The Ophthalmic Photography Service at the Wilmer Eye Institute provides clinical and research related diagnostic images that are used by ophthalmic personnel in managing patients with various ocular conditions. The service offers multiple camera and imaging systems used to capture data. Ophthalmic photographers perform testing in clinics and operating rooms, work independently at Wilmer satellite locations, and participate in related investigative studies requiring protocol specific imaging.

The Visual Physiology Service at the Wilmer Eye Institute performs special tests to diagnose night blindness, color vision disorders, hereditary retinal disorders and other diseases. Often, these diseases cannot be diagnosed during routine examinations or require additional studies for the ophthalmologist to determine the correct diagnosis.
