Diagnosis & Testing

Retina specialists diagnose retinal diseases using highly technical equipment and testing. Dr. Alhabshan may perform the following tests to diagnose your condition.

Optical Coherence Tomography (OCT)

Optical coherence tomography (OCT) is a noninvasive imaging method that uses light waves to take cross-section pictures of your retina. It can be used to diagnose diseases such as diabetes-related retinopathy and glaucoma. It is effectively an "optical ultrasound".

Fluorescein Angiography (FA)

Fluorescein angiography is an eye test that uses a special dye and camera to look at blood flow in the retina and choroid, the two layers in the back of the eye. If blockage or leakage is present, the pictures will map the location for possible treatment.
