Diagnostic Tests

Visual Field Test

The visual field is the total area in which objects can be seen in the peripheral vision while the eye is focused on a central point. This test can provide a map of visual field loss. Examination of the visual field enables your physician to diagnose and evaluate conditions that can cause visual field defects. Macular degeneration, retinal detachment and optic nerve damage from glaucoma are only some of the conditions that can cause defects in the visual field.

In this diagnostic procedure, a vegetable-based dye is injected into a vein in the arm, forearm or hand. A high resolution camera will then take a rapid sequence of photographs which are subsequently analyzed by a computer. By looking at these photographs your physician can evaluate the circulation of blood to the retina and the choroid. Fluorescein angiography is often helpful in the diagnosis and assessment of conditions like macular degeneration, diabetic retinopathy, hypertensive retinopathy and other vascular and chorioretinal diseases.

Optical Coherence Tomography (OCT)

This procedure measures the thickness of the retina at the micron level. Using this technology your physician can obtain optical scans of a cross-section of the retina. This will help your physician identify many types of retinal abnormalities. OCT is useful in the evaluation of conditions like age-related macular edema, diabetic macular edema, cystoid macular edema and macular holes.

If direct visualization of structures inside the eye is difficult or impossible because of an obstruction like a cataract or a hemorrhage, ocular ultrasound can give your physician valuable information on the inside of the eye. Ultrasound uses sound waves reflected from eye tissue to produce an image of the eye's anatomy. An ocular ultrasound is used to diagnose a variety of conditions like vitreous hemorrhage and ocular tumors.
