Diagnosis of Eye Injuries

As with any medical condition, the history is very important. How the injury occurred will often help the ophthalmologist focus the examination. A patient's vision (visual acuity) will be checked, so patients should bring their glasses to the office visit. The ophthalmologist is interested in preserving the best vision that a individual's eye(s) can achieve.

• To check for injuries to the cornea, the ophthalmologist or emergency medicine doctor usually uses a drop of special dye or stain into the tear-lubricated area that normally lubricates the eye. The dye is called fluorescein, which stains those areas of the cornea that have been damaged. When a blue light is shone over the eye, corneal abrasions turn green.
• A device called a slit lamp is often used as well. A slit lamp is essentially a special magnifying and illuminating microscope to look more closely at the eye.
• X-rays are rarely used, except if an orbital fracture, intraocular, or intraorbital foreign body is suspected. Corneal foreign bodies do not require X-rays.
