In the same way that general practitioners perform yearly physicals to diagnose diseases in their infancy, ophthalmologists complete slit lamp exams to ensure continued eye health—because the sooner a problem is detected the more successful treatment is.
What is a Slit Lamp?
Essentially, a slit lamp is a device that consists of a microscope and light source so that an ophthalmologist can effectively view several parts of the eye in detail, including the iris, lens, sclera, conjunctiva, eyelids, and cornea. With additional lenses, the optic nerve and retina can also be seen. Oftentimes, a camera is part of the slit lamp so that photographs and video can be captured during the exam for future reference.
Slit Lamp Exams and Eye Health
As far as eye health is concerned, few things are more important than slit lamp exams. They allow an ophthalmologist to thoroughly inspect the inner workings of the eye to ensure everything is functioning as it should. With the help of dilation and fluorescein dye, a number of serious eye conditions can be detected so that the proper treatment can begin immediately. When performed routinely, slit lamp exams can help ophthalmologists diagnose eye health issues with enough time to either halt or reverse the condition. Some of the most common eye problems found through slit lamp exams include:
- Macular Degeneration
- Retinal Detachment
- Corneal Abrasion
- Dry Eye Syndrome
- Retinal Vessel Occlusion
- Retinitis Pigmentosa
- And more
Steps of a Slit Lamp Exam
While slit lamp exams vary based on the age and medical history of the patient, most of them follow these steps:
- The ophthalmologist will begin by placing dilating drops in the eye to make everything easier to see.
- The patient then sits down and rests their chin and forehead against the slit lamp so the head cannot be moved.
- The overhead lights will be dimmed and the slit lamp will be placed in position in front of the patient’s eyes.
- The bright light on the slit lamp will be directed into the patient’s eyes, as the doctor looks into the microscope—all the while the camera is at work taking photos or video.
- If necessary, fluorescein dye will then be applied to help the ophthalmologist easily view any scratches or other abnormalities.
- After the doctor has viewed both eyes in their entirety, the slit lamp exam is complete. From start to finish, the process usually takes 5-10 minutes.
Slit lamp exams are a crucial component of eye health. When they are performed regularly, many eye conditions can be treated successfully. At Coburn Technologies, we feature the finest slit lamps available to make sure that ophthalmologists are able to correctly diagnose and treat their patients.
