Eye doctors do a lot more than ask patients to read off an eye chart. They’re also looking for eye disorders and evidence of any other health issues that can affect sight. To do this, ophthalmologists use a variety of tools and devices to diagnose and treat eye conditions. Fundus cameras are one example of eye exam equipment you might find in an eye doctor’s office, and they’re essential for getting photographs of the inner eye. But what is a fundus camera, and how are they used? Capital Ophthalmic Instrument Services has everything you need to know about these handy devices!
What is a fundus camera?
A fundus camera is a specialized, low powered microscope attached to a flash-enabled camera. This device allows the operator to photograph the back of the eye, known as the fundus, through the patient’s pupil. Fundus photographs are routinely ordered for a broad variety of ophthalmic conditions. Generally, this is because retinal details are easier to see in stereoscopic photographs as opposed to direct examination. An ophthalmologist is then able to examine the photographs to better diagnose, monitor, and treat diseases of the eye.
How does a fundus camera work?
Before the eye exam procedure, the patient’s eyes are dilated with drops to increase the pupil size and expand the angle of observation. Dilation helps the technician photograph a wider area and obtain a clearer view of the rear eye. The patient sits in front of the fundus camera with their chin on the chin rest and their forehead against the bar. The technician then focuses and aligns the fundus camera before pressing the shutter release. A flash fires to illuminate the inside of the eye and capture a fundus photograph. Photographs can often be stored digitally and compared over time.
What is a fundus camera used for?
A fundus camera is used by ophthalmologists to inspect the back of the eye for anything unusual that might signal a developing eye disease, and to track any progression. Fundus photography can be used to identify glaucoma, multiple sclerosis, or diabetic retinopathy, as well as disease processes like macular degeneration, retinal neoplasms, and choroid disturbances. Photographs taken over time can be studied for subtle changes, allowing for more precise treatment options.
Fundus cameras are one of many essential optometry devices used by eye doctors to diagnose and treat eye diseases. Like most ophthalmic equipment, it’s important they remain calibrated and in good working order.
