There are many different types of ophthalmic equipment, including opthalmoscopes, slit lamps, and retinoscopes. These instruments enable the doctor to exam the eye and determine what, if anything, is wrong and if there might be problems in the future. Opthalmoscopes are often used on a dilated eye to determine its overall health. Slit lamps are also used for a similar task, but their appearance is much different, though they looks nothing like their name implies. Lastly, retinoscopes shine light on the eye, which the doctor observes to see if the patient has difficulty processing light.
The ophthalmoscope is a type of small, hand-held ophthalmic equipment. It has a light and lens that is used by a general practitioner or eye doctor to examine various aspects of an eye. This instrument is the size of a small flash flight, and most people who have had a checkup with a doctor have seen one. It is used to detect problems such as brain tumors, glaucoma, and swollen optic discs. The eye being examined is often dilated so that it can be examined more effectively.
A slit lamp is a piece of ophthalmic equipment used to examine the eyes and look for potential problems, and it is one of the largest routinely used pieces of ophthalmic equipment. It is referred to as a lamp because part of its primary function is to concentrate a bright light at an eye, not because of any resemblance to a household lamp. While it is shining the light, the optometrist is able to use the magnifying lens of the slit lamp to examine the eye of the patient. The light helps reveal issues that would not be readily visible with a magnifying device. This device can emit different sized and angled beams of light and utilize its magnifying lenses in various ways to implement different examination techniques.
A retinoscope is a piece of ophthalmic equipment that is used to figure out if an eye has problems focusing light. The doctor using this piece of equipment shines light off the patient’s eye and observes how it is reflected. This technique can be used to determine how to fix the vision of a person who is unable or unwilling to respond during more typical vision testing. For example, an eye doctor might use this piece of equipment on a baby, toddler, or severely disabled person who needs corrective lenses.
