What instrument is used to look into the eye?

Ophthalmoscope. The Ophthalmoscope is a handheld device used to examine the interior of the eye. Often, this examination comes along with pupil dilation. Dilating a patient’s pupils allows for the eye doctor to get a better view of the structures behind it.

What is an eye Tester called?

Ophthalmoscope The ophthalmoscope helps the doctor to see and identify the indicators of possible eye diseases.

What is the machine called that eye doctors use?

When you imagine an eye appointment, do you picture yourself looking into a thick instrument with numerous lenses and dials? That machine is called a phoropter, and your optometrist uses it to conduct a retinoscopy. A retinoscopy allows the optometrist to approximate your optimal lens prescription.

What is Autorefractor?

An autorefractor is used to determine an individual’s prescription by measuring how light is affected as it reflects through the eyeball. The process is quick and painless for the patient, and the data ensures a baseline to determine the correct eyeglass or contact lens prescription.

What is ophthalmoscope used for?

It is used to detect and evaluate symptoms of retinal detachment or eye diseases such as glaucoma. Ophthalmoscopy may also be done if you have signs or symptoms of high blood pressure, diabetes, or other diseases that affect the blood vessels.

What is fundus of the eye?

The fundus is the inside, back surface of the eye. It is made up of the retina, macula, optic disc, fovea and blood vessels. With fundus photography, a special fundus camera points through the pupil to the back of the eye and takes pictures. These pictures help your eye doctor to find, watch and treat disease.

What is gonio in ophthalmology?

Gonioscopy is an eye examination to look at the front part of your eye (anterior chamber) between the cornea and the iris. Gonioscopy is a painless examination to see whether the area where fluid drains out of your eye (called the drainage angle) is open or closed.

Tonometers. used to determine the intraoccular pressure (IOP) – useful in glaucoma; video link for various types of tonometers.
