For this purpose, many doctors use a “slit lamp”. It is a special microscope and light that allow the doctor to see the eyes in 3D, both inside and out. They will use it together with an ophthalmoscope to look at the back of the eye. The slit lamp exam is usually done during a regular checkup with the eye doctor.
A slit lamp is a microscope with a bright light that is used during an eye exam. It allows the ophthalmologist to take a closer look at the different structures in the front and inside of the eye. It is a key tool for determining eye health and detecting eye diseases. The person will sit in a chair in front of the slit lamp with the chin and forehead resting on a support.
The person will sit with their head resting on the microscope with a slit lamp and the doctor will place a special contact lens directly on the eyeball. A slit lamp exam is generally very safe, although medications that dilate the pupils carry some risks. It will then turn on the slit lamp and focus a narrow, high-intensity beam of light toward the eye.
