Routine eye exams can help your optometrist diagnose early-stage ocular diseases such as glaucoma before they progress to total vision loss. Your eye doctor will look inside your eye with a slit lamp and ophthalmoscope, and if warranted, order additional diagnostic testing if your exam undercovers any abnormalities. Here are some ways eye exams can reveal the presence of glaucoma.
Glaucoma causes an increase in eye pressure, which if not recognized and treated early in its progression, can lead to vision loss.
The term "eye doctor" is used pretty loosely, at least in the United States. There are actually two types of professionals who this title could be referring to. The first is optometrists. These medical professionals are not technically medical doctors, although they do hold an advanced, professional degree. They specialize in analyzing vision and prescribing glasses and contacts. Then, there are ophthalmologists; these are medical doctors who specialize in treating conditions of the eye.
