A complete visual examination of the sight, especially if it is performed periodically, is the best way to prevent or detect at an early stage any disease that may compromise our vision.
In many cases, a comprehensive eye exam may be the only way to diagnose really serious illnesses early, some of which can cause irreversible loss of vision and, in the most extreme cases, even blindness.
What Is A Comprehensive Eye Exam?
A complete eye examination is a painless procedure in which an ophthalmologist carries out a comprehensive review of our eyesight to confirm that we are not suffering from any abnormality, or to make an accurate diagnosis of a pathology or vision problem.
During the examination, the specialist examines the different parts of the patient’s eyes, especially those most susceptible to suffering some pathology, especially the retina. A dilated eye exam also allows the doctor to observe if it has caused some damage to the optic nerve, which happens when a person has, for example, glaucoma.
What Tests Does A Comprehensive Eye Exam Include?
A comprehensive eye exam may be configured by the following tests: fundus examination, tonometry, and visual field examination. These tests are hardly inconvenient for the patient and the eye exam cost is cheap and affordable.
Of course, the effect of the dilation drops of the pupils will make your vision blur (especially at close distances) for a few hours. Let’s see what each of them consist of:
1. Examination Of The Fundus With Dilated Pupils
First, the ophthalmologist puts a few drops in the patient’s eyes to dilate or enlarge the pupils. Subsequently, the professional look through a special magnifying lens to examine your eye for signs of possible pathologies or damage to the retina.
This test is used to measure the pressure or tension of the eye. High pressure can be a sign of glaucoma; an eye disease characterized by loss of vision as a result of damage to the secondary optic nerve, usually caused by increased intraocular pressure (IOP).
3. Visual Field Test Or Campimetry
This test measures lateral or peripheral vision and consists of the patient focusing one or both eyes on a fixed point and indicating when he perceives a bright point or an object placed in front of him. After comparing with the indicative values of healthy people, the examining physician assesses whether the patient’s visual field is normal or restricted.
