This includes several tests in cataract surgery Hong Kong, such as the visual field test, which measures peripheral vision; its loss may be a sign of glaucoma. Tonometry measures the internal pressure of the eye, which also helps in detecting glaucoma. A visual acuity test tests how well a person can see at different distances. Refraction tests help identify the lenses that will affect the clearest vision. Dilation involves dilating the pupils with eye drops so that the eyes can be examined with special magnifying lenses; this provides a clear view of important tissues located in the back of the eye, such as the optic nerve, macula, and retina.

Cardiovascular disease causes small lumps of cholesterol to pass through the blood vessels. Neurological disorders such as multiple sclerosis start with inflammation of the optic nerve. Swelling of the optic nerve can also indicate a brain tumor. An ophthalmologist may be the first to detect certain types of cancer, such as melanoma of the eye.
