If you are experiencing symptoms such as blurred or cloudy vision, haloes, difficulty with night driving, or the loss of crisp, clear vision, schedule an appointment immediately. Your eye specialist will inquire into your family history of eye diseases, your symptoms, and any risk factors. Various diagnostic tests may be performed:
- Visual acuity test: This test is the standard eye chart with various sizes of letters to evaluate your vision close and distance vision.
- Slit-lamp examination: A special lamp that emits a thin beam of light, allows your eye specialist to evaluate the structures within your eye, including the cornea, iris, lens, and other inner eye structures.
- Retinal examination: Your pupils are dilated with eye drops to allow your eye doctor a clear view of the inner structure of your eye, particularly the retina. A special diagnostic device called an ophthalmoscope is used to magnify the inner eye to identify cataracts, glaucoma, or other eye diseases or conditions.
- Eye pressure exam: Measures eye pressure to identify glaucoma, involving a puff of air onto the eye.
- Ocular motility: Evaluates eye movement and ability to track motion.
