General instructions for Optical coherence tomography (OCT)
Quick and non-invasive imaging test that uses light to photograph the eye's background in detail.
- Definition: A quick and non-invasive imaging test that uses light to take detailed photographs of the back of the eye.
- Fasting: No fasting necessary. You can eat your usual food and drink water or liquids normally before your appointment.
- Medication: You should maintain and take your usual medication, including any eye drops you use daily. As always, if you have any specific doubt about your treatments, consult your doctor beforehand.
- Clothing and Accessories: You can wear the clothes you feel most comfortable in. There are no restrictions on metals, jewelry, piercings, or watches for this test.
- Specific Requirements: If you use contact lenses, you may be asked to remove them during the exam, so we suggest taking your case or coming with your glasses. In many cases, the specialist will need to apply drops to dilate the pupils; if so, it's highly recommended to be accompanied by an adult, as you won't be able to drive home safely, and bring sunglasses to protect yourself from light afterward.
- Expected discomfort or pain from the test: It is a completely safe, quick procedure and causes no pain; the equipment will not touch your eye at any time. During the test, you will only notice a bright flash of light that can dazzle you for a few seconds. If you are given dilating drops, you will feel a slight initial sting and, subsequently, will have blurred near vision and sensitivity to light for a few hours.
