General instructions for Ophthalmoscopy (fundus exam)

Painless visual test that uses a special light with lenses to detail the back of the eye.

  • Definition: A painless visual test that uses a special light with lenses to examine the back of the eye in detail.
  • Fasting: No fasting necessary. You can eat your usual food and drink water or liquids normally before coming to your appointment.
  • Medication: You should maintain and take your usual medication at the appropriate times. If you use eye drops daily, apply them as usual, but remember that any doubt or adjustment about your treatments should always be discussed beforehand with your doctor.
  • Clothing and Accessories: We recommend wearing the clothes you feel most comfortable in. There is absolutely no restriction on metals, jewelry, piercings, or watches for this exam.
  • Specific Requirements: If you use contact lenses, the specialist will ask you to remove them before starting, so we suggest taking your case and liquid, or coming directly with your glasses. During the test, drops will be applied to dilate your pupils, so it is an essential requirement to come accompanied by an adult and bring sunglasses, as it will not be safe for you to drive home.
  • Expected discomfort or pain from the test: It is a completely safe procedure, without direct contact and causes no pain. Dilating drops may cause a slight sting that lasts only a few seconds. During the exam, the light from the equipment will be very bright and may dazzle you a bit. After the test, you will experience great sensitivity to light and have blurred vision (especially for near focus) for about 4 to 6 hours until the effect of the dilation passes.
