Definition Ophthalmosco py is a test that allows your ophthalmologi st, or eye doctor, to look at the back of your eye. 3
Introduction This part of your eye is called the fundus, and consists of: Retina, Optic disc, Blood vessels This test is often included in a routine eye exam to screen for eye diseases. Your eye doctor may also order it if you have a condition that affects your blood vessels, such as high blood pressure or diabetes. Ophthalmoscopy may also be called funduscopy or retinal examination. 4
When is Ophthalmoscopy Used? Your eye doctor can use ophthalmoscopy to screen for eye diseases and conditions that can affect blood vessels. These conditions include: Damage to your optic nerve Retinal tear or detachment Glaucoma, which is excessive pressure in your eye Macular degeneration, a loss of vision in the center of your visual field 6
When is Ophthalmoscopy Used? Cytomegalovirus (CMV) retinitis, an infection of your retina Melanoma, a type of skin cancer that can spread to your eye Hypertension, which is also known as high blood pressure Diabetes 7
Preparation of Ophthalmoscopy Before conducting an ophthalmoscopy, your eye doctor may use eye drops to dilate your pupils. This makes them larger and easier to look through. These eye drops can make your vision blurry and sensitive to light for a few hours. You should bring sunglasses to your appointment to protect your eyes from bright light while your pupils are dilated. 8
Preparation of Ophthalmoscopy If you do work that requires clear vision, such as operating heavy machinery, you should also arrange to take the rest of the day off. If you re allergic to any medications, tell your eye doctor. They will likely avoid using eye drops if you re at risk of an allergic reaction. Some medications may also interact with the eye drops. 9
Preparation of Ophthalmoscopy It s important to tell your eye doctor about any medications that you take, including over-the- counter medications, prescription medications, and dietary supplements. Finally, you should tell your eye doctor if you have glaucoma or a family history of glaucoma. They probably won t use eye drops if they know or suspect that you have glaucoma. 10
During the Ophthalmoscopy At the beginning of the procedure, your eye doctor may use eye drops to dilate your pupils. The drops may cause your eyes to sting for a few seconds. They can also cause an unusual taste in your mouth. Your doctor will examine the back of your eye after your pupils are dilated. 11
During the Ophthalmoscopy There are three different types of examinations that could be done: Direct examination Indirect examination Slit-lamp examination Your doctor may perform one or more of these examinations to get a good view of your eye. 12
During the Ophthalmoscopy Direct examination You ll be seated in a chair. The lights in the room will be turned off. Your eye doctor will sit across from you and use an ophthalmoscope to examine your eye. An ophthalmoscope is an instrument that has a light and several small lenses on it. Your eye doctor can look through the lenses to examine your eye. 13
During the Ophthalmoscopy Indirect examination This test allows your eye doctor to see the structures in the back of your eye in more detail. For this test, you ll be asked to lie down or sit in a reclined position. Your eye doctor will wear a bright light positioned on their forehead. They will shine it in your eye while holding a lens in front of your eye to help them examine it. 14
During the Ophthalmoscopy Slit-lamp examination This procedure gives your eye doctor the same view of your eye as an indirect examination, but with greater magnification. You ll sit with an instrument in front of you, known as a slit-lamp. It will have a place for you to rest your chin and forehead. This will help keep your head steady during your exam. 15
Risks of Ophthalmoscopy Those afterimages should go away after you blink several times. In rare cases, you may react to the eye drops. This may cause: Dry mouth Flushing Dizziness Nausea and vomiting Narrow-angle glaucoma 16
Conclusion Ophthalmoscopy is an examination of the back part of the eye (fundus), which includes the retina, optic disc, choroid, and blood vessels. 17
