Ophthalmoscopy or fundoscopy or retinal examination is a test which is used to examine the back of the eye including the optic nerve head (called optic disc), retina and major blood vessels.
Usually your eyes are first dilated by putting in eye drops at intervals of 5 – 10 minutes. This helps the eye doctor see the back of your eye better and ensures that when a light is shone onto it, your pupils (the hole in the coloured part of your eye) do not become smaller limiting the field of view. Time needs to be given for these eye drops to work, which means that you would be required to sit with your eyes closed for about 20- 30 minutes.
There are two types of Ophthalmoscopy – direct and indirect
In Direct Ophthalmoscopy, the eye specialist is able to see the retina directly. In Indirect Ophthalmoscopy, the eye doctor uses a hand-held lens or ophthalmoscope to view a magnified view of the eye. Sometimes, your eyes may not be required to be dilated before this test.
In Indirect Ophthalmoscopy, you may be required to lie down or recline as your eye specialist shines a bright light mounted on his forehead into your eye and examines the inside of your eye with a condensing lens. As compared to direct ophthalmoscopy, indirect ophthalmoscopy provides a wider, three dimensional view of the retina that is easier to interpret.
While the examination does not take more than ten minutes, you may experience blurry vision and sensitivity to light for a few hours till the effect of the drops wear off. This means that you will not be able to drive on your own and would require someone to drive you home.
Fundoscopy is often a part of routine investigations to detect conditions of the retina like:
