Is pupil dilation required for fundus photography?

Whether pupil dilation is needed for fundus photography depends on individual circumstances.

Fundus photography is a method of examining and recording the structural condition of the retina using a fundus camera. Clinically, there are two types: dilated and non-dilated fundus photography. Dilation involves using medication to enlarge the pupil, allowing a clearer view of the fundus. However, in cases of cataracts, glaucoma, or pupillary adhesions, dilation is generally not recommended, as it may increase intraocular pressure and lead to optic nerve atrophy. On the other hand, if a child has a clear lens and signs of retinal abnormalities are observed, dilation is usually necessary to prevent missed diagnoses.

After dilation, a recovery period is required, during which excessive eye use should be avoided.
