 The fundus camera is an instrument used for fundus
photography, capable of illuminating and imaging the retina

the retina, optic nerve head, macula, retinal blood vessels,
choroid, and the vitreous.

10. Possible difficulties
during fundus Camera

 Musculoskeletal diseases may not allow the patient to keep the
chin in the chin rest.
 Severe photophobia in conditions like an acute ocular injury
may cause blepharospasm and increased lacrimation, creating
a challenge for a good capture.
