Table 5Mydriasis with tropicamide

Mydriasis with tropicamide:
  • reduces the failure rate (inadequately interpretable photographs) in around 5% of eyes of people with diabetes (in particular in the second eye and in the elderly), and thus the need for recall for a further examination when tropicamide will be necessary
  • allows follow-up ophthalmoscopy to be optimised reducing false-negative referrals to ophthalmologists
  • carries no detectable risk to the eye except in the post-surgical period
  • is briefly uncomfortable (stings)
  • paralyses accommodation (near vision) and pupil constriction for 30–60 minutes (low dose), but in some people for much longer, giving problems with glare and bright light sufficient to impair vision to unsafe levels for some tasks (for example driving).
