This is a process that allows for the photography of retinal and ocular structures.
As part of an eye examination the optometrist will examine the anterior eye (including the cornea and lens) and also examine posterior surface of the eye i.e. the retina using slit lamp biomicroscopy or direct ophthalmoscopy.
What you need to do
If there are any abnormalities of the retina then these historically would be noted into your file and monitored visually each year by the optometrist, or referred on for ophthalmological review.
Advances in technology now allow us to use digital retinal photography to document the retinal surface at each visit. These photographs can then be compared side by side at each visit and any small changes or abnormalities can be more readily identified. Again this is a quick, painless process and can be performed with or without the use of mydriatic drops (drops to make the pupil larger).
Digital Retinal Photography is also required and or used for Diabetic retinopathy screening.
