Abstract

Aims and Purpose The aim of this study was to describe the prevalence and characteristics of drusen and pigmentary changes in a middle-aged population.

Methods Retinal images from 500 individuals aged 18–54 years were included. The source of participants was two UK optometry practices. Retinal images were graded using the Wisconsin Age-Related
Maculopathy Grading System. However, owing to the relatively young age of the population studied, a new category of drusen of smaller size (o31.5mm) was introduced.

Results Drusen were identi?ed within the central macular grid in 91.48% of all gradable eyes and in 444 subjects. Drusen sized o31.5mm were present in 89.7% of eyes, drusen sized 431.5mm and o63mm were present in 45.9% of all eyes and drusen 463mm and o125mm were present in only 1.7% of eyes. No eye had drusen larger or equal to 125mm. Very few eyes (1.2%) showed pigmentary changes within the grid. Drusen load increased with increasing age, P o0.001.

Conclusions The frequency of drusen in a younger Caucasian population aged 18–54 years is high, with 91.48% of all gradable eyes having drusen. The most frequent drusen subtype was hard distinct drusen o31.5mm. No druse greater or equal in size to 125mm was seen. Pigmentary changes are rare.
