Table 3 Classification of retinal points by pigment, drusen size and autofluorescence pattern.

Pigment	Drusen size	Autofluorescence, number (%)
		Normal	Hypo	Hyper
Presence*	No drusen	56 (83.6)	7 (10.4)	4 (6.0)
	Intermediate	3 (100.0)	0 (0.0)	0 (0.0)
	Large	66 (72.5)	1 (1.1)	24 (26.4)
Absence†	No drusen	389 (93.5)	11 (2.6)	16 (3.8)
	Small	32 (100.0)	0 (0.0)	0 (0.0)
	Intermediate	26 (96.3)	0 (0.0)	1 (3.7)
	Large	125 (79.6)	11 (7.0)	21 (13.4)

*None of the points with pigment had small drusen; p = 0.0015; †p<0.0001.

Small drusen <63 μ; intermediate drusen 63–125 μ; large drusen >125 μ.

Hyper, Increased autofluorescence; Hypo, decreased autofluorescence.
