Prevalence of cataract (including aphakia or pseudophakia) and glaucoma (definite cases) in men and women. Cataract is defined as lens opacity causing visual impairment (visual acuity <6/12) in one or both eyes

Age and sex	Cataract			Glaucoma
	Prevalence (%) (No of cases)	Prevalence ratio women:men		Prevalence (%) (No of cases)	Prevalence ratio women:men
65-69:
Women	17 (36/213)	1.08		1 (3/213)	0.81
Men	16 (27/173)			2 (3/173)
70-74:
Female	27 (64/238)	1.27		2 (5/238)	0.76
Male	21 (38/180)			3 (5/180)
75-79:
Female	44 (85/195)	1.3		2 (3/195)	0.36
Male	39 (55/142)			4 (6/142)
80-84:
Female	64 (101/159)	1.32		3 (4/159)	0.32
Male	48 (37/77)			8 (6/77)
85-100:
Female	76 (90/119)	1.29		8 (9/119)	1.29
Male	59 (30/51)			6 (3/51)
All:
Female	41 (376/924)	1.36		3 (24/924)	0.70
Male	30 (187/623)			4 (23/623)
All	36 (563/1547)			3 (47/1547)

CATARACT: Age adjusted summary prevalence ratio^*=1.22 (95% confidence limits 1.07-1.40, P value 0.003) 

Test of equal prevalence across the age groups: P value=0.88 (indicates no effect of modification by age) 

^*Remains highly significant after further adjustment for possible confounding effect of “ethnic origin” 

GLAUCOMA: Age adjusted summary prevalence ratio^**=0.70 (95% confidence limits 0.35-1.10, P value 0.13) 

Test of equal prevalence across the age groups: P value=0.53 (indicates no effect modification by age) 

^**Slightly reduced (to 0.63, not significant) after further adjustment for possible confounding effect of “ethnic origin”
