Using clinical information collected by questionnaires, patients were \ndivided into: 97 with ocular toxoplasmosis (group 1) and 98 with ocular lesions not due to \ntoxoplasma (group 2). The geometric mean of dye test titres (\u00b1<jats:sc>S.D.<\/jats:sc> natural log titre) in group 1 was 53\u00b72 (\u00b10\u00b795) compared with 24\u00b76 \n(\u00b11\u00b711) in group 2 (<jats:italic>P<\/jats:italic>&lt;0\u00b7001). Young females tended \nto have more active lesions compared with young males (<jats:italic>P<\/jats:italic>&lt;0\u00b705). There was an age-dependent difference in dye test titres between the groups (<jats:italic>P<\/jats:italic>&lt;0\u00b7001). Group 1 showed a \ndecline in titre with age compared with an increase in group 2. Ocular toxoplasmosis was \ndiagnosed most frequently among 21\u201330 year olds.
