摘　　要：AIM:To compare the cup-to-disc ratio(CDR)and optic disc morphology between eyes with congenital cataract and eyes without cataract in children under 3 years old.METHODS:This study included 63 patients with bilateral congenital cataract(mean age of 55.72±46.50wk,44 were male),33 patients with unilateral cataract(mean age of 56.63±33.23wk,16 were male),and 31 age-matched healthy children(mean age of 55.80±29.29wk,17 were male).Fundus photographs were taken with the RetCam 3 system.The horizontal-to-vertical disc diameter ratio(HVDR)was used as an index to describe the oval form of the optic disc.RESULTS:The horizontal cup-to-disc ratio(HCDR),vertical cup-to-disc ratio(VCDR)and HVDR of cataract eyes in unilateral groups were significantly smaller than those of the normal eyes(P<0.05).In the unilateral group,the HCDR,VCDR and HVDR of cataract eyes were significantly smaller than those in fellow eyes(P<0.05).The HVDR of eyes in the bilateral group was significantly smaller than those in the age-matched normal eyes(P<0.001).The form of optic disc of the cataract eyes in both the bilateral and unilateral groups was more vertical-oral than the normal eyes in the unilateral and the age-matched groups(P<0.05).CONCLUSION:Our results show that eyes with congenital cataract has a smaller HVDR and the form of the optic disc tended to be vertical-oval in young children.
