Abstract：【Objective】To investigate the corneal morphology and astigmatism in different age groups of moderate and severe congenital ptosis and analyze the relationship between ptosis and age.【Methods】Eighty-three cases (114 eyes) of moderate and severe congenital blepharoptosis diagnosed by ophthalmology in Hunan Children's Hospital were collected in detail and examined by ophthalmology. According to the age of the children, they were divided into two groups: group A ( 3 ≤ age<5) and group B ( 5 ≤ age<12). The corneal morphology and astigmatism of patients with blepharoptosis at different ages were analyzed, and the differences of corneal morphology and astigmatism among patients with blepharoptosis at different ages were compared.【Results】In 114 eyes, there was no significant difference in corneal astigmatism 〔Cyl (D)〕, surface rule index (SRI), surface asymmetry index (SAI) and total astigmatism of retina [C (D)]in patients with different degrees of ptosis in the same age group (P>0.05). The results of preoperative corneal topography showed that the ratio of inverse rule and oblique astigmatism increased with age, and the difference was statistically significant (P<0.05). In the moderate blepharoptosis group, there were 37.0% children with conformable astigmatism, 25.9% with reverse astigmatism, 37.0% with oblique astigmatism. In the severe blepharoptosis group, 65.0% of children with conformable astigmatism, 11.7% of converse astigmatism and 22.3% of oblique astigmatism, there was significant difference between the two groups (P<0.05).【Conclusion】Children with ptosis increase with age.The proportion of oblique and inverse astigmatism increased with age, but there was no significant correlation with the degree of blepharoptosis. It is suggested that eyelid surgery should be performed at the age of 3 and 5 years, and refractive correction should be performed after operation.
