Purpose:
|
To determine the prevalence of ptosis (congenital/ acquired) in 7-year-old Iranian children and its relationship with amblyopia and strabismus
|
|
Methods:
|
Eight Iranian cities were selected for this cross sectional study using multistage randomized cluster sampling. A number of primary schools were randomly selected in each city. All grade one students in each selected primary school underwent optometric examinations including the measurement of uncorrected and corrected visual acuity, cover test, and cycloplegic and non-cycloplegic refraction
|
|
Results:
|
Of 4614 selected students, 4106 students participated in the study (response rate=89%). The prevalence of ptosis (congenital/ acquired) was 1.41% (95% CI 1-1.83); 0.49% (95% CI 0.26-0.72) and 0.93% (95% CI 0.59-1.26) had unilateral and bilateral ptosis, respectively. The prevalence of ptosis had no significant correlation with sex (p=0.810, OR=1.07, 95% CI 0.59-1.97). The prevalence of amblyopia was 48.28% and 0.89% in students with and without ptosis, respectively. The prevalence of tropia was significantly higher in cases with bilateral ptosis (p<0.001).

|
Conclusion:
|
We report the prevalence of ptosis (congenital/ acquired) in children in Iran and the Middle East region for the first time. Amblyopia was considerably more prevalent in ptotic patients. We found a significant correlation between ptosis and tropia
