Prevalence of Amblyopia in Children with Congenital Ptosis
Downloads
Objective: To evaluate amblyopia and its causes in a sample of Iraqi patients with congenital ptosis.
Methods: The study was conducted at the Ophthalmology Clinic of Ibn Al-Haytham Eye Teaching Hospital from May 2012 to February 2013. Only cases with true congenital ptosis were included. Uncooperative children were excluded. Patients underwent amblyopia assessment and a complete ophthalmic examination.
Results: Of 60 eyes out of 53 cases, amblyopia was found in 13 (21%). The causative factors for amblyopia were refractive errors: 8 eyes (61%), strabismus: 4 eyes (31%), and stimulus deprivation: 1 eye (8%). The incidence of amblyopia increases with increasing extraocular abnormalities.
Conclusion: Patients with congenital ptosis are at high risk for developing amblyopia. Therefore, regular screening is recommended from the onset of the disease.
