The relation between biomechanical parameters of upper eye lid tissues and clinical features of ptosis.
Biomechanical parameters of upper eyelid tissues (skin, levator, orbicular muscle of the eye) in congenital and acquired ptosis of various geneses are studied. The analysis of biomechanical testing of samples obtained during reconstructive treatment of 87 patients aged 3-81 (43 children and 44 adults) with congenital, post-traumatic, senile (combined with blepharohalasis) and myopathic ptosis revealed the dependence of the changes of biomechanical parameters on the patient's age, form and severity of ptosis. // Russian Ophthalmological Journal, 2012; 2:63-67.
