The main prognostic factors influencing the results of the superior tarsal muscle resection in patients with blepharoptosis

Transconjunctival methods of ptosis correction gain popularity nowadays. The wide use of the technique is limited because of the lack of clear recommendations regarding the volume of the resection, especially in patients with negative phenylephrine test. Purpose. To assess the influence of main predictive factors on superior tarsal muscle (STM) resection result. Materials and methods. Patients were divided into two groups according to the result of phenylephrine test (PE). Patients with positive results were included in the first group, with negative and weak results in the second group. All patients underwent STM resection according our new algorithm. Results. The result of STM resection was influenced by PE test and intraoperative white line motility test (WLM), but not by levator function and the amount of superior tarsal muscle resection. Conclusions. PE and WLM tests play main role in choosing a method for blepharoptosis correcting.
