Abstract
Aim: To evaluate results of transconjuncunctival muller’s muscle resection for congenital ptosis with phenylepherine test.
Methods: This was a prospective study carried out at a tertiary care center in Central India. All patients with mild to moderate congenital ptosis were enrolled and any patient with previous surgery and corneal pathologies were excluded. MRD1, MRD2, amount of ptosis, Levator palpebrae superioris action and effect of phenylephrine test was noted. Graded transconjuctival muller’s muscle resection was performed. Pre-operative and post-operative parameters were compared. Data tabulated and analysis done.
Results: In the present study, total 21 patients were included with age ranging from 7 years to 26 years. In 12 cases only right eye was involved and in 9 cases left eye was affected. Female preponderance was observed. Average amount of ptosis was 2mm, average amount of phenylephrine improvement was 1.52mm. Muller muscle resection was carried out as 6 mm in 8 cases, 8 mm in 11 cases and 10 mm in 2 cases, each respectively. Levator palpebral superioris muscle action was in range from 8 mm to 15 mm with average of 10 mm. None of the cases required resurgery.
Conclusion: The study concluded that muller’s muscle transconjunctival surgery is very predictable surgery for mild to moderate ptosis with good levator function. Phenylephrine test helps to decide the plan and increases the predictability.
