Abstract Details


Synthetic sling materials do not bio-integrate. Recurrence and revision surgeries required are mostly due to the migration of sling material in the eyelid in spite of suture fixation currently being practised. We expect tarsal tunnel to provide better tarsal fixation.


Rajendra Prasad Centre for Ophthalmic Sciences, AIIMS, New Delhi


In a prospective randomised interventional pilot study, 30 patients with simple severe congenital ptosis, of age > 3 years were divided into 2 groups of tarsal tunnel and suture fixation. Follow-up period: 6 months. In one group the sling was fixed to tarsus using suture, in the other by passing sling material through a tunnel made in tarsus using MVR blade.


Baseline, as well as post-op outcomes in terms of subjective satisfaction and objective outcomes based on a vertical palpebral aperture in primary gaze, residual ptosis, lid fold asymmetry and MRD1, were comparable. Lagophthalmos was significantly less in tunnel group.


The new technique of tarsal tunnel fixation is comparable to the conventional technique in terms of complications, outcome and patient satisfaction.
