FP1593 : Outcomes of ptosis surgery in patients with monocular elevation deficit (MED)

Dr. Tarjani Dave (D13684)

Purpose: The demographics, clinical presentations and treatment outcomes of ptosis surgery in 89 patients with monocular elevation deficit and ptosis

Methods: Retrospective review of cases to analyse the pre and post palpebral fissure height (PFH), margin reflex distance1 (MRD1), levator action(LPSA), type of ptosis surgery and complications. Acceptable result consisted of MRD1 of < 1 mm between the two eyes

Results: Median age was 15 years. Males were 59.6%(p=0.01). Ptosis was mild in 77(86.5%) eyes, moderate in 8(9%) and severe in 4(4.5%). Associated marcus gunn jaw winking was seen in 39.33%. Prior squint surgery was done in 53(59.6%)eyes the commonest being inferior rectus recession. Tarsofrontal sling(TFS) surgery was done in 64(71.91%) and levator resection(LPSR) in 25(28.09%). Mean pre op PFH was 5.1+2.19mm and post opt was 8.25+1.79mm(p<0.0001). The mean difference between the MRD1 in operated and fellow eye was 0.69 mm in TFS and 2.3mm in LPSR group.

Conclusions: Marcus Gunn is a frequent association of congenital ptosis
