“…When compared with the previously reported surgical success rates of congenital ptosis surgeries, ranging from 47% to 93%,8–14 the IOLF seems to yield promising surgical results. Recently, an Egyptian study group used the IOLF for levator resection in 20 eyelids of 17 patients with congenital ptosis involving LF ≥4 mm and reported a satisfactory outcome of up to an 80% success rate 15. In the present study of 30 eyelids of 22 patients, we also confirmed the usefulness of the IOLF based on LF: the success rate was 100% (n=19/19) in eyelids with LF ≥5 mm, versus 72.7% (n=8/11) in eyelids with LF normal≤ 4 mm.…”

“…Various methods are available to calculate the amount of levator resection based on levator function, MRD1 and intraoperative lagophthalmos [ 4 ]. However, to the best of our knowledge, there is no formula specifically tailored for the levator muscle plication technique.…”

Aim to assess the outcomes of a novel algorithm for the calculation of the amount levator muscle plication in congenital blepharoptosis surgery. Methods this retrospective comparative study included 34 patients with congenital ptosis subjected to levator muscle plication surgery during the period from October 2021 to November 2022. They were divided into two groups. Group A: the amount of levator muscle plication was calculated by a traditional formula [(amount of ptosis x 3) + 9 mm in cases with good levator function or (amount of ptosis x 3) + 11 mm in cases with fair levator function]. Group B: the amount of levator muscle plication was calculated by a novel nomogram [the result of the traditional formula was modified by subtracting 4 mm if the calculated amount was ≥ 15 mm or subtracting 3 mm if the calculated amount was < 15 mm]. Demographic data, baseline ptosis characteristics and postoperative results at 1st week, 1st month, 3rd month and 6th month were compared between the groups. Primary outcome measure was postoperative Marginal Reflex Distance (MRD1). Secondary outcome measures were lid contour, lid crease and any reported complications. Results Group A included 20 eyes of 18 patients while Group B included 20 eyes of 16 patients. The mean amount of levator muscle plication was 16.98 ± 2.44 mm and 13.48 ± 2.42 mm in group A and group B respectively. The difference between the two groups was highly statistically significant (p < 0.001). Mean MRD1 at the 1st postoperative week was 4.95 ± 0.37 mm in group A and 4.08 ± 0.64 mm in group B. This difference was highly statistically significant (P < 0.001). Overcorrection was seen in 8 (40%) eyes in group A and 1 (5%) eye in group B. The difference was statistically significant between the two groups (p = 0.008). Undercorrection was seen in only 1 (5%) eye in group B. No other complications were reported. Surgical success was achieved in 12 (60%) eyes in group A versus 18 (90%) eyes in group B. The difference between the two groups was statistically significant (p = 0.03). Conclusion our novel nomogram for the calculation of the amount levator muscle plication in congenital blepharoptosis surgery is effective in achieving a satisfactory postoperative MRD1.

Purpose: To investigate the surgical outcomes of maximum Levator resection in cases of severe upper eyelid ptosis at a tertiary oculoplastic service. Study Design: Interventional case series. Place and Duration of Study: Department of Ophthalmology, Lady Reading Hospital, Medical Teaching Hospital, Peshawar January 2013 to December 2017. Methods: One hundred and twenty three eyes of 107 patients, who underwent maximum levator resection for severe congenital ptosis were included. Patients with missing or incomplete notes, patients with previous ptosis surgery and ptosis other than congenital were excluded. Maximum levator resection of the muscle above the Whitnall ligament was performed under local/general anesthesia. All patients had a minimum of 6 months and maximum of 5 years followup. The postoperative complications were recorded and followed. Post operative followup was done at day one, week one and at four weekly intervals till the end of the study. Results: Out of 123 eyes, satisfactory results (excellent or good) were obtained in 111 (90.1%) eyes. Majority of the patients (56.09%) were females. Mean Preoperative Levator function was 2.3 ± 1.1mm. Mean Preoperative MRD1 was ?0.1 ± 1.5 mm and mean postoperative MRD1 was 3.9 ± 01.0 mm. The commonest complication was over correction which occurred in 5 (4.06%) cases, under correction in 4 (3.25%), crease abnormality in 2 (1.62%) cases and entropion was seen in only one (0.81%) case. Success rate was 90.1% at 6 months to 5-years followup. Key Words: Blepharoptosis; Levator resection; Levator function.
