Outcomes of Posterior Approach Ptosis Surgery

Abstract

Objective: To assess surgical outcomes of posterior approach ptosis surgery i.e., Conjunctivo-Muller resection for mild to
moderate simple congenital ptosis.

Study Design: Quasi Experimental Study.

Place and Duration of Study: Orbit and Oculoplastic Department, Armed Forces Institute of Ophthalmology, Rawalpindi
Pakistan, a tertiary care ophthalmic facility for a period of 6 months from May to Dec 2022.

Methodology: A sample size of 22 was calculated. Data containing patient’s age, gender, pre-op MRD-1, upper lid crease, postOp MRD 1, inter-eye palpebral fissure height symmetry, post-Op Complications were documented on Microsoft Excel Sheet.

Results: Out of total 22 patients, 10(45%) were male and 12(55%) were females. There was a significant improvement in postoperative MRD1 a mean of 1.25±0.33 mm. The mean pre-Operative MRD 1 was 2.72±0.48 mm while mean post-Operative MRD 1 was 3.97±0.36 mm

Conclusion: Posterior approach blepharoptosis repair is a safe and effective method for correction of mild to moderate simple congenital ptosis provided a good case selection especially if patient has fair pre-operative upper lid crease. The surgery has an acceptable cosmetic outcome as there would be no scar mark on eyelid skin. Furthermore, for moderate to severe ptosis the procedure can be opted as an initial surgical trial depending on case-to-case basis.
