Complications of the Strabismus (Squint) Surgery
• Undercorrection and overcorrection are the most
common "complications" noted after strabismus
• Perforation of the sclera : Perforation of the
globe may occur in 0.3% – 2.8% of cases [1,2],
resulting in endophthalmitis in less than 1:3500
[3,4], and retinal detachment in even fewer cases
• Lost and slipped muscles
• Postoperative diplopia
• Conjunctival granulomas and cysts
• Anterior segment ischemia
