| Popis: | Objective To evaluate the use of perforated punctal plugs with adjuvant application of mitomycin-C in the management of acquired external punctal stenosis grades 0 and 1. Methods This is a prospective interventional case series including 30 eyes of 30 patients with acquired external punctal stenosis of the lower punctum of grades 0 and 1 presenting with epiphora. They were examined to exclude other causes of lacrimation and epiphora: Slit-lamp assessment of the stenosed punctum and grading was done, probing was done to exclude associated canalicular stenosis, and syringing was done to exclude nasolacrimal duct obstruction. For all cases, dilatation was done, followed by application of mitomycin-C, and perforated punctal plugs were then inserted. Plugs were removed after 6 months, and anatomical and functional success were assessed and followed during and for 6 months after removal of the plugs. Results The study included 30 patients with acquired external punctal stenosis: 9 males (30%) and 21 females (70%) with a mean age of 62.83 ± 8.3 years. Punctal stenosis grade 0 (no punctum) occurred in 9 cases (30%), and grade 1 (the punctum is covered by a membrane) occurred in 21 cases (70%). Six months after removal of the plugs, epiphora improved in 93.3% of patients, and fluorescein dye disappearance test results improved in 90% of patients; 6.7% of cases had early extrusion of the plug, and 3.3% had granuloma formation. Conclusions Application of perforated punctal plugs combined with mitomycin-C is a simple and efficient technique in the management of tight acquired external punctal stenosis. |
