Lacrimal Deroofing for Epiphora From Punctal Abnormalities

Purpose: To report outcomes of proximal lacrimal deroofing in the management of proximal lacrimal drainage system abnormalities.

Inclusion criteria

At least 18 years old patients with lacrimal punctum stenosis and/or canaliculitis.

Exclusion criteria

Trauma, Thyroid eye disease, lacrimation and other causes of epiphora.

Evaluation: All patients underwent a comprehensive ophthalmic examination, and lacrimal drainage evaluation at baseline,2 weeks and 6 months after the surgery.

Outcome Measures:

Munk scale for epiphora grading (0-5); 0 No epiphora ,1 Epiphora requiring dabbing less than twice a day, 2 Epiphora requiring dabbing 2-4 times a day, 3 Epiphora requiring dabbing 5-10 times a day, 4 Epiphora requiring dabbing more than 10 times a day, 5 Constant epiphora.

Grading of External Lacrimal Puncum (0-5); score 0: No papilla and punctum (punctal atresia); surgery to create a papilla, score1: Papilla is covered by a membrane; a #25 needle, followed by a punctal finder. Exudative or true membrane or fibrosis, difficult to recognize with standard punctum dilator, score 2: Less than normal size, but recognizable; a punctal finder and, then a standard punctum dilator required, score 3: Normal; regular punctum dilator required, score 4: Small slit (< 2 mm); no intervention required, score 5 Large slit (≥ 2 mm); no intervention required.

Inclusion criteria

• epiphora due to lacrimal punctum stenosis and/or canaliculitis.

Exclusion criteria

• Trauma, Thyroid eye disease, lacrimation and other causes of epiphora.
