Summary

135 eyes of 135 patients treated between 2005 and 2017 will be included in this study. The diagnosis of functional epiphora was made based on a patent lacrimal system with a delay in the fluorescein dye disappearance test (FDDT) or dacryoscintigraphy (DSG) without any ocular surface or eyelid abnormalities. The absence of epiphora and normalization of FDDT postoperatively was defined as success. The study's hypothesis is that external DCR with a suitable technique will have better results compared to endonasal and transcanalicular DCR

Conditions

  • Functional Epiphora (Tearing Without Any Anatomical Block)

Interventions

PROCEDURE

External Dacryocystorhinostomy

The resistance of the lacrimal drainage is lowered by creating a new ostium between the lacrimal sac and nasal cavity via skin incision.

PROCEDURE

Endonasal Dacryocystorhinostomy

The resistance of the lacrimal drainage is lowered by creating a new ostium between the lacrimal sac and nasal cavity via endonasal route.

PROCEDURE

Transcanalicular Dacryocystorhinostomy

The resistance of the lacrimal drainage is lowered by creating a new ostium between the lacrimal sac and nasal cavity via transcanalicular route.
