Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In our study, we would like to find the efficacy of nasolacrimal duct intubation, which was performed in our medical center on a few hundred patients with mild epiphora.
Study hypothesis: nasolacrimal intubation in adults, with a clinically mild epiphora, is close in it's efficacy to the Dacryocystorhinostomy procedure.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. Dacryocystorhinostomy - surgery for reconstructing an alternative path for tear drainage.
2. Nasolacrimal intubation - inserting a silicone tube through the tear duct. The tube is usually removed after 3-6 months.
Currently, there are only a few reports regarding the efficacy of nasolacrimal intubation, all with a small number of research subjects. Also, these reports have stratified the patients according to the location of the tear duct blockage, and didn't take into account the severity of the blockage (ie the severity of symptoms) prior to performing the intubation.
In our research, we would like to find the efficacy of nasolacrimal intubation which was performed in our medical center on a few hundred patients with mild epiphora, and to compare in with the efficacy of the Dacryocystorhinostomy - which is 80-90% according to literature.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Primary
All the patients in our medical center who underwent nasolacrimal intubation, due to mild epiphora, during the years 2000-2007.
Silicone tube
Silicone tube which is inserted into the tear duct through the punctum in the eyelid, then passed through the tear duct till it enters the nose and secured in place using a surgical knot. The tube remains in place for 3-6 months, than take out by the surgeon.
Interventions
