Occlusion/stenosis of nasolacrimal
Congenital occlusion of the lacrimal system
The neonatal lacrimation is usually due to incomplete conformation of the lower part of the lacrimal system. The final maturation and cutting of the nasolacrimal pore complete during their birth or in the first months of neonatal life. The patency is restored until the first year of life.
Symptoms
- Intense constant lacrimation
- Intense mucus secretions and occasionally purulent
- Full lacrimal ‘lake-like’ that gives the feeling of an eye ready to tear
Treatment: Finger massages and antibiotic eye drops in case of infection until the 9th are recommended. If the patency is not restored until that age, catheterization and washing of the system is being attempted. In persistent stenosis a catheterization is being performed with silicone tubes, which remain for a period of up to 6 months. In case of failure of all the above or when there is absolute occlusion of the nasolacrimal pore an ascornostomy is performed in cooperation with an otorhinolaryngologist.
Other congenital occlusion disorders include the membrane occlusion of the lacrimal spots and the agenesis or stenosis of the lacrimal tubes.
