Introduction:

Congenital nasolacrimal duct obstruction (CNLDO) is a common condition in infants characterized by the blockage of the tear drainage system. The Crigler technique, also known as the Crigler massage or Crigler digital massage, is a non-surgical treatment approach used to manage CNLDO. This comprehensive article aims to provide a thorough understanding of the Crigler technique, including its purpose, procedure, effectiveness, and safety.

Understanding the Crigler Technique:

The Crigler technique is a simple and non-invasive method used to relieve the obstruction in the nasolacrimal duct, allowing proper drainage of tears from the eye. It involves the application of gentle pressure and massage to the area around the lacrimal sac, promoting the flow of tears through the nasolacrimal system.

Procedure:

The Crigler technique can be performed by following these steps:

1. Preparation: Ensure proper positioning of the infant, with the head slightly tilted backward.
2. Cleanliness: Wash hands thoroughly and ensure a clean environment to minimize the risk of infection.
3. Technique: Using the index finger or a cotton swab, apply gentle pressure to the area located between the inner corner of the eye and the bridge of the nose, where the lacrimal sac is located. Apply rhythmic and gentle downward strokes or circular motions for approximately 10-20 seconds.
4. Frequency and Duration: Repeat the massage technique three to four times a day, preferably before feeding or when the baby is calm. Continue the technique for several weeks or until the obstruction resolves.

Effectiveness and Safety:

The Crigler technique has been widely used as a first-line treatment for CNLDO and has shown varying degrees of effectiveness. Some infants may respond well to the technique, experiencing gradual improvement and resolution of symptoms, while others may require additional interventions such as nasolacrimal duct probing or surgery.

It is important to note that the Crigler technique should be performed gently and with caution to avoid causing discomfort or injury to the infant. Parents or caregivers should be educated on the proper technique and instructed to seek medical attention if the obstruction persists or if signs of infection, such as redness or swelling, develop.

Conclusion:

The Crigler technique is a non-surgical treatment option for congenital nasolacrimal duct obstruction in infants. While it may be effective in some cases, its success can vary, and additional interventions may be necessary. It is important for healthcare providers to educate parents or caregivers on the proper technique and closely monitor infants with CNLDO for signs of improvement or the need for further intervention.
