Summary
Minimally invasive surgery using RS-type silicone tubes effectively treats chronic canaliculitis, offering high success rates and a safe alternative to traditional methods.
Area of Science:
- Ophthalmology
- Oculoplastics
- Lacrimal Surgery
Background:
- Primary chronic canaliculitis (PCC) presents a challenge in treatment.
- Conventional surgical techniques may involve more invasive procedures.
Purpose of the Study:
- To evaluate the efficacy of a minimally invasive punctum-preserving canaliculotomy with RS-type silicone tube intubation for PCC.
- To assess both anatomical and functional outcomes of this surgical approach.
Main Methods:
- A retrospective study of 55 patients (55 eyes) with PCC.
- Procedure involved punctum dilation, curettage, irrigation, and RS tube intubation.
- Outcomes assessed over 12 months included anatomical patency and absence of epiphora.
Main Results:
- High success rates: 98.2% anatomical success and 94.5% functional success.
- All surgeries completed under local anesthesia within 30 minutes.
- No procedural complications were reported, with resolved inflammation in all patients.
Conclusions:
- Minimally invasive punctum-preserving canaliculotomy with RS tube intubation is a safe and effective treatment for PCC.
- This technique offers a promising alternative to conventional treatments.
- Further prospective trials are recommended to confirm these findings.
