Partial orbital lobe dacryoadenectomy (POLD) effectively reduces refractory epiphora in patients with lacrimal outflow obstruction. This safe, short-term surgical option showed significant symptom improvement without causing dry eye disease.

Area of Science:

  • Ophthalmology
  • Oculoplastics
  • Lacrimal Surgery

Background:

  • Refractory epiphora often results from proximal lacrimal outflow system obstruction.
  • Previous surgical interventions like dacryocystorhinostomy may fail, necessitating alternative treatments.

Purpose of the Study:

  • To evaluate the efficacy and safety of partial orbital lobe dacryoadenectomy (POLD) for treating refractory epiphora.

Main Methods:

  • A prospective interventional study was conducted at a tertiary eye care institute.
  • 17 patients with refractory epiphora underwent POLD under local anesthesia.
  • Preoperative and postoperative assessments included Munk score, Schirmer-I Score, tear breakup time, corneal staining, AS-OCT, and CT scans.

Main Results:

  • The study included patients with punctal agenesis, punctal effacement, and proximal bicanalicular obstruction.
  • POLD involved removing 50-60% of the orbital lacrimal gland lobe.
  • Significant reductions in Munk score (60%), Schirmer-I value (35.2%), and tear film height (35.9%) were observed at 3 months (P < 0.05).

Conclusions:

  • Partial orbital lobe dacryoadenectomy (POLD) is an effective and safe short-term treatment for refractory epiphora.
  • The procedure did not result in dry eye disease symptoms in the studied patients.
  • Long-term efficacy requires further investigation.
