Canaliculitis: Too Often Underdiagnosed?

Area of Science:

• Ophthalmology
• Otorhinolaryngology

Background:

• Canaliculitis is often misdiagnosed or underdiagnosed, leading to delayed and inadequate treatment.
• Characteristic clinical signs of canaliculitis are frequently overlooked, contributing to diagnostic challenges.

Purpose of the Study:

• To determine the diagnostic delay and frequency of misdiagnosis in canaliculitis.
• To identify characteristic clinical features of canaliculitis.
• To evaluate the outcomes of surgical management for canaliculitis.

Main Methods:

• Analysis of 13 patients with 17 affected canaliculi.
• Data collection included demographics, affected canaliculus, symptom duration, and prior treatments.
• Histological assessment for Actinomyces species in removed concretions.

Main Results:

• Mean symptom duration before diagnosis was 14 months; 92% of patients became symptom-free post-surgery.
• Surgical canaliculotomy was performed on all 17 affected canaliculi, remaining patent in all cases.
• Actinomyces species were identified in 73% of concretions, supporting their role in canaliculitis.

Conclusions:

• Canaliculitis requires increased awareness and recognition of typical signs to avoid misdiagnosis.
• Surgical canaliculotomy is effective for removing bacterial concretions and should be the treatment of choice.
• Timely surgical intervention leads to complete symptom resolution and prevents recurrence.
