Management of Conjunctival Concretions
Symptomatic conjunctival concretions should be removed via mechanical extraction using a needle or chalazion curette under topical anesthesia, while asymptomatic concretions require no treatment.
Treatment Algorithm
Asymptomatic Concretions
- No intervention required - observe only
- These calcified deposits are benign and do not affect vision or ocular health when not causing symptoms
Symptomatic Concretions (causing irritation, foreign body sensation, or ocular surface damage)
Mechanical removal is the definitive treatment:
Primary technique: Use a small chalazion curette under topical anesthesia with the patient supine 1
- Provides superior eyelid stability and visibility
- Minimizes risk if patient moves unexpectedly
- Allows gentle curettage of multiple exposed concretions simultaneously
Alternative technique: Direct needle extraction at the slit lamp
- Traditional approach for individual concretions
- May be less stable for managing copious lesions
Clinical Approach
Step 1: Identify symptomatic vs asymptomatic lesions
- Symptomatic patients report foreign body sensation, irritation, or tearing
- Examine for exposed concretions protruding through conjunctival surface
- Assess for secondary corneal abrasion from mechanical irritation
Step 2: For symptomatic cases, perform removal
- Apply topical anesthetic (e.g., proparacaine)
- Position patient supine for optimal control
- Use chalazion curette to gently scrape away exposed concretions 1
- Multiple concretions can be addressed in single session
Step 3: Post-procedure management
- Topical antibiotic prophylaxis may be considered to prevent secondary infection
- Artificial tears for comfort
- Follow-up only if symptoms persist
Important Caveats
- Do not confuse with lacrimal canaliculitis concretions - these require different surgical approaches (canaliculotomy) and are located in the lacrimal drainage system, not the conjunctiva 2
- Conjunctival concretions are degenerative deposits, not infectious
- Recurrence is possible but uncommon after proper removal
- The curettage technique described by 1 represents a practical advancement over traditional needle extraction for managing multiple lesions
