Giant papillary conjunctivitis in contact lens wearers
American Journal of Ophthalmology
|May 1, 1977
Summary
Giant papillary conjunctivitis (GPC) affects contact lens wearers, causing symptoms like itching and mucus. This immunologic syndrome, potentially triggered by lens deposits, can develop even after years of successful wear.
Area of Science:
- Ophthalmology
- Immunology
- Contact Lens Science
Background:
- A specific syndrome affects both hard and soft contact lens wearers.
- Characterized by increased mucus, itching, decreased lens tolerance, and giant papillae on the upper tarsal conjunctiva.
- Onset can be rapid (as few as three weeks) or delayed (months to years) after successful lens wear.
Purpose of the Study:
- To describe the clinical and histological features of a contact lens-related syndrome.
- To investigate the potential immunologic origin of the condition.
- To identify a significant cause of contact lens intolerance.
Main Methods:
- Clinical observation of contact lens wearers presenting with specific symptoms.
- Histological examination of conjunctival tissue.
- Analysis of cellular infiltration patterns in the epithelium and stroma.
Main Results:
- Histology revealed basophils, eosinophils, and mast cells in the epithelium.
- Increased lymphocytes, plasma cells, and polymorphonuclear leukocytes were found in the stroma.
- Deposits on contact lenses are suspected as the antigenic trigger.
Conclusions:
- The syndrome is likely immunologic in origin, with lens deposits acting as antigens.
- This condition may be a primary reason for developing contact lens intolerance.
- Understanding the immunopathology is crucial for managing contact lens complications.
