Nontraumatic corneal perforation

Area of Science:

• Ophthalmology
• Corneal Diseases
• Surgical Outcomes

Background:

• Nontraumatic corneal perforations represent a significant cause of vision loss.
• Identifying predisposing factors and evaluating treatment efficacy are crucial for managing these severe ocular conditions.

Purpose of the Study:

• To investigate the predisposing conditions, treatment strategies, and visual outcomes associated with nontraumatic corneal perforations.
• To analyze the effectiveness of different management approaches, including penetrating keratoplasty, tissue adhesive, and medical therapy.

Main Methods:

• Retrospective chart review of nontraumatic corneal perforations.
• Analysis of cases with a minimum of 3 months follow-up.
• Data collected from January 1992 to December 1998 at the Cornea Service Wills Eye Hospital.

Main Results:

• Forty cases of nontraumatic corneal perforation were analyzed, with 62% affecting females.
• The most common associated conditions included keratoconjunctivitis sicca (30%), bacterial keratitis (15%), exposure keratopathy (12.5%), and herpes simplex virus keratitis (10%).
• Visual acuity improved by at least two Snellen lines in 37.5% of eyes treated with penetrating keratoplasty, 35.7% with tissue adhesive, and 8.3% with medical treatment, though treatment modality was not significantly related to final visual outcome.

Conclusions:

• Keratoconjunctivitis sicca is the leading underlying disease linked to nontraumatic corneal perforation.
• Successful management of corneal perforations can be achieved with tissue adhesive, medical therapy, or penetrating keratoplasty.
• Treatment selection is guided by the specific characteristics of the corneal perforation and the visual potential of the affected eye.
