Lacrimal system complications in trachoma

Area of Science:

• Ophthalmology
• Infectious Diseases
• Public Health

Background:

• Trachoma is a leading cause of preventable blindness globally.
• Lacrimal complications significantly impact patient quality of life and visual outcomes.
• Understanding these complications is crucial for effective management and prevention strategies.

Purpose of the Study:

• To investigate the prevalence and types of lacrimal complications associated with trachoma.
• To analyze the clinical and histopathological findings in patients with severe inactive trachoma.

Main Methods:

• A clinical study involving 579 Saudi Arabian patients was conducted.
• Patients were examined for clinical evidence of trachoma and its lacrimal complications.
• Histopathologic examination of lacrimal sac and conjunctival biopsies was performed.

Main Results:

• 446 (77%) patients exhibited clinical signs of trachoma.
• Severe inactive trachoma was observed in 62 patients.
• Common complications included dry eye syndrome, punctal phimosis/occlusion, canalicular occlusion, nasolacrimal-duct obstruction, dacryocystitis, dacryocystocele, and dacryocutaneous fistula.
• Histopathology revealed cicatrizing changes in both lacrimal sac and conjunctival biopsies.

Conclusions:

• Trachoma is highly prevalent in the studied Saudi Arabian population.
• Severe inactive trachoma is associated with a wide spectrum of debilitating lacrimal complications.
• The findings underscore the need for comprehensive management of trachoma to prevent severe ocular morbidity.
