Certified Ophthalmic Medical Technologist (COMT) Practice Exam

When keratoconjunctivitis sicca and xerostomia occur together, it is referred to as?

1. Sjögren's syndrome

2. Raynaud's phenomenon

3. Lupus erythematosus

4. Hashimoto's thyroiditis

The correct answer is: Sjögren's syndrome

The correct answer is Sjögren's syndrome, which is an autoimmune condition primarily characterized by the destruction of exocrine glands, leading to dry eyes (keratoconjunctivitis sicca) and dry mouth (xerostomia). In Sjögren's syndrome, the body's immune system mistakenly attacks the moisture-producing glands, resulting in significant discomfort and difficulties with vision and swallowing due to the lack of lubrication. This condition often presents in individuals with other autoimmune disorders, making it important for diagnosis and management. The relationship between keratoconjunctivitis sicca and xerostomia is a key clinical feature that prompts healthcare providers to consider Sjögren's syndrome in their differential diagnoses. It is essential for students in ophthalmic technology to recognize this connection as it has implications for treatment strategies and patient care management in individuals experiencing these symptoms.
