Which tests are used to evaluate canaliculitis?

• A. NaFl and punctal expression
• B. Intraocular pressure and visual acuity
• C. Color vision and visual field
• D. Fundus examination and OCT

Answer: (A)

Evaluation of canaliculitis focuses on the lacrimal drainage pathway. Using sodium fluorescein helps visualize how dye moves through the tear drainage system, revealing patency issues or leaks along the canaliculi. Punctal expression involves gently expressing material from the punctum to obtain purulent discharge or concretions, which is highly characteristic of canaliculitis. Together, these tests directly assess the site of infection and its drainage pathway. Other tests listed assess vision or the posterior segment and do not address the lacrimal drainage system or canalicular infection.
