Which of the following is NOT listed as an indication for doxycycline in ophthalmic use?

• A. Acne Rosacea
• B. Glaucoma
• C. Dry Eyes (MGD)
• D. Chlamydia conjunctivitis

Answer: (B)

Doxycycline in ophthalmology is used for inflammatory lid disease and certain infections due to its antimicrobial and anti-inflammatory effects. It helps with ocular rosacea and blepharitis/MGD by reducing lid-margin inflammation and improving meibomian gland function, and it treats chlamydial conjunctivitis as well. These indications rely on its ability to curb inflammation and bacterial activity in the eyelids and anterior segment. Glaucoma, however, is a condition of the optic nerve related to intraocular pressure and is managed with IOP-lowering medications or procedures; doxycycline does not address IOP or optic nerve damage. Therefore, glaucoma is not an indicated use for doxycycline in ophthalmic practice.
