Trachoma is a chronic infectious conjunctivitis and keratitis caused by Chlamydia trachomatis, which can lead to blindness. During the acute phase in both eyes, symptoms include redness, pain, foreign body sensation, tearing, and purulent discharge, along with swollen lymph nodes, increased papillary formation in the palpebral conjunctiva, and multiple follicles covering the superior and inferior fornices. After the acute phase, which lasts one to two months, it enters a chronic phase where conjunctival congestion decreases, and the conjunctiva thickens with increased papillary and follicular formation. Complications in the later chronic stage mainly include entropion and trichiasis, eyelid ptosis, symblepharon, essential keratoconjunctivitis sicca, and chronic dacryocystitis leading to corneal opacity, among others.
