Introduction

Complications of trachoma include entropion and trichiasis, ptosis, symblepharon, and corneal opacity. Trachomatous damage to the tarsal plate leads to tarsal thickening and deformation, resulting in entropion and trichiasis. Trachoma-induced thickening of the conjunctiva and tarsal plate can cause ptosis. Scarring and contraction of the conjunctiva due to trachoma shorten the tissue, leading to symblepharon. Chlamydia trachomatis causes epithelial keratitis, which results in corneal opacity.

Complications of trachoma include entropion and trichiasis, ptosis of the upper eyelid, symblepharon, corneal opacity, etc.

1. Entropion and trichiasis: If not treated promptly and effectively, trachoma damages the tarsal plate, causing thickening and deformation of the tarsus, along with scarring and contraction of the conjunctiva, leading to entropion and trichiasis.

2. Ptosis of the upper eyelid: Trachoma causes thickening of the conjunctiva and tarsal plate, increasing the weight of the eyelid, which damages the muscles and weakens the function of eyelid elevation, resulting in ptosis.

3. Symblepharon: Scarring and contraction of the conjunctiva caused by trachoma shorten the palpebral conjunctiva, leading to symblepharon.

4. Corneal opacity: Chlamydia trachomatis causes epithelial keratitis, forming corneal pannus; additionally, trichiasis irritates the cornea, contributing to corneal opacity.

In addition, if trachoma is not treated promptly and effectively, it may also lead to parenchymatous conjunctival xerosis, chronic dacryocystitis, and even blindness, thus requiring active treatment.

What medicine treats trachoma?

Medications used to treat trachoma include tetracycline eye ointment, rifampicin eye drops, sodium sulfacetamide eye drops, and erythromycin eye ointment. Tetracycline eye ointment inhibits the growth and reproduction of Chlamydia trachomatis and is suitable for use during the active phase of trachoma. The ointment should be applied inside the eyelid once nightly. Consistent use can reduce ocular inflammation and decrease follicular and papillary hyperplasia. It is important to complete the full course of treatment to prevent recurrence.

What consequences may result from applying a bandage too tightly for hemostasis?

Consequences of overly tight hemostatic bandaging mainly include impaired blood circulation, symptoms of nerve damage, local tissue necrosis, aggravated limb swelling, and restricted movement.
