Purpose Of Review:
To review current practices for trachoma treatment with a focus on recent studies, particularly those discussing trachoma trichiasis surgery.
Recent Findings:
Azithromycin eye drops twice daily for 3 days may be as efficient as oral azithromycin in treating active trachoma. Facial cleanliness and environmental improvement programming should employ a variety of behavior change techniques to give sustained improvements. Posterior lamellar tarsal rotation carries a lower risk for trichiasis recurrence and is more effective in severe trachoma trichiasis than bilamellar tarsal rotation. Tarsoconjunctival incision can play a pivotal role in trichiaisis recurrence. Tarsus-sparing procedures continue to be refined with good success rates. Concurrent correction of lid abnormalities that commonly occur with trachoma trichiasis may maximize the result of surgery.
Summary:
Better understanding of the pathophysiology of trachoma and postoperative trichiasis recurrence is critical for effective trachoma control. Progressive tarsoconjunctival scarring in trachoma and high recurrence rates following tarsal rotation procedures raise the importance of adopting a procedure that spares tarsus/conjunctiva.

Drug clearance depends on the rate of drug elimination and its plasma concentration. Another important parameter is a drug's half-life, which is the time required for its concentration to decrease by half. In most cases, drug clearance follows first-order...

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
