Burning Eyes

  • Complications of eyelid burns Eyelid burns may damage lacrimal, conjuctival, and eyelid glands which can decrease tear production or their scarring may also inhibit lacrimal drainage system and blink reflex which increases the risk of corneal drying,[ijburns.com]

Facial Scar
  • As the risk for ectropion persists for months due to persistent eyelid shrinkage, a tarsorrhaphy would need to remain in place until facial scars mature. [23] c.[ijburns.com]

Prevention

  • It prevents the delayed penetrating damage caused by the alkali. Locally any antibiotic may be used to prevent infection.[ijo.in]
  • First Inflammatory Wave 12 to 24 hours after exposure Immune system response cannot be prevented Aggressive treatment with high-dose steroids Second Inflammatory Wave Typically begins at day 7 Associated with corneal repair and degradation Most intense[decisionmakerplus.net]
  • Doctors may also give cycloplegic eye drops (such as cyclopentolate or homatropine ) to prevent painful spasm of the muscles that constrict the pupil, as well as an antibiotic eye ointment to prevent infection. NOTE: This is the Consumer Version.[msdmanuals.com]
