Insights

Dry eye is common after pediatric strabismus surgery, affecting nearly half of patients initially. Children with lower preoperative tear breakup time (BUT) face a higher risk of developing post-surgery dry eye.

Area of Science:

  • Ophthalmology
  • Pediatric Surgery
  • Ocular Surface Disease

Background:

  • Pediatric strabismus surgery is a common procedure.
  • Post-surgical dry eye can impact patient recovery and visual outcomes.
  • Understanding the incidence and risk factors for dry eye is crucial.

Purpose of the Study:

  • To determine the incidence of dry eye following pediatric strabismus surgery.
  • To identify risk factors associated with post-operative dry eye.

Main Methods:

  • Prospective cohort study involving children aged 5-12 years undergoing strabismus surgery.
  • Ocular surface assessments performed pre-operatively and at 1, 4, and 8 weeks post-surgery.
  • Key outcome measures included dry eye incidence and tear breakup time (BUT).

Main Results:

  • The incidence of dry eye was 47.62% at 1 week, decreasing to 10.71% by 4 weeks and 0% by 8 weeks.
  • Lower preoperative tear breakup time (BUT) was significantly associated with a higher incidence of dry eye (OR 0.647, P≤0.01).
  • Tear film instability was identified as a more prevalent issue than deficient aqueous tear production.

Conclusions:

  • Dry eye is a frequent complication after pediatric strabismus surgery.
  • Preoperative tear film instability, indicated by low BUT, is a significant risk factor.
  • Early identification of children with low BUT can help predict and manage post-operative dry eye.

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
