Insights

Pseudophakic children experienced greater axial length increase compared to non-operated eyes. This axial elongation was more pronounced in younger children (under 5) undergoing cataract surgery.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Biomedical Engineering

Background:

  • Pseudophakic children often exhibit significant myopic shifts.
  • Accelerated axial length growth is a potential contributor to this myopic shift.
  • Understanding axial length changes is crucial for managing visual development in these children.

Purpose of the Study:

  • To evaluate and compare the postoperative change in axial length (DeltaAL) in pseudophakic eyes.
  • To compare axial length changes after traumatic versus congenital cataract extraction in children.
  • To investigate the influence of age at operation on axial elongation.

Main Methods:

  • Retrospective study of 20 children under 10 years old who underwent cataract surgery.
  • Axial length (AL) measured perioperatively and at least 1 year postoperatively.
  • Comparison of DeltaAL between operated and fellow non-operated eyes, stratified by age and cataract type.

Main Results:

  • Operated eyes showed a trend towards greater axial elongation than fellow eyes (p=0.06 for traumatic, p=0.055 for unilateral congenital cataracts).
  • Axial elongation was significantly greater in children operated on before age 5 (p=0.025).
  • The rate of DeltaAL was similar between traumatic and unilateral congenital cataract groups.

Conclusions:

  • Pseudophakic eyes in children tend to exhibit greater axial lengthening compared to their non-operated fellow eyes.
  • No significant difference in the tendency for increased axial lengthening was observed between eyes operated for traumatic versus congenital cataracts.
  • Age at the time of surgery is a significant factor influencing axial elongation in pseudophakic children.

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...
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...
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...
