Glaucoma: Overview01:25

Glaucoma: Overview

702
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

527
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

628
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.3K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Summary

The risk of children diagnosed with glaucoma suspect status progressing to glaucoma is low. Higher risk factors include elevated intraocular pressure and periocular lesions.

Area of Science:

  • Ophthalmology
  • Pediatric eye care
  • Glaucoma research

Background:

  • Pediatric glaucoma suspect (GS) status requires careful monitoring due to potential progression.
  • Understanding risk factors and outcomes is crucial for timely intervention in children.

Purpose of the Study:

  • To characterize children with glaucoma suspect status.
  • To determine clinical outcomes for pediatric glaucoma suspects.
  • To identify risk factors for progression to glaucoma in children.

Main Methods:

  • Retrospective cohort study of children (<18 years) diagnosed with GS between 2013-2019.
  • Exclusion criteria included trauma, steroid-response, and existing glaucoma.
  • Outcomes assessed included glaucoma, ocular hypertension, and persistent GS status.

Main Results:

  • Of 887 children diagnosed with GS, 14 (3%) progressed to glaucoma.
  • Glaucoma diagnosis was associated with elevated intraocular pressure (IOP ≥24) and periocular lesions.
  • Most children either remained GS or had non-glaucomatous cupping.

Conclusions:

  • The risk of pediatric glaucoma suspects converting to glaucoma is low.
  • Elevated baseline IOP and periocular lesions are significant risk factors for glaucoma development.
  • Cup:disk ratio and family history were not predictive of glaucoma diagnosis in this cohort.
