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...
Focusing of Light in the Eye01:16

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
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...

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Refractive Surgery Outcomes

Context:

  • Refractive surgery is increasingly popular.
  • Iatrogenic keratectasia is a severe complication.
  • Understanding risk factors is essential for patient safety.

Purpose:

  • To review current knowledge on iatrogenic keratectasia.
  • To identify key risk factors associated with its development.
  • To discuss diagnostic and therapeutic strategies.

Summary:

  • Iatrogenic keratectasia cases have increased since 1998.
  • Preoperative irregular topography is a primary risk factor.
  • Other risk factors include thin corneas, deep ablations, thin residual stromal beds, and young patient age.

Impact:

  • Despite improved preoperative assessments and stricter criteria, keratectasia still occurs.
  • Longer follow-up periods are recommended for early detection.
  • Prompt diagnosis facilitates effective therapeutic interventions.
