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.

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...
Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Summary
This summary is machine-generated.

Topical steroid use after hyperopic LASIK surgery caused severe glaucoma and vision loss in one eye. Early detection of elevated intraocular pressure is crucial after refractive surgery.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Hyperopic LASIK surgery can be complex, sometimes requiring re-treatment.
  • Topical steroid use is common post-LASIK for inflammation control.

Observation:

  • A 28-year-old female developed steroid-induced glaucoma after 2 years of topical steroid use for complicated hyperopic LASIK.
  • The patient experienced significant optic nerve damage and vision loss (1/15) in the treated eye.

Findings:

  • Steroid-induced elevated intraocular pressure (IOP) led to glaucomatous optic neuropathy.
  • An erroneously low IOP measurement may have delayed diagnosis.
  • Possible factors include fluid accumulation or altered biomechanics post-hyperopic LASIK.

Implications:

  • This case highlights the risk of severe complications from prolonged topical steroid use post-LASIK.
  • Emphasizes the critical need for diligent postoperative IOP monitoring in refractive surgery patients.
  • Underscores the potential for functional blindness due to delayed diagnosis of steroid-induced glaucoma.
