Angle Closure Glaucoma: Treatment

1.6K
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: Overview

1.7K
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: Treatment

1.1K
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.

Papillary Dermis

5.8K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Area of Science:

  • Ophthalmology
  • Dermatology
  • Toxicology

Background:

  • Prickly pear plants (Opuntia spp.) possess fine, barbed spines called glochids.
  • Glochid exposure can lead to ocular and extra-ocular injuries, particularly in agricultural settings.

Purpose of the Study:

  • To investigate the clinical characteristics, presentation, and management of ocular and extra-ocular injuries caused by prickly pear glochids.

Main Methods:

  • A retrospective review of 21 patients (23 eyes) treated for ocular prickly pear spines between August and October 2011.
  • Data collected included patient demographics, exposure history, clinical findings, and treatment outcomes.
  • Glochid removal was performed under topical anesthesia using forceps at the slit lamp.

Main Results:

  • The majority of patients presented with eye irritation (95.2%) and pain (57.1%).
  • Common ocular findings included superior corneal epithelial erosions or ulcers (33.3%) and conjunctival involvement, predominantly in the upper subtarsal space (47.6%).
  • Extra-ocular glochid findings were noted in 38.1% of patients.

Conclusions:

  • Ocular injuries from prickly pear glochids are a significant concern during summer months and should be considered in patients presenting with eye pain.
  • Farmers and individuals working with prickly pear plants should utilize protective eyewear and gloves to mitigate the risk of injury.
