Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

856
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: Treatment

978
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

1.1K
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...

Summary

Radiation therapy for head and neck cancers can cause eye complications. Higher radiation doses increase the risk of dry eye syndrome, corneal issues, and cataracts.

Area of Science:

  • Ophthalmology
  • Radiation Oncology
  • Oncology

Background:

  • Head and neck radiation therapy can lead to ocular complications.
  • Quantifying these risks is crucial for patient management.

Purpose of the Study:

  • To determine the incidence of eye complications in head and neck cancer patients receiving radiation.
  • To correlate these complications with specific cancer types and radiation doses.

Main Methods:

  • Retrospective analysis of 25 patients treated between 2011-2018.
  • Patients had orbital lymphoma, nasopharyngeal carcinoma, or cranial base meningioma.
  • Comprehensive ophthalmologic and orthoptic evaluations were performed.

Main Results:

  • Dry eye syndrome (DES) and corneal complications increased with radiation doses exceeding 40 Gy.
  • Cataract incidence rose with lens doses above 5 Gy.
  • Retinal nerve fiber layer (RNFL) thinning and visual field mean deviation (MD) worsened at doses over 50 Gy.

Conclusions:

  • Radiation dose is correlated with the development of ocular complications.
  • These findings highlight the dose-dependent nature of radiation-induced eye damage.
