Glaucoma: Overview01:25

Glaucoma: Overview

1.6K
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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.5K
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

10.4K
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

Behçet disease can rarely cause acute optic neuropathy, leading to sudden vision loss. Prompt corticosteroid treatment can resolve ocular findings effectively.

Area of Science:

  • Ophthalmology
  • Rheumatology
  • Neuro-ophthalmology

Background:

  • Behçet disease is a rare multisystem inflammatory disorder.
  • Ocular involvement is common but acute optic neuropathy is an infrequent manifestation.

Purpose of the Study:

  • To present a case of Behçet disease with acute optic neuropathy.
  • To highlight the diagnostic and therapeutic considerations for this rare presentation.

Main Methods:

  • A 47-year-old male patient presented with sudden unilateral visual loss.
  • Comprehensive ophthalmologic and systemic examinations were conducted.
  • Treatment with high-dose corticosteroids was initiated.

Main Results:

  • The patient experienced significant visual impairment in the left eye.

  • Funduscopic examination revealed optic disc swelling and a relative afferent pupillary defect.
  • Ocular symptoms improved within two weeks of corticosteroid therapy.

    • Conclusions:

    • Acute optic neuropathy is an uncommon but possible presentation of Behçet disease.
    • Early diagnosis and aggressive corticosteroid treatment are crucial for visual recovery.
