Anatomy of the Eyeball01:20

Anatomy of the Eyeball

11.4K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

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...

Photoreceptors and Visual Pathways

10.9K
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,...

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...

Angle Closure Glaucoma: Treatment01:28

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...

Summary
This summary is machine-generated.

Acute zonal occult outer retinopathy (AZOOR) can cause sudden vision loss with normal eye exams. An electroretinogram (ERG) is crucial for diagnosing AZOOR in patients with unexplained visual field loss.

Area of Science:

  • Ophthalmology
  • Neuro-ophthalmology

Background:

  • Retinal photoreceptor dysfunction is an infrequent cause of acute visual loss.
  • Acute zonal occult outer retinopathy (AZOOR) is a condition characterized by cone and rod dysfunction.

Observation:

  • A young female presented with acute, unilateral visual field loss and an afferent pupillary defect.
  • Initial examinations, including visual acuity, funduscopy, and fluorescein angiography, were normal.

Findings:

  • A pattern visual evoked potential was normal.
  • An electroretinogram (ERG) revealed unilateral peripheral photoreceptor dysfunction, confirming AZOOR.

Implications:

  • Ophthalmologists should consider AZOOR in cases of unexplained visual field loss.
  • An ERG is recommended for diagnosing AZOOR, even with normal visual acuity and retinal examinations.
