Anatomy of the Eyeball01:20

Anatomy of the Eyeball

9.3K
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...

Glaucoma: Overview

1.2K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

8.6K
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

Optic disc drusen can cause slight visual field decline with age. Marked visual field defects and reduced visual acuity are rare in patients with optic disc drusen.

Area of Science:

  • Ophthalmology
  • Neuro-ophthalmology

Background:

  • Optic disc drusen are often assumed to cause slowly progressive visual field defects.
  • Previous beliefs suggested defects mainly occur in adolescence and stabilize later in life.

Purpose of the Study:

  • To validate assumptions regarding the progression of visual field defects in optic disc drusen.
  • To assess the long-term impact of optic disc drusen on visual function.

Main Methods:

  • Retrospective analysis of 255 patients diagnosed with optic disc drusen.
  • Verification of diagnosis and quantification of visual fields and visual acuity from patient records.

Main Results:

  • 104 cases had sufficient data for analysis; significant visual field defects were uncommon.

  • Older age correlated with a higher incidence of visual field defects.
  • Mild decline in visual acuity was observed in patients over 60 years.

    • Conclusions:

    • A continuous, slight decline in visual field with age is likely in optic disc drusen patients.
    • Severe visual field defects and significant visual acuity loss are rare.
    • Findings suggest optic disc drusen have a limited impact on long-term visual function for most patients.
