Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.0K
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: Overview

560
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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Anatomy of the Eyeball01:20

Anatomy of the Eyeball

7.1K
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...

Area of Science:

  • Ophthalmology
  • Genetics
  • Neurology

Background:

  • Leber's hereditary optic atrophy (LHON) is a genetic optic neuropathy.
  • It primarily affects young males but can occur across all ages.
  • Mitochondrial genetic mutations causing electron transport chain complex I dysfunction are the main cause.

Purpose of the Study:

  • To highlight the characteristics of LHON.
  • To emphasize its differential diagnosis from optic neuritis.
  • To stress the importance of interdisciplinary collaboration.

Main Methods:

  • Clinical presentation analysis of LHON.
  • Review of diagnostic assessments including pupillary light reflex, fluorescein fundus angiography, and MRI.
  • Comparison with optic neuritis.

Main Results:

  • LHON causes acute to subacute, severe visual impairment, often progressing to both eyes.
  • Corrected visual acuity is frequently below 0.1.
  • Differential diagnosis from optic neuritis is critical.

Conclusions:

  • LHON must be considered in the differential diagnosis of optic neuritis.
  • Accurate diagnosis and treatment require collaboration between neurologists and ophthalmologists.
