Vision01:24

Vision

61.2K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

10.6K
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,...

Teeth01:15

Teeth

2.1K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Tooth Anatomy

2.6K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

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...

Anatomy of the Eyeball01:20

Anatomy of the Eyeball

11.2K
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:

  • Oral surgery
  • Ophthalmology
  • Periodontology

Background:

  • Corneal diseases cause widespread blindness, with synthetic keratoprosthesis offering limited success due to foreign body reactions.
  • Autologous osteo-odonto keratoprosthesis (OOKP) utilizes oral structures to restore vision, especially in severe cases.
  • The success of OOKP relies heavily on the health of the periodontium for successful grafting.

Purpose of the Study:

  • To highlight the lesser-known role of the periodontium and oral structures in restoring vision.
  • To acknowledge the significance of periodontal health in the success of OOKP.

Main Methods:

  • Review of existing literature on osteo-odonto keratoprosthesis.
  • Analysis of the periodontal support required for successful OOKP grafting.

Main Results:

  • Osteo-odonto keratoprosthesis demonstrates a viable method for vision restoration in severe eye damage.
  • Periodontal health is a critical determinant for the long-term success and integration of OOKP.

Conclusions:

  • The periodontium's role extends beyond oral health, significantly impacting ophthalmological procedures.
  • Further research into periodontal contributions to vision restoration is warranted.
