retina

 

[ หˆrษ›tษชnษ™ ]

Noun
Context #1 | Noun

anatomy

The retina is a thin layer of tissue located at the back of the eye that is essential for vision. It converts light that enters the eye into neural signals, which are then sent to the brain for interpretation. Damage to the retina can lead to vision impairment or blindness.

Synonyms

retinal membrane, visual membrane

Examples of usage

  • The retina detects light and color.
  • She underwent surgery to repair her detached retina.
  • Photoreceptors in the retina respond to light stimuli.
Context #2 | Noun

biology

In a broader biological context, the retina may refer to any similar tissue in other organisms that serves the function of light detection. While the structure and complexity may vary, the fundamental role of converting light into signals remains constant.

Synonyms

light-sensitive layer

Examples of usage

  • Many animals have a different type of retina adapted for their environment.
  • The study of the retina extends to various species in biology.
  • Researchers analyze the retina to understand evolutionary adaptations.

Etymology

The term 'retina' originates from the Latin word 'retina', which means 'net', as the structure of the retina resembles a net in its arrangement of cells. The usage of 'retina' in reference to the eye dates back to the 14th century, when it became an integral part of ophthalmology. Over time, the word has been adopted into various scientific contexts, particularly in biology and medicine, due to advancements in our understanding of vision and the role of the retina in the visual system. The study of the retina has expanded significantly with technological advancements in imaging and treatment, particularly related to retinal diseases and conditions affecting sight. Today, the retina is a critical focus of research aimed at improving eye health and combating visual impairments.
