The Far Nasal Part of the Visual Field - Part I
Summary
This study determined the far nasal visual field limits in healthy subjects. The nasal visual field extended up to 110 degrees when the nose was not obstructing the view.
Area of Science:
- Ophthalmology
- Visual Science
Background:
- The nasal visual field is crucial for overall visual perception.
- Understanding its limits is important for diagnosing visual field defects.
Purpose of the Study:
- To determine the far nasal visual field limits in healthy individuals.
- To establish normative data for the nasal visual field extent.
Main Methods:
- Visual field examination using a Medmont M700 instrument.
- Involved 15 healthy subjects (30 eyes) with normal ocular findings.
- Utilized flicker stimuli and a spatial accommodation program with head repositioning.
Main Results:
- The far nasal visual field limit reached 100° in 13.3% of eyes.
- Extended to 105° in 20% of eyes.
- Reached up to 110° in 66.7% of eyes.
Conclusions:
- The far nasal visual field limit typically extends to 100-110 degrees.
- This range was observed when nasal obstruction was minimized.

01:21Association Areas of the Cortex
5.4K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

01:27Cranial Bones: Lateral View
2.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:24Vision
53.5K
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.

01:20Anatomy 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...

01:24Nose and Nasal Cavity
2.6K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

01:03Olfactory Receptors: Location and Structure
9.3K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
