Summary
Strabismus patients with abnormal binocular vision show reduced retinal thickness in dominant eyes. This suggests potential neural degeneration affecting the visual pathway and ganglion cells.
Area of Science:
- Ophthalmology
- Neuroscience
- Retinal Imaging
Background:
- Strabismus, or eye misalignment, often impacts binocular vision development.
- Understanding retinal changes in strabismus is crucial for diagnosing and managing visual impairments.
Purpose of the Study:
- To investigate retinal morphological changes in strabismus patients with abnormal binocular vision.
- To compare quadrantal macular retinal thickness differences between strabismus patients and controls.
Main Methods:
- Optical coherence tomography (OCT) was used to measure macular retinal thickness.
- Total macular retinal (TMR) and ganglion cell complex (GCC) thicknesses were assessed in 3- and 6-mm regions.
- Quadrant ratios were calculated to analyze thickness variations.
Main Results:
- Dominant eyes of strabismus patients had significantly lower superior/inferior (S/I) ratios for TMR and GCC thickness in the 3-mm region compared to controls.
- The superior temporal/inferior temporal (ST/IT) ratio of GCC thickness was also significantly lower in the dominant eyes of strabismus patients.
Conclusions:
- Dominant eyes in strabismus patients with abnormal binocular vision exhibit thinner superior temporal GCC in the 3-mm region.
- These findings suggest efferent neural degeneration may affect retinal ganglion cells in strabismus.
- This degeneration likely originates in the visual pathway, adapting to visual experiences.

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.

17.4K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Overhead power transmission lines rely on cables to carry electricity across large distances. To ensure the stability and functionality of these lines, it is crucial to understand the shape and tension experienced by the cables under the influence of their weight.
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
