Eye Movements

Submitted by palmergrabner on Mon, 03/27/2023 - 17:36

There are a variety of muscles that surround the eye: the lateral, medial, superior and inferior rectus muscles and the superior and inferior oblique muscles of the eye. These muscles work together to move the eye in specific ways which allow us to follow stimuli and interact with the world around us.

Vitreomacular Traction (VMT)

Submitted by maanavm on Fri, 03/24/2023 - 16:57

The middle of the eye contains a substance called vitreous, a gel-like substance that is  firmly attached to the retina and macula by millions of microscopic fibers. The vitreous shrinks away from the eye as it ages or if a disease occurs and over time, begins to separate altogether. This leads to a condition called posterior vitreous detachment (PVD), a normal part of aging happening at age 70.

As a condition that affects the facial skin, rosacea causes inflammation, burning, redness, and itchiness. This condition can be the result of an overactive immune system, genetics, or environmental factors. Unfortunately, this condition can act on the eyes as well, due to their vital role as a central part of the facial area.

Cosmetic products linked to mercury poisoning, which may facilitate blindness

Submitted by ryanthien on Sun, 02/26/2023 - 23:57

Last month, a CNN article reported that a Minnesota woman lost part of her vision, presumably as a result of using cosmetic products which contained higher amounts of mercury than expected. Scientists have long understood that higher exposure to the toxic chemical can facilitate mercury poisoning, but they were unaware of its potential implications on vision and optical health as related components of the poisoning.

Groupings of Eye Allergies

About one-fifth of the American population has an eye allergy. Despite this, many Americans do not realize that there are several different groupings of eye allergies that affect the correct treatment and precautions needed to follow for their allergies! The groupings are as follows:


Group 1: Seasonal and perennial allergic conjunctivitis

Horner Syndrome

After having a stroke or spinal cord injury, it is vital to ensure that the nervous system is still functioning properly. Signs that the nervous system has been impacted include delayed movements, difficulty with speech, and paralysis of certain muscles. Horner Syndrome, a condition that affects the neural pathways of the eye and face, is often caused by damage to the nervous system.

Bioprinting emerges in retinal applications at the NIH

Submitted by ryanthien on Sat, 02/04/2023 - 00:04

3D-printed applications in biology and medicine have risen dramatically in recent years, thanks in part to the preceding rapid advancements in 3D printing technology. In fact, in December 2022, researchers transplanted a 3D-printed ear constructed from stem cells into a woman who has microtia, a condition where a person’s ear may be partially or entirely missing.
