Have you ever wondered what it would look like if someone had asymmetry in their eyes, specifically the front part, which includes the pupil and iris? This phenomenon can best be described as Axenfeld-Rieger Syndrome, an eye disorder that can have additional effects on the rest of the body. Axenfeld-Rieger Syndrome, additionally, is a rare condition that affects 1 in every 200,000 people.
Quadrantanopia and hemianopia are two types of visual impairment that affect individuals differently. Both of these conditions are caused by damage to the brain, specifically the occipital lobe, which is responsible for processing visual information.
Trachoma is a bacterial infection that affects the eyes and is caused by the bacterium Chlamydia trachomatis. It is a major public health problem in many parts of the world, particularly in areas with poor sanitation and limited access to healthcare.
There are many skin conditions that can affect the skin around the eyes. The skin around the eyes is some of the most fragile and delicate on the body, so it can be very easy for it to develop issues. It is one of the first places on the body to show fatigue and signs of aging.
Leber Congenital Amaurosis (LCA) is an inherited retinal ciliopathy that affects the eyes, causing severe vision loss at birth. Children with LCA may experience complete blindness, repetitive, uncontrolled eye movements, and slow or absent pupillary responses. Additionally, individuals with LCA are subjected to severely impaired acuity of vision, eye discomfort in bright light, and extreme farsightedness. These impairments function together in the resulting overall loss of vision.

As humans, we have access to advanced technology and medical procedures to correct our eyesight, if needed. Other species, such as tarsiers, mantis shrimp, and underwater creatures, do not have these same resources to repair their vision. However, many of these species have much better baseline vision than humans do.
Have you ever wondered how we are able to learn so much about the eye and the diseases affecting it? Through research and clinical studies and trials! A clinical study is a type of research that tests how well new medical approaches work in people. Anyone who is eligible for specific clinical studies can participate to help contribute to research to further medical advancements. Participating in these studies may also offer compensation for people’s time as an incentive to recruit more participants.
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.
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.
