Retinoblastoma is a rare type of eye cancer affecting the retina of the eye. Unfortunately, this is a common form of cancer found in very young children, generally under 5 affecting one or both eyes. It is rarely seen in adults.
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.
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:

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.
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.
There are many different cells involved in the pathway that communicates the light detected by photosensors in the retina to the rest of the brain. One important group of cells sense light, but do not help us see: they are involved in other functions such as maintaining/resetting the circadian rhythm.
Behcet’s Disease (BD), or Silk Road Disease, is s systemic vascular disease that affects many different organ systems in the body. It generally causes an inflammation of blood vessels in the body, which can lead to various symptoms. It is commonly seen as a triad of oral aphthous ulcers, genital ulcers, and ocular disease. The overall cause of this disease is unknown, but some speculate that it is an autoimmune disorder where the body’s immune system attacks itself.
