What Are the Different Types of Eye Diseases?

The eyes are the windows to the soul and are crucial to human health. Eye diseases are also common in daily life. Some severe eye diseases, if not treated promptly, may even carry the risk of blindness. Therefore, it is necessary to seek timely treatment once eye diseases occur. There are various types of eye diseases, such as trachoma, cataracts, glaucoma, floaters, macular degeneration, and so on.

Trachoma is a chronic infectious conjunctival keratitis, mainly caused by insufficient secretion of aqueous humor in the eye, uneven distribution, and excessive evaporation of tears, leading to dry eyes and inflammation due to friction between tissues. If not taken seriously, it can be contagious and may even lead to blindness.

Cataracts are a very common eye disease. The main cause of cataracts is the pathology of the lens. When the lens accumulates a large amount of toxins and lacks timely supplementation of necessary nutrients, it becomes cloudy, resulting in cataracts. Cataracts can be divided into initial, immature, mature, and over-mature stages, with each stage being more severe than the previous one.

Glaucoma is another common eye disease with a high risk of blindness. The main cause of glaucoma is excessive toxins and blocked debris in the eye, leading to disrupted aqueous humor circulation and inability to drain in a timely manner. This results in elevated intraocular pressure, making glaucoma more prone to occur.

Many people may experience seeing small black spots or lines in their vision, which is known as "floaters". Floaters are mainly caused by vitreous body lesions in the eye. As the vitreous body liquefies with age and is eroded by toxins and debris, it can easily lead to floaters.

Macular degeneration is mainly caused by retinal lesions. It is an aging process that occurs with age and does not involve bleeding or exudation in the fundus. The progression of the disease is slow, and vision gradually decreases. The most common symptoms include blurred vision, difficulty distinguishing details without additional lighting, and difficulty recognizing faces at a distance. The harm of macular degeneration cannot be ignored.
