Anatomy and function of the eye

Sight is one of our most important senses, and over 80 percent of all the impressions we take in during a day come from the eyes. In order to understand how different eye diseases can affect vision, it is important to have a basic understanding of the anatomy of the eye and its functions.

The eye is a complex organ that works by receiving light and converting it into signals that the brain can interpret as images. The eye consists of several important parts, including the cornea, iris, lens, retina, and vitreous. Each part has a specific role in the vision process, and disturbances in any of these parts can lead to vision problems.

That's how vision works

To create a visual impression, light must first be admitted through the pupil. The rays of light are then refracted in the cornea and lens with the goal of creating a sharp and focused image of the macula of the retina. From there, the information is sent on as signals to the brain via the optic nerve. The brain then interprets the information to create an image.

List of common eye diseases and problems

There are many different types of eye diseases and conditions, but some are more common than others. Here are some examples:

• Diabetic retinopathy: Affects people with diabetes and leads to damage to the small blood vessels of the retina. Without treatment, this condition can cause serious vision problems, in the worst case, blindness.
• Vitreous detachment: Occurs when the vitreous, the jelly-like substance inside the eye, pulls away from the retina. May cause visible spots or flashes in the field of vision.
• Cataracts: Characterized by clouding of the eye's lens, resulting in impaired vision. Is common in the elderly and can be treated with surgery.
• Glaucoma: A group of diseases that cause damage to the optic nerve, often due to increased pressure inside the eye. Without early treatment, glaucoma can lead to permanent vision loss.
• Retinal detachment: A serious condition in which the retina detaches from its supporting tissue, which can lead to sudden vision loss if not treated quickly.
• Iris – Iritis: An inflammation of the iris of the eye that can cause pain, light sensitivity and vision loss.
• Watery eyes: Common in babies and people over 60. Due to increased tear flow or blocked tear ducts.
• Red eyes: Can be due to a number of factors, for example eye inflammation, allergies, for example to pollen, or fatigue. Red eyes can sometimes be a sign of a more serious illness.
• Sjögren's syndrome: An autoimmune disease that causes dry eyes and mouth. This can lead to the eyes feeling gritty, stinging and irritated.
• Dry eyes: Caused by insufficient tear fluid or poor tear quality, leading to irritation, redness and sometimes impaired vision.
• Vagel: A lump on the eyelid caused by an infected sebaceous gland. Usually harmless and often goes away on its own.
• Age-related changes in the macula: A disease that affects the macula, the part of the retina that allows us to see clearly. Often leads to permanent visual impairment in the elderly. Available in two forms: dry and wet.
• Eye inflammation - Conjunctivitis: Inflammation or infection of the conjunctiva, often caused by viruses, bacteria or allergies. Symptoms include redness, itching and increased tear flow.
• Eyelid inflammation - Blepharitis: Inflammation in the edges of the eyelid. Can be caused by bacteria, blocked sebaceous glands, allergy or skin diseases.

Symptoms and diagnosis of eye diseases and eye problems

The symptoms of eye diseases can vary depending on which part of the eye is affected. Common symptoms are, for example, blurred vision, double vision, pain in the eye, increased sensitivity to light and sudden loss of vision. If you experience any of these symptoms, it is important to contact your healthcare provider immediately. With early diagnosis and treatment, many of the most serious eye diseases can be slowed down.

Treatment and preventive measures

In order to determine which treatment is appropriate, a doctor first needs to assess what is causing the discomfort. Mild complaints usually do not need to be treated at all, they heal on their own. You can ease the discomfort and speed up healing by gently washing the eye with lukewarm water a few times a day. Many complaints can also be alleviated with non-prescription eye drops that can be bought at the pharmacy. Avoid using make-up and contact lenses while you have discomfort.

More severe eye diseases may require different types of treatment. For example, you can receive treatment with prescription drugs, laser treatment or surgery.

When should I seek care?

When it comes to eye diseases and eye problems, it is important not to wait too long to seek care. You should contact an ophthalmologist or seek care at an eye clinic if you experience symptoms such as blurred vision, double vision, persistent pain in the eye, extreme sensitivity to light or sudden vision loss. Even with less severe but persistent symptoms, such as red eyes, watery eyes or a feeling of rubbing in the eye, you should seek medical attention, especially if the symptoms do not improve within a few days or recur regularly.

It is also important to seek urgent care if you have been exposed to a chemical in the eye or if you have injured the eye, for example through a blow or a cut. Children who complain of eye problems should also be examined by a doctor to avoid complications that could affect vision development.

Remember that early detection and treatment is absolutely critical to prevent long-term damage to the eye or vision loss. Regular eye exams are also recommended as a preventative measure, especially if you have a risk factor or heredity for eye disease.
