Eyes

Good vision depends on the lens, retina, optic nerve, and brain all successfully working together. Visual disorders such as short- and long-sightedness, which can usually be corrected with spectacles, are extremely common. Eye disorders range from mild conjunctivitis to serious disorders such as glaucoma (“green star”).

Conjunctivitis

Typical signs of conjunctivitis are eyelids that stick together and an itching and burning sensation in the eyes. It can be caused by viruses or bacteria, but can also have other causes.

Surfer’s eye (pterygium)

A pterygium (surfer’s eye) is a growth of tissue on the conjunctiva of the eye. It is often visible as a patch or area of cloudy white in the corner of the eye next to the nose.

Macular degeneration

Age-related macular degeneration (AMD) intensifies the natural deterioration of the eyesight as people age. More about origin, symptoms, and treatment of this eye disease.

Presbyopia

Most people in their mid-forties begin to experience presbyopia, i.e., a loss of near vision. Presbyopia cannot be reversed but treatment compensates effectively for the symptoms.

Styes and chalazia: what is eyelid inflammation and how is it treated? Learn more about the symptoms, causes, and treatment.

Glaucoma

Eye diseases like glaucoma can occur as we get older. The disease is also known as green star. Potential sight loss can be stopped if identified early.

Cataract (gray star)

A cataract gradually turns the lens of the eye cloudy. The person's sight then becomes increasingly blurred, as if looking through a veil or fog. In the long term, only an operation will help.

Small foreign bodies in eye

A small foreign body can quickly get into an eye. Sometimes the cornea of the eye is damaged in the process. A superficial injury usually heals within a short time.

Retinal detachment

Retinal detachment is an emergency that requires rapid treatment. Find more information here about symptoms, outlook, and treatment.

Dry eye

Dry eye often causes soreness and burning sensations, as well as redness and swollen eyelids. The symptoms usually respond well to treatment.

Color blindness

The term “color blindness” is used to describe various conditions that involve an inability to distinguish certain colors or any colors at all.

Lacrimal duct diseases

Lacrimal duct diseases may affect the lacrimal glands and the draining tear ducts. Read more about lacrimal duct obstruction and lacrimal gland inflammation here.

Keratoconus

With keratoconus, the cornea of the eye becomes increasingly distorted and vision deteriorates. Different treatment options are available, depending on the stage.

Short-sightedness

People with short-sightedness (also called near-sightedness or myopia) have blurred, unclear vision of objects in the distance. Short-sightedness can be corrected by wearing glasses or contact lenses.

Corneal ulcer

A corneal ulcer involves damage to parts of the cornea. It often heals after the causes have been treated – but scars may remain on the cornea.

Corneal irregularity (astigmatism)

With astigmatism, the image on the retina is blurred. Spectacles, contact lenses or an operation can correct this sight defect.

Lazy eye in children

Lazy eye is a common visual defect in children. One eye sends the brain an image that is more blurred than the other. This prevents children’s eyesight from developing properly.
