The examination of the fundus is a crucial diagnostic procedure. Using an ophthalmoscope, it is possible to look through the pupil at the back of the eye and examine the retina, the optic nerve, the blood vessels, and the choroid.…
In ophthalmology, the eye is divided into two sections: the anterior and posterior segments. The anterior segment includes the optical components of the eye: conjunctiva, cornea, iris, and lens. This sensitive area can be affected by inflammation, infections, mechanical injuries,…
During the preventive examination for glaucoma, intraocular pressure measurement (tonometry) is performed and the optic nerve head is assessed. The examination can determine whether intraocular pressure has increased and whether there is suspicion of glaucoma. How Does Elevated Intraocular Pressure…
A healthy optic nerve head is slightly indented inward. The optic nerve transmits our sensory impressions from the eye to the brain. Blood vessels run through its center to supply the retina. The optic nerve head, known as the optic…
When one sense fails, the other senses must take on its work additionally. The eyes play a special role in this. The human senses are the contact to the environment. The human brain assembles the fireworks of neurons from the…
Visual field testing is primarily used for the early detection of glaucoma. During a visual field examination (perimetry), the outer and inner boundaries of the visual field are assessed, as well as the sensitivity of visual function outside the point…
No. Presbyopia is caused by the lens’s natural aging process. It becomes increasingly rigid, leading to a loss of the ability to see clearly at close range. This process cannot be influenced by wearing glasses. One simply becomes accustomed to…
In children, it is extremely important to detect and correctly treat vision problems early. The brain learns to see during the first years of life. Problems that are not addressed before school entry can lead to significant visual impairments. If…
While it is not harmful for adults, it can be strenuous and tiring. Potential harm in children is discussed, but there is no definitive scientific evidence.
The causes are diverse and often multifactorial. Foreign bodies in the eye or minor corneal injuries, as well as inflammation and allergies, lead to increased tear production. On one hand, this helps flush out foreign bodies, and on the other,…
