Examine visual field

Examine visual field

Visual field determination is used primarily for early detection of glaucoma. During the visual field examination (perimetry), the examination of the outer and inner limits of the visual field as well as the sensitivity of the visual function outside the site of fixation is performed.

The visual field comprises that area of vision which can be grasped with unmoving eyes and head. Rough estimation of the visual field is performed with the simple parallel test, in which the patient's visual field is compared with that of the examiner. The exact visual field determination is done by computer perimetry.

Anatomy of the human eye

Human eye

The eye is one of our most important sensory organs for orienting ourselves in our environment. In its structure and functioning, the eye can be compared to a camera lens: Light rays ...

Outer eye shell

The outer shell is formed by the transparent cornea and the opaque white sclera. Both tissues give the eye its shape and strength. The conjunctiva covers the sclera in front ...

Conjunctiva (lat. Tunica conjunctiva) & Eyelid

The conjunctiva "connecting garment" (lat. Tunica conjunctiva) is a mucous membrane of the anterior segment of the eye and surrounds the cornea and the visible white part of the eye. With each blink, the conjunctiva distributes ...

Ciliary muscle (lat. Musculus ciliaris)

The ciliary muscle belongs to the inner eye muscles and is located in the ciliary body (lat. corpus ciliare) - also called the ray body. The ciliary body is a section of the middle eye skin and, besides the suspension ...

Posterior eye chamber (lat. Camera posterior bulbi)

The posterior chamber of the eye is smaller than the anterior chamber. It extends from the iris to the vitreous body - in it lies the lens. The aqueous humor - which covers both the posterior ...

Cornea (lat. Cornea)

Light enters the eye through the cornea, where it is then transmitted to the lens and pupil. The cornea is therefore also called the "window of the eye" and is a ...

Pupil (lat. pupilla): Eye hole of the eye

The pupil is the circular aperture in the center of the iris. Light enters the interior of the eye through the pupil. Its size is regulated by the surrounding iris, depending ...

Rainbow skin (lat. Iris)

The iris is the colorful part of the eye and is as individual as a fingerprint. The so-called iris, or "colorful aperture" of the eye, can be changed by an individual pigment distribution in ...

Middle eye shell

The middle shell consists of three sections with specific functions. The iris adjusts the incidence of light. The ciliary body produces aqueous humor and regulates the curvature of the lens for near or ...
