Definition
The inner (medial) as well as outer (lateral) eye angle forms the transition between the upper and lower eyelid. A skin rash can occur at both corners of the eye, which may be limited to the respective corner of the eye or may spread to other parts of the body. A definition seems to be difficult, because it is not a specific clinical picture, but there are different causes and diseases that can lead to a skin rash at the corner of the eye.
Causes
The causes of a rash at the corner of the eye can be very diverse. The common causes will be discussed in a short overview. Allergies can often be the cause of a rash, also at the corner of the eye.
A distinction is made between allergic rashes as part of general allergic reactions, such as a pollen allergy, and allergic contact eczema, which is caused by skin contact with an allergen, for example a fragrance. Indications of an allergic reaction or allergic contact eczema are itching, redness, swelling and small, raised skin symptoms known as hives. Blepharitis is an inflammation of the eyelid margin, which can have various causes.
Typical are thickened, red eyelids, which can have crusts and scaly deposits. Itching is also typical. Furthermore, it can lead to a loss of eyelashes and an accompanying inflammation of the conjunctiva with a foreign body sensation in the eye.
Herpes zoster is colloquially known as shingles. If the eye or the skin region around the eye is affected, it is called ophtalmicus zoster. It shows a typical blister-like reddened rash in the corner of the eye, which is accompanied by severe pain, burning sensations and general complaints such as fever.
Dell’s warts are small, flesh-colored, wart-like skin lesions that occur primarily on the eyelids and in the corner of the eye. Children and adolescents are particularly frequently affected. Dell’s warts usually do not cause any symptoms.
If the lacrimal sac is inflamed, there is redness and swelling around the inner corner of the eye. Pressure on the corner of the eye can cause pus or purulent secretion to be emptied. Pain is also typical for an inflammation of the lachrymal sac.
In contrast, an acute inflammation of the lacrimal gland is characterized by redness and swelling in the area of the upper eyelid and the outer corner of the eye. The eye takes on a typical paragraph shape. This type of inflammation is usually accompanied by severe pain.
