The superficial punctate keratitis, corneal inflammation of various causes, is characterized by scattered, fine dot-shaped or Hornhautepithelverluste -schädigungen. The symptoms are redness, epiphora, photophobia, and a slight deterioration of visual acuity. The diagnosis is made by slit-lamp examination. Treatment depends on the cause.
The superficial punctate keratitis is a nonspecific finding. Possible causes are:
The superficial punctate keratitis, corneal inflammation of various causes, is characterized by scattered, fine dot-shaped or Hornhautepithelverluste -schädigungen. The symptoms are redness, epiphora, photophobia, and a slight deterioration of visual acuity. The diagnosis is made by slit-lamp examination. Treatment depends on the cause. The superficial punctate keratitis is a nonspecific finding. Possible causes are: Viral conjunctivitis (usually adenovirus) blepharitis keratoconjunctivitis sicca trachoma burns UV light exposure (eg, welding equipment, sunlamps, snow reflection.) Excessive wear contact lenses Systemic medications (such as adenine.) Topical medications or toxicity of preservatives Peripheral facial paralysis (including Bell’s palsy) symptoms are photophobia, foreign body sensation, epiphora, redness and a slight reduction of visual acuity. In the corneal examination with slit lamp or ophthalmoscope is a characteristic, blurred appearance with multiple point-like spots that can be stained with fluorescein shows. In a viral conjunctivitis, a preauricular adenopathy is common and it can be a chemosis occur. The Begleitkeratitis at a Adenoviruskonjunktivitis forms spontaneously within about 3 weeks. Blepharitis (blepharitis), keratoconjunctivitis sicca (keratoconjunctivitis sicca) and trachoma (trachoma) require a specific therapy. Keratitis caused by prolonged use of contact lenses with a contact lens and leave an antibiotic ointment treated (eg. As ofloxacin, ciprofloxacin or levofloxacin, 4 times a day), but without eye bandage, as may arise from the serious infections. (Editor’s note: According to Red List, there are ciprofloxacin and levofloxacin in Germany is not as eye ointment Ofloxacin is common [Floxal as preparation].). Contact lens wearers with a superficial punctate keratitis superficial should be examined the next day. The trigger topical medications suspected (active ingredient or preservative) should be discontinued. UV keratitis UVB light (wavelength <300 nm) can burn the cornea and lead to keratitis or keratoconjunctivitis. Arc welding is a common cause, and even a brief glance unprotected may result when welding in a combustion. Other causes include high-voltage spark, sunlamps or at high altitude with snow reflected sunlight. For the UV radiation increases per 305 meters above sea level by 4-6% in, and snow reflects 85% of the UVB. The symptoms become usually only 8-12 h after exposure noticeable and keep 24 to 48 h at. Patients have watery, sore, red eyes, swollen eyelids, photophobia, headache, a foreign body sensation and a reduction of visual acuity. A permanent loss of vision is very rare. Diagnosis is based on history, the finding of a superficial punctate keratitis and the absence of a foreign body or infection. The treatment consists of antibiotic ointment (eg. As bacitracin or gentamicin 0.3% ointment every 8 h) and, occasionally, a short-acting cycloplegic drug (z. B. 1% cyclopentolate -Tropfen every 4 h). (Editor's note: Bacitracin is not available in Germany as an eye ointment.) Severe pain can have a systemic analgesics required. The corneal surface regenerates spontaneously within 24-48 hours. The eye should be checked after 24 hours. Preventive effect sunglasses or welding helmets, block the UV light.
