Is the pupil of corneal disease normal?

summary

Fungal keratitis is a kind of infectious keratopathy caused by pathogenic fungi with high blindness rate. Therefore, treatment has become a more concerned topic. The onset of fungal keratitis is slow and the course of disease is long. The course of disease can last for 2 to 3 months. Corneal ulcer often occurs within a few days of onset. So let's share the following corneal disease pupil normal?.

Is the pupil of corneal disease normal?

First, the etiology of fungal keratitis. In general, fungi do not invade the normal cornea, but when there are ocular trauma, long-term local use of antibiotics, keratitis and dry eye, non pathogenic fungi may become pathogenic bacteria, causing secondary fungal infection of the cornea. The common pathogenic bacteria were Aspergillus, Fusarium, Candida albicans, cephalosporins and Streptomyces. The morphology of corneal ulcer is different due to different pathogenic bacteria. Fungal keratitis is not uncommon. In summer and autumn, the incidence rate is high in busy seasons. In terms of age and occupation, it is more common in young adults, the elderly and farmers.

Second: fungal keratitis has a slow onset, subacute course, severe irritation symptoms and visual impairment. The corneal infiltrating foci were white or gray, dense, less glossy, toothpaste like or mossy appearance. There were shallow grooves formed by collagen dissolution around the ulcer, or immune rings formed by antigen antibody reaction. Sometimes pseudopodia or satellite like infiltrating foci can be seen near the corneal lesions, and plaque like fibrous purulent deposits can be found after the lesions. Anterior chamber empyema, gray white, viscous or mushy. Fungal endophthalmitis is easy to occur when it enters the anterior chamber or corneal perforation.

Third: corneal foreign body refers to some dust, small insects, metal debris and sawdust into the cornea caused by an ophthalmic emergency. When the eyes enter the foreign body, first of all, there will be foreign body sensation, photophobia, tears and other discomfort symptoms. At this time, do not rub the eyes, not careless, to the hospital in time. With slit lamp, doctors can see that the bulbar conjunctiva of the eyes is red, that is, hyperemia or ciliary hyperemia, and there will be foreign bodies on the corneal surface. If it is iron filings, rust rings can be left for a long time, which is difficult to clean up; If it has been infected, gray infiltrating ring can be seen around the foreign body, so it is necessary to see a doctor as soon as possible. The foreign body attached to the corneal surface can be washed or removed with a wet cotton swab. The shallow foreign body can be removed with a fine injection needle under topical anesthesia. The foreign body at the deeper point or that has entered the front needs to be removed in the operating room.

matters needing attention

Therefore, corneal foreign body is not as simple as imagined, which can not be solved by random rubbing, blowing or washing. We should seek medical treatment as soon as possible and eliminate foreign body as soon as possible to avoid more serious disease development.
