Trauma foreign body causing

Although cataract surgery is a potential precursor to bullous keratopathy, there are many other causes. Fuchs endothelial dystrophy, infection, trauma, retained foreign body, posterior polymorphous dystrophy, chronic uveitis, chronically elevated intraocular pressure (lOP), and vitreous touch are all known causes of bullous keratopathy. Other less common causes of bullous keratopathy include corneal thermal injury secondary to carbon dioxide laser skin resurfacing, air bag trauma, the use of topical dorzolamide hydrochloride in glaucoma patients with endothelial compromise, and use of mitomycin C during trabeculectomy surgery. [Pg.493]

Approximately 42% to 64% of RCEs occur after superficial trauma to the cornea. Fingernail injuries are reported to be the most common cause of traumatic RCE. Other causes of traumatic RCE include injuries from paper, cardboard, vegetative material, contact lenses, foreign body removal, and trauma to the epithelium during LASIK. [Pg.504]

Table 8. Repeated microtrauma associated with onycholysis caused by foreign bodies. This may be associated with an acute trauma (metal) or repeated microtrauma (hairdressers, for example). Occupational onycholysis is most frequently due to chemical irritants or sensitizers. In addition, there are infective causes, which tend to be limited to medical personnel and occupations which entail prolonged soaking of the hands Candida and Pseudomonas)... Table 8.

Occasionally, an abnormally intense anterior segment inflammatory reaction occurs within the first 5 days after cataract extraction and can be characterized according to etiology as endophthalmitis, toxic iritis, or aseptic iritis. Endophthalmitis is discussed later in the chapter. Toxic iritis is usually produced by implanned intraocular introduction of drugs or chemicals acute aseptic hitis is caused by surgical trauma to the iris or ciliary body or (occasionally) by particulate foreign material inadvertently introduced at the time of surgery. [Pg.602]
