BACKGROUND We report the case of an 81-year-old woman with a history of radial keratotomy 9 years prior who developed endophthalmitis without preceding keratitis 4 days after uneventful photorefractive keratectomy surgery. This case report utilized clinical examination and microbacterial laboratory findings. FINDINGS Diagnosis of bacterial endophthalmitis was made via clinical examination and...

purpose : to report an atypical case of acanthamoeba keratitis. patients & methods : a 19-year-old girl presented with a history of recurrent herpetic keratitis and a history of short-time contact lens wear. laboratory work-up for herpetic, bacterial, and acanthamoeba sources were negative and the patient failied to follow up. on later presentation she had corneal necrotizing stromal ulcer need...

PURPOSE To evaluate a bacterial dot hybridization (BDH) assay for the diagnosis of bacterial keratitis (BK). METHODS Sixty-one qualified corneal scrapings from 61 patients with suspected microbial keratitis were collected consecutively and prospectively. Among the 61 patients, 16 cases were BK and 45 cases were non-BK, including fungal keratitis, viral keratitis, parasitic keratitis, and non-...

Bacterial keratitis is a serious ocular infectious disease that can threaten vision. The disease generally progresses rapidly and can lead to corneal scar, stromal abscess formation, perforation, and dissemination to adjacent tissues if not treated properly. Recent studies showed that corneal collagen crosslinking (CCC) using ultraviolet-A/riboflavin is effective in the treatment of bacterial k...

PURPOSE To report an unusual case of multifocal bacterial keratitis that despite success-ful treatment caused chronic ocular hypertension. METHODS A 67-year-old woman with unilateral multifocal keratitis and no previous ocular pathology was admitted to our hospital. Corneal scrapings and conjunctival samples were obtained for culture and the patient received intensive therapy with fortified v...

The use of contact lenses (CLs) has been widely associated with corneal alterations that range in symptomatology and severity. Lesions may vary from small peripheral sterile infiltrates to infectious central ulcers with sight-threatening potential. Contact lens wear has been described as the most important predisposing factor to microbial keratitis worldwide. Infections are more frequent in sof...

BACTERIAL KERATITIS Simple, uninfected cases of corneal ulceration can be treated with prophylactic antibiotics, mydriatics and systemic antiinflammatory agents. However, aggressive medical therapy is indicated in all cases of confirmed or suspected bacterial keratitis. This includes topical and systemic antimicrobial drugs, mydriatics and antiproteases, and sysemic non-steroidal antiinflammato...

Microbial keratitis is a major cause of corneal opacity and loss of vision worldwide. Ulcerative microbial keratitis remains a leading cause of blindness worldwide. The most common causative organisms are bacteria, although fungi and protists can also cause keratitis. Bacterial keratitis is potentially more devastating ocular infection. The most common bacteria associated with corneal ulcer are...
