PURPOSE: The authors report a case of Loxosceles reclusa infestation on the eyelid. METHODS: The specimen collected by swabbing the lesions with gauze was tested by using a venom-specific enzyme-linked immunosorbent assay. Loxosceles venom was detected in specimen. The patient was managed with conservative therapy that included saline compresses and ocular lubrication. RESULTS: The case presented with severe edema and necrosis on the left upper eyelid. On laboratory examination, a significant left shift of white blood cell count was detected. Although residual scar of the eyelid and punctate epitheliopathy on the inferior of cornea was detected, vision was not impaired. CONCLUSIONS: Supportive therapy may be reasonable treatment for Loxosceles reclusa infestation on the eyelids. The presence of venom proteins detected with an enzyme-linked immunosorbent assay technique is beneficial for supporting the diagnosis of Loxosceles envenomatio.

PURPOSE: A rare case of unilateral vernal keratoconjunctivitis is presented. METHODS: A 5-year-old boy had itching, foreign body sensation, redness, and ptosis in his left eye. Impression cytology specimens were taken from both upper eyelid tarsal conjunctiva. RESULTS: On slit-lamp biomicroscopy, unilateral cobblestone papillae and a shield ulcer were found in the left eye. On impression cytology examination, there was a significant increase in inflammation, presence of a honeycomb pattern, plasma cells, and mucus strands in the upper tarsal conjunctiva of the specimens. CONCLUSIONS: Giant papillary conjunctivitis must be considered in differential diagnosis of unilateral vernal conjunctivitis. Impression cytology method may be combined with the clinical findings in vernal keratoconjunctivitis diagnosis.

OBJECTIVES: This study analysed 420 patients with penetrating eye injuries who presented for treatment at the Eye Clinic of Dicle University Hospital in Turkey. The aim of the study was to identify preventable risk factors. METHODS: A retrospective evaluation of patients who presented between January 1995 and December 2000 was undertaken. Cases were examined with regard to age, sex, profession, which eye was traumatized, reason for the trauma, nature of the trauma, time between injury and operation, and accompanying pathologies. RESULTS: This study found that most penetrating eye injuries occurred in children aged 0-15 years, and these were mainly caused by accidents during play. For patients aged 16-60 years, penetrating eye injuries were mainly caused by work-related accidents. CONCLUSION: Most penetrating eye injuries were caused by preventable accidents. Many accidents and their resulting injuries could have been prevented by education, greater intensive care and workplace safety.
