Although uncommon, allergy to peribulbar hyaluronidase injected during cataract surgery should be considered in the differential diagnosis of patients who present with acute post-operative orbital signs and symptoms.

The blue-light-blocking IOL had no effect on the sleep quality of patients, indicating that these IOLs might serve as an alternative to conventional IOLs without a detrimental effect on circadian rhythm.

An elderly man developed endophthalmitis 1 week after cataract extraction and lens implantation. Intraocular samples were collected and the patient received intravitreal vanco-mycin and ceftazidime, and topical tobramycin. A Gram stain of vitreous humour revealed spindle-shaped Gram-negative bacilli. He was then given systemic clindamycin and topical ofloxacin. Capnocytophaga canimorsus, a member of the oral flora of dogs and cats, was cultured after 3 days. The infection resolved leaving the patient with a visual acuity of 6/60. An attempt was made to culture the organism from the mouth of the patient's pet dog. This was unsuccessful and the source of the infection remains unknown.

We present a 52-year-old woman who was diagnosed with surgically induced necrotizing scleritis 48 years after strabismus surgery. This case demonstrates the importance of a high index of suspicion for this sight-threatening condition, even many years after strabismus surgery. J Pediatr Ophthalmol Strabismus 2005;42:180–182.
