Exposure to Euphorbia lathyris latex resulting in alkaline chemical injury: a case report.

INTRODUCTION: We report the case of a patient with extreme pain following accidental exposure to the latex of Euphorbia lathyris. CASE PRESENTATION: A 76-year-old Caucasian woman attended the ophthalmology department with acute severe bilateral eye pain. This occurred immediately after having pulled a weed out of her garden with her bare hands. She recalled having subsequently rubbed her eyes. The offending plant, was brought into hospital and was identified as the Caper Spurge (Euphorbia lathyris). Her ocular pH was alkaline (pH 9). After copious irrigation, the pH normalised. She was treated with topical steroids, cycloplegics, lubricants and opioid oral analgesia. Three days later, she was symptom-free and her vision had returned to normal. CONCLUSION: Exposure to Caper spurge latex is a rare cause of keratoconjunctivitis. It can, however, potentially lead to corneal ulceration, anterior uveitis and rarely blindness. Treatment remains largely empirical. Exposure to the milky latex can result in extreme pain requiring prompt treatment. The use of goggles and gloves is recommended when handling this plant.

Optic atrophy, necrotizing anterior scleritis and keratitis presenting in association with Streptococcal Toxic Shock Syndrome: a case report.

INTRODUCTION: We report a case of optic atrophy, necrotizing anterior scleritis and keratitis presenting in a patient with Streptococcal Toxic Shock Syndrome. CASE PRESENTATION: A 43-year-old woman developed streptococcal toxic shock syndrome secondary to septic arthritis of her right ankle. Streptococcus pyogenes (b-haemolyticus Group A) was isolated from blood cultures and joint aspirate. She was referred for ophthalmology review as her right eye became injected and the pupil had become unresponsive to light whilst she was in the Intensive Therapy Unit (ITU). The iris appeared atrophic and was mid-dilated with no direct or consensual response to light. Three zones of sub-epithelial opacification where noted in the cornea. There where extensive posterior synechiae. Indirect ophthalmoscopy showed a pale right disc. The vision was reduced to hand movements (HM). A diagnosis of optic atrophy was made secondary to post-streptococcal uveitis. She subsequently developed a necrotizing anterior scleritis. CONCLUSION: This case illustrates a previously unreported association of optic atrophy, necrotizing anterior scleritis and keratitis in a patient with post-streptococcal uveitis. This patient had developed Streptococcal Toxic Shock Syndrome secondary to septic arthritis. We recommend increased awareness of the potential risks of these patients developing severe ocular involvement.

Vitreous and subretinal haemorrhage: an unusual complication of retinal racemose haemangioma.

Racemose haemangioma of the retina is a rare, usually unilateral developmental abnormality: an arteriovenous communication with variable alterations in capillary and arteriolar networks. Herein a case of a 57-year-old man with a vitreous and subretinal haemorrhage in the left eye is described.
