Diagnostic accuracy of non-mydriatic fundus photography as a triage and telemedicine tool for patients with vision loss.

Objectives: Fundoscopy can be challenging for non-ophthalmologists. For emergency physicians, non-mydriatic fundus photography is superior to other forms of ophthalmoscopy in sensitivity, specificity, and inter-examination agreement. We report on a prospective cross-sectional study evaluating the use of non-mydriatic photography as a triage and telemedicine tool for patients with vision loss in a Canadian emergency setting.

Postoperative Complications of Pars Plana Vitrectomy for Diabetic Retinal Disease.

Despite recent advances in the medical management of diabetic retinal disease, there remain established indications for vitreoretinal surgery in the treatment of severe proliferative diabetic retinopathy. These include non-clearing vitreous hemorrhage and tractional retinal detachment. Advances in surgical instrumentation, technique, and experience have led to improved visual outcomes, as well as a corresponding decrease in the incidence of postoperative complications.

Forceps trauma in a newborn presenting as iris heterochromia.

Birth-associated ocular trauma is common and often minor, including subconjunctival and retinal haemorrhage and eyelid edema. Significant ocular trauma during birth, usually associated with forceps-assisted delivery, is rarer and can include Descemet's membrane rupture, lid lacerations, hyphema, Purtcher retinopathy, facial nerve palsy, corneal edema, and corneal laceration. We report the first case of ocular birth trauma from forceps presenting as isolated iris heterochromia and a pseudo rubeosis iridis, which completely resolved by 1 month of age with no known adverse ocular sequelae.

A child with rapidly progressive necrotizing group a streptococcal Tenon's capsule infection one day after strabismus surgery.

Periorbital infections after strabismus surgery are rare. We describe the first reported case of necrotizing group A streptococcal infection of the conjunctiva and Tenon's capsule complicating uneventful strabismus surgery in a 23-month-old boy, successfully managed with conservative intraoperative debridement and with targeted local and systemic antibiotics.

Peripapillary RNFL thickness in nonexudative versus chronically treated exudative age-related macular degeneration.

Objective: To compare the peripapillary retinal nerve fibre layer (RNFL) thickness in nonexudative versus exudative age-related macular degeneration (wet AMD) eyes treated chronically with intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF).

Design: Cross-sectional study.

Participants: Twenty-nine patients with unilateral wet AMD with at least 12 prior intravitreal anti-VEGF injections and 2 years of therapy were analyzed.

Delayed Development of Intracranial Hypertension After Discontinuation of Tetracycline Treatment for Acne Vulgaris.

A 14-year-old girl presented with a history of left-sided headache and acute bilateral blurred vision. She had a remote history of oral tetracycline use for the treatment of acne vulgaris, which had been discontinued for 1 month. The patient was diagnosed with drug-induced intracranial hypertension (IH) and treated with oral acetazolamide with subsequent resolution of symptoms.

Family physicians' perspectives on personal health records: qualitative study.

Objective: To explore FPs' perspectives on the value of personal health records (PHRs) in primary care and the implementation and adoption of PHRs in Canada.

Design: A qualitative design using semistructured interviews.

Setting: Southwestern Ontario.

The impact of post-mastectomy radiation therapy on male breast cancer patients--a case series.

Objective: To assess the impact of radiation management on male breast cancer (MBC) at London Regional Cancer Program (LRCP).

Methods And Materials: Men with a diagnosis of breast cancer referred to LRCP were reviewed. The seventh American Joint Committee on Cancer staging system was used.

Brachytherapy with permanent gold grain seeds for squamous cell carcinoma of the lip.

Purpose: To describe the use of radioactive gold grain implantation for squamous cell carcinoma of the lip.

Methods: Retrospective review of 51 patients treated with permanent gold ((198)Au) grain implant brachytherapy. The seed arrangement delivered a dose of 5500 cGy at 0.

Intravitreal injection anesthesia--comparison of different topical agents: a prospective randomized controlled trial.

Purpose: To compare the anesthetic effectiveness of 3 topical agents used for intravitreal injections.

Design: Randomized, triple-armed, double-blinded, prospective, single-centered trial in patients receiving intravitreal ranibizumab for neovascular age-related macular degeneration.

Methods: Patients were randomized 1:1:1 to receive 0.

Systematic review of baseline low-dose CT lung cancer screening.

The purpose of this systematic review was to provide physicians and patients with a synthesis of the available data and an assessment of the operating characteristics associated with baseline LDCT screening for lung cancer. Various databases, meeting abstracts, clinical trials in progress, and major textbooks for relevant data from 1966 to 2006 were searched for relevant studies. The median value of sensitivity, specificity, positive predictive value and negative predictive value were 81%, 81%, 8% and 99%, respectively.
