Drug-prescribing patterns among optometrists and nonophthalmologist physicians at a tertiary care centre in Kingston, Ontario.

Objective: To report on patterns of optometry prescribing and adherence to prescribing regulations at a tertiary care ophthalmology centre.

Design: Prospective cohort study.

Participants: All new referrals from optometrists and other health care professionals to the emergency eye care service (n = 1965) between July 2011 and June 2012, as well as optometry referrals to 2 subspecialty services (glaucoma [n = 71] and cornea [n = 212]).

Strabismus surgical subspecialization: a population-based analysis.

Importance: The growing complexity of medical and surgical care has resulted in increasing subspecialization. To date, data have been lacking regarding the degree to which subspecialization has affected the provision of strabismus surgical services. This gap is important to address given the implications for health care human resources planning and educational programs.

Adverse gastrointestinal events with intravitreal injection of vascular endothelial growth factor inhibitors: nested case-control study.

Background: Intravenous administration of vascular endothelial growth factor (VEGF)-inhibiting drugs is associated with adverse gastrointestinal (GI) events. Clinical trials of VEGF inhibitors used for the treatment of retinal diseases have suggested higher risks of adverse GI events among patients treated with bevacizumab. However, population-based studies have been lacking.

Clinic-based glaucoma care in the era of surgical subspecialization.

Purpose: To evaluate the impact of surgeon practice profile on clinic-based glaucoma care.

Design: Population-based study of glaucoma care patterns in Ontario, Canada from 2000-2010.

Methods: Using comprehensive physician services data from the Ontario Health Insurance Plan database, ophthalmologists were divided into 5 surgical practice subgroups.

Systemic effects of intravitreal vascular endothelial growth factor inhibitors.

Purpose Of Review: The development of vascular endothelial growth factor (VEGF) inhibitors has revolutionized the treatment of retinal diseases. However, VEGF functions in many physiological and pathological processes. Consequently, inhibition of this signalling molecule carries the potential to cause serious adverse events.

New surgical technique for correcting tube-iris touch following glaucoma drainage implant surgery.

Glaucoma drainage implant surgery may be associated with a number of potential complications including tube malpositioning. This malpositioning may have serious sequelae such as corneal endothelial damage, chronic iritis, cataract formation or tube occlusion. Traditional management of tube malpositioning involves major surgical re-dissection and reinsertion of the tube.
