About Us

The Canadian Retina Society is composed of members of the Canadian Ophthalmological Society whose primary area of patient care consists of surgical and/or medical vitreoretinal (VR) disease.

Our Mission Statement

The mission of the Canadian Retina Society is to maintain the highest quality of patient care and teaching, particularly as it relates to the investigation and treatment of vitreoretinal (VR) disease; promote the interchange of information and scientific material and facilitate meetings of those who have a special interest in the diagnosis and management of VR pathology; work with the Canadian Ophthalmological Society on matters relating to health advocacy, health policy, and clinical guidelines on a national level.

Snapshot of the Month

Fundus examination OD revealed a whitened posterior pole with sparing in the papillomacular bundle. Spectral-domain optical coherence tomography OD revealed inner retinal hyperreflectivity with fovea sparing.

Description:

A 80-year-old female experimented nasal visual field loss in her right eye (OD) with preserved temporal visual field. Her past medical history was significant for age-related macular degeneration and hypertension. Best-corrected visual acuity was 6/6 OD and 6/9 OS. A pupillary afferent defect was present OD. Slip lamp examination was unremarkable in both eyes. Fundus examination OD revealed a whitened posterior pole with sparing in the papillomacular bundle. Spectral-domain optical coherence tomography OD revealed inner retinal hyperreflectivity with fovea sparing (Fig 1A). Fluorescein angiography showed a central retinal artery occlusion (CRAO) with cilioretinal sparing OD (Fig 1B).

Cilioretinal artery is an anatomic variant found in 15 to 30% of the population that often supplies the papillomacular bundle, but that supplies the foveola in only 10% of eyes 1, 2. Therefore, its presence and specifically its distribution makes it possible of maintaining central vision in the event of a CRAO 2, 3, 4.
