Canadian Eye Injury Registry

Completed

• Conditions: Eye Injuries
• Interventions: Behavioral: Public Health strategies

• Registration Number: NCT01490593
• Lead Sponsor: Lawson Health Research Institute

Brief Summary

The purpose of this study is to establish an eye injury registry to assess the mechanisms and outcomes of significant eye injuries occurring in Canada. The epidemiologic data will determine where public health strategies should be directed to prevent future eye injuries.

Detailed Description

Currently there is no established database or recording system of eye injuries occurring in Canada. Estimates place the figure at approximately 100000 significant eye injuries occurring in our country every year. This represents a large public health and long-term disability challenge. Lost productivity of working-age individuals with vision loss amounts to $4.4 billion annually in Canada, part of which is due to eye injury. By recording the types, locations, and outcomes of significant eye injuries, it is hoped improved public health strategies may be established to prevent further ones. The need for such a database has been recognized by the Ivey Eye Institute, the Canadian National Institute for the Blind (CNIB) and the Canadian Ophthalmological Society (COS).

The United States Eye Injury Registry (USEIR) has been in existence for greater than 20 years. Through their database they have recorded thousands of eye injuries which has led to public health interventions through their various ocular societies. They have also established a standardized reporting system and ocular trauma score which has improved diagnosis and prognosis of eye injuries. This system has been used in many countries as a standardized reporting scheme for eye injuries.

It is hoped that through a pilot recording system established in London a framework for a national reporting system will develop. The objective is to use the standardized reporting system of the USEIR to report Canadian eye injuries.

The time frame for outcome measures will be 6 months. The patients will be followed along for this amount of time to assess there visual outcomes. No further follow up after 6 months will be undertaken for the purpose of the registry.

The hypothesis is that by recording the type and outcome of eye injuries, a better understanding of mechanisms and location of these injuries in Canada will occur. Subsequent public health interventions can then be made in conjunction with the CNIB and COS to improve eye health in Canada.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 104

Inclusion Criteria

• Any patient who experiences an acute eye injury that has or has the potential to compromise the integrity of the eye. These are serious eye injuries resulting in permanent and significant (i.e. measurable or observable on routine eye examination) structural or functional change to the eye. Separate reports are to be filed for each eye involved in bilateral injuries.

Exclusion Criteria

• Based on the standard of the United States Eye Injury Registry
• Mild ocular contusions
• Subconjunctival hemorrhage
• Superficial abrasions by themselves usually would not meet the criterion of serious and/or reportable injuries.
• The exclusion of these injuries will depend on the clinical judgement of the reporting physician.

Study & Design

• Study Design: Not specified

Arm && Interventions

Group	Intervention	Description
Patients with Eye Injuries	Public Health strategies	The database is being established to record the number and types of eye injuries occurring in Canada. Thus there is only one cohort group, individuals who have sustained an eye injury.

Primary Outcome Measures

Name	Time	Method
Number and type of eye injuries occurring in Canada	6 months	To record and determine the types and epidemiologic data of eye injuries in Canada.

Secondary Outcome Measures

Name	Time	Method
Ocular Trauma Score	6 months	To determine the correlation between the ocular trauma score as defined by the American Society of Ocular Trauma and the actual visual outcomes of Canadian Eye Injury patients
