Background:
New laser and surgical techniques have had a significant effect on glaucoma therapy. A precise understanding of how these developments are affecting overall glaucoma management is fundamental to health services planning. The objective of this study was to synthesize Canadian national and provincial data regarding glaucoma laser and surgical procedure rates from 1992 to 2004.
Methods:
Canadian provincial health insurance databases, which cover virtually all surgical procedures provided domestically to Canadians, were accessed to ascertain yearly total glaucoma procedure numbers. To estimate the number of individuals with glaucoma, an age-stratified glaucoma prevalence model was applied to population census data.
Results:
Laser trabeculoplasty rates dramatically increased between 2001 and 2004 with the national Canadian rate more than doubling. However, this increase varied widely across regions, ranging from 0% to 530%. Trabeculectomy surgery rates slowly increased from 1992 to 1995, then declined by 29% nationally between 1995 and 2004. Implantation rates of glaucoma drainage devices increased 12-fold nationally between 1992 and 2004; by 2004 this procedure accounted for 10% of incisional glaucoma surgical procedures in Canada.
Interpretation:
In Canada, laser trabeculoplasty rates have risen significantly over recent years. Trabeculectomy rates have recently declined, and implantation of glaucoma drainage devices is playing an increasingly important role in glaucoma management in this country.
Insights
Glaucoma laser trabeculoplasty rates have significantly increased in Canada, while trabeculectomy surgery rates have declined. Glaucoma drainage device implantation is becoming more common in patient treatment.
Area of Science:
- Ophthalmology
- Health Services Research
- Medical Procedure Analysis
Background:
- Glaucoma management is evolving with new laser and surgical techniques.
- Understanding trends in glaucoma procedures is crucial for health service planning.
- This study analyzes Canadian national and provincial glaucoma procedure data from 1992 to 2004.
Purpose of the Study:
- To synthesize Canadian national and provincial data on glaucoma laser and surgical procedure rates.
- To track changes in glaucoma treatment modalities over a 13-year period.
Main Methods:
- Utilized Canadian provincial health insurance databases for surgical procedure data.
- Applied an age-stratified glaucoma prevalence model to population census data to estimate patient numbers.
Main Results:
- Laser trabeculoplasty rates more than doubled nationally between 2001 and 2004, with significant regional variation (0%–530%).
- Trabeculectomy rates increased from 1992-1995, then declined 29% nationally by 2004.
- Glaucoma drainage device implantation rates increased 12-fold nationally (1992-2004), representing 10% of incisional surgeries by 2004.
Conclusions:
- Laser trabeculoplasty has seen a significant rise in recent Canadian use.
- Trabeculectomy rates have declined, with glaucoma drainage devices becoming increasingly vital in Canadian glaucoma care.
