Top-Nine from the Canadian Glaucoma Society

The prevalence of pseudo-exfoliation syndrome in Tamil people (>45 years) living in Toronto was 4.1% (11.5% at 65 years or more). The prevalence of POAG was 5.7%, but only 32.5% were associated with PXS. PXF glaucoma was found in 47.6% of those with PXS.
Optic nerve head hemorrhages were found in 28% of patients on anticoagulants. There was no association with systemic disease.
A five-year randomized study comparing selective laser trabeculoplasty with argon laser trabeculoplasty reported similar results for both modalities.
No correlation was found between the severity of glaucoma and the amount of pseudoexfoliation material.
In pseudoexfoliation syndrome, four extracellular matrix genes were over expressed, while one gene was under expressed.
POAG patients had a higher IOP response to cycloplegia than normals, which in most cases was attributed to the use of miotics.
G-probes can be used safely up to at least 30 times.
Disease stability is correlated with lower IOP and there may be a relationship with the lower cost of therapy.
The blood flow in the neuroretinal rim of ONHs with a CDR of more than 0.4 was significantly lower than in those with a CDR of less than 0.4 (laser Doppler flowmetry).
