TNF-alpha levels were significantly higher in the glaucoma group than in the cataract group, with a particularly large difference observed in those with ExG. The results suggest that TNF-alpha plays a key role in the progression of glaucoma.

Overall, clusters in the lower hemifield in the better eye were more strongly correlated with QOL than those in the worse eye. In particular, the lower paracentral visual field in the better eye was correlated most strongly of all. Driving, however, strongly correlated with the upper hemifield in the better eye.

A significant relationship was found between QOL and both the VFI and MD, but the VFI had a marginally better correlation than that of MD. While QOL was better related with visual field loss in the better eye than in the worse eye, the difference was not large. Not much of a difference was found in the status of QOL between NTG patients and POAG patients.

Significant increases in the levels of SOD activity and total protein correlated with the severity of the cataract but not with patient age, suggesting that progressed cataract is associated with molecules leaking from the lens capsule.

The switch from the concomitant use of latanoprost 0.005% and timolol maleate 0.5% eye drops to latanoprost 0.005%/timolol maleate 0.5% combination eye drops improved adherence and helped maintain IOP.
