I can find the before, but not the after.
Patients with HCV are known to have higher Intra Occular Pressure (IOP) and other issues. IOP is measured with tonometry:
HCV-infected patients presented an almost four times higher risk of lacrimal function involvement by tear break-up time [odds ratio (OR)=3.76; 95% confidence interval (CI) 1.75-8.04, P=0.001] and Schirmer's test (OR=4.17; 95% CI 1.83-9.50, P=0.001) than the controls. The chances of palpebral biomicroscopic lesions (blepharitis) were also higher (OR=3.21; 95% CI 1.49-6.94, P=0.003). Mean tonometry was higher in HCV patients (right eye 14.4±2.3 vs. 12.2±1.5, P<0.001 and left eye 14.5±2.3 vs. 12.0±1.4, P<0.001).
