Abstract

Purpose : To assess differences in translaminar pressure difference (TPD), and ocular hemodynamic parameters between normal-tension (NTG) and high-tension (HTG) glaucoma, ocular hypertension (OH) and healthy subjects (HS).

Methods : 100 NTG (57.5(10.9)yr), 100 HTG (57.5(10.9)yr), 40 OH (47.0(9.6)yr) and 100 HS (57.4(10.6)yr) were assessed for: intraocular pressure (IOP), non-invasive intracranial pressure (ICP, via Vittamed UAB, Lithuania), resistance indexes (RI) in the ophthalmic (OA), central retinal (CRA), temporal short posterior (tSPA) arteries (color Doppler imaging, Accuvix, Korea), blood pressure (BP) and body mass index (BMI). TPD was calculated as: TPD=IOP–ICP. Results of p<0.05 were considered statistically significant.

Results : HS had statistically significantly lower TPD, compared to NTG, HTG, and OH (3.6(2.1), 6.3(2.6), 17.7(5.4) and 13.5(3.4) mmHg, respectively, p<0.05). NTG was associated with TPD>4.68mmHg (odds ratio, OR:6.018; 95%confident interval, CI:3.263-11.097), OA RI>0.705 (OR:3.667; 95%CI:2.012-6.682), CRA RI>0.605 (OR:4.056; 95%CI:2.235-7.359), tSPCA RI>0.475 (OR:3.622; 95%CI:1.995-6.567), p<0.05 (discriminating HS and NTG). Comparing HTG and HS, TPD value>8.83mmHg was found in 99% HTG and 0% in HS, p<0.001. HTG was associated with CRA RI>0.605 (OR:3.174; 95%CI:1.757-5.733), tSPCA RI>0.485 (OR:3.995; 95%CI:2.211-7.215), diastolic BP>83.0mmHg (OR:2.613; 95%CI:1.466-4.658), BMI>28.8kg/m2 (OR:2.267; 95%CI:1.218-4.217), p<0.05(discriminating HS and HTG). Comparing NTG and HTG it was found that OA RI>0.705 was associated with NTG (OR:1.839; 95%CI:1.002-5.372), p<0.05. Comparing OH and HS TPD value>8.65mmHg was found in 97.5% OH and 0% HS, p<0.001. OH was associated with OA RI>0.685 (OR:4.827; 95%CI:1.862-12.517), tSPCA RI>0.485 (OR:3.030; 95%CI:1.410-6.511), p<0.05 (discriminating healthy subjects and OH). Comparing HTG and OH it was found that TPD>15.34mmHg was associated with HTG (OR:5.824; 95% CI:2.548-13.311), p=0.01.

Conclusions : Lower TPD was associated with higher risk of NTG, while higher TPD was associated with OH and HTG. Higher OA RI was associated with NTG. Further studies are analyzing TPD in glaucoma management are warranted.
