Table 2. GDNF concentrations in the biologic fluids (pg/ml) in cataract patients with and without POAG.

Biologic fluid Cataract with POAG group (n=30) Cataract group (n=47a)           P
Aueous humor                                    
     mean±SD           46.3±31.1           88.9±46.9           <0.001
     range           4.4–106.6           2.0–212.5 b            
     median (IQR)           47.7 (15.4–61.2)           83.0 (58.8–119.4)            
Lacrimal fluid                                    
     mean±SD           222±101           344±134           <0.001
     range           61–487           173–683            
     median (IQR)           218 (160–293)           312 (244–411)            
Blood serum                                    
     mean±SD           194±56           201±45           NS
     range           106–317           103–287            
     median (IQR)           180 (158–228)           196 (174–239)            

Statistical analysis was performed by Mann–Whitney U test POAG – primary open-angle glaucoma; SD – standard deviation; IQR – interquartile range; NS – non-significant a For lacrimal fluid n=46 (one case with extreme outlying value excluded) b In 3 cases, values below 4.0 pg/ml were substituted with half minimum quantifiable value (2.0 pg/ml); without these values range is 32.6–212.5 pg/ml
