Vascular Endothelial Growth Factor (VEGF) Serological and Lacrimal Signaling in Patients Affected by Vernal Keratoconjunctivitis (VKC)

Table 2

Comparisons of the 2 groups after using the VEGF EIA kit for vascular endothelial growth factor (VEGF) concentration.

VKC group ()	Control group ()	value
VEGF tears in pg/mL: 12.13 ± 5.54	Tears in pg/mL: 7 ± 4.76	<0.05 (0.011)
VEGF serum in pg/mL: 45.17 ± 18.67	Serum in pg/mL: 38.08 ± 19.43	NS > 0.05 (0.29)

SD: standard deviation; NS: not statistically significant. The values are expressed as mean ± SD. A statistically significant difference was found in tear samples (). No statistically significant difference was found when comparing VEGF concentration in blood samples ().
