Examining the blood profile of patients with pterygium ('surfers eye') compared with healthy volunteers

Detailed systemic and ophthalmic history of the participants were obtained and all subjects were underwent comprehensive ophthalmic examination. Complete blood count analysis was carried out for the pterygium patients and healthy control subjects. Blood analysis was carried out a week before the excision surgery for pterygium patients. Neutrophil, lymphocyte, monocyte and platelet counts, and mean platelet volume measurements was performed within 2 hours after collection of blood samples with an automatic analyzer. The neutrophil to lymphocyte ratio , monocyte to lymphocyte ratio and platelet to lymphocyte ratio were calculated by dividing the neutrophil count by lymphocyte count, monocytes count by lymphocyte count and platelet count by lymphocyte count respectively.The pterygium patients classified into 3 subgroups as atrophic, fleshy and intermediate according to Tan’s classification. All the obtained parameters were compared between the groups and among the subgroups statistically.
