Pterygium of Both Eyes Clinical Trial
Official title:
Comparative Study of Concentration of Muc5ac and Muc2 Mucins in Tear Film in Surgical Treated Pterygia With Amniotic Membrane Transplantation vs. Conjunctival Autograft
To identify and compare the differences in the concentration of the Muc2 and Muc5AC mucins in tear film in patients who underwent pterygium surgery using amniotic membrane transplantation and conjunctival autograft surgery.
Patients with nasal, primary pterygium bigger than 1 mm of corneal invasion with residence in Mexico City and older than 18 years were included. Under informed consent, patients were divided into two groups in a random fashion. Pterygium surgery was carried out with conventional technique performing amniotic membrane transplantation for group A, and conjunctival autograft for group B. Muc2 and muc5ac mucin concentration was measure min tear film by ELISA; samples were taken before surgery, at first, third and sixth month postoperatively. BUT was also measured on the same dates. Descriptive statistics and the U-Mann Whitney test for independent groups, considering a p≤0.05 as significant were used for analysis. ;
