Introduction:
Conjunctival Autograft (CAG) in pterygium surgery can be attached by sutures or fibrin glue or autologous in situ blood coagulum. Recurrence rate and other parameters related to pterygium surgery between CAG with sutures and autologous in situ blood coagulum have not been compared uniformly in advanced pterygia alone.
Aim:
To compare and evaluate the outcome of sutureless, glue-less CAG with autologous in situ blood coagulum versus CAG with sutures for primary, advanced pterygium.
Materials And Methods:
Thirty eyes of 30 patients with primary, nasal, advanced, Grade 3 pterygia (as per Tan et al's., classification) were randomized into Group 1 (n=15) (sutureless, glue-less CAG with autologous in situ blood coagulum) and Group 2 (n=15) (conjunctival autograft with 8-0 vicryl sutures) as a pilot study. The outcome parameters evaluated were graft stability and symptoms of pain, foreign body sensation and watering at day 1, day 7, day 14, one month, three months and six months and recurrence at six months.
Results:
The mean age in the study was 44.77±13.74 years. Overall, Group 1 had better scores in symptom parameters than Group 2 (p<0.05). Graft stability was better in Group 2 (p<0.05). In Group 1, 3 (20%) patients had one side displacement and 3 (20%) patients had full displacement of graft. At six months, 4 (26.6%) patients in Group 1 had recurrence whereas in Group 2, 5 patients (33.3%) had recurrence (p=0.446).
Conclusion:
In primary, advanced pterygia, sutureless, glue-less pterygium surgery with autologous in situ blood coagulum was better in symptom scores but graft stability was better in the suture group. Sutureless, glue-less pterygium surgery with autologous in situ blood coagulum was unpredictable in graft stability. There was no statistically significant difference in the recurrence rate between the two groups.
