Aim- To observe recurrence rate after conjunctival limbal autograft (CLAU) and tocorrelate
this with preoperative histopathological and morphologicalcharacteristics of pterygium.
Design: Interventional, Prospective, Hospital-Based Study.
Methods: 107 patients with primary pterygium were examined, managed by CLAU and
histopathology sample sent. The outcomes were assessed in terms of clinically significant or
insignificant recurrence till 6 months follow-up.
Results: 57% patients were female. 17.8% participants had Stockers Line and all patients
having stocker’s line had stationary type of pterygium. Fuchs spots were seen in 4.7% of
patients. Histopathology findings includeEpithelial Hyperplasia (80.4%), Vascularity
Overwhelms Fibrosis (39.1%), Vascularity Similar to Fibrosis (28.3%), Fibrosis Overwhelms
Vascularity (34.8%), Perivascular Stromal Inflammation (54.3%), Diffuse Stromal
Inflammation (37.0%). The following variables were significantly associated (p<0.05) with
the Recurrence: Age, Fuchs Spots, higher vascularity and Diffuse Stromal Inflammation on
Conclusion: Factors such as younger age group,higher redness and thickness of pterygium,
Fuchs Spots, higher vascularity and diffuseinflammation on histopathological examination
can be considered as a risk factor for recurrence. However, occupation, laterality, location
and type of pterygiumwere found not to be related to recurrence.
