Purpose : To evaluate bleb morphology after novel “Conjunctival frill/Smile” incision trabeculectomy vs conventional flap surgery.
Method : 60 trabeculectomy patients were subjected to conjunctival frill incision (Study group), made 1.5 -2.0 mm from limbus sutured with running, horizontal mattress suturing vs fornix based flap (Control). Bleb evolution was studied over 6-month period by IBAGS & AS-OCT.
Results : Bleb morphology was similar regarding extent, vascularity in two groups with moderate bleb height (H2) being more frequent in study group. Quantitative bleb assessment by AS-OCT documented bleb wall thickness as 115-127 µ and 114-121 µ in study vs control, bleb height reduced from 242 to 230 µ after attaining bleb maturity in control group, with more number of microcysts (15 vs 13 out of 30) in study group.
Conclusion: Conjunctival frill incision generates a functional healthy bleb with better wall thickness, increased internal reflectivity at intermediate follow up of 6 months.
