Modified excision of pterygium combined with autogenous free bulbar conjunctival transplantation

Objective To investigate the therapeutic effect of using the method of improved pterygium excision,combined with autogenous free bulbar conjunctiva transplantation for the treatment of primary pterygium.Methods Limbus conjunctiva incision,tunnel-like separation of pterygium body,Subepithelial split of pterygium head,autogenous conjunctival transplantation to scleral defect.78 cases (90 eye) of primary pterygium surgery,were followed up in postoperative 6 ～ 12 months,averaging (9.85 ± 2.36) months.Results All reactions in patients were mild,without any special discomfort except slight pain and foreign body sensation 1 ～ 2 days after operation.Corneal epithelium was basically recovered in postoperative 3 ～ 4days,with negative fluorescent staining.Of the 78 cases (90 eyes),5 cases suffered from open of conjunctival wound upon demolition of suture due to early excessive eye movement,without shift and off,2 cases suffered from glaucoma,1 cases suffered from granulation hyperplasia on conjunctival wound on postoperative 15 days,1 case was found subconjunctival liquid uplift,local Lymphoma liquid retention 1 month after operation,4 eyes suffered from recurrence (recurrence rate 4.44％),without any other complications.Conclusion The improved excision of pterygium,achieves effect of small wound,slight reaction and faster healing.The excision of pterygium was complete and safety,combined with autogenous free bulbar conjunctival transplantation,with lower recurrence rate and worthing promoting.
