Abstract Details

Purpose:

To compare the surgical outcome of excision with conjunctival autograft using fibrin glue versus sutures in primary double headed pterygium.

Setting:

Department of Ophthalmology, National University Hospital, Singapore

Methods:

In a retrospective comparative interventional case series surgical outcomes of primary double-headed pterygium were analysed. One group underwent excision with conjunctival autograft using fibrin glue. The conjunctival autografts were sutured in the other group. The conjunctival grafts were harvested from superior bulbar conjunctiva. A split graft technique was used in all cases. The epidemiological features were analysed and the outcomes were compared between the two groups.

Results:

Thirteen eyes of 11 patients with double-headed pterygium were identified. Fibrin glue and sutures were used in 9 (18 pterygiums) and 4 eyes (8 pterygiums) respectively to fix the autograft. The patients were predominantly male with mean age of 68.9 (± 14.6) years. The preoperative astigmatism (-2.65 D) reduced significantly after surgery at 6 months (-1.37D). The mean follow-up was 13.6 months. Although, there was no recurrences in fibrin glue group, 25% recurrences were noted in suture group. Visual acuity improved in all patients after pterygium surgery even though most of the patients had significant coexisting cataract and other ocular morbidities.

Conclusions:

Excision and conjunctival autograft using fibrin glue is an effective and superior procedure than suturing method in primary double-headed pterygium. Large graft can safely be harvested from superior bulbar conjunctiva.
