Abstract Details

Purpose:

To compare visual outcome, complications, recurrence rates, and patient satisfaction with the use of fibrin glue versus sutures in pterygium excision surgery performed with conjunctival auto-grafting for the treatment of primary and recurrent pterygium.

Setting:

University Hospital of North Staffordshire NHS Trust, Staffordshire, ST4 6QG, UK

Methods:

This observational study included 43 eyes from 40 patients who underwent excision of pterygium and conjunctival autograft at a single tertiary institution by the same surgeon between 2008 and 2014. Medical records were retrospectively reviewed for age, sex, best-corrected visual acuity (BCVA, logMAR), intra-operative data, surgical complications, and recurrence rate at last follow-up. Patient satisfaction was assessed via a telephone questionnaire.

Results:

Thirty eyes underwent pterygium excision with suture (8/0 Vicryl and 10/0 Nylon) and fibrin tissue glue were used in 13 eyes. Follow-up ranged from 1 to 36 months (median 12 months). There were 4 recurrences (13.3%) in the suture group and none in the fibrin group. There were 2 cases of graft dehiscence in the fibrin group (15.4%), and none in the suture group. No significant surgical complications were reported. Survey results indicated higher levels of patient satisfaction in the fibrin group. Demographics, changes in BCVA, pre-operative and follow-up clinical characteristics of patients revealed no significant differences.

Conclusions:

The use of fibrin glue in pterygium excision with conjunctival autografting is associated with lower recurrence rate and higher levels of patient satisfaction compared with the use of the traditional suturing technique. Future studies with larger cohorts may be carried out to determine longer term results.
