2BACKGROUND
- Conjunctival autografting after pterygium
excision is associated with very low rates of
recurrence. - Disadvantages of graft suturing include longer
surgery duration (vs. bare sclera technique),
potential for granuloma formation and giant
papillary conjunctivitis, and patient discomfort. - Fibrin-based adhesives for the attachment of
conjunctival grafts have been associated with
shorter surgery duration, improved patient
comfort, and fewer complications. However, the
recurrence rates with the use of fibrin glue have
been investigated in few studies, the results of
which have been inconsistent.
3PURPOSE
- To determine the safety and efficacy of using
fibrin glue (Tisseel VH, Baxter) to attach
conjunctival autografts - To compare the results with the use of nylon
sutures in patients undergoing primary pterygium
excision
4STUDY DESIGN
- A retrospective case series was conducted of 23
eyes (23 patients) who underwent primary
pterygium excision with conjunctival autograft
between 2007 and 2009 at CHUM Hôpital Notre Dame
in Montreal, Canada. Patients with autoimmune
disease, a history of previous ocular surgery or
trauma, and those who received intraoperative
Mitomycin C were excluded from this study.
5METHODS
- Of the 23 eyes that had undergone pterygium
surgery, 12 conjunctival autografts were attached
using fibrin glue by residents under the
observation of one surgeon, and another 12
autografts were sutured in place with 10-0 nylon
sutures by a different attending surgeon. A chart
review was conducted and patients were reexamined
to evaluate differences in - operating time
- graft success (graft intact 4 weeks
postoperatively) - pterygium recurrence (growth 1 mm onto cornea)
- postoperative patient comfort

9CONCLUSION
- This study suggests that fibrin glue attachment
of conjunctival autografts in primary pterygium
excision surgery is effective and safe. The
fibrin group showed less discomfort and slightly
shorter operating time (with residents operating
the majority of time in this group) as compared
with the standard nylon suturing technique.
However, the fibrin group resulted in a higher
rate of recurrence. None of these differences was
statistically significant. A larger study with
the same surgeon performing both surgical
techniques may be beneficial in determining
whether recurrence is more frequent with the use
of fibrin glue.
