ABSTRACT The use of conjunctiva autograft, adjunct antimetabolite therapy has been shown to be effective in preventing pterygium recurrence.
To compare 5 fluorouracil (5-FU) to conjunctival autograft in the treatment of large, fleshy pterygium.
A randomised controlled prospective study of outcome of pterygium treatment using 5-FU as adjuvant treatment compared to conjunctiva autograft. Thirty-five eyes with large pterygium treated with bare sclera conjunctival excision plus 5-FU were compared with 33 eyes treated with excision and conjunctival autograft alone.
Post-operative pterygium recurrence was observed in four (11.4%) eyes treated with 5-FU and 4 (12.1%) eyes treated with conjunctiva autograft (P>0.05). The post-operative complications included, granuloma formation 11.4% for 5-FU and 3.0% for autograft and conjunctival discharge 5.7% for 5-FU group only.
5-FU is marginally superior to conjunctival autograft in the prevention of pterygium recurrence but neither gives a more desirable single digit recurrence rate. Randomised studies combining both conjunctival autograft and 5-FU in pterygium treatment is advocated to further explore their effect.

    ABSTRACT: Objective: The objective of this study is to present the 3 months results of pterygium excision with adjunctive amniotic membrane graft. Materials and Methods: In a non-comparative case series study, the medical records of all patients who had pterygium excision with adjunctive amniotic membrane transplant on bare sclera from December 2009 to August 2010 were reviewed. All the patients were followed up for 3 months. The data collected were sex, age, occupation, type of pterygium (primary or recurrent), extent of pterygium, post-operative complications and recurrent pterygium growth. Results: Thirty eyes of 30 consecutive patients were operated on. There were 14 males and 16 females (M:F =1:1); age range 25 to 70 years (mean: 48.3 SD + 12.01). Twenty-six eyes had primary and 4 recurrent pterygia. Stage 3 pterygium accounted for most of the cases (53.3%) followed by stage 2 (36.7%) and stage 4 (10%). Nineteen patients (63.3%) had occupations with considerable exposure to actinic damage. Of these, manual laborers accounted for the highest number contributing 13 (43.3%) out of the 19 cases. Of the 30 patients 2 had a reoccurrence giving a recurrence rate of 6%. One patient developed dellen 1 week post-operatively with complete resolution following conservative large soft contact lens application. Conclusion: Short term results suggests that adjunctive amniotic membrane transplant with pterygium excision is effective and safe. A larger randomized clinical trial with a longer follow-up period is however recommended.

    ABSTRACT: PurposeTo evaluate the local safety of bevacizumab and its effect on recurrence of primary pterygium excision.MethodsThis randomized, placebo-controlled clinical trial was conducted on 44 eyes of 44 patients randomized to Group 1 (bevacizumab) and Group 2 (balanced salt solution). Group 1 underwent pterygium excision with a rotational conjunctival flap and received a total of 7.5 mg subconjunctival bevacizumab (5 mg/0.2 mL on the day of surgery and 2.5 mg/0.1 mL on the fourth day after surgery). Group 2 received balanced salt solution in the same manner. Recurrence, defined as any fibrovascular tissue crossing the limbus, and the number of patients with >1.5 mm fibrovascular overgrowth on the cornea were compared between the study groups.ResultsThere was no statistically significant difference between the study groups in terms of demographics, pterygium size, daily sun exposure, preoperative visual acuity, keratomeric readings, corneal astigmatism, or IOP (P>0.05). Three and four patients in each group at the three- and six-month visits, respectively, had more than 1.5 mm fibrovascular tissue overgrowth on the cornea (P=1 and 0.62, respectively). At the three-month visit, 3 patients in Group 1 versus 7 patients in Group 2 (P=0.13), and at the six-month visit 4 patients in Group 1 versus 8 patients in Group 2 (P=0.17) had fibrovascular tissue crossing the limbus. Patients in Group 1 experienced a statistically significant rise in IOP at the one-week visit (P=0.007).ConclusionBevacizumab had no significant effect on the recurrence rate of pterygium. Although the frequency of fibrovascular tissue crossing the limbus in the bevacizumab group was half that of the BSS group, the difference failed to reach a statistically significant level.

    ABSTRACT: AimRecurrence is the most common complication arising from pterygium surgery. The aim of this study was to investigate the effectiveness of 5 fluorouracil (5FU) in halting the recurrence of pterygium after surgical excision.MethodsA retrospective review of patients treated for pterygium recurrence was carried out. Patients with recurrent (secondary) pterygium were treated with multiple weekly intra-lesional injections of 0.1-0.2 ml (2.5-5 mg) 5FU post-operatively depending on the size of the recurrence. The treatment was started within 1 month from the date of recurrence. The time from surgery to start of recurrence, previous treatment modalities, and number of recurrences were documented. The number of injections required to induce arrest of progression and/or regression of vascularity and fleshiness of the pterygium and any complications related to 5FU treatment were examined.ResultsFifteen eyes from 14 patients with recurrent pterygium treated with intra-lesional 5FU injections were analysed. Three of the 15 eyes had undergone a secondary excision and 12 had undergone a primary excision. In all, 93.3% of patients showed regression of the fibrovascular tissue (thickness and vascularity) and arrest of progression following a dose of 0.1-0.2 ml (2.5-5 mg) 5FU. Twelve eyes required three injections or fewer, whereas one patient required eight injections. This beneficial effect was maintained over an average follow-up period of 17 months. No complications from 5FU were observed.Conclusion The use of weekly intra-lesional 5FU injections for the treatment of recurrent pterygium is safe and effective in limiting the progression and inducing the regression of recurrent pterygium. The number of injections can be tailored according to clinical need.Eye advance online publication, 28 June 2013; doi:10.1038/eye.2013.135.
