ABSTRACT OBJETIVO: Avaliar o efeito do 5-fluorouracil (5FU) injetado intralesionalmente na cabeça do pterígio no período pré-operatório. MÉTODOS: Foram estudados 53 olhos (52 pacientes), sendo 28 pterígios primários e 25 recidivados, divididos em dois grupos: grupo 1 (G1), composto por indivíduos que receberam a injeção de 5-fluorouracil 30 dias antes do procedimento cirúrgico e grupo 2 (G2), no qual o 5-fluorouracil foi injetado 10 dias antes da cirurgia. Todas as cirurgias foram realizadas seguindo-se a mesma técnica cirúrgica, pelo mesmo cirurgião. Os pacientes foram reavaliados 7, 30 e 60 dias após a cirurgia. Os resultados observados foram submetidos à análise estatística. RESULTADOS: A amostra estudada foi constituída por 52,8% de pterígios primários e 47,2% de recidivados, sendo composta igualmente por indivíduos de ambos os sexos. Não ocorreram complicações decorrentes da infiltração da droga. A recidiva foi mais freqüente nos pterígios recidivados e no G1. CONCLUSÃO: O uso intralesional de 5-fluorouracil no pré-operatório do pterígio não provocou efeitos deletérios aos olhos estudados. Houve menor recorrência quando usado o 5-fluorouracil 10 dias antes da exérese cirúrgica, em relação à aplicação 30 dias antes do procedimento.

    ABSTRACT: To investigate the safety and efficacy of intraoperative infiltration of 5-fluorouracil (5-FU) as an adjuvant drug in pterygium treatment. Of 125 consecutive patients, 125 eyes with primary and recurrent pterygium underwent pterygium excision with intraoperative 5-FU (25 mg/mL) infiltration. The superior and inferior conjunctiva was approximated to cover the scleral bed and 0.2 mL 5-FU was injected at the end of the surgical procedure. The gender, occupation, pterygium characteristics and the follow-up at 7, 21, 60 e 180 days after surgery were evaluated and the data were statistically analyzed. With follow-up of 180 days the patients had no serious complications observed during or after surgery. The relapse rate was 35.8% and occurred in primary (35.7%) and recurrent (36.4%) lesions with no statistical difference. This study suggests that intraoperative infiltration of 5-FU is safe. However the high recurrence rate indicated that other studies would be necessary to show the concentration/dose to better prevent it.

    ABSTRACT: To report the outcome of postoperative subconjunctival injection of triamcinolone in eyes that underwent pterygium surgery and were at risk for recurrence. Twelve eyes of 11 patients with primary (7 eyes) or recurrent (5 eyes) pterygia underwent excision and conjunctival autografting (4 eyes, 33.3%), amniotic membrane grafting (6 eyes, 50%), or both (2 eyes, 16.6%). All of these eyes had signs that were considered to be risk factors for recurrence (conjunctival inflammation, hemorrhage, granuloma, and fibrovascular proliferation); accordingly, they also underwent subconjunctival injection of triamcinolone. Among the 11 patients, there were 8 (72.7%) men and 3 (27.3%) women; the mean age was 41 years (range, 20-56 years). In 5 (41.7%) eyes, the pterygium was graded as T2 (intermediate) and in 7 (58.3%) eyes was graded as T3 (fleshy). The time between surgery and the first injection ranged from 2 to 5 weeks (mean, 3.4 weeks), and 1-3 injections were necessary (mean, 1.7) to achieve the desired effect. After injection, 1 (8.3%) eye developed inflammation, and 2 (16.7%) eyes from another patient developed intraocular hypertension that was controlled with a topical beta-blocker. The follow-up after the last injection ranged from 8 to 36 months (mean, 14.5 months); only 1 recurrence (grade 3) occurred during this period. The postoperative use of subconjunctival triamcinolone seems to benefit patients at increased risk of pterygium recurrence. It is relatively safe and is accompanied by few complications, but controlled and prospective studies are necessary to confirm its efficacy.
