    Subconjunctival Bevacizumab in The Impending Recurrent Pterygia
    (2014) Bayar, Sezin Akca; Kucukerdonmez, Cem; Oner, Ozlem; Akova, Yonca A.; https://orcid.org/0000-0001-5109-755X; 24026871; AAJ-2406-2021
    The aim of this study is to evaluate the efficacy and safety of subconjunctival bevacizumab injection(s) in the treatment of impending recurrent pterygia. Twenty-three eyes of 23 patients who developed impending recurrence after pterygium surgery with conjunctival autografting and were treated with subconjunctival bevacizumab injection(s) (2.5 mg/0.1 mL) were included in the study. Anterior segment photographs were taken prior to and at 1 week, 1, 3 and 6 months after the injection, and at the end of the follow-up period. Image analysis was performed using an image processing and analysis software program. Recurrence rate and complications were recorded. The mean age and follow-up time of the patients were 51.2 +/- A 6.2 (31-60 years) and 16.8 +/- A 3.1 (12-22 months), respectively. The average number of injections was 2 +/- A 0.78 (1-3). Sixteen eyes required re-injection (two injections in nine eyes, three injections in seven eyes), due to progression of vascularization. There were significant differences between size percentage of lesions before injection and at 1 week, 1, 3 and 6 months after the injection (p < 0.05 for all). Corneal recurrence developed in only one patient and no ocular or systemic side-effects of bevacizumab were observed. Repeated injections of bevacizumab may help to prevent the high recurrence rate of residual impending pterygium, due to its adjuvant role in decreasing lesion size, especially in the first year after surgery.

    Does Topical Bevacizumab Prevent Postoperative Recurrence After Pterygium Surgery with Conjunctival Autografting?
    (2014) Karalezli, Aylin; Kucukerdonmez, Cem; Akova, Yonca A.; Koktekir, Bengu Ekinci; 24967201
    AIM: To assess the effect of topical bevacizumab use on postoperative pterygium recurrence in eyes who underwent pterygium excision with limbal -conjunctival autograft transplantation (LCAT). METHODS: eighty -eight eyes of 88 patients with primary pterygium were included. Pterygia were graded preoperatively from type 1 to type 3 (type 1 atrophic, type 3 inflamed) according to the inflammatory status. The eyes were preoperatively randomized to receive topical steroid and antibiotic treatment (group 1, 46 eyes) and additional topical bevacizumab (5 mg/mL; group 2, 42 eyes) in the postoperative period. All eyes underwent pterygium excision and LCAT. Medications were tapered and discontinued at one month. Postoperative complications and recurrence rates were recorded. RESULTS: The mean follow -up duration was 29.3 +/- 4.2mo (24-52mo) and 28.5 +/- 3.4 (24-48mo) in group 1 and 2, respectively (P>0.05). There were no statistically significant differences regarding the age or gender between groups (P>0.05). Also, the difference between groups with respect to pterygium type was not significant. During the follow -up period, recurrence developed in 2 eyes (4.3%) in group 1, whereas in one eye (2.4%) in group 2. No statistically significant difference between groups was found in recurrence rates (P>0.05). No re-operation for recurrence was necessary during the follow-up period in both groups. CONCLUSION: Topical bevacizumab seems to have no additonal effect on pterygium recurrence after LCAT.
