Purpose: To compare the recurrence rate of primary pterygium surgery after the adjuvant use of Beta radiation, Mitomycin C, and conjunctival autograft. Methods: 180 eyes of 180 patients were included in the study. All cases had primary pterygium excision following the use of adjuvant therapy of Beta radiation or Mitomycin C (0.02% for 5 minutes) or conjunctival autograft. The study was conducted at Fayoum University Hospital, Fayoum, Egypt, and Misr University Hospital. The patients were randomly divided into three groups, with each group comprising 60 patients. Group (A) included patients treated with Beta radiation following Pterygium excision, group (B) patients had primary pterygium excision with the application of 0.02% Mitomycin C for 5 minutes, and group (C) patients had conjunctival autograft to cover the bare area after pterygium excision. Patients were followed up for three years postoperatively. Results: group A had the highest recurrence rate (33.3%) followed by group B (13.3%), and finally group C presented a recurrence rate of 6.7%. Group B showed the highest rate of intra-ocular postoperative complications, while no intra-ocular complications were recorded in group C. Common complications in groups A and B were scleral melting, keratitis, and Dellen formation. Conclusion: Using conjunctival autograft after primary pterygium excision gives the best results regarding the rate of recurrence and postoperative complications. Meanwhile, B-radiation or Mitomycin C did not prove to be as good.

Purpose. The study aims to compare the long-term outcome of conjunctival autograft (CAU) and mitomycin C (MMC) in double-head pterygium surgery.Methods. This is a follow-up study of a comparative interventional trial. Thirty-nine eyes of the 36 patients with double-head pterygium excision in the original study 12 years ago were recruited for clinical assessment. Seven out of the 36 patients were lost. In the original study, each eye with double-head pterygium was randomized to have pterygium excision with CAU on one “head” (temporal or nasal) and MMC on the other “head.” All patients were invited for clinical assessment for conjunctival bed status and the presence of pterygium recurrence in the current study.Results. There was no significant difference between the size, morphology, and type of pterygium among the two treatment groups. The recurrence rate of CAU group and MMC group 12 years after excision was 6.3% and 28.1%, respectively (P=0.020). Among eyes without recurrence, the conjunctival bed was graded higher in the MMC group than the CAU group (P=0.024).Conclusion. The use of conjunctival autograft has a significantly lower long-term recurrence rate than mitomycin C in double-head pterygium surgery.

Introduction: Recurrence is the most common problem with pterygium excision. Various adjunctive methods have been described to decrease the recurrence rate of pterygium. Mitomycin C (MMC) and limbal Conjunctival Autograft (CAG) are most commonly used methods to reduce its recurrence. Aim: To compare the recurrence rate of pterygium and the complications with MMC eyedrops after bare sclera pterygium excision versus sutureless and glue free CAG. Materials and Methods: Total 104 eyes were divided into two groups (A and B) of 52 eyes each. Group A patients underwent bare sclera excision of pterygium followed by 0.01% MMC eye drops BD (twice a day) for five days and Group B patients had sutureless and glue free CAG using oozing blood as tissue adhesive after pterygium excision. The patients were followed-up postoperatively on day 1, day 3, day 7, one month, three months, six months and one year. All the patients were examined for recurrence and complications. Statistical analysis was done by using Statistical Package for the Social Sciences (SPSS) version 16 and student’s t-test was applied for comparison. Results: A total of 104 eyes of 92 patients were divided into two groups (A and B) of 52 each. The mean age of Group A was around 45 year and group B was around 43 years and the difference was statistically insignificant (p>0.05). Total three patients had recurrence in one year of follow-up in group A, out of which first case appeared before the end of 1st month, second before the completion of 3rd month and the third case at the last follow-up. In group B only one case presented with recurrence at 6th month follow-up. The difference between the recurrences in both the groups was statistically insignificant (p>0.05). Short term complications were observed in five patients in group A. One patient had corneal thinning; one had scleral thinning, two patients presented with avascular sclera and one patient with granuloma. In group B, 18 patients with graft retraction, eight with graft oedema, five with sub-conjunctival graft haemorrhage and one with granuloma were observed. All these complications resolved by the time. Long term complications were not observed in any patient of both the groups. Conclusion: This study concluded that the use of MMC eye drops (0.01%) BD or glue free and sutureless CAG after pterygium excision is safe and effective treatment modalities for pterygium.

Objective. This study aims to determine recurrence and complication rates among patients who underwent threecurrent pterygium treatment techniques: preoperative subpterygeal injection of mitomycin C, intraoperativeapplication of mitomycin with pterygium excision and pterygium excision with conjunctival autograft. Methods. This is a randomized controlled clinical trial in a tertiary hospital. We included patients with diagnosedprimary pterygium and who underwent either: A = pre-operative injection of 0.02% mitomycin C one month prior topterygium excision; B = pterygium excision with intraoperative mitomycin C application; or C = pterygium excisionwith conjunctival autograft. Results. We included 111 patients: a total of 120 eyes randomized to 3 groups (A, B, C) at 40 eyes per group.After 24 months of follow-up, there was no significant difference in the recurrence rates among the groups (6/40[15%] in groups A and B and 2/40 cases [5%] in group C; P=0.29). No complications were noted in groups B and C,while 1 case of scleral thinning was noted in group A. There was no significant difference in the complication ratesamong the three procedures (P=1.00). Conclusion. There were no significant differences in the recurrence and complication rates among the three techniques. Careful patient selection and follow-up are recommended to prevent complications such as scleral thinning.

Surgery is the only effective treatment for pterygium. The most common technique is the use of a conjunctival autograft after excision of the pterygium. However, the frequency of recurrences of this method, as well as possible complications in different sources, are different. Purpose. To evaluate the efficacy, safety and recurrence rate of conjunctival autograft after pterygium excision. Material and methods. 101 patients with pterygium. aged 57.31 ± 14.7 years. The follow-up period was 1 year in 56 patients and 2 years in 45 patients. All patients underwent excision of the pterygium with conjunctival autograft. Results. An intraoperative complication can be attributed to the insufficient area of the autoconjunctival graft during its transfer to the sclera, which occurred in three patients. Postoperative complications: graft edema in 14 cases (13.86%), granuloma in the suture area was observed in 1 case (0.99%). Recurrence of pterygium was noted in only three cases (2.97%). Conclusion. The use of a conjunctival autograft in pterygium surgery has shown its effectiveness and safety, as well as a low recurrence rate. The donor zone in the upper and lateral makes it possible to excise a sufficient area of autoconjunctival graft with preservation of the intact area of possible future surgery for glaucoma. Key words: conjunctival autograft, pterygium, recurrence of pterygium.

Abstract Background The main complication of primary pterygium surgery is the recurrence of the pterygium. In the present study, we aimed to compare a classical technique and facilitated tenon-free conjunctival autograft preparation and a limited tenon removal technique in pterygium surgery in terms of recurrence rate, complications, and operation duration. Material and Methods This is a retrospective, comparative, observational study. Group 1 comprised 120 eyes of 115 patients who underwent pterygium excision with a new facilitated tenon-free conjunctival-limbal autograft preparation and limited tenon removal technique between May 2017 and October 2019. Group 2 comprised 117 eyes of 113 patients who underwent pterygium excision with a conventional conjunctival-limbal autograft technique between January 2016 and May 2017. Results The mean follow-up time after surgery was 18.2 ± 5.8 months in group 1 and 19.1 ± 6.3 months in group 2 (p = 0.25). The mean operation duration was 5.54 ± 1.22 (4 – 7) minutes in group 1 and 8.23 ± 1.26 (8 – 10) minutes in group 2 (p = 0.02). Flap edema was present in 33 eyes (28.2%) in group 2 and in 11 eyes (9.16%) in group 1. Flap edema was significantly higher in group 2 (p < 0.001). At the end of the 1-year follow-up of the patients, we observed recurrence in only one (0.83%) eye in group 1 and 14 (11.96%) eyes in group 2. The recurrence rate of group 1 was significantly less than that of group 2 (p < 0.001). Conclusions The simplified technique of tenon-free conjunctival autograft preparation and limited tenon removal yielded better clinical outcomes without serious complications. Additionally, this technique shortened the surgical time and reduced surgeon-dependent factors.

Purpose: To find the outcome of autologous limbal conjunctival transplantation in terms of recurrence rate, as the main outcome measure and complications as the secondary outcome. Methods: The present study retrospective study conducted from a tertiary eye care hospital. Pterygium excision with limbal conjunctival autograft from the affected eye was performed for primary pterygium. Secondary pterygia resulting from inflammation, trauma and other diseases were excluded. Patients were followed up for 18 months for recurrence and other complications. Results: A total of 36 eyes of 36 patients with primary pterygia from November 2016 and October 2017 were included in the study. The study recruited 19 (52.7%) males and 17 (47.2%) females with mean age of 38.2 ±10.42 years. Pterygium was diagnosed more commonly in left eye(55.5%)  as compare to right eye(44.4%). Out of 36 cases 32 (88.8%) cases of  nasal and 4 (11.1%) cases of temporal pterygium noted. Out of 36 cases Graft edema in 1 (2.7%) case, graft retraction in 2 (5.5%) cases and 1 (2.7%) case of granuloma were noted. Any kind of pterygium recurrence and graft necrosis was not noted in present study. Conclusions: Pterygium excision with autologous limbal conjunctival autograft is safe and effective method to treat primary pterygium.
