Abstract
AIM To evaluate the cosmetic surgical outcomes of primary corneal pterygia excision using the avulsion (snatching) technique. METHODS A prospective, interventional study included twenty-five eyes of 25 patients with primary pterygium underwent excision were followed up for at least 6 months. In all patients, snatching (modified avulsion) technique was utilised to avulse the pterygium head off the corneal surface and remove any residual fibres by Colibri without need for keratectomy with a scalpel. RESULTS The study involved 25 eyes of 25 patients with an average age of 42.5±56.5 years. The mean follow-up was 6 months. One-week post-op, 8 patients (32%) reported they can tell which is the operated eye but looked untouched while 17 (68%) patients reported that the operated eye looked red but is accepted. Twenty patients (80%) reported some discomfort while the remaining 5 patients (20%) reported no discomfort. Cornea examination showed a clear cornea in 18 eyes (72%), 6 eyes (24%) had mild keratitis, and 1 eye (4%) had clouding at the surgical site. Over an average of six months post-op follow-up period, all the patients (100%) reported they cannot tell which eye had the surgery and none (0%) of them reported discomfort. Examination of the cornea was clear in 24 (96%) eyes, but 1 (4%) eye had mild keratitis. CONCLUSION Snatching (modified avulsion) technique was found to be effective, safe, and presents decent aesthetic appearance for the management of primary corneal pterygia when safety points are firmly followed.

Abstract
INTRODUCTION The purpose of this study is to compare the "real-life" effectiveness of amniotic membrane graft (AMG) and conjunctival (CAT) or limbal conjunctival (LCA) autograft in the management of primary pterygium. METHODS Human-based studies on primary pterygium surgery that were published between 1993 and 2022 with at least 3 months of follow-up were identified, and only those that were retrospective were included. The global recurrence rate of pterygium was assessed for each surgical technique separately. Specific recurrence rates taking into consideration the fixation technique (glue versus sutures) were also measured. RESULTS 35 real-life retrospective subgroups comprising a total of 3747 eyes were included in the final review. The mean global recurrence rates for CAT, LCA and AMG were 7.61%, 5.50% and 9.0%, respectively. Recurrences were less common for patients who received fibrin glue (5.92%, 2.56% and 3.60%) than for those who received sutures (8.99%, 6.03% and 23.0%) for the three groups, respectively. Surgical techniques combining CAT or LCA with AMG yielded an even lower global recurrence rate (1.83%). CONCLUSION AMG seems like a reasonable option that could be considered in primary pterygium surgery, especially when glued to the underlying sclera. Combining AMG with other treatment modalities such as CAT or LCA seems to offer an interesting alternative in terms of recurrence.

Abstract
Background To demonstrate the long-term results of enhanced cosmetic pterygium surgery with extensive Tenonectomy, adjunctive fibrin-glued amniotic membrane transplantation (AMT), and mitomycin C (MMC). Methods Retrospective chart review of patients who had pterygium surgery with AMT and MMC between January 2001 to July 2017 and had completed at least 6 months of follow-up. Early and long-term postoperative cosmetic outcomes, recurrence rate, and complications were analyzed. Cosmetic outcomes were evaluated based on patient and surgeon reported outcome measures. Results The study was conducted on a total of 603 eyes of 578 patients (316 males, 262 females) with an average age of 52.9 ± 15.1 years. At post-op day 1, patients reported no discomfort and could not tell which eye had surgery based on patient reported subjective grading scales. Over an average follow-up period of 23.1 ± 35 months (range: 6–216 months), there was one pterygium recurrence (0.2%), eighteen granulomas (2.9%), one self-resolving scleral melt (0.2%), one correctable restricted ocular motility (0.2%), one pupil abnormality (0.2%), one dellen (0.2%) and one correctable upper lid abnormality (0.2%). Planned laser vision correction was used for residual corneal scar in eleven eyes (1.8%) as a staged refractive approach. Conclusion This study highlights an improved technique of an old concept of pterygium surgery that not only reduces the recurrence but also enhances cosmetic excellence and improves the quality of vision.

Abstract
Objective: To evaluate the recurrence rate and outcome of pterygium surgery with amniotic membrane transplantation (AMT) and intraoperative mitomycin C (MMC). Methods: This prospective clinical study included patients with pterygium who were candidates for pterygium excision. After the surgical excision, intraoperative local MMC were applied in the standard protocol followed by AMT. The outcome measures were recurrence and the size change of lesion. Kaplan-Meier estimation and regression analyses were performed. Findings: Fifty five eyes of 55 consecutive patients including 30 male (54.5%) and 25 female (45.5%) with mean age of 47.12 ± 15.95 years were operated. The mean follow-up period was 15.21 ± 2.67 months. The overall recurrence rate was 34.5% (19/55 cases). The estimated recurrence time for larger size of pterygium before surgery was short and marginally significant (17.14 ± 0.58 month in size of ≤3.0 mm versus. 18.56 ± 0.60 month in size of <3 mm; P= 0.06). A statistically significant association was found in reduced model among the size change of the pterygium and standardized coefficient was −0.012 (P = 0.044) and −0.743 (P < 0.001) for age and size of lesion before surgery, respectively. Conclusion: Our findings suggest that increasing age and pterygial tissue are the risk factors for recurrence and pterygium has a substantial recurrence rate even after AMT combined with MMC.

Abstract
BACKGROUND In our study we describe a method that optimizes size of excision and autografting for primary pterygia along with the use of intraoperative MMC and fibrin glue. Our objective is to propose a simple, optimizedpterygium surgical technique with excellent aesthetic outcomes and low rates of recurrence and otheradverse events. METHODS Retrospective chart review of 78 consecutive patients with stage III primary pterygia who underwent an optimal excision technique by three experienced surgeons. The technique consisted of removal of the pterygium head, excision of the pterygium body and Tenon's layer limited in proportion to the length of the head, application of intraoperative mitomycin C to the defect, harvest of superior bulbar limbal conjunctival graft, adherence of graft with fibrin glue. Outcomes included operative time, follow up period, pterygium recurrence, occurrences of incorrectly sized grafts, and other complications. RESULTS All patients were followed up for more than a year. Of the 78 patients, there were 2 cases of pterygium recurrence (2.6%). There was one case of wound dehiscence secondary to small-sized donor conjunctivaand one case of over-sized donor conjunctiva, neither of which required surgical correction. There were no toxic complications associated with the use of mitomycin C. CONCLUSION Correlating the excision of the pterygium body and underlying Tenon's layer to the length of the pterygium head, along with the use intraoperative mitomycin C, limbal conjunctival autografting, and fibrin adhesionresulted in excellent outcomes with a low rate of recurrence for primary pterygia.

Abstract
PURPOSE To determine the risk factors related to recurrence of pterygium after pterygium excision with limbal-conjunctival autograft. STUDY DESIGN Retrospective, observational case series. METHODS The current study included 310 patients who underwent surgical removal of pterygium using limbal-conjunctival autografting. All surgery was performed by the same surgeon at a single Hospital from 2006 to 2011. Preoperative and postoperative patient data were collected. The patients were summoned to follow-up examinations. Procedures with at least 12 months of follow-up were included in the final analysis. Potential risk factors for pterygium recurrence were determined by Cox proportional-hazard linear analysis and recurrence-free survival time was evaluated using Kaplan-Meier method. RESULTS The overall recurrence rate was 5.2% during an average follow-up time of 20.1±8.6 months (range, 12-37 months). According to Kaplan-Meier evaluation, the estimated time to recurrence was 34.2 ± 0.5 months (95% confidence interval 33.3-35.0 months) for the whole population. Multivariate analysis showed that age < 45 years old (RR = 3.582, 95% CI 1.984-13.044, P = 0.047), recurrent type of pterygia (RR = 4.856, 95% CI 1.794-13.142, P = 0.002), and vertical size of pterygium > 6.7 mm (RR = 2.529, 95% CI 1.053-6.075, P = 0.038) were significantly associated with increased risk of recurrence. CONCLUSION Our findings suggest that young age, recurrent type of pterygia, and larger pterygial tissue are risk factors for pterygium recurrence after surgical excision. Hence, early excision of pterygium is recommended to decrease the recurrence rate.

Abstract
OBJECTIVE The purpose of this study was to evaluate the efficacy of sequential pterygium excision with conjunctival autograft (PECA) in the management of double-headed pterygia. METHODS All patients who underwent a sequential PECA procedure for double-headed pterygia from 2004 to 2009 were included in this retrospective, noncomparative, interventional case series. The recurrence rate and visual outcomes after this procedure were determined. RESULTS Nine eyes of 8 patients with doubled-headed pterygia undergoing sequential PECA were identified. Of 18 PECA procedures, 1 recurrence (5.56%) was found. The single recurrence was observed nasally in the right eye (first site operated) of a female patient 55 months after the second PECA procedure. None of the operated eyes lost any lines of corrected distance visual acuity, and 22% gained at least 1 line of corrected distance visual acuity. CONCLUSIONS In this series, harvesting the conjunctival autograft from the same site several months later does not appear to increase the rate of recurrence. Sequential PECA is a safe and effective method of addressing double-headed pterygia.

Abstract
PURPOSE To compare the outcomes of superior versus inferior conjunctival autograft (CAU) in the prevention of recurrence after performing a pterygium surgery in patients with primary pterygia. METHODS This was a prospective randomized study of 60 eyes of 60 patients with primary pterygium. All the eyes underwent pterygium excision and were assigned randomly to receive either superior (30 eyes) or inferior (30 eyes) CAU. All grafts were attached with fibrin glue. The patients were followed up on postoperative day 1, day 7, 1 month, 3 months, and 6 months. RESULTS Outcome measures included rate of recurrence, mean surgical time, visual analog scale pain score, and amount of pain medication required in the first postoperative week. The mean surgical time, visual analog scale pain score, and amount of pain medication required in both groups were not statistically different. A follow-up of at least 6 months (mean 5.5 ± 1.1 months) was achieved in 49 eyes of 49 patients (24 eyes in the superior CAU group and 25 eyes in the inferior CAU group). One eye in the superior CAU group (4.2%) and 1 eye in the inferior CAU group (4.0%) developed pterygium recurrence. There was no statistically significant difference in the recurrence rates between the 2 groups. In the inferior CAU group, mild localized donor site scarring was noted in 2 patients (8.3%). CONCLUSIONS Pterygium excision with superior or inferior CAU secured with fibrin glue is safe and effective. There was no significant difference in surgical time, pain, and recurrence rates of pterygium after excision with superior or inferior CAU.

Abstract
Background: Inferior limbal-conjunctival autograft transplantation has been described as a safe and effective treatment for primary pterygium. However, despite its multiple advantages, routine performance of this technique is difficult because the inferior conjunctiva is often too small to provide enough autograft material. To resolve this issue, we modified a technique, inferior separate limbal-conjunctival autograft transplantation, and evaluated its efficacy and safety Materials and Methods: A total of 50 eyes of 47 patients were retrospectively studied. Our surgery consisted of a thorough pterygium excision followed by 0.02% mitomycin C application. Next, we performed inferior conjunctival autografting, in which limbal and bulbar conjunctival autografts were independently harvested and secured to the denuded limbus and the most posterior conjunctival defect at the pterygium excision site to ensure stem-cell restoration and deep fornix reconstruction, respectively; the bare sclera between the two grafts was exposed. The outcome was assessed with a three-point grading scale at the patient's last visit. Results: The success and recurrence rates were 96.0% (48 of 50) and 0%, respectively, assessed at follow-ups occurring at a mean of 19.2 ± 5.6 months after surgery. Only minimal complications were encountered. Conclusion: A combination of inferior separate limbal-conjunctival autograft transplantation with intraoperative 0.02% mitomycin C application is a safe and effective technique enabling the routine use of under-sized autografts harvested from the inferior conjunctiva after thorough pterygium excision.

Abstract
PURPOSE To compare the outcomes of free conjunctival autograft (CAU) versus conjunctival-limbal autograft (CLAU) in the prevention of recurrence after pterygium surgery with adjunctive mitomycin C application in patients with primary or recurrent pterygia. DESIGN Prospective, randomized study. PARTICIPANTS AND CONTROLS Eighty-seven eyes of 86 patients with primary or recurrent nasal pterygia were included. METHODS All eyes underwent pterygium excision followed by removal of subconjunctival fibrovascular tissue and application of 0.02% mitomycin C for 3 minutes. The eyes then were assigned randomly to receive either CAU (44 eyes) or CLAU (43 eyes). MAIN OUTCOME MEASURES Rate of conjunctival or corneal recurrence of pterygium after surgery. RESULTS A follow-up of at least 12 months (mean, 14 ± 2.2 months) was achieved in 78 eyes of 78 patients, including 39 eyes in the CAU group (31 primary and 8 recurrent pterygia) and 39 eyes in the CLAU group (33 primary and 6 recurrent pterygia). After surgery, no eye in the CLAU group developed pterygium recurrence; however, recurrence was seen in 2 eyes (5.1%) in the CAU group, including 1 of 31 patients (3.2%) with primary pterygia and 1 of 8 patients (12.5%) with recurrent pterygia. There was no statistically significant difference in recurrence rates between the 2 groups or in the primary and recurrent subgroups. In the CLAU group, a localized pannus formation at the donor site of the limbal graft was noted in 5 eyes (12.8%), with the appearance of pseudopterygium in 1 eye. CONCLUSIONS There was no significant difference in recurrence rates of pterygium after surgery with mitomycin C application between the CAU and CLAU groups, more remarkably in primary cases. Limbal damage was seen in some eyes with CLAU.

Abstract
PURPOSE To evaluate clinical outcome(s) and complication(s) of topical bevacizumab (avastin) in patients with impending recurrent pterygium. PATIENTS AND METHODS This prospective clinical trial included 54 consecutive patients (54 eyes), who underwent pterygium surgery with bare sclera and mitomycin, and who were diagnosed with impending recurrent pterygium. Of the 54 patients, 26 received eye drops containing bevacizumab (5 mg/ml) twice a day and betamethasone four times daily for 1 week. In the other 28 patients, betamethasone alone was administered four times daily for 1 week. Follow-up times were 3-6 mos. RESULTS All patients in both groups failed, i.e., fibrovascular tissue (pterygia) eventually extended onto the cornea. However, in patients receiving topical bevacizumab, the mean progression of fibrovascular tissue extension during the first week, first month, and third month of follow-up was significantly less than that in the control group (p < 0.01). The mean duration for invasion of cornea in study group patients was significantly longer than that for control group patients (p < 0.01). CONCLUSION Short-term use of topical bevacizumab seems to be a safe and effective means for delaying recurrence of impending recurrent pterygia.
