Background: Pterygium causes visual problems due to induced corneal astigmatism or direct encroachment onto the visual axis. The present study was conducted to compare preoperative and postoperative changes in corneal astigmatism after pterygium excision by different techniques. Subjects and Methods: The present study was conducted from May 2018 to August 20018 on 69 patients of age range 20-55 years of primary Pterygium. Patients were divided into three groups of 23 each. Group I was treated with bare sclera (BS) technique, Group II with conjunctival autograft (CAG) technique and Group III with amniotic membrane graft (AMG) technique. All the patients were preoperatively assessed for visual acuity, anterior and posterior segments, autorefraction, and autokeratometry. After surgery, the patients were recalled on day 5, 1 month, and 3 months for the analysis. Results: Uncorrected visual acuity (UCVA) preoperatively was 0.57, on the 5th day was 0.45 after 1 month was and after 3 months was 35. The mean preoperative astigmatism value in group I was 3.45, in group II was 3.52 and in group III was 3.49. Postoperative astigmatism value in group I was 1.60, in group II was 0.92 and in group III was 0.81. The difference was significant (P< 0.05). Conclusion: Authors found that amniotic membrane graft and a conjunctival autograft is better surgical techniques than bare sclera in reducing astigmatism.

Aims and objectives: To evaluate the postoperative symptomatic comfort, visual changes,complication and rate of recurrence in free conjunctival autograft and rotational flap technique inprimary pterygium surgery. Materials & Methods: This prospective study was conducted in 60 eyesof 60 patients, presented with primary progressive nasal pterygium larger than 1mm causingsymptomatic discomfort, astigmatism and cosmetic disfigurement. Patients were divided into twogroups randomly. In group A, patients with pterygium excision with free conjunctival autograft andgroup B, pterygium excision with rotation flap technique were included. Post-operative day 1symptomatic comfort (symptoms and signs), graft stability, corneal clarity and any complicationwere noted. Visual acuity (VA), auto-refracto keratometer measurements and detailedbiomicroscopic examinations, were performed preoperatively and postoperatively at 1month and 3months. Results: Most of the patients in our study were in the middle age group of 40-49 years(41.6%). Out of 60 patients, 35 were males (58.4%) and 25 were females (41.6%). Patients withoutdoor activities had a higher prevalence of pterygium (78.4%). The incidence of pterygium wasmore in the right eye (60%) than left eye (40%). Of the 60 patients, Grade I, II and III pterygiumwas 20%, 56.7% and 23.3% in group A and 16.7%, 63.3% and 20% in group B respectively. Themean symptomatic score was statistically significantly higher for group A for each factor (P<0.05).In the 3rd month, the overall patient’s satisfaction score was significantly higher in group B(P<0.05). Conclusion: Both surgical techniques were equally effective in terms of visual acuity,astigmatism and recurrence. The patient’s satisfaction score was significantly higher in the rotationflap technique group.

Background: A pterygium is a wing-shaped growth of conjunctiva and fibrovascular tissue on the superficial cornea. The pathogenesis of pterygia is strongly correlated with UV light exposure and environmental factors. The prevalence of pterygia increases steadily with proximity to the equator, and the condition is more common in men than women. It is well established fact that before entering the optical zone pterygium causes flattening of the cornea in horizontal meridian with the more normal side of the cornea usually temporally, resulting in with-the-rule astigmatism.Methods: The study included 80 patients of primary pterygium who underwent pterygium excision with conjunctival autograft adhered by autologous blood surgery. After performing routine ocular examination which includes visual acuity without and with pinhole and pre-operative keratomery was assessed by autokeratorefractometer. Repeat examination was performed after 6 weeks of surgery. Patients with recurrent pterygium, pseudo-pterygium, and history of previous ocular surgery were excluded.Results: The pre‑ and postoperative corneal astigmatism were compared after 6 weeks of surgery. The changes in corneal astigmatism were statistically significant p value <0.001. The preoperative mean corneal astigmatism of 3.41 D was reduced to 1.59 D (p value <0.001) 6 weeks after surgery, but maximum change in astigmatism was seen in Grade IV >Grade III >Grade II >Grade I.Conclusions: Primary pterygium of all grades treated with well accepted technique pterygium excision with conjunctival autograft with autologous blood gives promising results in terms of improvement in corneal astigmatism and hence visual acuity as well.

Introduction: There are numerous adjunctive measures described to reduce the recurrence rates after pterygium excision. Objective: To study the efficacy and complications of sutureless and glue free limbal conjunctival autograft for the management of primary pterygium over a period of one year. Materials and methods: A prospective interventional case series was carried out in 40 consecutive eyes with primary nasal pterygium requiring surgical excision. Pterygium excision with limbal conjunctival autografting without using glue or sutures was performed in all the patients followed by bandaging for 48 hours. The patients were followed up post operatively on 2nd day, 1 week, 6 weeks, 6 months and 12 months. They were examined for haemorrhage, wound gape, graft shrinkage, chemosis, graft dehiscence, recurrence or any other complication. Results: The mean age of the patients was 42.8 years (range 23-61), 75% of which were males. Total graft dehiscence occurred in 2 eyes (5%), graft retraction in 3 eyes (7.5%) and recurrence was seen in 1 eye (2.5%). At 6 weeks postoperatively, the gain in uncorrected visual acuity ranged from 0.18 to 0.5 log MAR in 7 eyes. No other complication was noted. Conclusions: Sutureless and glue free limbal conjunctival autografting following pterygium excision is a safe, effective and economical option for the management of primary pterygium.DOI: http://dx.doi.org/10.3126/nepjoph.v4i2.6537 Nepal J Ophthalmol 2012; 4 (2): 230-235

Introduction: Pterygium excision is a commonly encountered surgery with different methods being used. These procedures range from simple excision to use of grafts. Limbal conjunctival autograft is currently the most popular surgical procedure. The most common method of autograft fixation is suturing. But it has its own drawbacks like increased operating time, post-operative discomfort, inflammation, buttonholes, necrosis, giant papillary conjunctivitis, scarring, and granuloma formation. Glue is widely used due to many advantages like easy fixation of the graft, shorter operation time, and reduction in complications and post-operative discomfort but at the same time has some disadvantages also like high cost, the risk of transmission of infectionsand inactivation by iodine preparations. Purpose: In the following study, we describe a simple method of accomplishing conjunctival autograft adherence during pterygium surgery avoiding possible complications associated with the use of fibrin glue or sutures. Design: Prospective study. Method: We used conjunctival autograft, which was not sutured or glued to the scleral bed. The fibrin formed from the oozing blood was used to get the graft adhesion to the scleral bed. This study was approved by institutional review board, and written consent form was taken from each participant. Results: The suture-less and glue-free conjunctival autograft was found to have excellent results in terms of surgical outcome as well as post-operative recovery. In addition, risk of side effects related to sutures and glue was eliminated. Conclusion: Suture-less and glue-free conjunctival autograft is a new, easy, and cheaper technique for the management of pterygium.
