“…Our study had a mean astigmatism of 2.135 ± 1.36 preoperatively in the inferior rotational group, which came down to 1.14 ± 0.99 at 1 month. In contrast to this, in the prospective multicenter study by Karadag et al [ 18 ] on 45 subjects who underwent rotational autograft, astigmatism decreased from 1.53 ± 1.31 to 1.04 ± 0.67 D by 1 month of surgery. This difference might be because the preoperative astigmatism was much higher in our study and most of the pterygia were of fleshy grade, whereas in their study, the preoperative astigmatism was lesser and most of the pterygia were of grade 2.…”

Purpose: To compare the outcomes of pterygium surgery by using an inferior rotational autograft and a conventional superior conjunctival autograft. Methods: This was a prospective interventional comparative study of 85 eyes of patients who were divided into two groups of 45 and 40. Standard techniques of both procedures were performed by a single surgeon. Astigmatism, recurrence rates, time taken, and other complications were compared. Results: All the subjects were in the age group 53 ± 7.56 (40–74) years. Demographic data and type of pterygium were comparable in the two groups. In the rotational group, the preoperative astigmatism was − 2.14 ± 1.36 D, which decreased in 1 week to 1.42 ± 1.11 D, in 1 month to − 1.13 ± 0.99 D, in 3 months to 0.91 ± 0.72 D, and in 6 months to 0.81 ± 0.85 D (P < 0.05 each). Preoperative astigmatism in the conventional group was − 2.63 ± 1.47 D, which decreased to − 1.43 ± 1.04 D in 1 week, −1.18 ± 0.85 D in 1 month, −1.07 ± 0.81 D in 3 months, and − 1.01 ± 0.78 D in 6 months (P < 0.05 each). There was no significant difference between the groups in terms of astigmatism at any follow-up visit (P < 0.05). Complications like dellen, graft edema, and superficial vascularization were seen in both groups. The rotational group had one recurrence (2.86%). No recurrence was noted in the conventional group. None of the complication rates was significantly different between the two groups (P < 0.05). Conclusion: Inferior rotational conjunctival autografting is a good technique for management of pterygium. It has a profile similar to that of conventional conjunctival autograft.

“…19,20 Although the pathogenesis of pterygium is not fully understood, it is believed that in the development of pterygium, corneal epithelial cells acquire an altered balance between proliferation and apoptosis. 21,22 The cellular origin of fibroblasts is not only remnants of embryonic origin but may arise from tissue-specific epithelial cells. 23 The phenomenon in which epithelial cells change their phenotype to fibroblastic cells following morphogenic pressure from damaged tissue is called Epithelial-Mesenchymal Transition (EMT), and it is a common feature of cancer cells.…”

Pterygium is a bulbar conjunctival fibrovascular growth that crosses the limbus and extends onto the peripheral cornea, and in some cases leads to significant visual complications. The prevalence of this disease has been reported to be from 1.2% to about 40% in different parts of the world. Although there are various risk factors for pterygium, which include ultraviolet (UV) radiation, viral infection, hereditary factors, immune factors, aseptic inflammation, and environmental irritation, the pathogenesis of pterygium is mainly related to exposure to UV light. In addition to cosmetic problems, pterygium can lead to eye irritation, disrupt the transparency of cornea on the pupil area, and cause disorders such as corneal astigmatism and damage to the visual axis leading to vision impairment. In the last few years, the treatment of pterygium has been developed and various new solutions have been used. Surgery is the main treatment for pterygium. Various techniques such as Bare Sclera, Rotational Conjunctival Flap, Limbal Conjunctival Autograft, Amniotic Membrane Graft, and Free Conjunctival Autograft are used for the removal of pterygium. It also seems that the worrisome problem of recurrence has been significantly reduced with newer treatment methods. On the contrary, the use of auxiliary treatments such as mitomycin C, b-radiation, 5-fluorouracil, topical use of interferons, and Avastin are also effective in reducing the recurrence rate.

A comparison of two conjunctival rotation autograft techniques in primary pterygium surgery

Abstract: BothCRA techniques can be successful in patients for whom it is desirable to avoid a conjunctival autograft and for patients without high cosmetic expectations.
