“…There was no recurrence in our study. It is comparable to those by Prabhakar et al [13], Bastola, [8] and Das et al [14] There was no recurrence in those study too, but the difference was that we used vicryl 8-0 suture while Prabhakar et a1. Beside longer surgical time, graft suturing also carries the risk of complications like granuloma formation, and discomfort with exposed suture ends after surgery, and if non-absorbable stitches are used there is the need for suture removal.…”

Introduction: Surgical removal is the treatment of choice for pterygium; however, prevention of recurrence is a challenge. Several techniques have been tried to reduce the ﬁbro-vascular activity aiming to reduce rate of recurrence such as B-irradiation, conjunctival and limbal auto-grafting, anti-mitotic drugs, and amniotic membrane transplantation. This study reports the magnitude of the disease in a hilly region of western Nepal and outcome of excision and conjunctival autografting for pterygium surgery. Methods: A prospective study was done from 1st July 2015 to 31st December 2016 in which all patients with primary pterygium presented to Palpa Lions Lacoul Eye Hospital from 1st July 2015 to 30th June 2016 were treated and followed up for next six months. Patients were treated medically or surgically as indicated. Data on age, sex, visual acuity, extent of disease, treatment modality, complications, and outcome were collected and analyzed by descriptive statistics, Chi-square test, t-test, and Anova tests. P value less than 0.05 was considered significant. Results: There were 18,960 patients in total attending hospital for various conditions among which 290 (1.5%) had pterygium. There were 186 (64.1%) female and 104 (35.9%) male and this difference was significant (p<0.001). The mean age was 47.42 yrs (SD=14.23) with age ranging from 20 to 80 years. Right eye was affected more (43.1%) than left eye (33.1%); remaining 23.8% had bilateral disease. Grade-1 disease occurred in younger age compared to Grade-2 and Grade-3 disease. All grade-1 patients were managed medically; grade-2 and grade-3 patients were equally likely to be managed medically or surgically. There were no major intra or post-operative complications. Minor post-operative complications noted were subconjunctival hemorrhage, corneal scarring, suture gaping, and conjunctival cyst among others. Conclusion: Despite much advanced techniques in pterygium surgery, pterygium excision combined with conjunctival autograft is found to be a safe and effective method for treating pterygium in developing world.

“…18,25 Similar observations were made both by Rohatgi S and Prabhakar SK who in their respective studies found that approximately 92% cases of pterygium belonged to nasal side. 5,20 In present study, progressive pterygium was present in 80% of patients whereas atrophic in 20% of patients. Similar observation was made by Chavan WM et al in their study where they found progressive pterygium in 72.4% eyes and atrophic in 27.6% eyes.…”

“…Prabhakar SK also concluded that males suffered more than females. 20 In this study, it was found that higher incidence of pterygium was in rural folk 66.67% who are exposed more to heat, dust, sun glare and atmospheric irritants. The tendency of prevalence of pterygium in rural area is more because of constant exposure of persons to more open and dusty environment in comparison to urban people.…”

Background: Pterygium is a fibrovascular wing or triangular shaped tissue that develops from the conjunctiva and encroaches on to the cornea.Methods: This prospective observational study was conducted at postgraduate department of Ophthalmology of GMC Jammu, Jammu and Kashmir, India. A total of 90 pterygium patients were selected to analyze various sociodemographic factors especially age, sex, residence, occupation, position etc. on the occurrence of this problem.Results: In the present study, out of 90 pterygium patients, 40% were in the age of 31-40 years followed by 24.44% in 41-50years, 60% were males whereas 66.67% belong to rural areas. The incidence was found to be maximum among farmers 35.56% followed by labourers 20%. The right eye was involved in 55.56% cases while majority 97.78% cases of pterygium were nasal. Progressive pterygium was found in 80% while 20% reported with atrophic pterygium.Conclusions: People who work outdoors are subjected to involuntary U.V. B exposure, dust. Workers must be aware of this and they must take appropriate precautions like wearing protective photochromatic glasses, caps etc.

“…Pterygium is horizontal, most frequently nasal, and grows across the limbus invading Bowman´s layer; whereas pseudopterygium can be located anywhere, most frequently in an oblique orientation, and is not adherent to the limbus [ 4 ]. Thus, to differentiate between a pseudopterygium and a pterygium, it is important to verify whether the conjunctival neoformation is really attached to the cornea [ 9 ]. Prabhakar et al [ 9 ].…”

“…It is known that pseudopterygium can be caused by corneal degenerations, such as marginal Terrien’s degeneration, or by corneal injuries, such as chemical or thermal burns [ 4 ]. However, there are other possible causes described in the literature, namely iatrogenic limbal damage, limbus auto-transplant, or chronic inflammation, among others ( Figure 2 ) [ 4 , 6 , 8 , 9 ]. It is important to distinguish pseudopterygium from true pterygium.…”

Pseudopterygium is a non-progressive conjunctival adhesion to the peripheral cornea secondary to a corneal-limbus damage. According to the literature, the main etiology is a previous eye trauma. Nevertheless, this could be biased by the existence of other underdiagnosed causes of pseudopterygium, some of which may have severe consequences for the integrity of the eye and patient’s life. This comprehensive literature review was performed based on a search on the PubMed and Google Scholar databases of relevant pseudopterygium published papers according to our current knowledge and seeks to gather the existing evidence about its diverse etiologies and clinical features, as well as to propose a diagnostic algorithm to simplify its correct approach.
