“…This finding is in contrast to the studies in [8,9], whereby the authors concluded that systemic factors will not induce the pterygium condition. Besides the above, another study [13] from Gambella, Ethiopia agreed with the previously observed major risk factors, such as exposure to sunlight and outdoor activities. However, they also found that males have greater risk of being affected by pterygium compared to females, which supports the findings of Cahjucom-Uy et al [12].…”

Pterygium is an eye condition that causes the fibrovascular tissues to grow towards the corneal region. At the early stage, it is not a harmful condition, except for slight discomfort for the patients. However, it will start to affect the eyesight of the patient once the tissues encroach towards the corneal region, with a more serious impact if it has grown into the pupil region. Therefore, this condition needs to be identified as early as possible to halt its growth, with the use of simple eye drops and sunglasses. One of the associated risk factors for this condition is a low educational level, which explains the reason that the majority of the patients are not aware of this condition. Hence, it is important to develop an automated pterygium screening system based on simple imaging modalities such as a mobile phone camera so that it can be assessed by many people. During the early stage of automated pterygium screening system development, conventional machine learning techniques such as support vector machines and artificial neural networks are the de facto algorithms to detect the presence of pterygium tissues. However, with the arrival of the deep learning era, coupled with the availability of large training data, deep learning networks have replaced the conventional networks in screening for the pterygium condition. The deep learning networks have been successfully implemented for three major purposes, which are to classify an image regarding whether there is the presence of pterygium tissues or not, to localize the lesion tissues through object detection methodology, and to semantically segment the lesion tissues at the pixel level. This review paper summarizes the type, severity, risk factors, and existing state-of-the-art technology in automated pterygium screening systems. A few available datasets are also discussed in this paper for both classification and segmentation tasks. In conclusion, a computer-assisted pterygium screening system will benefit many people all over the world, especially in alerting them to the possibility of having this condition so that preventive actions can be advised at an early stage.

Abstract. Pterygium is an overgrowth of fibrovascular tissue of the nasal conjunctiva. The p revalence in the world is 10.2%. The aim of the study was to describe the characteristics of pterygium in patients at Al Ihsan Hospital in 2016-2021. This research was a descriptive observational study using medical records. The research subjects were selected by purposive sampling supporting 959 people. The results of 40-year-old pterygium sufferers 40-50 years, namely 243(25.3%), women, namely 713(74.4%), housewives, namely 593(61.8%), in rural areas, namely 937(97.7%), not attending school, namely 364 ( 37.9%), had no family history, namely 861(89.8%), did not smoke, namely 627(65.4%), comorbid hypertension, namely 574(40.2%), pterygium stage 2, namely 446(46,6%), clinical symptoms of red eye was 506(52.8%),medical management was 620(64.7%), had no recurrence was 869(90.6%), in the right eye was 358(37.3%),the religion of Islam is 956 (99.7%). It was concluded that pterygium occurs mostly in women aged 40-50 years, housewives, in rural areas who do not attend school, are Muslim, have no family history, do not smoke, with comorbid hypertension, suffer from stage 2 pterygium, in the right eye with clinical symptoms of red eyes, recurrence and medical management. Abstrak. Pterygium merupakan pertumbuhan berlebih jaringan fibrovascular nasal konjungtiva. Prevalensi di dunia 10,2%. Tujuan penelitian untuk mengetahui gambaran karakteristik pterygium pada pasien di RSUD Al Ihsan tahun 2016-2021.Penelitian ini deskriptif observasional menggunakan rekam medis.Subjek penelitian dipilih dengan purposive sampling berjumlah 959 orang. Hasil didapatkan mayoritas penderita pterygium berusia 40-50 tahun yaitu 243(25,3%), perempuan yaitu 713(74,4%), ibu rumah tangga yaitu 593(61,8%), di perdesaan yaitu 937(97,7%), tidak sekolah yaitu 364(37,9%), tidak memiliki riwayat keluarga yaitu 861(89,8%), tidak merokok yaitu 627(65,4%), komorbid hipertensi yaitu 574(40,2%), pterygium stage 2 yaitu 446(46,6%), gejala klinis mata merah yaitu 506(52,8%), penatalaksanaan medis yaitu 620(64,7%),tidak memiliki rekurensi yaitu 869(90,6%), pada mata kanan yaitu 358(37,3%), beragama Islam yaitu 956(99,7%). Disimpulkan pterygium banyak terjadi pada perempuan 40-50 tahun, ibu rumah tangga, di perdesaan yang tidak bersekolah, beragama Islam , tidak memiliki riwayat keluarga, tidak merokok, dengan komorbid hipertensi, menderita pterygium stage 2, di mata kanan dengan gejala klinis mata merah, rekurensi dan penatalaksanaan manajemen medis.

“…8 In addition to cosmetic problems, pterygium can lead to eye irritation, disrupt the transparency of the pupil area, and cause disorders such as corneal astigmatism; in addition, it may rarely lead to visual impairment due to damage to the visual axis, which in severe cases requires surgery. 6,[9][10][11] Due to the importance of this disease, this review provides a major review on etiologies, risk factors, complications, and surgical management of pterygium, focusing on the updates and the new features of the literature. Since new methods and medications are constantly developed to further reduce the recurrence of the pterygium after excision, different methods of pterygium surgery and recent adjuvant therapies are discussed in this review article.…”

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.
