Penggunaan lensa kontak khususnya pada remaja semakin meningkat, baik untuk keperluan kosmetik maupun untuk memperbaiki kelainan refraksi. Namun, peningkatan ini tidak diikuti oleh perilaku yang baik sehingga rentan mengalami gangguan pada mata. Penelitian ini dilakukan untuk mengetahui profil pengguna lensa kontak pada pelajar Sekolah Menengah Atas di Kecamatan Denpasar Utara. Penelitian ini menggunakan metode deskriptif observasional dengan pendekatan cross sectional yang diikuti oleh 35 orang pelajar dengan riwayat penggunaan lensa kontak. Seluruh subjek penelitian mengisi kuesioner mengenai perilaku dalam penggunaan lensa kontak setelah mendapat persetujuan dari orang tua/wali. Diperoleh data yang menunjukkan bahwa populasi pelajar pengguna lensa kontak didominasi oleh perempuan (94.29%). Seluruh responden menggunakan jenis lensa kontak lunak dan sebagian besar responden menggunakan lensa kontak dengan alasan untuk memperbaiki kelainan refraksi (65.71%). Jadwal penggantian lensa kontak didominasi oleh jadwal penggantian bulanan (54.29%). Lebih dari setengah responden pada penelitian ini telah menggunakan lensa kontak selama ?6 bulan (54.29%) dan didominasi oleh durasi penggunaan <6 jam dalam sekali pemakaian (48.58%). Penelitian ini menunjukkan bahwa sebanyak 62.86% responden memiliki perilaku penggunaan lensa kontak yang termasuk dalam kategori cukup. Sebanyak 42.86% pelajar memiliki riwayat keluhan terkait penggunaan lensa kontak yang didominasi oleh keluhan mata berair (11.43%). Penelitian ini menunjukkan bahwa sebagian besar pelajar pengguna lensa kontak belum mengikuti standar penggunaan dan perawatan lensa kontak yang benar. Berdasarkan hasil penelitian ini, perlu adanya edukasi kepada pengguna lensa kontak untuk meningkatkan perilaku penggunaan dan perawatan lensa kontak yang baik sehingga mampu mengurangi keluhan dan komplikasi terkait penggunaan lensa kontak.

ABSTRAK Lensa kontak disebut sebagai metode aman dan umum digunakan untuk memperbaiki kelainan refraksi miopia, hiperopia, astigmatisme, dan presbiopia. Lensa kontak mengurangi sensitivitas permukaan mata sehingga produksi refleks film air mata berkurang. Penguapan yang meningkat disertai dengan penurunan produksi film air mata menyebabkan sebagian besar (50- 75%) pengguna lensa kontak mengalami penyakit mata kering. Penelitian ini bertujuan untuk mengetahui pengetahuan mahasiswa Fakultas Kedokteran Universitas Udayana yang menggunakan lensa kontak terhadap keluhan penyakit mata kering berdasarkan karakteristik pengguna lensa kontak (usia, jenis kelamin, kelainan refraksi, alasan penggunaan lensa kontak, jenis lensa kontak), pengetahuan tentang lensa kontak, dan keluhan penyakit mata kering. Penelitian ini bersifat deskriptif dengan pendekatan cross sectional menggunakan metode survei kuesioner.Dari total 49 siswa yang menjadi responden dalam penelitian ini, 35 orang (71,43%) memiliki pengetahuan dalam kategori baik dan 14 orang (28,57%) dalam kategori cukup, serta kategori pengetahuan baik. Kesimpulan yang bisa ditarik dalam penelitian ini adalah bahwasanya sebagian dari respondennya telah memahami dan dapat menerapkan petunjuk dalam perawatan maupun penggunaan lensa kontak secara benar sehingga keluhan penyakit mata kering juga jarang dirasakan. Kata kunci: lensa kontak, penyakit mata kering, mahasiswa

Introduction: RGP contact lenses are indicated for correcting refractive errors in cases of high myopia and irregular astigmatism due to changes in the corneal curvature. Case Report: A 30-year-old female came with complaints of redness, pain, glare, blurred vision, and yellow discharge and tearing on the left eye for 2 days, history of using Soft Contact Lens (SCL) since 10 years old due to myopia. Visual Acuity of the right eye (VOD) with glasses was 6/12 and VA of the left eye (VOS) was 1/300. The patient was diagnosed with left eye corneal ulcer and was given levofloxacin eye drops, hydroxypropyl methylcellulose eye drops, and vitamin C 1000 mg. The left eye's corneal ulcer healed after three days, but the scarring left the cornea's surface uneven.. Patients were advised to replace the contact lenses with RGP contact lenses. After the RGP fitting, the appropriate size was obtained in both eyes and the patient adapted well with VOD RGP 1.0 and VOS RGP 1.0 False. The patient felt helped by the RGP contact lens. Discussion: RGP was given because it helped reduce the bacterial infection risk. RGP has a higher oxygen transmissibility and maintains the cornea's curvature to become more regular. It can be utilized as an optical device to repair excessive myopia in addition to irregular astigmatism. Conclusion: RGP contact lens can be an option for irregular astigmatism after corneal ulcers due to the SCL use in patients with high myopia to provide good outcomes.

Background Diabetic retinopathy (DR) constitutes a primary cause of blindness across all age groups. Ophthalmologists examine fundus images (FI) to detect and classify stages of DR. Development of deep learning can help clinicians to attain a larger volume in screening and diagnosing diabetic retinopathy, thereby decreasing the burden of visual impairment caused by DR. This study aimed to classify DR using ensemble convolutional neural networks (CNN) architectures. Methods We used data from the Indian Diabetic Retinopathy Image Dataset which consist of typical diabetic retinopathy lesions at pixel level. The dataset contains typical diabetic retinopathy structures as well as normal retinal structures and is divided into three parts: segmentation, classification, and location. There are 516 original color fundus images in the classification used as training set (413 images) and testing set (103 images). We used ensemble CNN architectures to classify diabetic retinopathy as no DR, mild non-proliferative DR (NPDR), moderate NPDR, severe NPDR and proliferative DR (PDR) based on fundus image. Results In this study we successfully created a model with ensemble CNNs to detect DR based on fundus images with area-under-the-curve, sensitivity, and specificity of 0.88, 0.89, and 0.90, respectively, which is on par with the most modern methods. Conclusion Based on the results, this model performs quite well in early detection of diabetic retinopathy and can be used to develop a more accurate model for detecting and classifying diabetic retinopathy. This model can also be used in assisting mass screening at lower cost without reducing diagnostic effectiveness.

Background: Uncorrected refractive errors are a leading cause of preventable visual impairment in children worldwide, impacting academic and social development. The COVID-19 pandemic disrupted routine pediatric eye health services and altered children's lifestyles, creating an urgent need to re-evaluate the burden of these conditions. This study aimed to determine the prevalence and geographical distribution of refractive errors among elementary school children across six districts in Bali, Indonesia, during the post-pandemic period (2022–2023). Methods: A descriptive cross-sectional study was conducted using secondary data from the John Fawcett Foundation (JFF) school eye health screening program. The final analysis included 2,145 elementary school children (47.5% male, 52.5% female) from 13 schools across six districts in Bali, screened between January 2022 and December 2023. Visual acuity was measured using a Snellen chart, followed by non-cycloplegic autorefraction for all children failing the initial screening. Ametropia was defined based on established spherical equivalent and cylindrical thresholds. Prevalence was calculated for each district, and a Chi-square test was used to analyze the association with gender. Results: The overall prevalence of ametropia was 4.1% (88/2,145). Myopia was the most common refractive error, accounting for 58 cases (2.7% of all children), followed by astigmatism with 22 cases (1.0%) and hypermetropia with 8 cases (0.4%). Significant geographical disparities were observed, with prevalence rates ranging from a low of 1.8% in Tabanan district to a high of 6.9% in Denpasar district. The highest prevalence rates were found in the urban and semi-urban districts of Denpasar (6.9%) and Buleleng (6.3%). There was no statistically significant association between gender and the presence of refractive error (p=0.115). Conclusion: The post-pandemic prevalence of refractive errors in this large cohort of Balinese schoolchildren reveals a significant public health challenge defined by a sharp urban-rural divide. The concentration of refractive errors, primarily myopia, in urban centers like Denpasar points to the profound impact of environmental and lifestyle factors on visual development. This evidence provides a clear mandate for the strategic deployment of targeted pediatric eye care resources to the island's most affected communities, ensuring the early detection and management necessary to prevent lifelong visual impairment and secure the future well-being of Bali's next generation.

Background The prevalence of refractive errors is reported to be higher in children born preterm. Factors such as gestational age, birth weight, and retinopathy of prematurity status, have a significant impact on the refractive development in preterm infants. Prematurity and low birth weight affect the development of organ systems in infants, including the eyes. In addition to immature retinas, other eye conditions, such as refractive status, are also observed. This study aimed to determine the risk factors of refractive status, specifically refractive errors (spherical equivalent, astigmatism, and anisometropia) in premature infants at a tertiary hospital in Bali. MethodsA cross-sectional study was conducted involving 53 premature infants. This study collected samples from January to August 2023 at the Neonatal Intensive Care Unit of Prof. dr. IGNG Ngoerah General Hospital. Data regarding gender, gestational age, birth weight, retinal condition, spherical equivalent, and refractive disorders were collected. The relationship between risk factors and spherical equivalent, astigmatism, and anisometropia were analyzed using multiple regression analysis with statistical significance set at p<0.05. ResultsHypermetropia is the most common finding in premature infants, followed by myopia and astigmatism. The prevalence of myopia (9.4%) and astigmatism (5.7%) is also more common among newborns of gestational age ≤30 weeks (p=0.024). Chronological age was significantly associated with spherical equivalent (β=0.424; p=0.019). ConclusionIn premature infants, chronological age was the risk factor of spherical equivalent. Other risk factors were not associated with the prevalence of refractive errors among premature infants.

Introduction & ObjectivesRefractive disorders are the second most common cause of blindness at all ages after cataracts andare the leading cause of visual impairment in the world. The World The most common refractivedisorder in students especially in Asia is miopia. This study aims to determine the prevalence andcharacteristics of miopia in elementary school children in Badung Regency, Bali. MethodsThis research is an observational with analytic cross-sectional study approach. Data were collectedprospectively in children in four elementary schools in Badung, Bali. To assess the relationshipbetween sex, age, history of wearing glasses in parents and duration of near work activity withmyopia using chi-square. ResultsThe subjects were 1,067 students, consisting of 557 (52.2%) women and 510 (47.8%) men, the mostage was 9 years (19.1%), the average duration of near work activity was 83.79 ± 29, 46 hours/week,152 students (14.24%) with refractive disorders and bilateral myopia were the most refractivedisorders (65.8%). Of the 150 students with miopia, 60% were female students, aged at most 11years (28%), 90% of students had uncorrectedmiopia, 68% of parents of students without miopia,mean near work activity was 81,71±23,30 hours / week. No significant relationship was foundbetween sex and age and the prevalence of myopia. Significant relationship was found between theuse of glasses in parents and the length of close-up activity with myopia with PR=7.35 (95% CI:7.10-10.56) and PR=1.177 (95% CI 1.05-1.78). ConclusionThere are differences in the characteristics of miopia in primary school students between urban andremote areas and between developed and developing countries due to sociodemographicdifferences, level of education, type of activity, income and culture.
