Abstract

Background: Decrease in eye accommodation response is a result of eye growth in children with myopia. Less than normal accommodation response to near focus increased lag of accommodation which decreased image quality of the retina due to hyperopic defocus. If it left uncorrected over a prolonged period of time, it will activate feedback mechanism which ultimately increases progression of myopia. Objective: This study aims to determine the relationship between myopia and accommodation amplitude in junior high school students in Padang city. Methods: This was a cross-sectional study involved 384 students with myopia from four state junior high schools in Padang. Visual acuity was determined using Snellen Chart, and refractive error was diagnosed by autorefractometer. The amplitude of accommodation was measured by RAF rule (Zabby). Results: Based on the degree of myopia, we found 64.58% low myopia, 27.87% moderate myopia, and 7.55% high myopia. The mean amplitude of accommodation in low myopia was 13.73 ± 1.30 Diopters, moderate myopia 10.52 ± 1.26 Diopters, and high myopia 8.41 ± 0.60 Diopters. Significant decreased in amplitude of accommodation were found between low versus moderate myopia, low versus high myopia, also moderate versus high myopia. Conclusion: there is significant correlation between myopia and amplitude of accommodation (p <0,05), higher grades of myopia show decreasing amplitude of accommodation. Keywords:myopia, amplitude of accommodation, RAF rule.

Abstract

Introduction & Objectives : The prevalence of myopia has approximately doubled in the past three decades, with rates of 70–87% among populations of school children and young adults in Asia. Approaches to treating myopia include spectacles and Rigid Gas Permeable (RGP) contact lenses. RGP has become a new "preference" because it is more comfortable and provides a more aesthetic look. This study aims to determine which method is better for correcting visual acuity in myopia patients. Methods : This cross-sectional study analyzed the outcomes and exposures measured at the same time. The sample included myopia patients (based on spherical equivalent) who underwent RGP contact lens fitting in the refraction outpatient clinic of M Djamil Hospital from January 2021 to December 2022. The samples were selected based on inclusion and exclusion criteria. The collected data included gender, age, and best-corrected visual acuity using spectacles and RGP. Results : Forty-three patients were eligible as the sample in this study. Most of the subjects were women (62.8%), and the mean age was 23.58 years old. The median LogMAR for the RGP group was lower than the spectacles group (0.00:0.10 on both eyes). Statistical analyses found a significant visual acuity improvement in the RGP group compared to the spectacles group in both the right and left eyes (p = 0.014 and p = 0.005, respectively (p < 0.05)). Conclusion : The use of RGP provides significantly better visual acuity in correcting myopia than spectacles. Myopia is more frequently found in young women.

Abstract

Introduction & Objective : Rigid Gas Permeable (RGP) toric contact lenses are generally considered in patients with high astigmatism, while spherical RGP contact lenses are present as an alternative option that can be used and still provide optimal results in patients with high astigmatism. Methods : A cross-sectional study was conducted at DR M Djamil Hospital Padang in January 2021 to December 2022 period. Inclusion criteria were patients who went to the eye clinic at DR M. Djamil Hospital in January 2021 to December 2022 period, patients with high astigmatism ? -2.00 D underwent correction vision with spectacles and RGP spherical contact lenses. Results best correction visual acquity (BCVA) compared between spectacles and spherical RGP contact lenses. Samples must meet the inclusion and exclusion criteria. Data is collected and analyzed using statistical applications. Results : 49 patients with high astigmatism corrected with spectacles and contact lenses showed data distribution was 15 men (30.6%) and 34 women (69.4%). Most age in the age group 20-29 years 24 people (49%). BCVA with spectacles obtained a median of 0.18 and an RGP of 0.00 based on LogMar. Mann whitney test showed significant difference between BCVA wearing glasses and RGP spherical contact lenses with a value of p = 0.006 right eye p = 0.009 left eye (p <0.005) Conclusion : Spherical RGP contact lenses can still be used in patients with high astigmatism if we don’t have toric RGP trial. Spherical RGP contact lenses show better BCVA results than spectacles in high astigmatism patients.

Abstract

Background: Keratoconus is a non-inflammatory corneal ectatic disorder characterized by progressive corneal thinning and ectasia, leading to irregular astigmatism and visual impairment. Rigid gas permeable (RGP) contact lenses are often prescribed to manage keratoconus; however, improper use can lead to complications such as infectious keratitis. Case presentation: We present a case of a 25-year-old female with keratoconus who developed infectious keratitis after three months of RGP lens wear. The patient presented with ocular discomfort, pain, photophobia, and redness in the left eye. Clinical examination revealed conjunctival and ciliary injection, a paracentral corneal infiltrate, and decreased visual acuity. Corneal pachymetry confirmed bilateral corneal thinning. The patient was diagnosed with bilateral keratoconus, bilateral compound myopic astigmatism, and left-eye infectious keratitis. Treatment included discontinuation of RGP lens wear, topical antibiotic therapy, and artificial tears. After two weeks of treatment, the corneal infiltrate resolved, and the patient was allowed to resume RGP lens wear with strict adherence to hygiene protocols. Conclusion: This case underscores the importance of patient education and meticulous lens hygiene in preventing infectious keratitis and other complications associated with RGP lens wear in keratoconus patients. Regular follow-up examinations are crucial to monitor for signs of complications and ensure optimal lens fit. By adhering to these guidelines, clinicians can help to ensure the safe and effective use of RGP lenses in keratoconus patients.
