Abstract

Introduction: Myopia is major public health concern that has become increasingly common. Severe myopia has become one of the main causes of untreatable vision loss throughout the world, often due to its irreversible complications. Studies shows atropine can reduce myopia progression in children. Currently, there are no guidelines for the use of atropine specifically to control myopia progression. This study was made to review the efficacy of various atropine doses in controlling myopia progression. Methods: Literature searching was conducted in four online databases (PubMed, EBSCOhost, ScienceDirect, and Scopus. Search terms included were “Atropine” and “Myopia”. Validity was assessed using assessment tool from Cochrane. Efficacy was evaluated using myopia progression in spherical equivalent per year and axial lengthening per year. Results: Sixteen randomized controlled trial studies fulfilled our inclusion criteria and eligibility screening. Overall, atropine shows favorable results in spherical equivalent progression (D/year) compared to control, with SMD = -1.13, 95% CI (-0.58, -1.68). Less axial elongation (mm/year) was observed in atropine group, with SMD = -1.28, 95% CI (-0.18, -2.37). Atropine 0.01% concentration shows overall significantly better myopia progression and axial lengthening compared to control, with SMD = -0.76, 95% CI (-0.08, -1.44) and SMD = -0.63, 95% CI (-0.14, -1.12), respectively. Higher atropine doses showed larger effect sizes with higher occurrence of adverse effects. Conclusion: Atropine eye drops in various doses shows overall effective myopia control in spherical equivalent and axial lengthening. Atropine 0.01% has significant myopia progression inhibition with less adverse effects than higher doses.

Abstract

Introduction : Corneal scarring is part of corneal wound healing response to injury, surgery, or infection to the cornea. Corneal scarring causes significant visual reduction. This case report highlights visual acuity (VA) improvement in patient with corneal scarring following rigid glass permeable contact lens (RGP-CL) Case Illustration : A 25 year-old male presented blurry vision in right eye (RE) due to trauma. His VA was 3/60 on RE and 6/6 on left eye (LE). The best corrected visual acuity (BCVA) of RE was 6/45 (S-1.25 C-5.00 X 180°). Slit lamp examination of RE showed corneal scarring in central area and deep neovascularization. Keratometry readings obtained 39.50D (8.48mm) at 170 degree and vertical curvature of 44.00D (7.68mm) at 80 degree, with markedly irregular mires of RE. A trial fitting was performed for RE by using tisilfocon A lens with base curve of 8.30 mm, power S-4.00D and diameter 9.20 mm. The over-refraction with trial lens obtained a total refractive error of S-6.00 with cylindrical correction neutralize with RGP. The achieved BCVA by over-refraction was 6/45 with comfortable fit. Discussion : Rigid permeable lens (RGP) is an option in dealing with irregular astigmatism due to corneal scarring. The RGP fitting works best especially when the corneal scarring is not in the center of visual pathway. Rigid lens works by providing tear-lens power and creating smooth surface to neutralize the irregular cornea. Good RGP-CL fitting could help patient with corneal carring gain better VA. Conclusion : Good rigid permeable contact lens fitting could help patients with corneal scarring gain better VA.

Abstract

Ophthalmologists rely on wet lab training for both diagnostic procedures and surgical techniques. Existing wet lab devices are limited to surgical training and lack functionality for performing required perioperative diagnostic examinations. This study aimed to develop an affordable, easily manufactured eye holder to enhance ophthalmology training for wet lab simulations. A three-dimensional (3D)-printed animal eye holder was designed in 3D with a funnel-shaped structure resembling an orbital eye socket. The design was optimized for optimal wet lab activities. The animal eye holder device demonstrated potential use for ultrasound biometry, handheld keratometry, tonometry, and ophthalmological surgical training. These activities can be performed effectively after the animals’ eyes are stabilized inside the holder in flat and inclined positions. This innovative animal eye holder is the first designed to provide flexible diagnostic practice and surgical training, especially during wet lab activities.

Abstract

Introduction: The increased use of Visual Display Terminals (VDTs) allows close work with continuous screen gazing during working hours. Close work forces the eyes to accommodate resulting in contraction of the ciliary system. This sustained contraction will lead to ciliary system weakness, making close work a risk factor for premature presbyopia. Methods: The research design was cross sectional. It was conducted on employees of health centers in Bekasi district who were under 40 years old with more than 1 year of service as employees and had used VDT for at least 1 year. Employees filled out an interview form voluntarily then the answers would be verified according to presbyopia and finally measured the amplitude of accommodation for respondents who met the presbyopia criteria. The research was carried out throughout December 2023. The collected data were statistically processed using the SPSS 26 application tool.Results: Of the 100 respondents who filled out the interview form and then verified and measured, 22 people (22%) had premature presbyopia. Age (p-value 0.014), type of VDT (p-value 0.049) and habit of working with VDT for 1 hour non-stop (p-value 0.016) were associated with premature presbyopia because they had a p-value <0.05. Based on multivariate test, the factor of working with 1 hour non-stop VDT was the only factor with p-value 0.018 and OR 3.78995% CI 1.255-11.445.Conclusion: There is an association of VDT use with the incidence of premature presbyopia in office workers by 22%. With the most significant influence owned by the factor of working with VDT 1 hour non-stop.
