Clinical Optometry

PURPOSE: To assess the prevalence of ocular morbidities and associated factors among hearing-impaired (HI) students at the Embangweni School for the Deaf in Mzimba, Malawi. METHODS: This was an institutional cross-sectional study of HI students at Embangweni School for the Deaf. A series of optometric and audiometric tests was performed, and the results were exported to the Statistical Package for Social Science for statistical analysis (SPSS) version 25. Pearson's chi-square test was used to assess correlations and associations between variables...

INTRODUCTION: Corneal characteristics are unique to each eye and can vary among different levels of refractive errors. However, minimal data are available in the literature on corneal characteristics in myopic Malay school children including the difference between the low myopic group and the moderate myopic group. Therefore, this study aims to determine the corneal characteristics of myopic Malay school children and their associations with axial length. METHODS: A total of eighty-four data samples were extracted from forty-two myopic Malay school children...

COVID-19 is a viral illness that can cause severe respiratory symptoms. COVID-19 has caused a worldwide pandemic that necessitated many countries to perform a national lockdown. In Jordan, a lockdown was imposed by the government. During the lockdown, the hospitals were only dealing with outpatient emergency cases, urgent referrals from primary or secondary health institutions, and inpatients whose medical conditions required keeping them admitted. Elective clinics and surgeries were canceled. At the King Abdullah University Hospital (KAUH), which is the only tertiary center in northern Jordan, we dealt with an unusual case of uncontrolled and advanced primary open angle glaucoma in a 38-year-old pregnant female patient...

INTRODUCTION: Patients expect to have excellent vision and comfort when wearing soft contact lenses. The purpose of this study was to compare the wear experiences of participants with astigmatism when wearing a daily disposable soft toric lens to an established, commonly used reusable toric lens. METHODS: In this crossover study, habitual soft toric lens wearers were fit with a daily replacement soft toric lens (delefilcon A) and a reusable, 1-month replacement soft toric lens (comfilcon A) in a randomized order...

BACKGROUND: To be successful, amblyopia therapeutic techniques must respond when ingenious (shrewd) amblyopic children sabotage treatment effect by discovering ways(1) to alter those therapy aspects they find frustrating. METHODS: Her guardian consented to IRB-approved study outside typical FDA enrollment guidelines for CureSight dichoptic therapy. Acuity (EVA) and stereopsis was by PEDIG protocols. RESULTS: A 6-year-old rural Alaska native girl in foster care had previously been diagnosed with anisometropic amblyopia and treated with spectacles and patching but had poor compliance with BCVA 0...

BACKGROUND: Early diagnosis and management of keratoconus (KC) are important for limiting visual complications of the disease. This study aimed to explore the perspectives of optometrists on the barriers to effective diagnosis and management of KC in Kenya. METHODS: An online questionnaire was distributed to optometrists in Kenya to collect data on barriers to the diagnosis and management of KC. RESULTS: The majority (60.9%) of optometrists were confident in retinoscopy and subjective refraction...

PURPOSE: To evaluate ocular motility (OM) disorders and strabismus in a sample of patients with retinitis pigmentosa (RP) and a control sample. METHODS: In this cross-sectional retrospective analysis, we studied a sample of RP patients with a mean age of 48.74 years and an average visual acuity of 7/10 based on Snellen optotype and a sample of control patients with similar mean age (49 years [men], 47 years [women]) and sex and an average visual acuity of 9.9/10, with the aim of assessing correlations between alteration of OM and strabismus in RP patients based on age, high refractive defect, or severely impaired binocular vision...

Myopia control lenses have been shown to modify visual function; however, it is arguable if these changes are short-term or long-term. We investigated the changes in accommodative behaviour and binocular vision functions of Malay myopic children who participated in a myopia control trial utilising spectacle lenses (n = 40). This article presents baseline accommodation and binocular vision measurements. The mean (± SD) age, spherical equivalent measured by cycloplegic autorefraction, and axial length (AL) for the right eyes were 10...

PURPOSE: To investigate changes in peripheral eye length (PEL) in myopic children undergoing orthokeratology (Ortho-K) treatment for 12 months using MRI. The results were compared to single vision spectacle wearers (SVS). PATIENTS AND METHODS: A total of 70 children with myopia (aged 8-9 years old) were recruited. A total of 45 children were fitted with Ortho-K, and 25 were fitted with SVS. The PEL and axial length (AL) were measured by using MRI 3-Tesla, whereas central and peripheral refraction (PR) measurements were conducted at ±30 degrees horizontally with nasal (N) and temporal (T) intervals of 10°, 20°, and 30° and with an open field autorefractometer (WAM-5500 Grand Seiko)...

INTRODUCTION: Proper access to primary eye care is essential in addressing vision impairment, and tele-eye care examinations are a promising solution that could facilitate this access in many rural or remote areas. Even though remote eye exams are becoming increasingly frequent, comprehensive tele-eye care exams are still limited by the lack of published data. The aim of this study is to compare a comprehensive tele-eye care exam with a gold standard in-person primary eye care exam with an emphasis on refractive measurements, ocular health assessment, confidence level of the eye care providers and patient satisfaction...

BACKGROUND: Visual impairment is a functional limitation of the eye brought on by a disorder or disease that can make it more difficult to carry out daily tasks. Visual impairment causes a wide range of public health, social, and economic issues, particularly in developing nations, where more than 90% of the world's visually impaired people reside. Although many studies conducted in Ethiopia related with the topic, there were focused on childhood visual impairments. OBJECTIVES: To assess the prevalence and factors associated with visual impairment among older adults...

BACKGROUND: The commonest and cheapest treatment modality for correcting refractive error is spectacles or eyeglasses. In Ethiopia, the rate of spectacles under utilization and its impact on visual impairment was not known. OBJECTIVE: To assess spectacles under utilization and associated factors among adults in Hawassa, Ethiopia, 2022. METHODS AND MATERIALS: Community-based cross-sectional study design was conducted from Jan 2021 to May 2022 with a final sample size of 664...

In recent years, advanced diagnostic instruments have become widely available in optometric practices, offering various functions that optimize clinical information gathering. This article focuses on the Medmont Meridia™, a state-of-the-art multipurpose diagnostic device with corneal topography and cutting-edge features. Corneal topography is pivotal in the early diagnosis of corneal disorders, determining baseline ocular surface assessment, helping in contact lens fitting, and monitoring ocular health over time...

PURPOSE: To examine the potential of different head-mounted displays in the rehabilitation of individuals with visual impairment. METHODS: This prospective explorative study conducted between September 2019 and August 2020 included participants with Stargardt disease with moderate to severe visual impairment and a relatively preserved peripheral visual field. AceSight, eSight 3, IrisVision Live, and Jordy were tested. After instruction and training, participants chose two head-mounted displays for home use for two weeks per device...
