Abstract:

Hypermetropia (hyperopia) is a refractive error of the eye in which parallel light rays focus behind the macula luthea without accommodation giving an unclear retinal image. The involvement of accommodation in correction of far-sightedness leads to the following three clinical types of hyperopia: total, latent and manifest. Minor hyperopias can be successfully corrected by accommodation higher than +3.0D. If not corrected timely, they may cause amblyopia and esotropia, while high hyperopic anisometropia of a hyperopic eye, usually results in an amblyopic eye. The study included 200 children (4

Abstract:

We investigated longitudinal changes in the spherical equivalent refractive error (SE) in hyperopic children with or without refractive accommodative esotropia (AccET). A total of 456 patients met the inclusion criteria: 190 (41.7%) in the hyperopic control group and 266 (58.3%) in the AccET group. All patients received at least 3 years of follow-up after spectacle prescription. Subgroups were divided according to age when spectacles were prescribed, presence of amblyopia, or initial SE. Longitudinal changes in SE in children with hyperopia showed a gradual decrease, although SE of younger chi

Abstract:

Refractive findings were determined with a retinoscope for two species of kangaroos. The 10 eyes studied were found to be hyperopic between 1.5 and 2.0 dioptres, with and without cycloplegia. Due to the large size of the eye, the hyperopia cannot be explained on the basis of retinoscopic reflection from the vitreous-retina border. The hyperopia may be due to an as yet unexplained artefact or it may reflect indifference to optical quality.

Abstract:

Myopia has been extensively documented as a significant risk factor for cataracts; however, the relationship between hyperopia and cataract development remains poorly understood. Given the distinct refractive profiles of myopia and hyperopia, hyperopia may confer a protective effect against cataracts. In this study, we employed Mendelian randomization (MR) to examine the causal association between hyperopia and cataracts. A 2-sample MR framework was utilized to examine the causal relationship between hyperopia and cataracts, with multivariable MR implemented to account for potential confoundin

Abstract:

Several refractive techniques are available for the treatment of hyperopia. Conductive keratoplasty (CK) is a safe and non-ablative procedure suitable for the treatment of low hyperopia and presbyopia. Due to the high rate of regression, it is not a commonly used technique. There is minimal literature about the use of refractive procedures for the treatment of hyperopic regression after CK. We report a case of a 49-year-old man who had undergone bilateral CK 15 years before for the correction of his hyperopia.

ObjectivesThis study aimed to quantitatively evaluate optic nerve head and retinal vascular parameters in children with hyperopia in relation to age and spherical equivalent refraction (SER) using artificial intelligence (AI)-based analysis of colour fundus photographs (CFP).Methods and analysisThis cross-sectional study included 324 children with hyperopia aged 3–12 years. Participants were divided into low hyperopia (SER+0.5 D to+2.0 D) and moderate-to-high hyperopia (SER≥+2.0 D) groups.

PURPOSE: This systematic review and meta-analysis aimed to provide the available data on the prevalence of childhood hyperopia in the eastern Mediterranean region (EMR). METHODS: The study used preferred reporting items for systematic reviews and meta-analyses, 2020. The articles were searched in six online databases (Web of Sciences, Scopus, Index Medicus for the EMR, ProQuest, PubMed, and Medline). For studies published on the prevalence of hyperopia in the EMR from January 2000 to May 2022. The reviewed data were grouped by age, gender, and refractive measurement technique, hyperopia was de

One of the many factors that have been discovered to aggravate the problem is a lack of zonular support for the lens capsule. The prognosis for non-progression of contractions after Nd:YAG anterior capsulotomy is quite excellent. This study aims to present a complete resolution of the hyperopic shift in an anterior capsular contraction syndrome (ACCS), a rare complication of cataract surgery. Case Illustrati

Purpose. To evaluate the efficacy of the “fogging test,” performed with a +2 diopters (D) lens, in the exclusion of clinically significant hyperopia in school-aged children. Methods. We studied 54 children between 5 and 11 years of age, with 10/10 best-corrected bilateral visual acuity (VA) without significant degree of correction. VA was assessed in each eye with a “bilateral” +2 D sphere over-refraction followed by cycloplegic retinoscopy. The capacity of the test to detect hyperopia of ≥+2 D and ≥+1.5 D was evaluated by examining the respective receiver operating characteristic (ROC) curves

Abstract:

AbstractThe eyes of growing chicks adjust to correct for myopia (eye relatively long for the focal length of its optics) or hyperopia (eye relatively short for the focal length of its optics). Eyes made functionally hyperopic with negative spectacle lenses become myopic and long, whereas eyes made functionally myopic with positive spectacle lenses become hyperopic and short. We report here that these compensatory growth adjustments occur not only in normal eyes but also in eyes unable to accommodate (focus) because of lesions to the Edinger-Westphal nuclei. Thus, at least in chicks, accommodat

Abstract:

Kiwis are flightless, nocturnal birds with relatively small rudimentary eyes. Numerous reports indicate that these birds are myopic. Refractive measurements, carried out by retinoscopy and photorefraction, on two brown kiwis (Apteryx australis) show that they are hyperopic by amounts varying between 2.3 and 7.0 diopters. This variation is presumably an indication of accommodative ability. Since the kiwi eye is relatively small and since the refractive measurements may be based on reflection from the vitreous surface of the retina, all or part of the hyperopia measured may be artifactual.
