“…For RE subjects, the light cannot bend correctly because of the uneven shape of the eye, which leads to the lack of light concentration to focus on an image. Therefore, uncorrected RE has long-term implications on patient quality of life, particularly among children [ 34 ]. The current study suggests that subjects with RE (myopia and hyperopia) have a significantly high level of dry eye compared with participants with normal eyes.…”

Dry eye symptoms are associated with refractive errors. We aimed to measure the tear evaporation rate (TER) in subjects with refractive errors (RE) using a portable evaporimeter. This nonrandomized, case–control, and observational study included 75 subjects, including 25 subjects aged 18–38 years (28.8 ± 6.8 years) with myopia (−0.75 to −3.75 D) and 25 subjects aged 18–39 years (27.7 ± 5.5 years) with hyperopia (+0.50 to +3.75 D). In addition, a control group of 25 subjects with emmetropic eyes aged 20–30 years (23.6 ± 2.6 years) was recruited. The ocular surface disease index (OSDI) was completed, followed by the TER measurements using a portable evaporimeter. The OSDI score and TER measurements showed dry eye symptoms in 36% and 48% of myopic subjects, respectively. For hyperopic participants, dry eye was observed in 24% and 56% of the subjects based on the OSDI and TER scores, respectively. Significant differences (Mann-Whitney U test; p < 0.001) were found among the OSDI and TER scores recorded within the study (myopic and hyperopic subjects) and control groups. Significant strong positive correlations were detected between the OSDI and TER scores in both myopic (p = 0.004; r = 0.559) and hyperopic (p = 0.001; r = 0.619) subjects. The TER scores were significantly higher in subjects with RE (myopic and hyperopic) as compared with individuals with normal eyes.

“…13 Several epidemiological studies have shown that caesarean delivery and preterm birth increase the risk of childhood myopia. [14][15][16][17] For example, preterm birth may affect ocular development or later emmetropisation, and it may affect the development of the refractive status through a more complicated mechanism. [18][19][20][21][22] In addition, breast feeding in early life may stimulate ocular development, as the docosahexaenoic acid and arachidonic acid in breast milk may affect retinal and neural development, therefore decreasing the risk of myopia.…”

ObjectivesIn this cross-sectional survey, we sought to determine the prevalence of and the influence of prenatal and neonatal factors on childhood visual impairment without correction (VIUC) in a paediatric population from Guangzhou, China.SettingThe health survey covered 11 administrative districts in Guangzhou, including 991 schools.ParticipantsAll of the primary and middle school students in Guangzhou were invited to complete an online questionnaire with the help of their parents. The results of physical examinations were reported by school medical departments. The results of the questionnaire were collected by the researchers. In total, 253 301 questionnaires were collected.Primary outcome measuresThe students’ uncorrected visual acuity (UCVA) was examined by trained optometrists by standard logarithmic visual acuity charts. VIUC was defined by UCVA (of the better eye) (UCVA <6/12) with three levels: light VIUC (UCVA ≥6/18 to <6/12), mild VIUC (UCVA ≥6/60 to <6/18) and severe VIUC (UCVA <6/60).ResultsA total of 39 768 individuals (15.7%) had VIUC, and the rate was much higher among grade 10 to 12 students (51.4%) than among grade 1 to 6 students (6.71%). The following factors were significantly associated with an increased risk of VIUC: female gender, high birth weight, formula feeding, not having siblings, higher level of parents’ education, parental myopia, much homework time and little outdoor activity. Delivery mode was not associated with the risk of VIUC.ConclusionsThis study validates known major prenatal/genetic, perinatal and postnatal factors for childhood VIUC. In conclusion, prenatal and perinatal factors can affect the onset of childhood VIUC, but parental myopia and postnatal factors are the main factors.

Background: Refractive error is defined as a status of refraction. They happen when the shape of your eye keeps light from focusing correctly on your retina (a light-sensitive layer of tissue in the back of your eye). Refractive errors are the most common type of vision problem but many don’t know that they could be seeing well.Methods: This study was a cross sectional hospital-based study of 197 children carried out in ophthalmology department of Era Medical College, Lucknow. The study of population comprised of all the children in 5-20 years’ (78 male 119 female) age group in the rural area. In this study compressive examination prevalence of myopia and hypermetropia. The assess refractive error among study with ‘hine retinoscopy’. Myopia considered grater or equal -0.50 and hyperopia is grater and equal +0.50.Results: The crossed section hospital-based study 197 children examined 78 male and 119 female. The uncorrected ametropia in children was 82.2%. The highly prevalence of myopia 46%, hypermetropia 5%, astigmatism 31%. The most highly significant refractive error 16-20 year of age.Conclusions: The prevalence of ametropia is fined among children in hospital visit. Need for regular routine cheek up proper ophthalmic assessment examination of eye and full proper diet and distance with digital gadget.
