          Abstract

          Objective:

          To measure the frequency of uncorrected ametropia in children with 2 to 8 weeks of persistent headache referred to ophthalmic outpatient department for evaluation.

          Methods:

          This cross sectional study was conducted at CMH Gujranwala from March 2018 to November 2018.A total of 262 children, aged from 5 to 16 years, with 2 to 8 weeks history of persistent headache underwent detailed ophthalmic assessment for refractive errors, and other ophthalmic evaluation. Children with ametropia, confirmed with cycloplegic refraction and post-mydriatic testing were prescribed with glasses. Patients without any ophthalmic findings were referred back to pediatrics department for further evaluation.

          Results:

          Mean age of study population was 8.97 ± 3.16 years. Mean duration of headache was 5.03 ± 1.81 weeks. Ametropia was found in 56 (21.4%) children, while 206 (78.6%) had no refractive error. Out of children with ametropia, 20 (35.7%) had myopia, 24 (42.8%) had astigmatism and 12 (21.5%) had hypermetropia. There was no difference in ametropic children and children without ametropia with respect to gender (p=0.73), age (p=0.54) and duration of headache (p=0.71).

          Conclusion:

          A significant proportion of children with ametropia have initial symptoms of headache. Any child with un-explained headache must undergo ophthalmic evaluation to diagnose refractive error, if any.

          The evolution of headache from childhood to adulthood: a review of the literature

          Headache is one of the most common disorders in childhood, with an estimated 75% of children reporting significant headache by the age of 15 years. Pediatric migraine is the most frequent recurrent headache disorder, occurring in up to 28% of older teenagers. Headaches rank third among the illness-related causes of school absenteeism and result in substantial psychosocial impairment among pediatric patients. The aim of this study was to clarify the evolution of the clinical features of primary headache in the transition from childhood to adulthood through a review of relevant data available in the PubMed and Google Scholar databases for the period 1988 to July 2013. The search strategy identified 15 published articles which were considered eligible for inclusion in the analysis (i.e. relevant to the investigation of pediatric headache outcome). All were carried out after the publication of the first version of the International Classification of Headache Disorders (ICHD-I). The availability of data on the evolution of primary headaches over a period of time is important from both a clinical and a public health perspective. The identification of prognostic factors of the evolution of headache (remission or evolution into another headache form) over time should be an objective of future headache research for the development of prevention strategies. Given that headache is a major factor contributing to school absenteeism and poorer quality of life not only in childhood but also in adolescence, understanding the natural history and the management of the different headache forms is vital for our future.

            A community-based study of asthenopia in computer operators

            Context: There is growing body of evidence that use of computers can adversely affect the visual health. Considering the rising number of computer users in India, computer-related asthenopia might take an epidemic form. In view of that, this study was undertaken to find out the magnitude of asthenopia in computer operators and its relationship with various personal and workplace factors. Aims: To study the prevalence of asthenopia among computer operators and its association with various epidemiological factors. Settings and Design: Community-based cross-sectional study of 419 subjects who work on computer for varying period of time. Materials and Methods: Four hundred forty computer operators working in different institutes were selected randomly. Twenty-one did not participate in the study, making the nonresponse rate 4.8%. Rest of the subjects (n = 419) were asked to fill a pre-tested questionnaire, after obtaining their verbal consent. Other relevant information was obtained by personal interview and inspection of workstation. Statistical Analysis Used: Simple proportions and Chi-square test. Results: Among the 419 subjects studied, 194 (46.3%) suffered from asthenopia during or after work on computer. Marginally higher proportion of asthenopia was noted in females compared to males. Occurrence of asthenopia was significantly associated with age of starting use of computer, presence of refractive error, viewing distance, level of top of the computer screen with respect to eyes, use of antiglare screen and adjustment of contrast and brightness of monitor screen. Conclusions: Prevalence of asthenopia was noted to be quite high among computer operators, particularly in those who started its use at an early age. Individual as well as work-related factors were found to be predictive of asthenopia.

              Relationship between habitual refractive errors and headache complaints in schoolchildren.

              Refractive error (RE) is considered to be a possible cause for headaches. We aimed to gain insight into the relation between habitual RE (sphere and astigmatism) and headache complaints. In a cross-sectional study the habitual refractive state of 487 children, aged between 11 and 13 years, was measured using an autorefractometer (Topcon, RM-8000B). Headache complaints were measured using a questionnaire. Data were analyzed using Pearson correlation coefficients, bivariate analysis, and multiple logistic regression analysis. For right eyes we found 15% habitual myopia +0.50 D; habitual astigmatism > 0.25 D was found in 33% of children. Pearson R between right and left eyes was 0.76 for the spherical component and 0.42 for the cylindrical. In the total group of children 70% reported the occurrence of headache in the last year. These headaches were reported as "often or frequent" by 37% of children, "severe" by 15%, "with long duration" by 45%, and "with severe burden" by 27%. In the total sample we found various associations between gender, sphere/cylinder components of habitual RE, and headache complaints. Headache was reported more in girls than in boys. Of the total variance of headache complaints in girls, the sphere component of habitual RE explained 4% of frequency, 6% of intensity, 2% of duration, and 2% of amount of burden. Of the total variance of headache complaints in boys the cylinder component of habitual RE explained 3% of frequency, and 4% in amount of burden. Habitual RE and headache complaints are relatively common conditions in schoolchildren aged between 11 and 13 years. Headache complaints showed a small but statistically significant association with the sphere component of habitual RE in girls and the cylinder component of habitual RE in boys. The associations found between habitual RE and headache complaints indicate that habitual RE might be a risk factor for headache in children.
