Screening of Primary School Children for Amblyopia and Amblyogenic Factors in Central Cairo, Egypt.

Screening of Primary School Children for Amblyopia and Amblyogenic Factors in Central Cairo, Egypt. J Ophthalmol. 2018;2018:8425319 Authors: Rashad MA, Abd Elaziz KM, Fawzy SM, Abdel Latif AAM, Abdel Latif MAM Abstract Objective: To measure the prevalence of amblyopia and amblyogenic factors among primary school children and to evaluate distance visual acuity (VA) as a screening test to detect amblyopia and define its cutoff value. Subjects and Methods: A cross-sectional study was conducted on primary school children in two schools in Central Cairo. Children underwent assessment of visual acuity using Landolt broken ring. Comprehensive ophthalmologic examination was performed for amblyopia suspects at the Ophthalmology Department of Ain Shams University Hospitals, including reassessment of best-corrected visual acuity (BCVA) using the same chart. Results: A total of 352 children were examined. Reduced screening VA (amblyopia suspect) was detected in 47 subjects (13.35%) proved amblyopia after comprehensive examination was 1.98% (7 cases). Refractive errors (REs) were present in all suspected and proved amblyopia cases (100%) but was only present in 11.6% of nonamblyopic students (P

Material and Methods: Medical records of patients who underwent posterior chamber phakic IOL (Eyecryl Phakic IOL, Biotech Vision Care, Ahmedabad, India) implantation for surgical correction of myopia were retrospectively reviewed. Only patients with at least a one-year follow-up were included. Manifest refraction, uncorrected distance visual acuity (U...

Abstract OBJECTIVE: To conduct a systematic review and meta-analysis of the association of blood vitamin D (25-hydroxyvitamin D, 25(OH)D) concentration and vitamin D pathway genes with myopia. METHODS: We searched the MEDLINE and EMBASE databases for studies published up to 29 January 2018. Cross-sectional or cohort studies which evaluated the blood 25(OH)D concentration, blood 25(OH)D3 concentration or vitamin D pathway genes, in relation to risk of myopia or refractive errors were included. Standard mean difference (SMD) of blood 25(OH)D concentrations between the myopia and non-myopia groups was calculated...

We thank the reader for this valuable comment.1 In our study,2 children filled out the questionnaire with the help of their parents because information on parental myopia, parental education level, and other information might be beyond the understanding of children of young age. Although we agree with the reader that potential biases might have taken place, this method has been widely used in epidemiologic studies in children. In the article, we have recognized and mentioned the possible information biases in the discussion section.

Keratoconus is an ectatic corneal disorder, characterized by progressive thinning of the stroma and cone-like protrusion, which may lead to irregular astigmatism, myopia and severe visual impairment [1]. Although corneal topography has traditionally been the most sensitive method used to detect keratoconus [1], tomography (e.g., a Scheimpflug based imaging system such as the Pentacam, Optikger äte Oculus GmbH, Wetzlar, Germany) is currently the best and most widely available technique to diagnose early keratoconus [2].

We read with interest the study “Long-term Effect of Scleral Encircling on Axial Elongation” by Lee and associates.1 Following a retrospective analysis of myopic patients undergoing surgery for retinal detachment (RD), the authors concluded that encircling the sclera may accelerate progression of myopia by significantly increa sing axial length (AL). The change in AL was nearly 8 times higher as compared to fellow eyes in the short term, and nearly 10 times higher in the long term.

Authors: Agarwal S, Thornell E, Hodge C, Sutton G, Hughes P Abstract Background: Laser-Assisted in situ Keratomileusis (LASIK) can induce corneal aberrations that can impact vision and patient satisfaction. Recent developments in laser technologies have helped minimise these aberrations. Objective: To assess the quality of vision and change in Higher-Order Aberrations (HOAs) following wavefront-optimized LASIK in low-myopic astigmatic patients. Methods: LASIK was performed on a total of 76 eyes in patients with myopia
