Curves and surfaces in the context of optometry. Part 1: Curves*

African Vision and Eye Health, 2005
This paper introduces the differential geom-etry of curves in Euclidean 3-space, the motiva-tion being the writer’s belief that, despite their fundamental importance, curves are inadequate-ly treated in optometric educational programs.

Prevalence and Associated Factors of Self‐Reported Myopia Among Undergraduate Students in the Northern Region of Bangladesh: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Myopia is an increasingly important public health concern worldwide, particularly among young adults. While previous research has applied machine learning techniques to identify myopia‐related risk factors, evidence based on traditional statistical models using the same datasets remains limited. This study aimed to estimate

Early choroidal thickness changes predict myopia control response to peripheral defocus spectacles in premyopic children

Optometry and Vision Science, Volume 103, Issue 5, May 2026.
ABSTRACT Purpose To investigate whether early changes in choroidal thickness predict long‐term treatment response to peripheral defocus spectacles in premyopic children with insufficient hyperopic reserve. Methods Two hundred children aged 6–8 years with cycloplegic spherical equivalent refraction +0.25 to +0.75 diopters (D) and annual hyperopic ...

Orthokeratology in Moderate Myopia: A Study of Predictability and Safety

Journal of Ophthalmic & Vision Research, 2020
Purpose: Literature is relatively silent on safety profile and predictability of orthokeratology lenses in terms of myopia correction and prevention of further progression, especially in semi-tropical countries; this study was designed to fill this gap.

Exploring the role of low‐dose atropine in myopia management in children with inherited retinal diseases

Optometry and Vision Science, Volume 103, Issue 4, April 2026.
ABSTRACT Purpose This study aimed to evaluate the effectiveness of low‐dose atropine in slowing myopic progression in children with inherited retinal diseases (IRDs) and myopia. Methods Retrospective study of children with IRDs, comparing myopia progression between those who received atropine drops and those who did not was conducted.
