Acta Ophthalmologica, Volume 102, Issue 5, Page e842-e850, August 2024.Abstract Purpose The relationship between attention deficit hyperactivity disorder (ADHD) and visual impairment remains poorly understood, and the impact of visual impairment on the development of ADHD is uncertain. The aim of this study was to investigate the refractive profile and ocular biometric characteristics in patients diagnosed with ADHD and ...

Corneal and anterior segment parameters in patients with clinically unilateral pseudoexfoliation syndrome [PDF]
Background: Pseudoexfoliation syndrome (PES) is an age-related systemic condition that predominantly affects ocular structures and is characterized by the deposition of material on the lens, ciliary body, zonules, corneal endothelium, iris, and pupillary

Clinical &Experimental Ophthalmology, Volume 52, Issue 1, Page 22-30, January/February 2024.Abstract Background This study investigated the prevalence, risk factors and severity of corneal tomographic features of keratoconus in Down syndrome (DS). Additionally, previous studies indicate anomalous corneal features in DS, without keratoconus, this study characterised corneal features in DS without keratoconus.

Detecting Keratoconus in Adolescents with Anterior Segment Optical Coherence Tomography
Journal of Ophthalmology, Volume 2024, Issue 1, 2024.Purpose. Assessing the applicability of an algorithm developed for keratoconus detection in adolescents. This algorithm relies on optical coherence tomography (OCT) and incorporates features related to corneal pachymetric and epithelial thickness alterations. Methods.
