Central Corneal Thickness Measurements With Different Imaging Devices: Ultrasound Pachymetry, Noncontact Specular Microscopy and Tono-pachymetry

Beyoglu Eye Journal, 2022
Investigation of the compatibility between central corneal thickness (CCT) measurements in healthy eyes by comparing standard ultrasound pachymetry (USP) with noncontact tono-pachymetry (NCT) and specular microscopy (SM) devices was aimed.Forty-five eyes of 45 healthy volunteers aged between 18 and 60 years were included in this study. CCT of all cases

Progressive hemifacial atrophy with ciliary body atrophy and ocular hypotony

Indian Journal of Ophthalmology, 2015
Progressive hemifacial atrophy (PHA) is a disease of unknown etiology affecting one-half of the face. Ocular involvement is uncommon. Atrophy of iris is rare, with only a few cases of partial atrophy being reported in the literature.

Variation in measuring and ophthalmic factors correlating with central corneal thickness in the Northern Finland birth cohort eye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess the correlation between optical coherence tomography (OCT) and ultrasound pachymetry (USP) as methods for analysing central corneal thickness (CCT) and to evaluate ophthalmic factors affecting CCT. Methods The eyes of 3070 subjects of the Northern Finland Birth Cohort (NFBC) were examined at the age of 45–49 years.

Inter-examiner agreement of the AS-OCT Visante corneal thickness

Journal of Optometry, 2011
Purpose: To determine the inter-examiner agreement of the manual values of central and peripheral corneal thickness as measured by optical coherence tomography (AS-OCT Visante) and to assess the agreement between AS-OCT Visante pachymetry, Orbscan II and

Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Context Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one‐third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro‐metabolic phenotype involving the retina,

Understanding higher‐order aberrations in keratoconus

Optometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...
