Abstract:

To compare the interoperator repeatability of tear meniscus height (TMH) measurements obtained with a keratograph and Fourier-domain optical coherence tomography (FD-OCT) and to assess the agreement between the methods.Forty-seven eyes with DED and 41 healthy eyes were analyzed using the Schirmer test I and tear breakup time test (TBUT). The TMH was measured three times with each device. The repeatability of measurements was assessed by within-subject standard deviation (Sw), repeatability (2.77 Sw), coefficient of variation (CoV) and intraclass correlation coefficient (ICC).

Abstract:

Purpose: To evaluate the compatibility and usability of test results obtained from the IDRA and Keratograph 5M in clinical settings by comparing their performance in patients with dry eye disease.Methods: From December 27 to 30, 2022, a study was conducted on 30 patients diagnosed with dry eye utilizing both the Keratograph 5M and IDRA devices. The parameters compared and analyzed included lipid layer thickness, tear meniscus height, tear film break-up time, and meibography. A paired t-test was used for statistical comparison. The lipid layer thickness in the Keratograph 5M was graded on a sca

Purpose: To investigate the effect of order of examination on the results of noninvasive keratograph tear film evaluation using Keratograph5M in dry eye patients.Methods: One hundred and four patients with dry eye symptoms were analyzed retrospectively. All patients underwent bilateral noninvasive tear film evaluation using measurements of tear meniscus height (TMH) and noninvasive keratograph break-up time (NIKBUT) obtained using Keratograph5M. Measurements were performed sequentially in the order of right TMH, left TMH, right NIKBUT, and left NIKBUT.Results: There was no statistically signif

Purpose: To evaluate the effects of the non-invasive keratograph break-up time on the repeatability of keratometric measurements derived using the Keratograph 5M in patients with dry eye syndrome.Methods: Thirty-six patients with dry eye and 30 controls were enrolled. We measured keratometric values twice in all subjects and explored whether the two measurements differed by more than 0.5 diopter (D) (the absolute value). We also evaluated the relationship between the absolute difference and the non-invasive keratograph break-up time (NIKBUT).Results: The intraclass correlation coefficients for

Abstract:

To prove the role of high-tech investigation in monitoring corneal morphological changes in patients with neurotrophic keratopathy (NK) using Keratograph 5M (K5M) and anterior segment OCT (AS-OCT), corneal healing was monitored with Keratograph 5M (Oculus, Wetzlar, Germany) and AS-OCT (DRI, Triton, Topcon, Tokyo, Japan) in 13 patients (8F and 5M), aged from 24 to 93 years (67.8 ± 19) with severe NK, who were treated with Cenegermin 0.002% (20 μg/mL) (Oxervate®, Dompè, Farmaceutici Spa, Milan, Italy).

Abstract:

Vitamin D is important to human health with a variety of systemic diseases linked to vitamin D deficiency. The effect of a two month treatment of a vitamin D oral supplement on the ocular surface in older people with dry eye and on binocular vision in younger adults with short-sightedness was assessed. Vitamin D had a beneficial effect on symptoms of dry eye in older people and improved the accommodation function in younger adults. This work suggests that the development of vitamin D eye drops might be useful for these conditions.

Neste trabalho foi desenvolvido um novo instrumento para monitoramento computadorizado da curvatura da região central anterior da córnea humana durante cirurgias refrativas. Através da projeção de um anel iluminado na córnea, imagens dos reflexos são digitalizadas e processadas. Algoritmos baseados em técnicas de visão computacional e geometria óptica determinam a curvatura da região central (4mm), com alta precisão e desempenho. Mapas coloridos com códigos de cor em dioptrias (proporcionais ao inverso do raio da curvatura) são gerados para auxiliar o oftalmologista cirurgião no diagnóstico.<b

Abstract:

Sjogren’s syndrome (Sicca Syndrome) is mainly characterized by the presence of dry eye disease (DED). The diagnosis of DED in patients with Sjogren’s syndrome has been limited to tests such as the Schirmer test, tear breakup time (TBUT), and corneal stains; however, currently we can evaluate the functional unit in detail lacrimal, which is affected in patients with dry eye and Sjögren’s syndrome; thanks to technology that provides objective details for this difficult diagnostic. The newer evaluations that provide the greatest diagnostic value for Sjogren’s syndrome are: noninvasive keratograph
