Effect of contact lenses on ocular biometric measurements based on swept-source optical coherence tomography
2019
ABSTRACT Purpose: To determine the reliability of swept- source optical coherence tomography in cases in which soft contact lenses cannot be removed when acquiring biometric measurements. Methods: Eight subjects were included and only one eye per participant was analyzed. Each eye was measured six times by swept-source optical coherence tomography with the IOLMaster 700 instrument (Carl Zeiss Meditec, Jena, Germany). Axial length, central corneal thickness, anterior chamber depth, lens thickness, and keratometric measurements were evaluated for the naked eye and while wearing soft contact lenses of three different powers (-1.5, -3.0, and +2.0 D). Results: There were statistically significan…
Corneal backscatter in insulin-dependent and non-insulin-dependent diabetes mellitus patients: a pilot study
2017
ABSTRACT Purpose: To compare central corneal backscatter obtained from Scheimpflug images between patients with insulin-dependent and non-insulin-dependent diabetes mellitus (IDDM and NIDDM, respectively) and healthy controls. Methods: Seven patients with IDDM (7 eyes), eleven patients with NIDDM (11 eyes), and sixteen healthy subjects (16 eyes) were included in this pilot study. Scheimpflug imaging system (Pentacam, Oculus Inc., Germany) was used to obtain optical sections of the cornea. Seven meridians were analyzed for each eye, oriented from 70° to 110°. Optical density values for the central 3-mm and 5-mm zones of the cornea were obtained by image analysis using external software. Resu…
Example of accommodative response to a stationary stimulus
2017
The video in shows the data recorded for a single trial of an experiment with a stationary stimulus and both optical-blur condition and target-blur condition. Reconstructions of the Maltese cross with both conditions are also shown.
Corneoscleral contact lenses fitting on irregular corneas after laser-assisted in situ keratomileusis
2018
ABSTRACT Purpose: We aimed to describe the outcomes of corneoscleral contact lens fitting with multi-aspherical geometry designs in patients with irregular corneas after laser-assisted in situ keratomileusis (LASIK). Methods: This was a retrospective series of 18 patients (age, 26-38 years) selected from an eye clinic database. Participants were required to have unsatisfactory visual acuity with their current contact lenses or spectacles after LASIK for myopia correction. All patients were fitted with corneoscleral contact lenses designed to correct corneal surface irregularities. A diagnostic trial set was used for fitting, and assessments were performed according to a standardized methodo…
Additional file 1 of An initial comparative map of copy number variations in the goat (Capra hircus) genome
2021
Additional file 1:List of CNVs identified in the analysed goats. The Excel file reports the chromosome, the nucleotides position of the CNV start and end (referred to the Btau_4.0 genome assembly), the size of the CNV in bp, the number of valid probes in the CNV (additional probes are included in CNV considering the position between two contiguous regions without 0.175 log2 value; see Methods for the definition of CNV), log2 mean of the probes in the CNV (see Methods), the type of CNV (gain/loss), the goat sample (C = Camosciata delle Alpi; G = Girgentana; MG = Murciano-Granadina; S = Saanaen; numbers after the breed symbols indicate the different animals used in the aCGH experiment), and t…
Example of accommodative response to a sinusoidal stimulus
2017
The video in shows the data recorded for a single trial of an experiment with a sinusoidally moving stimulus at 0.2 Hz and both optical-blur condition and target-blur condition. Reconstructions of the Maltese cross with both conditions are also shown.
