    2. Choroidal Thickness Analysis in Patients with Usher Syndrome Type 2 Using EDI OCT

      Choroidal Thickness Analysis in Patients with Usher Syndrome Type 2 Using EDI OCT

      To portray Usher Syndrome type 2, analyzing choroidal thickness and comparing data reported in published literature on RP and healthy subjects. Methods . 20 eyes of 10 patients with clinical signs and genetic diagnosis of Usher Syndrome type 2. Each patient underwent a complete ophthalmologic examination including Best Corrected Visual Acuity (BCVA), intraocular pressure (IOP), axial length (AL), automated visual field (VF), and EDI OCT. Both retinal and choroidal measures were measured. Statistical analysis was performed to correlate choroidal thickness with age, BCVA, IOP, AL, VF, and RT. Comparison with data about healthy people and nonsyndromic RP patients was performed. Results ...

    4. Evaluation of choroidal thickness via enhanced depth-imaging optical coherence tomography in patients with systemic hypertension

      Evaluation of choroidal thickness via enhanced depth-imaging optical coherence tomography in patients with systemic hypertension

      Purpose: The purpose was to evaluate choroidal thickness via spectral domain optical coherence tomography (SD-OCT) and to compare the data with those of 24-h blood pressure monitoring, elastic features of the aorta, and left ventricle systolic functions, in patients with systemic hypertension. Materials and Methods: This was a case-control, cross-sectional prospective study. A total of 116 patients with systemic hypertension, and 116 healthy controls over 45 years of age, were included. Subfoveal choroidal thickness (SFCT) was measured using a Heidelberg SD-OCT platform operating in the enhanced depth imaging mode. Patients were also subjected to 24-h ambulatory blood pressure monitoring (ABPM ...

    5. Normative data for macular volume with high-definition spectral-domain optical coherence tomography (Spectralis)

      Normative data for macular volume with high-definition spectral-domain optical coherence tomography (Spectralis)

      To establish normative data for macular volume by spectral-domain optical coherence tomography (SD-OCT) in subjects with no known retinal disease. In an academic institutional setting, 50 subjects (age range 20-84 years) with no known retinal disease, best-corrected visual acuity 20/20, and normal intraocular pressure were enrolled. The subjects were divided into 3 age groups: group 1 included subjects 20-40 years of age, group 2 included subjects 41-60 years of age, and group 3 included subjects 61 years of age and older. All subjects underwent a complete ophthalmologic examination and testing, if needed, to rule out any retinal diseases or ...

    6. Intraoperative OCT improves ophthalmic surgery

      Intraoperative OCT improves ophthalmic surgery

      The most popular examination method in ophthalmology today is optical coherence tomography (OCT ). Traditionally, OCT examinations have been performed pre- and post-operatively in vitreo-retinal surgery. While this application of the technology has enabled outcomes to be measured and results to be documented, surgeons have not had the ability to incorporate the results to improve surgical treatments. But with considerable advances to OCT—including high-definition OCT (HD OCT), 3D visualization , and adaptive optics —the integration of these methods into the surgical microscope is logical. The technology is now helping ophthalmologists carry out delicate eye surgeries. In today's integrated microscopy systems ...
