    2. Assessment of Retinal Nerve Fiber Layer Thickness Using Optical Coherence Tomography in Patients with Type 2 Diabetes Mellitus

      Assessment of Retinal Nerve Fiber Layer Thickness Using Optical Coherence Tomography in Patients with Type 2 Diabetes Mellitus
      Background: Diabetic retinopathy (DR) is the most common ocular complication of diabetes mellitus (DM) and considered one of the leading causes of blindness in developed countries. Diabetic retinopathy is predominantly a microangiopathy in which high glucose levels can make small blood vessels particularly, vulnerable to damage. Objective: The aim of this work was to assess the thickness of peripapillary retinal nerve fiber layer (RNFL) measured by Swept Source optical coherence ...

    3. Ophthalmic operation microscope

      Ophthalmic operation microscope
      In an ophthalmic operation microscope, an illumination optical system illuminates a patient's eye with illumination light. An observation optical system is used for observing the patient's eye illuminated. An objective lens is disposed in an observation optical path. An interference optical system splits light from a light source into measurement light and reference light, and detects interference light generated from returning light of the measurement light from the ...

    4. Fundus analysis apparatus and fundus observation apparatus

      Fundus analysis apparatus and fundus observation apparatus
      A fundus analysis apparatus includes a storage, an area setting unit, and a morphological information generating unit. The storage is configured to store OCT information acquired by applying optical coherence tomography to the fundus of an eye. The area setting unit is configured to set a front area corresponding to a front surface of the lamina cribrosa and a rear area corresponding to a rear surface of the lamina cribrosa ...

    5. Detection of missampled interferograms in frequency domain OCT with a k-clock

      Detection of missampled interferograms in frequency domain OCT with a k-clock
      Optical coherence tomography light sources can be non-linear and attempts to linearize them can lead to asynchrony between the light source and A-line scans and missampling in the scans causing signal noise. Accordingly, a system and methods are provided herein to detect missampling by obtaining a plurality of interferograms; providing at least two wavenumber reference signals at different wavenumbers, wherein the wavenumber reference signals comprise attenuated or enhanced portions of ...

    7. Retinal Arteriole Pulse Waveform Analysis Using a Fully-Automated Doppler Optical Coherence Tomography Flowmeter: a Pilot Study

      Retinal Arteriole Pulse Waveform Analysis Using a Fully-Automated Doppler Optical Coherence Tomography Flowmeter: a Pilot Study
      Purpose : To evaluate the repeatability and reproducibility of the measurement of retinal arteriole pulse waveforms using a novel fully-automated Doppler optical coherence tomography (DOCT) flowmeter in healthy subjects. Methods : Twenty eyes of 20 healthy subjects were included to test the intrasession repeatability of pulse waveform analysis. DOCT measurements were performed based on a newly developed instantaneous Doppler angle measurement method. Upstroke time (UT), which is the time from the minimum ...
