    3. Retinochoroidal microvascular changes in newly developed obese children: an optical coherence tomography angiography study

      Retinochoroidal microvascular changes in newly developed obese children: an optical coherence tomography angiography study
      Background: Childhood obesity was associated with retinochoroidal microvascular changes using optical coherence tomography angiography (OCTA), but obesity duration was neglected. Obesity is chronic and progressive and obesity duration is related to microvascular function. Thus, it is important to identify microvascular changes in obese children timely to allow possible interventions with the increase in the number of obese children. This pilot study aimed to characterize retinochoroidal microvascular changes in newly developed ...

    5. Choroid automatic segmentation and thickness quantification on swept-source optical coherence tomography images of highly myopic patients

      Choroid automatic segmentation and thickness quantification on swept-source optical coherence tomography images of highly myopic patients
      Background: Thinning of the choroid has been linked with various ocular diseases, including high myopia (HM), which can lead to visual impairment. Although various artificial intelligence (AI) algorithms have been developed to quantify choroidal thickness (ChT), few patients with HM were included in their development. The choroid in patients with HM tends to be thinner than that of normal patients, making it harder to segment. Therefore, in this study, we ...

    6. Most nonpathological eyes present a small area of hyperreflective Henle's fiber layer on pupil-centered optical coherence tomography

      Most nonpathological eyes present a small area of hyperreflective Henle's fiber layer on pupil-centered optical coherence tomography
      Purpose: Henle's fiber layer (HFL) is hyporeflective and indistinct on pupil-centered optical coherence tomography (OCT). However, a small area of HFL is also found to be hyperreflective on pupil-centered OCT. This study characterized the hyperreflective HFL of healthy eyes on pupil-centered OCT and investigated the possible physiological and functional relationship of hyperreflective HFL. Methods: Subjects with different degrees of ametropia underwent a complete ophthalmologic examination, including binocular function by ...

    7. DHNet: High-resolution and hierarchical network for cross-domain oct speckle noise reduction

      DHNet: High-resolution and hierarchical network for cross-domain oct speckle noise reduction
      Purpose: Optical coherence tomography (OCT) imaging uses the principle of Michelson interferometry to obtain high-resolution images by coherent superposing of multiple forward and backward scattered light waves with random phases. This process inevitably produces speckle noise that severely compromises visual quality of OCT images and degrades performances of subsequent image analysis tasks. In addition, datasets obtained by different OCT scanners have distribution shifts, making a speckle noise suppression model difficult ...

    8. Compressive-sensing swept-source optical coherence tomography angiography with reduced noise

      Compressive-sensing swept-source optical coherence tomography angiography with reduced noise
      Optical coherence tomography angiography (OCTA), as a functional extension of optical coherence tomography (OCT), has exhibited a great potential to aid in clinical diagnostics. Currently, OCTA still suffers from motion artifact and noise. Therefore, in this paper, we propose to implement compressive sensing (CS) on B-scans to reduce motion artifact by increasing B-scan rate. Meanwhile, a noise-reduction filter is specially designed by combining CS, Gaussian filter, and Median filter. Specially ...

    9. Reducing speckle in anterior segment optical coherence tomography images based on a convolutional neural network

      Reducing speckle in anterior segment optical coherence tomography images based on a convolutional neural network
      Speckle noise is ubiquitous in the optical coherence tomography (OCT) image of the anterior segment, which greatly affects the image quality and destroys the relevant structural information. In order to reduce the influence of speckle noise in OCT images, a denoising algorithm based on a convolutional neural network is proposed in this paper. Unlike traditional algorithms that directly obtain denoised images, the algorithm model proposed in this paper learns the ...

    10. Group-wise context selection network for choroid segmentation in optical coherence tomography

      Group-wise context selection network for choroid segmentation in optical coherence tomography
      Choroid thickness measured from optical coherence tomography (OCT) images has emerged as a vital metric in the management of retinal diseases such as high myopia. In this paper, we propose a novel group-wise context selection network (referred to as GCS-Net) to segment the choroid of either normal or high myopia eyes. To deal with the diverse choroid thickness and the variable shape of the pathological retina, GCS-Net adopts the group-wise ...

      MF-Net: Multi-Scale Information Fusion Network for CNV Segmentation in Retinal OCT Images
      Choroid neovascularization (CNV) is one of the blinding ophthalmologic diseases. It is mainly caused by new blood vessels growing in choroid and penetrating Bruch's membrane. Accurate segmentation of CNV is essential for ophthalmologists to analyze the condition of the patient and specify treatment plan. Although many deep learning-based methods have achieved promising results in many medical image segmentation tasks, CNV segmentation in retinal optical coherence tomography (OCT) images is ...

    12. Joint segmentation of multi-class hyper-reflective foci in retinal optical coherence tomography images

      Joint segmentation of multi-class hyper-reflective foci in retinal optical coherence tomography images
      Hyper-reflective foci (HRF) refers to the spot-shaped, block-shaped areas with characteristics of high local contrast and high reflectivity, which is mostly observed in retinal optical coherence tomography (OCT) images of patients with fundus diseases. HRF mainly appears hard exudates (HE) and microglia (MG) clinically. Accurate segmentation of HE and MG is essential to alleviate the harm in retinal diseases. However, it is still a challenge to segment HE and MG ...

      Automatic focus method using interference fringes magnitudes in retinal optical coherence tomography
      In retinal optical coherence tomography (OCT), it is significant to focus the scan beam on the retina layers of the human eye fast to acquire high-quality OCT images. The refrac- tive errors of the human eye are usually compensated by shifting the optical lens in the sample arm manually or electrically. Otherwise, refractive errors of the human eye will cause axial focal shift of the scanning beam and blur the ...

      Development of a handheld compression optical coherence elastography probe with a disposable stress sensor
      Optical coherence elastography (OCE) is a functional extension of optical coherence tomography (OCT). OCE measures a samples deformation under force stimuli. Compression is often used to generate the force stimuli in OCE. In this Letter, we report the development of a handheld quantitative compression OCE probe with a novel stress senor, dedicated to measuring the force. The stress sensor consists of a circular glass window and a metal ring which ...
