      Epithelial tissue thickness improves optical coherence tomography’s ability in detecting oral cancer
      Background OCT is a non-invasive imaging technique that enables the measurement of epithelial thickness and architectural changes, which can help in the diagnosis of pre-cancerous and cancerous lesions. The purpose of the study was to assess whether epithelial tissue thickness improves optical coherence tomographys ability in detecting oral cancer. Patients and Methods Surgically resected oral margins from 60 patients diagnosed with oral squamous cell carcinoma were subjected to OCT. Three ...

      OCT in the diagnosis of head and neck pre-cancerous and cancerous cutaneous lesions: An immediate ex vivo study
      Background Optical coherence tomography (OCT) has been shown to reliably identify skin changes with the combined advantage of resolution and penetration depth. The objective of this study was to assess the accuracy of OCT in diagnosing various skin pathologies, using pre-set diagnostic criteria, by two reviewers blinded to the actual diagnosis. Material and methods This immediate ex-vivo study included skin specimens from 103 patients with suspicious skin lesions. In total ...

      Anterior segment optical coherence tomographic angiography assessment of acute chemical injury
      Purpose To compare routine clinical examination with optical coherence tomography angiography (OCTA) for the assessment of limbal conjunctival ischemia following a chemical burn. Setting Validity analysis Methods We assessed ten participants (15 eyes) with an acute chemical injury. Clinical photographs were used to determine the extent of any limbal conjunctival epithelial defect and ischemia. These were compared with the extent of limbal ischemia identified on OCTA images of the ocular ...

      Early Phase Disease Modification Trials with Selisistat and Optical Coherence Tomography as a Biomarker in Huntington’s Disease (Thesis)
      Huntingtons disease (HD) is a monogenic neurodegenerative disorder with no known cure. Selisistat is a novel, highly potent Sirt1 inhibitor with supportive pre-clinical data. Facilitation of autophagy and amelioration of transcriptional dysregulation are proposed as mechanisms of action. A first in disease Phase 1B study showed safety and tolerability. The peripheral immune dysfunction in HD could be modulated by Sirtuins which have both pro and anti-inflammatory activities. However selisistat did ...

      Impact of segmentation density on spectral domain optical coherence tomography assessment in Stargardt disease
      Purpose Automated spectral domain optical coherence tomography (SD-OCT) segmentation algorithms currently do not perform well in segmenting individual intraretinal layers in eyes with Stargardt disease (STGD). We compared selective B-scan segmentation strategies for generating mean retinal layer thickness and preserved area data from SD-OCT scans in patients with STGD1. Methods Forty-five eyes from 40 Stargardt patients were randomly selected from the ongoing Natural History of the Progression of Atrophy Secondary ...
