Optical coherence tomography (OCT) is a new, noninvasive imaging technology for the evaluation of superficial lesions. Because of a penetrating depth of a few millimeters and an ultrahigh tissue resolution, it qualifies for use in the larynx and might in the near future play an important role in the pre-, intra-, and postoperative investigation of early laryngeal cancer and its precursor lesions. Especially directed to otolaryngologists, this paper describes the technique of in vivo OCT imaging of the larynx in detail during microlaryngoscopy and supplies a number of personal hints.

Ruthenium-106 brachytherapy and central uveal melanoma.

Department of Ophthalmology, Staedtisches Klinikum Dessau, Brandenburg Medical School Theodor Fontane, Dessau, Germany.
Purpose: Uveal melanoma (UM) is the most common primary ocular malignancy. The size and location of the tumor are decisive for brachytherapy with the β-emitting ruthenium-106 (Ru-106) plaque. The treatment of juxtapapillary and juxtafoveolar UM may be challenging because of the proximity or involvement of the macula and optic nerve and high recurrence rates.

: This study aimed to assess the role of macular pigment optical density (MPOD) in patients with a full-thickness macular hole (FTMH) compared to healthy controls, evaluating postoperative changes in MPOD and exploring potential correlations with visual outcomes. : This prospective, cross-sectional, comparative study included 16 eyes from FTMH patients who achieved anatomical hole closure following pars plana vitrectomy with the inverted ILM flap technique. Each eye underwent a comprehensive ophthalmologic examination, including BCVA and intraocular pressure measurements, anterior segment evaluation, fundus examination, and macular assessment with Enhanced Depth Imaging Optical Coherence Tomography (EDI-OCT, Spectralis, Heidelberg Engineering Inc.

The aim of this retrospective study was to compare corneal parameters and compliance using a Pentacam HR-Scheimpflug (Pentacam HR) and a swept-source OCT Casia (Casia) in keratoconus (KC) patients post penetrating keratoplasty (PKP) and KC patients without PKP, as well as a control group. Pachymetry measurements were also analyzed using a spectral domain OCT Solix (OCT Solix), Pentacam HR, and Casia. The study included 71 patients (136 keratoconic eyes; group A), 86 eyes with KC post-PKP (group B), 50 eyes with KC without PKP (group C), and 52 control participants (104 eyes).

Diabetic macular edema (DME) is a significant cause of vision loss. The development of peripheral non-perfusion (PNP) might be associated with the natural course, severity, and treatment of DME. The present study seeks to understand the predictive power of central macular changes and clinico-demographic features for PNP in patients with clinically significant DME.

This paper proposes and implements a novel scheme for recording signals from fibre optic sensors based on tandem low-coherence interferometry with an integrated optical reference interferometer. The circuit allows precision control of the phase shift. Additionally, the paper illustrates the potential for detecting vibration and object deformation using fibre optic Fabry-Perot sensors connected to the registration system.
