During the past decade, noninvasive imaging has emerged as a valuable tool in clinical dermatology and dermatologic research. Optical coherence tomography (OCT) is one such type of noninvasive imaging. OCT uses the principle of interferometry to produce real-time images. A low-power diode laser shines infrared light onto tissues, which reflects back to an optical fiber interferometer. Using time delay and the backscattered light intensity, a two-dimensional image akin to an ultrasound is rendered. We review the history, types, and modalities of OCT, plus the many applications of frequency domain, high definition, and dynamic OCT in practice, including its utility in diagnosis, monitoring, and grading disease severity in a variety of cutaneous conditions.

Objective: Imaging techniques have demonstrated changes in the choroid and retina in acute central serous chorioretinopathy (CSCR), but the effects on the optic nerve head (ONH) remain unclear. This study investigates ONH structural changes in acute CSCR using enhanced deep imaging optic coherence tomography (EDI-OCT).
Methods: A prospective cohort study included 51 acute CSCR patients and 51 healthy controls aged 18-65 years.

Myopia is rapidly escalating globally, especially in East and Southeast Asia, where its prevalence among younger populations reaches alarming levels of 80 to 90%. This surge contributes to a myopia epidemic linked to several ocular complications, including glaucoma. As myopic individuals age, the risk of developing glaucoma increases, and an additional concern arises from the growing frequency of refractive surgeries among younger individuals, making precise optic nerve assessments critical before surgery.

Modeling Optical Coherence Tomography (OCT) images is crucial for numerous image processing applications and aids ophthalmologists in the early detection of macular abnormalities. Sparse representation-based models, particularly dictionary learning (DL), play a pivotal role in image modeling. Traditional DL methods often transform higher-order tensors into vectors and then aggregate them into a matrix, which overlooks the inherent multi-dimensional structure of the data.

January 2025
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.
