In OCT, the anatomic layers within the retina can be visualized and the thickness of the retina can be measured. This is an exceptional advancement in diagnostic imaging because it allows real-time visualization of the microstructure of a tissue without the need to excise and process a biopsy specimen. It is used both for diagnosis and to guide intervention.

Abstract: The correction of leg telangiectasias is one of the most frequently performed interventions in the Western world. While sclerotherapy remains the gold standard of treatment, several studies have shown comparable efficacy and, in some situations, an even more favorable use of lasers as an alternative treatment option. The most frequent side effect of both treatment options is hyperpigmentation, which usually clears spontaneously in most cases but can be challenging to treat if it persists. The origin of this hyperpigmentation is not fully understood; small studies point to hemosiderin as the causative pigment, at least in post-sclerotherapy hyperpigmentation. More rare side effects of the treatment include ulcerations and scarring. Quality-switched (QS) Nd:YAG lasers have demonstrated good efficacy in treating hemosiderin depositions in the skin, post-inflammatory hyperpigmentation and atrophic scars. We present a case of post-inflammatory hyperpigmentation and scarring after laser treatment of leg telangiectasia with a long-pulsed Nd:YAG laser that was successfully treated using a QS Nd:YAG 1064 nm laser. This case suggests the QS Nd:YAG laser as a possible treatment option in cases of hyperpigmentation with various origins, including hemosiderin and melanin, and scarring after laser treatment of leg telangiectasias.

Optical coherence tomography (OCT) is noninvasive, noncontact, imaging technique that can make images of structures in the retina with a resolution of 10 to 17 microns. Cross-sectional images of the retina in a fashion similar to ultrasound but at a much higher resolution and using light waves rather than sound waves.

OCT was first introduced in 1991[Huang, 1991] and has since been adapted to a number of clinical biomedical imaging settings including ophthalmology. Its largest ophthalmology impact has been the imaging of the retina.

Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research area. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal.

OCTeye test side effects

The OCT is useful in visualizing the pathology of many eye diseases including diabetic retinopathy, macular degeneration, macular holes, epiretinal membranes, macular edema, central serous choroidopathy and optic disc pits.
