“…Ultraviolet (UV) light serves as a standard and extensively employed diagnostic tool for evaluating vitiligo. Among the reviewed studies, UV light was utilized as a diagnostic technique in seven studies, with Wood's lamp being the preferred choice in six of them (46)(47)(48)(49)(50)(51)55). The theory behind UV light photography suggests that UV rays are selectively absorbed by melanin in the epidermis compared to visible light.…”

“…Dermoscopy was utilized in eleven different studies (46,49,(55)(56)(57)(58)(59)(60)(61)(62)(63), of which two studies used ultraviolet light (46,49), and one used high dynamic range conversion of images for diagnostic and monitoring purposes (55). Perifollicular changes and interfollicular pigmentation constituted the most common dermoscopic observations seen by Al-Refu et al and Jha et al (56,57).…”

“…Perifollicular changes and interfollicular pigmentation constituted the most common dermoscopic observations seen by Al-Refu et al and Jha et al (56,57). Two studies showed that employing UV-dermoscopy can identify various distinctive microscopic characteristics of vitiligo not seen in polarized dermoscopy, namely, an enhanced perifollicular border and a more distinguishable depigmented junctional zone (46,49). Kaliyadan et al observed that prominent pigmentary features were perceived to show significant enrichments after HDR conversion (55).…”

Vitiligo is a multifaceted autoimmune depigmenting disorder affecting around 0.5 to 2.0% of individuals globally. Standardizing diagnosis and therapy tracking can be arduous, as numerous clinical evaluation methods are subject to interobserver variability and may not be validated. Therefore, there is a need for diagnostic tools that are objective, dependable, and preferably non-invasive.AimsThis systematic review provides a comprehensive overview of the non-invasive objective skin measurement methods that are currently used to evaluate the diagnosis, severity, and progression of vitiligo, as well as the advantages and limitations of each technique.MethodsThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was used for the systematic review. Scopus, Embase, Cochrane Library, and Web of Science databases were comprehensively searched for non-invasive imaging and biophysical skin measuring methods to diagnose, evaluate the severity of, or monitor the effects of vitiligo treatment. The risk of bias in included articles was assessed using the QUADAS-2 quality assessment scale.ResultsAn extensive literature search resulted in 64 studies for analysis, describing eight imaging techniques (reflectance confocal microscopy, computer-aided imaging analysis, optical coherence tomography, infrared photography, third-harmonic generation microscopy, multiphoton microscopy, ultraviolet light photography, and visible light/digital photograph), and three biophysical approaches (dermoscopy, colorimetry, spectrometry) used in diagnosing and assessing vitiligo. Pertinent information about functionality, mechanisms of action, sensitivity, and specificity was obtained for all studies, and insights into the strengths and limitations of each diagnostic technique were addressed. Methodological study quality was adequate; however, statistical analysis was not achievable because of the variety of methods evaluated and the non-standardized reporting of diagnostic accuracy results.ConclusionsThe results of this systematic review can enhance clinical practice and research by providing a comprehensive overview of the spectrum of non-invasive imaging and biophysical techniques in vitiligo assessment. Studies with larger sample sizes and sound methodology are required to develop verified methods for use in future practice and research.Systematic review registration(PROSPERO) database, (CRD42023395996).

“…It uses a specific wavelength light source to distinguish depth of pigmentation depending on different degrees of auto-fluorescence [4]. There are very few studies that have evaluated dermoscopic and Wood lamp findings for the diagnosis and classification of all facial melanoses [5]; some studies have only focused on melasma [6][7][8]. We therefore aimed to evaluate the dermoscopic findings of common facial melanoses and correlate them with findings from Wood lamp examination.…”

Introduction: Facial melanosis is one of the most common reasons for which patients refer to a dermatologist in Nepal. Objectives: The objective of this study was to evaluate the dermoscopic findings of common facial melanoses and correlate them with findings from Wood lamp examination. Methods: This was a cross-sectional study conducted at the Department of Dermatology and Venereology, Nepal Medical College and Teaching Hospital. We recruited a total of 204 patients from July 2020 to March 2021. The most common diagnosis was melasma (37 patients) followed by melasma with steroid-induced rosacea-like dermatitis (29 patients). After collecting clinical and demographic data, patients underwent Wood lamp and dermoscopic examination. Results: Dermoscopy of ashy dermatosis and nevus of Ota revealed blue-gray pigmentation forming a curvilinear pattern; café-au-lait macule and nevus spilus revealed a light brown reticular pattern with follicular sparing; and a reticular and hem-like pattern of pigmentation was observed in clofazimine-induced pigmentation, peribuccal pigmentation of Brocq and periorbital pigmentation. The degree of agreement between Wood lamp and dermoscopic findings was found to be statistically significant in melasma (κ = 0.701, P = 0.0001) and melasma with steroid-induced rosacea-like dermatitis (κ = 0.628, P = 0.0001). While the agreement between the two techniques was 100% for epidermal types, it decreased to 44.8% for dermal melasma and 61.5% for dermal melasma with steroid-induced rosacea-like dermatitis. Conclusions: Dermoscopy is useful in assessing facial melanoses. It may be supplemented with Wood lamp examination to increase diagnostic accuracy.
