Nowadays, several devices offer distinct methods for acquiring short-wave fundus autofluorescence (SW-FAF) images, all of them being clinically useful in assessing the presence of lipofuscin, a naturally occurring ocular fluorophor which reflects the general health of the photoreceptor and retinal pigment epithelium (RPE). Each device provides a different image acquisition method; thus, discrepancies exist in the images obtained. For example, fundus cameras feature a high-energy white flash that streams through a wideband excitation filter and a series of mirrors and apertures to obtain images. On the other hand, confocal scanning laser ophthalmoscope (cSLO) emits a single wavelength, which will only excite fluorophores that absorb light with a peak excitation near that specific wavelength [2]. Broad line fundus image (BLFI) technique is a hybrid of both cSLO and traditional fundus photography. By utilizing line scanning illuminationwith light-emitting diodes (LEDs) and an aperture confocal to the illumination, this system illuminates and detects retinal images in two wavelength ranges: fundus autofluorescence (FAF)-Blue (435–500 nm) and FAF-Green (500–585 nm) [3]. Both are categorized as short-wavelength, but it is well known that green light can reach deeper layers of the retina, being absorbed less by the luteal pigments of themacula, and allowing a better definition of lesions in the underlying RPE. ONHD are a form of calcific degeneration in some of the axons of the optic nerve that may give a swollen-looking appearance, and are usually formed early in life. ONHD are diagnosed with fundoscopic examination, but some casesmay require B-scan ultrasonography, AF, and optical coherence tomography (OCT) to confirm the lesion [4]. The features of ONHD in FAF imaging are well described in many previous publications [4], [5]. Yan et al. [4] recently described the peculiarities of ONHD in FAF-Blue and -Green by using a cSLO system from two different devices. Despite a considerable amount of meaningful information, we were unable to find a description of FAF imaging in ONHD using BLFI technology in the literature. We have recently observed a noticeable disparity in the","PeriodicalId":73178,"journal":{"name":"GMS ophthalmology cases","volume":"13 ","pages":"Doc14"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10413383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10000996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
