#Lattice degeneration icd10 series#

This was a retrospective, observational, consecutive case series conducted in an institutional setting. In the current study, we investigated whether this device could obtain the OCT images of the peripheral retinal degenerations and/or retinal breaks, and the frequency of inverted artifacts on the OCT images and the relationship with the location of retinal degenerations or axial length were also investigated. Since this device can also be photographed with only the basic technology, the spread of this device will make it easier to capture the tomographic images in the retinal periphery, and its evaluation will be useful for clinicians. This device produces an initial high-resolution UWF-SLO fundus image of up to 200° and uses navigated SSOCT line or volume scans at any location as mapped by UWF-SLO fundus images, which enables to expand the previously limited imaging range to the outermost part of the retina. Recently, another device that combines UWF-scanning laser ophthalmoscope (SLO) with a navigated SSOCT (Silverstone, Nikon Healthcare Japan, Inc, Tokyo, Japan) has become commercially available. 7 Mirror artifacts (inverted artifacts) are often detected in myopic eyes or in the peripheral part of nonmyopic eyes due to the scleral curvature, 6, 7 although they only occur from the Fourier transformation used in OCT systems, including spectral-domain and SSOCT. 6, 7 Of the OCT artifacts, it has been reported that the peripheral part of the OCT image is partially inverted in some cases, 6 which is called as a mirror artifact 6, 7 or an inverted artifact. It is well known that there are various artifacts in OCT image scans. 4, 5 However, it is still difficult to capture OCT images of the far-peripheral part of the retina. Recently, wide angle swept-source OCT (SSOCT) (Plex Elite 9000, Carl Zeiss Meditec, Dublin, CA) has been able to assess the mid-peripheral retinal structure and blood flow in various eye diseases. 2, 3 Previously, the imaging range of OCT was limited to the posterior pole of the fundus, but it is gradually expanding. Many important vitreoretinal abnormalities encountered in vitreoretinal care are located in the retinal periphery, identifiable on skilled peripheral retinal examination using indirect and/or direct fundus ophthalmoscopy, or more recently with the use of 2-dimensional ultra-widefield (UWF) imaging. To date, OCT has been widely used not only for retinochoroidal lesions but also for ophthalmic medical care in general, and becomes an indispensable device in ophthalmic medical care.

1 Since the first commercialization of optical coherence tomography (OCT) in 1996, it has played a major role in the evaluation and treatment of retinal diseases centered on the macula. Huang and Fujimoto et al succeeded in drawing a tomographic image of the retina and reported it to Science journal in 1991.
