Specifically, the morphologic optical coherence tomography feature that is related to a better best-corrected visual acuity in congenital aniridia patients is the presence of outer segment lengthening. Computerized Macular Pathology Diagnosis in Spectral Domain Optical Coherence Tomography.pdf (973.4Kb) Date 2011-10. Conclusion: Foveal hypoplasia morphology can predict the best-corrected visual acuity. Computerized Macular Pathology Diagnosis in Spectral Domain Optical Coherence Tomography Scans Based on Multiscale Texture and Shape Features. Conversion Equation for Spectral-Domain Optical Coherence Tomography in an. The presence of outer segment lengthening was associated with better best-corrected visual acuity with a median best-corrected visual acuity, 0.30 logMAR, whereas the absence of this morphologic feature was associated with poorer VA with a median best-corrected visual acuity of 0.61 logMAR (p < 0.001). committed to expanding the reach of the department across all domains. Results: No correlation between central, mid-peripheral, and peripheral macular thickness and logMAR best-corrected visual acuity was found. Optical coherence tomography (OCT) uses low-coherence interferometery to obtain cross-sectional images of ocular structures such as the retina, optic nerve. A morphological grading system of foveal hypoplasia was used varying from grade 1 in which there is a presence of a shallow foveal pit, extrusion of inner retinal layers, outer nuclear layer widening, and a presence of outer segment lengthening to grade 4 in which none of these processes occur. PURPOSE: To characterize the features of peripapillary atrophy (PPA), as imaged by spectral-domain optical coherence tomography (SD-OCT). After a complete ophthalmological examination, a high-resolution spectral-domain optical coherence tomography with a three-dimensional scan program macular protocol was used. It uses a long-wavelength (near-infrared), broad-bandwidth light source to illuminate the retina and assess the light reflected from retinal tissue interfaces using a spectrometer and Fourier transformation. A total of 31 eyes from 19 patients with congenital aniridia were included. SD-OCT provides two- and three-dimensional images with nearcellular resolution (<10 m). Methods: Observational two-center study performed between January 2012 and March 2017 in the pediatric ophthalmology department at Vissum Alicante and Vissum Madrid, Spain. A new generation spectral domain optical coherence tomography (SD-OCT) technology has now been developed, representing a quantum leap in resolution and speed, achieving in vivo optical biopsy. The purpose of this study was to analyze whether the foveal morphology assessed by spectral-domain optical coherence tomography may serve as a prognostic indicator for best-corrected visual acuity in congenital aniridia patients. Background: Patients with congenital aniridia usually have some degree of foveal hypoplasia, thus representing a limiting factor in the final visual acuity achieved by these patients.
