Standardized baseline human corneal subbasal nerve density for clinical investigations with laser-scanning in vivo confocal microscopy.
PURPOSE We established a baseline value for central corneal subbasal nerve density in a large, healthy cohort. METHODS A total of 106 healthy volunteers (207 eyes) underwent full ophthalmic examination, including laser-scanning in vivo confocal microscopy (IVCM) of the central cornea. Images of the corneal subbasal nerve plexus were acquired and analyzed based on defined criteria. Nerve traci...
متن کاملMorphometric stability of the corneal subbasal nerve plexus in healthy individuals: a 3-year longitudinal study using corneal confocal microscopy.
PURPOSE We examined the age-dependent alterations and longitudinal course of subbasal nerve plexus (SNP) morphology in healthy individuals. METHODS Laser-scanning corneal confocal microscopy, ocular screening, and health and metabolic assessment were performed on 64 healthy participants at baseline and at 12-month intervals for 3 years. At each annual visit, eight central corneal images of th...
متن کاملSubbasal nerve density and corneal sensitivity after laser in situ keratomileusis: femtosecond laser vs mechanical microkeratome.
OBJECTIVE To compare changes in subbasal nerve density and corneal sensitivity after laser in situ keratomileusis (LASIK) with the flap created by a femtosecond laser (bladeless) vs a mechanical microkeratome. DESIGN In a randomized paired-eye study, 21 patients received myopic LASIK with the flap created by a femtosecond laser in one eye and by a mechanical microkeratome in the fellow eye. E...
متن کاملTwo-Dimensional Plane for Multi-Scale Quantification of Corneal Subbasal Nerve Tortuosity
PURPOSE To assess the performance of a novel system for automated tortuosity estimation and interpretation. METHODS A supervised strategy (driven by observers' grading) was employed to automatically identify the combination of tortuosity measures (i.e., tortuosity representation) leading to the best agreement with the observers. We investigated 18 tortuosity measures including curvature and d...
متن کاملCorneal sensation and subbasal nerve alterations in patients with herpes simplex keratitis: an in vivo confocal microscopy study.
PURPOSE To study and correlate corneal sensation in patients with herpes simplex keratitis (HSK) with density and morphologic features of subbasal corneal nerves by in vivo confocal microscopy (IVCM). DESIGN Prospective, cross-sectional, controlled, single-center study. PARTICIPANTS Thirty-one eyes with the diagnosis of acute (n = 7) or chronic (n = 24) HSK and their contralateral clinicall...
