Normal Values of Corneal Optical Densitometry Using Pentacam Scheimpflug Camera
Cornea is unique to its transparency. It has Peculiar feature of transmitting almost all the light passing through it. Corneal clarity dwindles with surgical or pathological insults i.e. infections, corneal dystrophies and degenerations [1]. This induced corneal haze impedes the light rays to pass which results in backward scattering of light [2]. Maintaining regular surveillance over resulting...
متن کاملlens densitometry changes after corneal collagen cross-linking in patients with keratoconus using pentacam scheimpflug camera
purpose: to evaluate densitometry of crystalline lens after cxl procedure in keratoconic patients. methods: in a quasi-experimental study three-dimensional lens densitometry was performed by pentacam scheimpflug camera at base line and 6 months later. subject group contained patients with diagnosed progressive keratoconus who underwent cxl surgery (n = 40). control group contained aged-matched ...
متن کاملComparison of preoperative and postoperative anterior segment measurements with Pentacam in horizontal muscle surgery.
PURPOSE To evaluate the effect of horizontal muscle surgery (recession or recession plus resection) on the anterior chamber parameters in patients after strabismus surgery. METHODS The Scheimpflug of 18 eyes of 12 patients with horizontal deviations were recorded just before surgery and 1 month after surgery. The power of anterior surface of cornea in horizontal and vertical axis, thinnest co...
متن کاملComparison between Two Scheimpflug Anterior Segment Analyzers
PURPOSE To compare the anterior segment indices measured by two Scheimpflug camera machines; Galilei and Pentacam. METHODS In this observational case series, the anterior segment indices of myopic healthy subjects seeking for refractive surgery were measured by Pentacam and Galilei on the same day. Analyzed parameters were anterior and posterior best fit spheres (BFS), axial curvature, true c...
متن کاملPentacam: Principle and Clinical Applications
Rotating Scheimpflug imaging technology is used by instruments such as the Pentacam (Oculus) to measure the anterior and posterior corneal surfaces, as well as other anterior segment structures. Initially, Scheimpflug photography was used to obtain images of lens opacities for objective evaluation, but Pentacam-Scheimpflug camera is much wider in its clinical applications as a diagnostic tool f...
