Pentacam scheimpflug system

Manufactured by Oculus

Sourced in Switzerland

The Pentacam Scheimpflug system is an advanced ophthalmic imaging device that provides detailed, high-resolution images of the anterior segment of the eye. The system utilizes the Scheimpflug principle to capture cross-sectional images of the cornea, iris, and lens, allowing for comprehensive analysis of the eye's structure and measurements.

This study adhered to a protocol approved by the Institutional Review Board of the Zhongshan Ophthalmic Center, Sun Yat-Sen University, following the Declaration of Helsinki. A total of 115 patients with congenital cataracts were included in the present study which is a part of the Childhood Cataract Program of the Chinese Ministry of Health (CCPMOH) [7 (link)]. The parents of the probands gave written informed consent before participating in the study. The clinical records of the proband were collected. Thorough ocular examinations were performed using slit-lamp photography (BX900; Haag-Streit, Bern, Switzerland), the Pentacam scheimpflug system (Oculus, Wetzlar, Germany), Tono-Pen (Reichert, Depew, NY, USA), A- and B-scan ultrasound (Aviso, Quantel Médical, Clermont-Ferrand, France), RetCam (Natus Medical Incorporated, Pleasanton, CA, USA), and optical coherence tomography (OCT; Cirrus HD-OCT 5000, Carl Zeiss Meditec, Dublin, CA, USA).

Clinical data of the patient were collected based on medical history review, clinical examinations of facial dysmorphia, head circumference, height, and thorough ocular examinations including slit-lamp photography (BX900; HAAG-STREIT AG, Bern, Switzerland), Pentacam scheimpflug system (Oculus, Wetzlar, Germany), Tono-Pen (Reichert, Inc., Depew, NY, USA), and visual evoked potential (RETeval, LKC Technologies, Inc., Gaithersburg, MD, USA), and A-scan ultrasound and B-scan ultrasound (Aviso, Quantel Médical, Clermont-Ferrand, France). The horizontal corneal diameter was measured by caliper.

Comprehensive Corneal Evaluation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

Subjects underwent an ophthalmic assessment. Habitual visual acuity was obtained using a standard Snellen chart. Slit-lamp biomicroscopy and optical coherence tomography of the anterior segment (Topcon 3D OCT2000, Topcon Corporation, Tokyo, Japan) were carried out to confirm ocular health of the anterior segment. Non-contact specular microscopy of the central cornea (Topcon SP2000, Topcon Corporation, Tokyo, Japan) was performed to rule out corneal endotheliopathy or any other notable corneal endothelial abnormalities. The anterior segment was then assessed using the Pentacam Scheimpflug system (Pentacam, Oculus GmbH, Wetzlar, Germany). Two Pentacam measurements of the same eye were performed, with the subjects being asked to blink and reposition between scans and with the automatic release mode used to minimise observer-related variability. Corneal thickness was extracted from topographic maps at 1 mm increments including the apex (central corneal thickness) and peripheral nasal and temporal locations up to 5 mm away from the apex at 11 locations along the horizontal corneal meridian. The mean corneal radius was recorded. The mean of two scans was used for analyses.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
