Pentecam gives accurate measurements

The Pentecam is reliable in measuring superior and inferior anterior chamber angle (ACA) temporal and nasal ACA, anterior chamber volume (ACV) and anterior chamber depth (ACD).

The Pentecam is reliable in measuring superior and inferior anterior chamber angle (ACA) temporal and nasal ACA, anterior chamber volume (ACV) and anterior chamber depth (ACD).

Dr Gemma C.M. Rossi et al., University Eye Clinic of Pavia, IRCCS Policlinico San Matteo Foundation, Pavia, Italy, completed an observational, single-centre, cross-sectional investigation on 28 eyes with primary narrow-angle or primary angle-closure glaucoma and 36 controls.

All patients underwent gonioscopy and measurements for ACA, ACV and ACD. Receiver operating characteristics (ROC) curves analysis was used to assess the validity of Pentecam parameters.

According to the ROC analysis, there was a high discriminate power for all Pentecam measures and the chosen cutoff values enabled the correct identification of narrow angles.

Overall, the Pentecam is efficient in detecting occludable angles it is non-contact, meaning it provides parameters in a short time period, representing a possible screening tool.
