To determine if Retcam is a useful tool in imaging the anteriorchamber angle (ACA).
This is a retrospective non-comparative case series of 15 patients(24 eyes) who underwent imaging of their ACA with the RetCamII wide-field digital paediatric retinal imaging device (ClarityMedical Systems, Inc.CA) between 6th May 2009 and 18th November2009. The four quadrants of the ACA were imaged with the subjectsin a semi-supine position and the operator at the head end.The 130o widefundus lens was attached to the camera with acable connected to a computer monitor. A topical anaesthetic(tetracaine hydrochloride 0.5%) was instilled in the eye, followedby an application of coupling gel on the cornea.The tip of thelens was immersed in the gel at the limbus and directed towardsthe opposite side of the angle to be imaged. The illuminationand focus of the image was adjusted to obtain the ACA image.
We selected 5 out of 15 patients who had their ACA imaged usingthe RetCam. The images were graded according to the Shaffer'sgrading system. Figure 1 to 5 shows grade 0 to 4 angle respectively.
This new novel application of the RetCam produces dynamic imagesof the angle structures.
