    1. Anterior Segment OCTA of Melanocytic Lesions of the Conjunctiva and Iris

      Anterior Segment OCTA of Melanocytic Lesions of the Conjunctiva and Iris

      Purpose To study the feasibility and diagnostic value of vascular imaging using OCT-Angiography (OCTA) of melanocytic lesions of the conjunctiva and iris. Design; Cross-sectional study. Methods Twenty-five patients with an untreated conjunctival lesion (5 melanoma, 13 nevus, 7 primary acquired melanosis (PAM) and 52 patients with an untreated iris lesion (10 melanoma, 42 nevus) were included. Patients were imaged using a commercially-available OCTA device, with addition of an anterior segment lens and manual focussing. Tumor vessel presence, vascular patterns and vascular density were assessed. Results Good OCTA images were obtained in 18/25 conjunctival lesions, and 42/52 iris lesions ...

    2. Differences between Scheimpflug and optical coherence tomography in determining safety distances in eyes with an iris-fixating phakic intraocular lens

      Differences between Scheimpflug and optical coherence tomography in determining safety distances in eyes with an iris-fixating phakic intraocular lens

      Purpose To investigate the agreement and reliability of anterior segment optical coherence tomography (AS-OCT) and Scheimpflug imaging in measuring the distance from the anterior edge of an iris-fixated phakic intraocular lens (IF-pIOL) to the corneal endothelium. Methods Anterior segment configuration was assessed in a total of 62 eyes of which 25 hyperopic and 37 myopic eyes, all corrected with an IF-pIOL. Measurements were performed by two independent observers using AS-OCT (Visante, Model 1000, Carl Zeiss Meditec Inc.) and Scheimpflug imaging (Pentacam HR, Oculus Optikgerate). The distance from the anterior edge of the pIOL to the endothelium was measured in five ...
