| Titel | Comparing Ultrasound Biomicroscopy (UBM) and Anterior Segment Optical Coherence Tomography (AS-OCT) for imaging conjunctival nevi |
| Abstract Nr. | 2030 |
| Doel | To compare UBM and AS-OCT in the evaluation of conjunctival nevi. |
| Methodes | Prospective, observational, non-randomized trial. We examined 16 eyes of 15 consecutive patients with conjunctival nevi. |
| Resultaten | The visualization of the margins of the nevus was categorized as good, fair or poor. There was a good resolution in 100% of anterior margins for both UBM and AS-OCT cases. On UBM and AS-OCT the posterior margin had a good or fair resolution in 100% and 81%, respectively. Except for 1 UBM image and 1 AS-OCT image, all AS-OCT and UBM images had a good or fair resolution of the lateral margins. AS-OCT was able to visualize the nevi with a better resolution than UBM. Some degree of deep optical shadowing was seen on all AS-OCT images, but it only hindered good visualization of the posterior margin in 3 cases. Intrinsic cysts were seen in 6 cases (36%) with UBM and in 13 cases (81%) with AS-OCT, not necessarily in the same cases. |
| Conclusie | UBM and AS-OCT have the ability to accurately visualize the anterior and posterior margins although AS-OCT is more accurate in visualizing details. AS-OCT is more patient friendly but it has the disadvantage of deep optical shadowing, especially in thick nevi. We would advise to document conjunctival nevi with photographs and AS-OCT first and to use UBM only when the nevus is too thick to visualize the posterior margin with AS-OCT. |
