It can also be used for imaging in adult patients with poor posture or spinal deformities. It can be used as a diagnostic and prognostic tool, with the ability to assess the development of the pediatric eye. It makes pediatric imaging more accessible and enables non-invasive monitoring. Mervyn Thomas, NIHR Academic Clinical Lecturer, hand-held OCT has numerous clinical benefits. Hand-held OCT delivers retinal architecture data at unprecedented levels.Īccording to Dr. The launch of the Leica Envisu C2300 system helped address this unmet clinical need, revolutionizing pediatric ophthalmology. Solutions such as RetCam allow ultra-widefield (UWF) retinal imaging but do not provide ultrastructural data. Performing retinal imaging in a baby can be difficult with classical table-mounted OCT. Hand-held OCT can be used with lenses to acquire images of the anterior and posterior segment. This makes it very easy to perform a scan, on both adults and children. It can be used everywhere, including in the operating theater. One of the big advantages of hand-held OCT is that it is portable. As such, the Ulverscroft Eye Unit essentially relies on caliper measurements with comparisons based on published data. However, while it provides high-quality scans, hand-held OCT does have some limitations: there is no fixation target, no eye tracking allowing averaging and no automatic segmentation. They both have microscopic resolution, in the range of research imaging technology. Frank Proudlock, Associate Professor of Ophthalmology and Ulverscroft Eye Unit team manager, points out: “Hand-held OCT has more applicability than just using it on children”.īoth conventional OCT and hand-held OCT are spectral-domain OCT, with very high sampling rates. Hand-held OCT makes it easier to examine children and infants.
