To present the initial results of imaging of healthy and diseased corneas and iridocorneal angle with a new anterior segment spectral optical coherence tomography (AS-SOCT) SOCT Anterius.
10 healthy individuals and 20 patients with corneal pathologies or narrow angle glaucoma were examined with SOCT Anterius (OPTOPOL Technology S.A., Zawiercie, Poland), a production prototype of a new anterior segment spectral optical coherence tomography. The studied group included cases of corneal scars, ulcers, various dystrophies, lamellar and penetrating corneal grafts and status post laser refractive surgery.The images of healthy corneas were confronted with histological specimens of healthy corneas from our archives.
Cross-section tomography images were acquired. It was possible to clearly distinguish corneal epithelium, Bowman’s layer and stroma and to measure the thickness of those layers. The iridocorneal angle structures were well-defined and measurements of angle width were possible. The corneal lesions (scars, ulcers, and dystrophic lesions) were imaged so they could be distinguished from surrounding tissue and their depth could be measured. It was possible to distinguish the interface of lamellar grafts and LASIK flap.
AS-SOCT is a noninvasive technique for cross-section imaging of the anterior segment of the eye. SOCT Anterius provides high resolution images, enabling sublayer pachymetry of healthy cornea and measuring the depth of various corneal lesions. Assessing of corneas after lamellar procedures including LASIK and lamellar grafts is possible and a range of other anterior segment measurements including iridocorneal angle width can be performed.
