Abstract
Purpose :
To evaluate the clnical utility and feasibility of a novel scanning laser ophthalmoscope based ultra wide field navigated optical coherence tomography (OCT) imaging system.
Methods :
Ultra-widefield navigated OCT images were captured using a modified Optos P200TxE that produced high-resolution OCT images of the retina targeted to a specific peripheral pathology with up to a 200° field. Images were obtained on patients with a variety of retinal conditions to assess utility of this imaging technique for diagnostic purposes and disease treatment decision making and monitoring.
Results :
Ultra-widefield navigated OCT images were obtained on 72 eyes of 59 patients. The average age was 58.8 ± 17.7 years, with a range from 8 to 86 years old. The most common pathology were retinoschisis (15 eyes), chorioretinal scars (15 eyes), peripheral drusen (11 eyes), retinal detachments (8 eyes), retinal holes (6 eyes), lattice degeneraion (4 eyes) and choroidal nevo (3 eyes). In 18 eyes, these images were clinically significant to monitor pathology more closely and with serial images. In 8 eyes images were clinically significant to confirm and proceed with treatment including laser, injections or surgery. These eyes included retinal detachments combined with schisis, retinal holes with overlying vitreal traction and subretinal fluid, focal vitreal activity and inflammation overlying a peripheral CMV retinal lesion and combined mechanism retinal detachments over focal peripheral neovascular membranes in Coats and sickle cell patients. In all 72 eyes high resolution ultra wide OCT images were successfully obtained with sufficient detail to manage peripheral pathology.
Conclusions :
Ultra widefield scanning laser ophthalmoscope navigated OCT imaging was clinically practical and provided detailed images of the peripheral preretinal, retinal and choroidal structures in our study of 72 eyes with peripheral pathology. It provided more information and was used to guide treatment and management of some cases. Future studies will be needed to refine the clinical utility and value of this imaging modality and its significane on peripheral pathology including help in diagnosis, monitoring and treatment of peripheral pathology.
