Abstract
Purpose :
Assess the real-world clinical benefits of a new ultra widefield (UWF) swept-source (SS) 200 KHz single-scan 26 mm X 12 mm capturing window OCT imaging technology allowing core and cortical vitreous, vitreoretinal interface as well as posterior pole and navigated mid and peripheral retinal imaging.
Methods :
Retrospective observational study. One hundred and sixty eyes (80 patients) were imaged using both 200° multi wavelength UWF red/green (RG), infrared (IR), and fundus autofluorescence (FA) imaging (Optos Silverstone (Optos PLC, Dunfermline, UK) and a novel 130° single-scan UWF SS OCT with 26mm scan length and 12 mm imaging window depth (DREAM OCT®, IntaLight, China).
Results :
Retinal image diagnosis included findings in the posterior pole, mid-periphery and periphery.
Anatomical changes in the cortical vitreous and vitreoretinal interface were successfully imaged in 160 eyes (100 %). Vitreous image diagnosis included vitreous floaters and opacities (VFO), Weiss ring, synchysis, incomplete and complete vitreous detachment, vitreo-macular traction, and residual cortical vitreous following selective vitrectomy for the treatment of symptomatic VFO.
Anatomical changes in the posterior pole and mid-peripheral retina were successfully imaged in 160 eyes (100 %). Retinal image diagnosis included intra and subretinal fluid, pigment epithelium detachments. serous detachments, choroidal thickness changes, macular epiretinal membrane, macular and peri optic nerve head myopic schisis, staphyloma, dome-shaped macula, lattice degeneration, retinal holes and tears.
Anatomical changes in the peripheral retina were successfully imaged in 150 eyes (94 %). Retinal image diagnosis included lattice degeneration, retinal holes and tears, sudretinal fluid, subclinical retinal detachment, vitreous attachment and traction, and retinoschisis.
Conclusions :
This novel 130° single-scan UWF SS OCT with 26mm scan length and 12 mm imaging window depth technology allowed for wider and deeper scans that were clinically meaningful and of adequate resolution that significantly contributed to diagnosis and treatment strategy.
