研究目的
To describe an imaging finding seen on optical coherence tomography (OCT) of patients with vitreoretinal lymphoma.
研究成果
Vertical hyperreflective lesions are a common physical finding on OCT in eyes with vitreoretinal lymphoma and may suggest the diagnosis of vitreoretinal lymphoma and provide clues as to its pathogenesis.
研究不足
The study's retrospective nature and the limited number of imaging studies performed. In some patients, only OCT scans centered on the fovea were performed, potentially missing peripheral lesions. Fundus autofluorescence was often not gradable due to bad image quality in the setting of vitreous infiltration. None of the patients underwent OCT angiography examinations.
1:Experimental Design and Method Selection:
A retrospective medical record review of patients diagnosed with vitreoretinal lymphoma at the Department of Ophthalmology at Northwestern University between July 2014 and January
2:Sample Selection and Data Sources:
20 Patients with a diagnosis of intraocular lymphoma seen by two senior attending physicians were identified using electronic medical records. Exclusion criteria were an uncertain diagnosis and inadequate OCT image quality.
3:List of Experimental Equipment and Materials:
Spectralis OCT (Heidelberg Engineering) for OCT examinations, Adobe Photoshop (version 13.0.1 CS6 Extended; Adobe Systems Inc) for image analysis.
4:1 CS6 Extended; Adobe Systems Inc) for image analysis. Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: OCT examinations were conducted with a raster scan covering the whole macular region (30° × 25°), and in some cases, additional scans were centered on the temporal retina or the temporal vascular arcades. The standard scanning pattern consisted of 61 scans (with one exception of 121 scans) and an Automatic Real-time Tracking setting between 9 and
5:Data Analysis Methods:
Color photos, fundus autofluorescence, and infrared reflectance images were analyzed using Adobe Photoshop.
