NONINVASIVE GRADING OF RADIATION RETINOPATHY: The Use of Optical Coherence Tomography Angiography.
Retina (Philadelphia, Pa.)(2015)
摘要
PURPOSE:Previous studies have shown that spectral domain optical coherence tomography can diagnose radiation retinopathy (RR) before ophthalmoscopic findings. Recently, optical coherence tomography angiography (OCT-A) has been helpful in seeing vascular findings undetected by spectral domain optical coherence tomography. The authors wish to demonstrate the OCT-A grading at varying levels of RR.
METHODS:The OCT-A, spectral domain optical coherence tomography, and ophthalmoscopic findings on 7 patients from December 2014 to March 2015 with varying levels of RR are demonstrated.
RESULTS:Findings on OCT-A could be demonstrated before spectral domain optical coherence tomography findings. Patients can be graded on a scale of increasing severity from 0 to 5, based on positive or negative clinical findings of RR between OCT-A. Optical coherence tomography increased central macular thickness, optical coherence tomography evident cysts, and ophthalmoscopy (Grade 0: -,-,-,-; Grade 1: +,-,-,-; Grade 2: +,+,-,-; Grade 3: +,+,+,-; Grade 4: ++,+,+,+; Grade 5: unreadable,++,++,+).
CONCLUSION:The use of OCT-A allows for earlier detection of RR; thus, existing grading systems should be modified to include OCT-A.
