PurposeTo determine the relationship between different spectral domain optical coherence tomography (SD-OCT) signs of retinal ischemia in acute central retinal vein occlusion (CRVO) and whether they predict anterior segment neovascularization (ASNV).DesignRetrospective, observational study.SubjectsThirty-nine consecutive patients with acute CRVO and 12 months of follow-up.MethodsWe graded baseline SD-OCTs for increased reflectivity of the inner retina, loss of definition of inner retinal layers, presence of a prominent middle-limiting membrane (p-MLM) sign, and presence of paracentral acute middle maculopathy (PAMM). Graders were masked with respect to all clinical information.ResultsThe intraclass correlation coefficients (ICCs) of grading–regrading by graders 1 and 2 were 0.8104, 95% confidence interval (CI) (0.6686, 0.8956), and 0.7986, 95% CI (0.6475, 0.8892), respectively. The intragrader coefficients of repeatability (COR) for graders 1 and 2 were 0.94 and 0.92, respectively. The ICC of graders 1 compared with 2 was 0.8039, 95% CI (0.6544, 0.8916). The intergrader COR was 0.80. SD-OCT grades of baseline ischemia were not associated with baseline visual acuity (VA), central subfield mean thickness (CSMT), or relative afferent pupillary defect; 12-month VA, CSMT, change in VA, change in CSMT, number of antivascular endothelial growth factor injections or corticosteroid injections, or proportion of eyes developing ASNV. SD-OCT grades of ischemia did not correlate with the proportion of eyes having the p-MLM sign or PAMM. PAMM and p-MLM are milder signs of ischemia than increased reflectivity of the inner retinal layers. Eyes with PAMM can evolve, losing PAMM and gaining the p-MLM sign.ConclusionGrading of ischemia from SD-OCT in acute CRVO was repeatable within graders and reproducible across graders for the graders in this study. SD-OCT signs of ischemia are not correlated with each other and do not reliably predict subsequent ASNV. Close monitoring of eyes with acute CRVO continues to be the safest method to avoid missing ASNV and neovascular glaucoma.
