The Quantification and Impact of Persistent Retinal Fluid Compartments on Best-Corrected Visual Acuity of Patients
Background And Objectives:
To evaluate the impact of persistent intraretinal fluid (IRF) and subretinal fluid (SRF) on best visual acuity (BVA) of patients with retinal vein occlusions (RVOs).
Patients And Methods:
This retrospective cohort study observed 92 treatment-naïve patients with RVO during 12 months of treatment with anti-vascular endothelial growth factor agents. Deep learning was used to quantify IRF and SRF volumes, and linear mixed effects regression modeled the impact on BVA.
Results:
Average IRF volume declined -923.1 ± 2,382.5 nL from baseline to 12 months (P < .001). Average SRF volume declined -35.4 ± 223.4 nL from baseline to 12 months (P = .139). linear mixed effects regression modeling disclosed IRF≥ 1,616 nL at all time points predicted a -10.38 letter loss at 12 months (95% CI, -14.58 to -5.9 letters; P < .001). A similar relationship was not found for SRF.
Conclusion:
Persistent IRF may be an important prognostic biomarker for BVA outcomes in real-world patients with RVO. [.
