Objective:
To present in vivo imaging of leukocyte trafficking in retinal disease using adaptive optics scanning laser ophthalmoscopy (AOSLO).
Key Findings:
- Leukocyte activity was more frequently observed in venules than arterioles, with a 10:1 difference.
- Distinct leukocyte movement patterns included movement with and against flow, backtracking, and lateral migration.
- In diabetic retinopathy, leukocyte stalling and adhesion were noted near nonperfusion areas.
- Sickle cell disease showed adhesion and occlusive behavior, along with evidence of transmigration.
- In uveitis, increased extravascular leukocyte activity was observed.
Interpretation:
Visualizing leukocyte dynamics in vivo enhances understanding of immune responses in retinal diseases and may inform therapeutic strategies.
Limitations:
- Study involved a small sample size.
- Further research is needed to clarify the significance of observed changes post anti-VEGF therapy.
Conclusion:
AOSLO provides a dynamic view of leukocyte behavior in retinal diseases, potentially impacting disease understanding and treatment approaches.
