MULTICOLOR CONFOCAL SCANNING LASER OPHTHALMOSCOPE IMAGING IN POSTERIOR UVEITIS.

Purpose: To study the utility of MultiColor confocal scanning laser ophthalmoscope imaging (MCI) in identifying the morphology of uveitic lesions compared with conventional color fundus photography (CFP) in patients with posterior uveitis.

Methods: In this prospective observational study, subjects with posterior uveitis underwent MCI and CFP. The images obtained by the two modalities were analyzed by two independent reviewers for vitreoretinal surface abnormalities, retinal fluid and hemorrhages, and depth/location of lesions. These findings were compared with the clinical findings and other imaging techniques.

Results: Sixty-nine eyes of 43 patients (25 men) with mean age of 33.5 ± 13.9 years were studied. MultiColor imaging had better sensitivity and specificity in detecting vitreoretinal interface abnormalities, such as epiretinal membrane and inner retinal striae, compared with CFP. MultiColor imaging failed to detect retinochoroiditis lesions in 5 of 6 eyes (83%) and choroiditis in 9 46 eyes (20%), which were detected on CFP and clinical examination. Also, MCI showed a high false-positive rate of 34% in detecting intraretinal hemorrhages.

Conclusion: Retinochoroidal lesions in posterior uveitis may be poorly identified on MCI compared with CFP and clinical examination. One must exercise caution in commenting on disease morphology based on MCI alone.
