Abstract

Purpose :
To evaluate vitreoretinal cellular infiltration in uveitis on spectral domain optical coherence tomography (SD-OCT) and to develop a new OCT-based grading system of severity of inflammation in uveitis.

Methods : In this retrospective study, 40 eyes from 26 patients with uveitis in posterior segment and 23 eyes with no apparent abnormalities from 23 persons as sex- and age-matched controls were enrolled. All subjects in this study were received detailed ophthalmic examinations including SD-OCT (Spectralis; Heidelberg Engineering, Heidelberg, Germany).
The SD-OCT cross-sectional images through fovea in all subjects were graded as follows: grade 0, no presence of cell-like hyper-reflective particle (CLHP); grade 1, several CLHPs (≦10 particles) on the retinal surface; grade 2, a small number of CLHPs (≦5 particles) in the vitreous and several CLHPs on the retinal surface.; grade 3, increased CLHPs in the vitreous; grade 4, a large number of CLHPs in the whole vitreous space. Reference images in the OCT-based grading were shown in figure.
The primary outcome measures were sensitivity and specificity of the ability of the grading system to differentiate uveitis. The secondary outcome measure was a correlation of the OCT-based grading with vitreous haze classification according to the SUN Working Group criteria. Inter-observer agreement was also evaluated.

Results :
The presence of vitreous CLHPs in SD-OCT was detected in 27 eyes (67.5%) in uveitis group, and detected in 2 eyes (8.7%) in control group. The sensitivity and specificity were 67.5% and 91.3%, respectively. The presence of inflammation using the OCT-based grading (≧grade 0.5) was detected in 34 eyes (85%) in uveitis group, and no one in control group, and the sensitivity and specificity were 85% and 100%, respectively. This OCT-based grading in uveitis was significantly correlated with the vitreous haze classification (R=0.403, p<0.01). The inter observer agreement of the presence or absence of inflammation using the OCT-based grading was excellent (κ= 0.84) and the inter observer agreement of the OCT-based grading score was moderate (κ= 0.5).

Conclusions :
This newly developed OCT-based grading in vitreoretinal cellular infiltration can provide a good sensitivity and specificity to differentiate uveitis in posterior segment and control subjects, and may be applicable in evaluating severity of vitreous haze.
