Visualization of the left fundus was precluded by 4+ vitreous cell
Anterior chamber examination was unremarkable and trace vitreous cell
was noted in both eyes.
Corneal edema, anterior chamber and vitreous cells
, and retinal hemorrhages resolved, but the optic nerve was pale and retinal neovascularization developed (Figure 2B).
Ophthalmic examination of PVRL typically reveals mild anterior chamber cells and more prominent vitreous cells
with floating clumps.
Another theory attributes the pathogenesis of an ERM to the growth and fibrous metaplasia of the vitreous cells
that remain on the retina surface after posterior vitreous detachment.
Funduscopic examination of the right eye revealed vitreous cells
and 1+ vitreous haze, grade 2 disc edema, two patches of active retinitis in the inferior periphery, and pigmentary changes superiorly.
Any mentioned inflammatory sign (i.e., anterior chamber cell > 0.5+, vitreous cells
> 0.5+, active retinal vasculitis, or active chorioretinal lesions) was enough to be eligible.
Clinical assessment shows telangiectatic vessels, 'light-bulb' aneurysms, capillary dropout, massive retinal exudation, vitreous cells
and scarring (Figure 3).
However, the presence of bilateral vitreous cells
raised the possibility of influenza retinopathy (7).
There were vitreous cells
in the left eye; however, the optic nerve, macula, and the peripheral retina seemed normal.
Moreover, the disease activity was defined as cells and flare in the anterior chamber, vitreous cells
, retinal perivascular sheathing, retinal infiltration, new retinal hemorrhages, or optic papillitis, according to the Standardization of Uveitis Nomenclature (SUN) Working Group terminology .
In the presence of vitreous cells
(seen on slit lamp biomicroscopy immediately behind the lens), this series of symptoms should raise the possibility of a diagnosis of a posterior uveitis (such as Birdshot Chorioretinopathy).
