Abstract
Purpose
We sought to investigate and describe the clinical spectrum of posterior segment abnormalities in immunocompetent patients presenting with CMV-associated anterior uveitis.
Methods
This was a prospective study conducted at the Singapore National Eye Centre, a tertiary referral centre, from August 2010 to June 2011. Eleven eyes of eleven patients with CMV anterior uveitis confirmed by polymerase chain reaction on aqueous humor sampling were recruited based on the study criteria. Patients were recruited from a single uveitis specialist clinic and underwent aqueous humor sampling and fluorescein and indocyanine green angiography as well as optical coherence tomography. They were further evaluated by the Infectious Disease physician for immunocompetence.
Results
Mean presenting visual acuity was logMAR 0.35 ± 0.29. The main presenting complaints were blurring of vision, eye redness, and pain. Anterior chamber cellular activity was present in all cases. Fine diffuse keratic precipitates (KPs) were present in 10 eyes, and the remaining one eye had mutton fat KPs. Iris changes were present in three eyes. Intraocular pressure (IOP) was elevated in nine eyes (mean presenting IOP was 40.2 ± 16.8 mmHg). In the posterior segment, none of the eyes had evidence of retinitis or hemorrhage. Posterior segment abnormalities were present in six eyes (macular edema, disc leakage, epiretinal membrane, phlebitis). Eight eyes also had prolonged arm to retina time (mean 24.8 ± 10.6 s) on fluorescein angiography. Indocyanine green angiography was unremarkable.
Conclusion
Posterior segment manifestations can be seen in a proportion of immunocompetent patients with CMV anterior uveitis. The underlying mechanism remains to be determined.
