Herpetic Anterior Uveitis - Analysis of Presumed and PCR Proven Cases.Ocul Immunol Inflamm. 2019; 27(2):211-218.OI
To describe the demographics and clinical characteristics of patients with herpetic anterior uveitis (HAU), and compare characteristics by pathogen, recurrence, and association to iris atrophy.
Multicenter, retrospective study of AU patients diagnosed clinically and by polymerase chain reaction (PCR).
The study included 112 eyes in 109 patients: 54 (48.2%) HSV, 34 (30.4%) VZV, 2 (1.8%) CMV, and 22 (19.6%) unspecified diagnosis. HSV eyes, compared to VZV, had a higher recurrence rate, corneal involvement, KPs, iris atrophy, elevated IOP and posterior synechia (p < 0.05). VZV patients had more frequent immunomodulatory treatments and history of systemic herpetic disease (p < 0.05). Fifty-nine (52.7%) eyes had recurrent disease. Iris atrophy was associated with a higher prevalence of posterior synechia, dilated distorted pupil, and high IOP (p < 0.05).
Different HAU-causing Herpesviridae produce common clinical findings; therefore, PCR should be used more often to confirm specific diagnosis. Iris atrophy was associated with more severe disease.
