Purpose: Vogt-Koyanagi-Harada (VKH) syndrome is a systemic inflammatory autoimmune disease with associated ophthalmic pathology. Glaucoma has been reported in patients with VKH. The purpose of this report is to examine the frequency and types of glaucoma associated with VKH.Methods: This was a retrospective case series. Electronic medical records of patients with VKH were reviewed from two medical centers: Duke University and the University of North Carolina.Results: Of 45 eyes with VKH, 28 (62%) developed ocular hypertension (OHT) or glaucoma. In the patients with VKH and OHT/glaucoma, 18/28 (64%) had posterior synechiae and/or peripheral anterior synechiae.Conclusions: We have shown a high prevalence of OHT and glaucoma in eyes with VKH. Furthermore, in addition to secondary open angle from corticosteroid treatment and uveitis, secondary angle closure resulting from posterior synechiae, frequently associated with iris bombé configuration, is an important cause of glaucoma in VKH eyes.

Purpose: The aim of this study was to evaluate the retinal nerve fiber layer (RNFL) thickness in vernal keratoconjunctivitis (VKC) patients who were under long-term topical corticosteroid therapy. Methods: Thirty-six eyes of 36 VKC patients with clear cornea and normal videokeratography and 40 eyes of 40 age- and gender-matched normal children were included in the study. Clinical and demographic characteristics of the patients were noted and detailed ophthalmological examination was performed. Visual acuity (VA), spherical equivalent (SE), axial length (AL) and RNFL thickness measurements were compared between the groups. To correct ocular magnification effect on RNFL, we used Littmann's formula. Results: All VKC patients had history of topical corticosteroid use and the mean duration of the topical corticosteroid use was 23.8 ± 9.09 months. There was no significant difference between the groups in terms of intraocular pressure (IOP). VKC group had significantly worse VA, greater SE and AL and thinner mean global, superior and inferior RNFL thickness. There were significant negative correlations between the duration of topical corticosteroid use and the mean global, superior and temporal RNFL thickness in VKC group. After correction of magnification effect, VKC group still had thinner mean global, superior and inferior RNFL thickness, and significant difference between the groups in inferior RNFL thickness did not disappear. Conclusion: Significant RNFL thickness difference between the groups suggests a possible effect of long-term corticosteroid use in VKC patients. Because visual field (VF) analysis in pediatric patients is difficult to perform and IOP may be illusive, RNFL thickness measurements in addition to routine examinations in VKC patients may help clinicians in their practice.
