Presumed ocular tuberculosis presenting as a branch retinal vein occlusion in the absence of retinal vasculitis or uveitis

eyes in this study may possibly be explained by the fact that these eyes had higher degrees of astigmatism than the control eyes (means = 4.38D vs 2.33D). CommentPrevious studies have assessed other tonometers (Tono-pen, Pro-Ton and ocular blood flow tonometer) in the measurement of IOP following keratoplasty, 8-10 but none have shown an advantage over GAT.This study suggests that DCT may be closer to providing the true IOP in these eyes, and may allow it to challenge GAT as the new gold standard in IOP measurement in this setting.
