    Author: Harju M, Saari J, Kurvinen L, Vesti E.
    Journal: Br J Ophthalmol; 2008 Jul; 92(7):901-5. PubMed ID: 18577639.
    Abstract:
    AIM: To study whether reversal of optic disc cupping after intraocular pressure (IOP) reduction is related to risk of glaucoma progression. METHODS: In this prospective follow-up study, where 51 patients with exfoliation glaucoma and five with ocular hypertension combined with exfoliation syndrome were followed for 6 years after IOP reduction, 24 showed progression of glaucoma in visual fields or optic nerve head (ONH) stereophotographs. ONH topography was measured with the Heidelberg Retina Tomograph (HRT). A decrease in HRT parameter cup volume of more than 5% was considered cup reversal. Multiple logistic regression was used to model progression of glaucoma. RESULTS: Cup reversal (OR 0.226; 95% CI 0.055 to 0.918, p = 0.037), final IOP (OR 1.216; 95% CI 1.000 to 1.479, p = 0.050) and visual field mean defect at entry (OR 1.158; 95% CI 1.034 to 1.296, p = 0.011) were associated with progression. IOP change from study entry to 6-year control visit was not associated with progression (OR 0.964, 95% CI 0.850 to 1.092, p = 0.56). CONCLUSION: Cup reversal seemed to be an independent protective factor for progression of glaucoma.
