Early diagnosis of pigmentary glaucoma with pseudo-normal pressure in a patient after radial keratotomy (case study)

Abstract

The article describes a clinical case of diagnostics and diagnosis of pigmentary glaucoma with pseudo-normal pressure in a patient who had previously underwent radial keratotomy (RKT).This case is interesting in that the detection of pigmentary glaucoma can be significantly complicated by a falsely low level of intraocular pressure (IOP) in the myopic eye after previous RKT and secondary hypermetropic shift, combined with the difficulty of an in-depth ophthalmoscopic assessment of the state of the optic nerve head in myopia, as well as perimetric study due to keratotomy scars. Tonometric IOP readings in such eyes should be considered carefully and supplemented with examination of other characteristic clinical signs of pigmentary glaucoma. This would help establish the diagnosis early and timely prescribe pathogenetic treatment.
