1/3. Asymmetric pigment dispersion in a patient with the unilateral Adie pupil.PURPOSE: Pigmentary glaucoma is a bilateral disorder. When it occurs asymmetrically or unilaterally, a cause should be sought because it may help us to understand the pathophysiology of this condition better. We describe a patient with unilateral pigmentary glaucoma and the Adie pupil in the same eye and discuss the possible role of the Adie pupil in the development of the pigmentary glaucoma. methods: A case report. A 37-year-old woman presented with asymmetric pigment dispersion resulting in pigmentary glaucoma in the right eye and an unilateral Adie pupil in the same eye. RESULTS: We believe that the dilated Adie pupil in the right eye might have resulted in a decreased amount of relative pupillary block. This, then, might have led to an increased contact between the posterior iris and the zonules, resulting in greater pigment dispersion and trabecular obstruction in the right eye. CONCLUSION: It has been proposed that the pigment is liberated from the iris pigment epithelium because of the mechanical rubbing of the posterior iris against the anterior zonular packets. Our case supports this proposed mechanism of pigment release.- - - - - - - - - - ranking = 1keywords = posterior (Clic here for more details about this article) |
2/3. Bilateral subacute angle-closure glaucoma in association with tonic pupils post-coronary artery bypass graft.Anterior and posterior visual pathway disturbances have been reported post-coronary artery bypass graft surgery. Acute angle-closure glaucoma after general anaesthesia has also been well described in the literature. To date, however, there are only two cases of angle closure caused by tonic pupils. The case is reported herein of bilateral subacute angle-closure glaucoma that occurred following coronary artery bypass graft surgery in association with tonic pupils.- - - - - - - - - - ranking = 0.5keywords = posterior (Clic here for more details about this article) |
3/3. Reversible posterior leukoencephalopathy and Adie's pupil after measles vaccination.Reversible posterior leukoencephalopathy syndrome is an increasingly recognized disorder with typical radiologic findings of bilateral gray- and white-matter abnormalities in the posterior regions of the cerebral hemispheres. The majority of patients with reversible posterior leukoencephalopathy syndrome are adults, and it is rare in children. Previously reported associations of reversible posterior leukoencephalopathy syndrome include hypertension, vasculitis, nephrotic syndrome, severe hypercalcemia, hemolytic uremic syndrome, eclampsia, renal failure, and use of immunosuppressive drugs. Adie's pupil is described as the presence of a large unilateral or bilateral tonic pupil related to virus infections or trauma. In this article, we describe a case of reversible posterior leukoencephalopathy and Adie's pupil association that occurred after measles vaccination. To our knowledge, this association has not been reported.- - - - - - - - - - ranking = 9574.9942282939keywords = posterior leukoencephalopathy, leukoencephalopathy, posterior (Clic here for more details about this article) |
