Objective: To describe uveitis complications and visual acuity in a cohort of 500 patients in a multidisciplinary unit in northern Spain., Material and Methods: Retrospective-prospective study of complications and visual acuity of 500 adult patients evaluated in the Multidisciplinary Unit of the Navarra Hospital Complex from the period January 2010 until March 2015. An analysis was made of the complications, visual acuity and visual loss, with a follow-up of one-year. A comparative study was also made of the complications with 2 previous series published in Madrid and Holland., Results: Moderate-severe visual loss was 13.5% in the right eye, and 13% in the left eye. Visual loss was associated with an age of 65 years or above. Complications were observed in 35% of patients, and cataract was the most frequent complication (10%), followed by synechiae (8%), and macular oedema (5%). Compared with the 2 other series, the present cohort showed a higher proportion of cataracts., Conclusions: Visual loss was associated with older age and cataract was the most common complication in our study., (Copyright © 2019 Sociedad Española de Oftalmología.

Posterior reversible encephalopathy syndrome, previously known as Reversible posterior leukoencephalopathy syndrome, is a clinical-radiological condition characterized by headache, altered mental functioning, seizures and visual alterations, with the magnetic resonance imaging showing cerebral edema, predominantly in the white matter with posterior distribution. Multiple clinical conditions can act as triggers. We present five oncology patients, four of them with acute lymphoblastic leukemia, receiving chemotherapy when they presented with this pathology. A prompt diagnosis, an appropriate therapy for hypertension, and a rapid control of the seizures are the keys to avoiding sequelae., (Copyright © 2013 Asociación Española de Pediatría.
