ABSTRACT
PURPOSE: To report a case of typical delayed-onset hypoxic cortical blindness that occurred few days after resuscitation from drowning in a young male. METHODS: Neurological and ophthalmological examination were performed including optical coherence tomography (OCT), Goldmann perimetry, pattern electroretinogram (pERG), pattern and flash visual evoked potentials (pVEP and fVEP) and brain magnetic resonance imaging (MRI). RESULTS: At presentation, at day 12 post-hypoxic incident, best corrected visual acuity (BCVA) was reduced to hand motion OU with an abolished optokinetic nystagmus, a normal fundus and no relative afferent pupillary defect. Macular and peripapillary OCT were normal. Goldmann perimetry revealed bilateral centrocecal scotoma. pERG was normal while pVEPs were undetectable and fVEPs were abnormal with delayed, decreased and disorganized responses, without interhemispheric asymmetry. Brain MRI disclosed a bilateral cortical-subcortical occipital hypersignal with laminar necrosis and thus confirmed the diagnosis of delayed-onset hypoxic cortical blindness. Visual rehabilitation, including visual stimulation in the scotomatous areas, was associated with a dramatic and rapid visual improvement with a BCVA of 20/32 OU, an ability to read after 2 weeks (day 30 post-hypoxic incident), and a reduction in the size of the scotoma. CONCLUSION: Delayed-onset hypoxic cortical blindness is a rare presentation of cortical blindness that develops few days after a cerebral hypoxic stress. While initial presentation can be catastrophic, visual improvement may be spectacular and enhanced with visual rehabilitation.

PURPOSE: To examine the relation between uveitis and common variable immunodeficiency (CVID). METHODS: Retrospective analysis of patients included in the French DEFI cohort of adults with CVID and of patients identified by reviewing the literature. RESULTS: Four patients were identified in the DEFI study (frequency of uveitis: 1.6%). The course of uveitis was not changed in the patients who started intravenous immunoglobulins replacement therapy after CVID diagnosis. Ten cases of CVID-associated uveitis were listed in the literature. Overall, among the 14 patients, uveitis was always chronic, usually bilateral (n = 11) and granulomatous (n = 9). Seven patients presented with a "sarcoid-likeâ syndrome. Nine patients had granulomatous uveitis suggestive of ocular sarcoidosis. Five patients were treated with local corticosteroids, and 9 required systemic treatment (corticosteroids alone n = 5 and/or immunosuppressive agents n = 4). CONCLUSIONS: CVID can be associated with uveitis. Since uveitis can reveal the immunodeficiency, CVID diagnosis should be considered at the time of uveitis diagnosis.
