ABSTRACT

The purpose of this study is to evaluate the vision and posterior segment of eyes in children and young adults less than 22 years of age with risk, suspicion, or past medical history significant for elevated intracranial pressure (ICP). Patients will have visual acuity and color vision tested. Assessment of the posterior segment will involve using a non-invasive (non-contact) imaging technique (i.e. a portable fundus camera in clinic and hospital settings). Detailed Description The need for non-invasive evaluation of ICP is an active area of study. The current gold standard is intraventricular or intraparenchymal catheters but these are invasive, expensive, and require sedation; and thus the need for an effective non-invasive screening tool. The utility of funduscopy in identifying processes affecting ICP has long been recognized, i.e. papilledema, ocular venous engorgement, blurring of the optic disk. Studies have demonstrated that funduscopy may have a role in the qualitative assessment of increased ICP as a highly sensitive test. However, conventional bedside funduscopy does not allow for image capture and may necessitate pupillary dilation. Portable fundus cameras address these issues, allowing image capture and storage and the potential for non-mydriatic imaging, i.e. imaging without dilation of eyes. And as demonstrated in a recent study, portable fundus cameras are efficient (median exam time was 3 minutes and 24 seconds in a pediatric Emergency Department). Additionally, ICP screening in asymptomatic patients remains limited. Patients being treated with medications for acne, specifically tetracyclines (e.g. minocycline and doxycycline), retinol, and isotretinol, are at particular risk for increased ICP but often are not identified until they are symptomatic (i.e. headaches, visual loss, papilledema). Symptom onset has been documented from 2 weeks up to 1 year from drug initiation. The percentage of patients with subclinical asymptomatic disease is unclear. This study would allow us to describe the presence of subclinical disease in our population and the role/utility of routine non-invasive screening methods. More... »
