Background: Concussions are mild traumatic brain injuries that often cause vision problems. They have significant impacts on everyday life, cognitive capacity, and sports performance, and may affect injury prevalence in fast contact sports such as ice hockey. A functional vision questionnaire specifically designed for sports was used here to study the correlation between vision problems and concussion history.

Methods: In this national cross-sectional concussion study, 860 Finnish elite-level male adolescent ice hockey players (aged 13-21 years) answered a functional vision questionnaire and performed a computerized neurocognitive test, ImPACT. Totally 265 athletes reported a history of at least 1 concussion. All data were statistically compared with age-matched athletes with no concussion history (n = 595). For further analysis, athletes were divided into subgroups by age and number of previous concussions.

Results: Previously concussed athletes reported more general and eye-specific symptoms than their healthy controls. Increases in eye fatigue, frontal headaches, and blinking were statistically significant. Also statistically more problems with depth perception and evaluating distances, concentration problems, blurred vision, and losing the object in sight were observed among athletes with concussion history.

Conclusions: Concussion history reflects an increase in the prevalence of vision deficits, as determined by multiple disturbances in the near triad. The significant number of vision problems in the concussion history groups strongly suggests that functional vision should routinely be evaluated in athletes. The vision problems observed in the athletes with concussion history may indicate an increased injury risk that should be addressed.

Background: Idiopathic intracranial hypertension (IIH) mainly occurs in women of a reproductive age who are overweight or obese. As pregnancy occurs in this age group, it is important to understand whether there are associations between IIH and pregnancy. The purpose of this study was to determine the incidence of IIH development during a pregnancy and whether IIH is associated with hypertensive disorders of pregnancy (HDP).

Methods: In this retrospective cohort analysis, electronic health records from a tertiary care center were used to identify patients with IIH. Patients who had a diagnostic code for IIH or papilledema and were seen between June 1, 2012, and September 1, 2023, were included. After meeting the revised Dandy diagnostic criteria, patients were evaluated for a history of pregnancy before, during, or after their IIH diagnosis and hypertensive disorders including preeclampsia/eclampsia, HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome, and hypertension. Incidence and risk ratios (RR) were calculated comparing patients with IIH with controls without IIH. To corroborate these results while controlling for obesity and migraine, the TriNetX platform housing more than 100 million patients was used to design a case-control analysis evaluating the odds of an IIH patient having an HDP.

Results: Two hundred ninety-two IIH patients with a prior pregnancy were identified of which 7% developed new onset IIH during pregnancy. Patients had increased risks of all HDP including eclampsia (RR: 12.92, 95% CI: 5.35, 31.22), preeclampsia (2.39, CI 1.84, 3.10), and HELLP syndrome (6.72, CI 2.16, 20.90) compared with controls. Patients with IIH also had higher risks of ectopic pregnancies and miscarriages (P < 0.05). When controlling for obesity and migraine, patients continued to have increased odds of all HDP and eclampsia (P < 0.05).

Conclusions: Patients with IIH had an increased risk of having an HDP, especially eclampsia and HELLP syndrome highlighting a need for increased clinical monitoring of these patients during pregnancy.
