Objectives: To determine whether optic disc hemorrhages (ODH) and cotton wool spots (CWS) at presentation are associated with worse visual outcomes in pediatric patients with idiopathic intracranial hypertension (IIH).
Methods: Retrospective institutional review of 100 eyes of 50 consecutive pediatric IIH patients (aged 16 years or less) who had baseline optic disc photographs before or within 30 days of their diagnostic lumbar puncture and initiation of medical treatment. Optic disc photographs were independently graded by three ophthalmologists in a standardized manner.
Background/aims: It remains unclear whether the presence of optic disc haemorrhages (ODH) or cotton wool spots (CWS) at presentation in patients with papilloedema from idiopathic intracranial hypertension (IIH) has prognostic value. The aim of this study was to determine if optic disc appearance at presentation predicts visual outcome in patients with IIH.
Methods: Retrospective study of 708 eyes of 360 consecutive patients with IIH who had baseline optic disc photographs before or within 30 days of their diagnostic lumbar puncture and initiation of medical treatment.
Objective: To evaluate the relationship between CSF total protein concentration (CSF protein) and CSF opening pressure in idiopathic intracranial hypertension (IIH), and to explore the association of age, gender, race, BMI, and Humphrey visual field mean deviation (HVF MD) with CSF total protein.
Methods: The medical records of all IIH patients seen between 1989 and 2016 at one institution were systematically reviewed for demographics, CSF opening pressure, CSF contents, and HVF MD (at initial evaluation and most recent follow-up). Linear regression of CSF protein on CSF opening pressure was performed also considering BMI, age, gender, race, HVF MD, and year of lumbar puncture.
Purpose: This study seeks to determine the intraocular pharmacokinetics of molecules and particles injected into the suprachoroidal space of the rabbit eye in vivo using a hollow microneedle.
Methods: Suprachoroidal injections of fluorescein and fluorescently tagged dextrans (40 and 250 kDa), bevacizumab, and polymeric particles (20 nm to 10 μm in diameter) were performed using microneedles in New Zealand white rabbits. The fluorescence intensity within the eye was monitored in each animal using an ocular fluorophotometer to determine the distribution of the injected material in the eye over time as compared with intravitreal injection of fluorescein.
Purpose: To evaluate the transscleral delivery of fluoresceinated dextrans (FITC-D) with molecular mass up to 70 kDa to the rabbit posterior segment using sub-Tenon injections.
Methods: Eighteen NZW rabbits received a unilateral 200-μL injection of 2 mg/mL sodium fluorescein (NaF), 25 mg/mL 40-kDa FITC-D, or 25 mg/mL 70-kDa FITC-D, with (n = 9) or without (n = 9) immediate euthanatization. In live animals, fluorescence was measured in the retina/choroid and mid-vitreous by fluorophotometry, immediately after injection and after 4, 24, 48, and 72 hours.
