Purpose: To investigate changes to the vitreoretinal interface in uveitis with multimodal imaging including adaptive optics.
Methods: Four eyes (four patients) affected by fovea-attached (subtype 1A) or fovea-sparing epiretinal membranes (ERMs) on spectral-domain optical coherence tomography or visible internal limiting membrane (ILM) on infrared scanning laser ophthalmoscope (SLO) fundus imaging were recruited in this pilot study. The microstructure of the vitreoretinal interface was imaged using flood-illumination adaptive optics (FIAO), and the images were compared with the cross-sectional spectral-domain optical coherence tomography data.
Purpose: To describe our experience with locally developed evidence-based guidelines for oral fluorescein angiography (FA) for retinal imaging in children.
Methods: The medical records of consecutive pediatric patients (≤18 years of age) at University of Pittsburgh Medical Center Children's Hospital Eye Center who underwent oral FA between November 1, 2018, and April 1, 2022, were reviewed retrospectively. Adherence to or deviation from the guidelines was noted at the time of testing.
Background: Visual electrophysiology may be used to assess visual potential in infants with congenital corneal opacities (CCO). It is essential to recognize confounding effects from these opacities on the flash electroretinogram (ERG).
Methods: ERGs were recorded in awake children employing skin electrodes placed at the lower eyelid crease, both referred to a midfrontal electrode (Fz).
Purpose: To describe a patient with retinoblastoma and subsequent maculopathy unrelated to the tumor but related to intra-arterial melphalan documented by pattern electroretinography.
Methods: Comprehensive ophthalmic evaluation, treatment with intra-arterial chemotherapy and subsequent follow-up including electroretinography to assess for macular dysfunction.
Results: A 3-year-old child was evaluated with electrophysiological investigations following treatment of unilateral Group D retinoblastoma with intra-arterial and intravitreal chemotherapy with melphalan.
Background: : Alagille syndrome (AS) is a multisystem disorder associated with a range of ocular anomalies affecting the anterior and posterior segments. While chorioretinal abnormalities have been reported in Alagille Syndrome, identification of macular dystrophy and detailed clinical and electrophysiologic descriptions are scarce.
Materials And Methods: : A retrospective review was conducted to identify patients with a diagnosis of AS and retinal disease who were evaluated in the Division of Pediatric Ophthalmology, Strabismus, and Adult Motility at UPMC Children's Hospital of Pittsburgh.
