Purpose: To evaluate whether providing clinicians with an artificial intelligence (AI)-based vascular severity score (VSS) improves consistency in the diagnosis of plus disease in retinopathy of prematurity (ROP).

Design: Multireader diagnostic accuracy imaging study.

Participants: Eleven ROP experts, 9 of whom had been in practice for 10 years or more.

Paediatric Cogan Syndrome is a rare and underrecognised autoimmune vasculitis characterised by ocular inflammation and sensorineural hearing loss. Its etiopathogenesis, diagnosis, and management are not well defined. We report a 12-year-old girl who initially presented with symptoms of IgA vasculitis formerly called Henoch Schoenlein Purpura (HSP) and eventually developed anterior uveitis and bilateral sensorineural hearing loss leading to the diagnosis of atypical Cogan Syndrome.

Purpose: To evaluate the accuracy and safety of oral fluorescein angiography (OFA) in differentiating papilledema from pseudopapilledema in pediatric patients.

Design: Retrospective evaluation of a diagnostic test.

Methods: We retrospectively reviewed medical records of all children ≤18 years of age who presented to the Arkansas Children's Hospital between May 2018 and August 2021 with suspected optic disc (OD) swelling that had OFA and images >30 minutes after oral ingestion.

Purpose: To report the case of a ten-year old girl with torpedo maculopathy with a complete vitelliform lesion and describe associated optical coherence tomography (OCT), OCT angiography (OCTA), multifocal electroretinogram (ERG) and adaptive optics ophthalmoscopy (AOO) imaging of the lesion.

Observations: An asymptomatic ten-year old girl with visual acuity of 20/15 OU was referred for evaluation of possible Best's disease of her left eye. The unilaterality, location, and shape of the lesion was consistent with torpedo maculopathy.

Purpose: The purpose of this study was to analyze the natural history and phenotypic overlap of patients with microcephaly and a chorioretinopathy or familial exudative vitreoretinopathy (FEVR) ocular phenotype caused by mutations in KIF11, TUBGCP4, or TUBGCP6.

Methods: Patients diagnosed with congenital microcephaly and chorioretinopathy or FEVR were included. Molecular investigations consisted of targeted genetic sequencing.

Purpose: To evaluate the phenotypic spectrum of autosomal recessive associated retinal dystrophies and assess genotypic associations.

Methods: A retrospective multicenter study was performed of patients with biallelic -associated retinal dystrophies. Data including presenting symptoms and age, visual acuity, kinetic perimetry, full field electroretinogram, fundus examination, multimodal retinal imaging, and genotype were evaluated.

The authors report a case of asymptomatic leukemic optic neuropathy as the first sign of acute lymphoblastic leukemia relapse in a 4-year-old boy. Routine ophthalmologic examination showed normal visual acuity and pupillary function in the presence of a tumoral mass covering the left optic disc. The mass resolved with preservation of vision after intrathecal chemotherapy.

We report the results of a comparative study at a single center on 214 eyes of 109 pediatric patients in whom IOP was measured using the Icare rebound tonometer and Goldmann applanation tonometry. Measurements from the two modalities demonstrated a correlation coefficient of 0.83 (P < 0.

Purpose: To determine whether the introduction of iCare rebound tonometry in a pediatric ophthalmology clinic resulted in fewer examinations under anesthesia to evaluate children with glaucoma.

Methods: The medical records of consecutive glaucoma patients were retrospectively reviewed. The numbers of examinations under anesthesia (EUAs) and office visits that included measurement of intraocular pressure (IOP) were compared for three periods relative to introduction of the Icare (Icare Finland Oy, Helsinki, Finland) rebound tonometer into our clinical practice: before device introduction, learning/transition period, and routine use.

Plesiomonas shigelloides rarely causes extraintestinal human disease, and infection of ocular tissues is even rarer, never having been reported as the sole pathogen of posttraumatic ocular infection. We report the first case of infectious keratitis due solely to P. shigelloides following traumatic corneal laceration and a literature review with regard to P.

Background: Benign external genital and perianal warts (condylomata acuminata) are disfiguring, displeasing skin tumours caused by human papillomavirus that may vitally burden affected patients and their partners. Current treatment options are still unsatisfactory due to low efficacy, high recurrence rates or an unfavourable side-effect profile. Although most recently prophylactic vaccines have been recommended for adolescent women, appropriate treatment modalities for anogenital warts are still needed.

Purpose: to report the difficulties in biometry in patients with cataract and synchysis scintillans and the way to avoid the biometrical errors in such patients.

Materials And Methods: Observational study on 4 patients (from 3 different surgeons) with cataract and synchysis scintillans.

Results: In two patients, the biometry obtained an increased IOL dioptrical value (+29D, and +28D, respectively) which proved to be wrong by not obtaining the planed emmetropia postoperatively.

A noninvasive method of quantitative assessment of cerebral blood flow based on heat clearance from brain tissues is described. The rate of heat clearance depends essentially on the blood flow. The employment of microwave techniques permits to warm the investigated brain zone and to record the temperature decrease extracranially.
