Pediatric Orbital High-Grade B-Cell Lymphoma: A Case Report and Review of the Literature.

Ocular involvement of lymphoma may present as a primary orbital or intraocular lymphoma or as a manifestation of metastatic disease. Involvement of various ocular structures may be difficult to diagnose due to its rarity and nonspecific clinical presentation. Primary high-grade B-cell lymphoma with MYC and BCL2 rearrangements of the orbit has rarely been reported in the adult population and has not previously been reported in the pediatric population.

Consensus Recommendations for Studies of Outflow Facility and Intraocular Pressure Regulation Using Ex Vivo Perfusion Approaches.

Intraocular pressure (IOP) elevation is the primary risk factor and currently the main treatable factor for progression of glaucomatous optic neuropathy. In addition to direct clinical and living animal in vivo studies, ex vivo perfusion of anterior segments and whole eyes is a key technique for studying conventional outflow function as it is responsible for IOP regulation. We present well-tested experimental details, protocols, considerations, advantages, and limitations of several ex vivo model systems for studying IOP regulation.

Patient-reported visual function outcomes agree with visual acuity and ophthalmologist-graded scoring of visual function among patients with long-chain 3-hydroxyacylcoA dehydrogenase deficiency (LCHADD).

Patients with LCHADD develop progressive chorioretinopathy with vision loss over time. To date, no data on the impact of vision loss on patient vision-specific activities of daily living or quality of life have been reported. We used validated ophthalmic patient-reported outcome measures (PROMs) to compare the impact of patient-perceived visual function to visual acuity and an ophthalmologist-graded stage of LCHADD chorioretinopathy.

High-resolution modeling of aqueous humor dynamics in the conventional outflow pathway of a normal human donor eye.

Background And Objective: The conventional aqueous outflow pathway, which includes the trabecular meshwork (TM), juxtacanalicular tissue (JCT), and inner wall endothelium of Schlemm's canal (SC) and its basement membrane, plays a significant role in regulating intraocular pressure (IOP) by controlling aqueous humor outflow resistance. Despite its significance, the biomechanical and hydrodynamic properties of this region remain inadequately understood. Fluid-structure interaction (FSI) and computational fluid dynamics (CFD) modeling using high-resolution microstructural images of the outflow pathway provides a comprehensive method to estimate these properties under varying conditions, offering valuable understandings beyond the capabilities of current imaging techniques.

Stereo slit-scanning tomography of the anterior segment of the human eye.

We demonstrate a new tomographic imaging device for 2D cross-sectional and 3D volumetric images of the anterior eye segment. The optical system combines optical sectioning with a stereoscopic camera setup to determine the true spatial location of the ocular structures. Moreover, we propose a calibration procedure to estimate the triangulation function that links the stereo camera pixel indices with the eye-referenced 3D spatial coordinates.

Anti-retinal Autoantibodies in Hydroxychloroquine Eye Toxicity.

Objective: Autoimmune retinopathy and hydroxychloroquine (HCQ)-related retinal toxicity share many similarities, raising the possibility autoimmunity plays a role in HCQ retinopathy. The objective of this study is to determine whether patients diagnosed with HCQ retinal toxicity are more likely to have circulating antiretinal autoantibodies (AAbs) compared to controls.

Methods: We tested plasma samples for the presence of anti-retinal AAbs by immunoblotting in 270 patients with systemic lupus erythematosus (SLE) receiving HCQ.

Variation between surgeons in reoperation rates following vertical strabismus surgery: Associations with patient and surgeon characteristics and adjustable sutures.

Purpose: To quantify inter-surgeon variation in vertical strabismus surgery reoperation rates, and to explore associations of reoperation rate with practice type and volume, surgical techniques, and patient characteristics.

Methods: Fee-for-service payments to providers in a national database for Medicare beneficiaries having vertical strabismus surgery between 2012 and 2020 were retrospectively analyzed to identify reoperations in the same calendar year. Predictors of the rate of reoperation for each surgeon were determined by multivariable linear regression.

Implementation of Artificial Intelligence in Retinopathy of Prematurity Care: Challenges and Opportunities.

The diagnosis of retinopathy of prematurity (ROP) is primarily image-based and suitable for implementation of artificial intelligence (AI) systems. Increasing incidence of ROP, especially in low and middle-income countries, has also put tremendous stress on health care systems. Barriers to the implementation of AI include infrastructure, regulatory, legal, cost, sustainability, and scalability.

Bilateral asynchronous acute idiopathic maculopathy with disease recurrence.

Purpose: Acute idiopathic maculopathy (AIM) is a posterior segment disorder that involves the neurosensory retina, retinal pigment epithelium, and choroidal circulation. When first described, the disease was classified as unilateral, but subsequent reports have found bilateral presentations. There is growing evidence to suggest the coxsackie virus as the etiology, however, other pro-inflammatory conditions have also been temporally linked to fundoscopic findings.

Differentiating MYCN-amplified RB1 wild-type retinoblastoma from biallelic RB1 mutant retinoblastoma using MR-based radiomics: a retrospective multicenter case-control study.

MYCN-amplified RB1 wild-type (MYCNRB1) retinoblastoma is a rare and aggressive subtype, often resistant to standard therapies. Identifying unique MRI features is crucial for diagnosing this subtype, as biopsy is not recommended. This study aimed to differentiate MYCNRB1 from the most prevalent RB1 retinoblastoma using pretreatment MRI and radiomics.
