A case of uveoscleral mucosa-associated lymphoid tissue lymphoma with secondary angle-closure glaucoma.

Background/aim: Mucosa-associated lymphoid tissue (MALT) lymphomas occur in not only the ocular adnexa, but rarely in the sclera or uvea. Histopathological confirmation contributes to a better understanding of the pathogenesis and treatment. We report a case of uveoscleral MALT lymphoma with angle-closure glaucoma.

Intrascleral haptic fixation of intraocular lens (IOL) is an extremely useful technique to provide visual rehabilitation in eyes with inadequate capsular support. It requires exteriorization of haptics along with tucking of haptics in the scleral groove preferably and conventionally in the horizontal meridian. In eyes with large corneal diameter, there is difficulty in tucking enough length of the haptics into the intrascleral groove, carrying the risk of slippage of haptics and decentration of IOL.

Department of Ophthalmology, Yaan People's Hospital, Yaan City, Sichuan Province, China.
Objective: This study aimed to investigate the effect of axial elongation on anterior scleral thickness (AST) in myopia.
Methods: The convenience sampling method was used to select 122 patients without ocular or systemic diseases affecting ametropia in Ya'an People's Hospital between March 2020 and January 2022. According to the diopter and axial length (AL), the patients were divided into an emmetropia group (32 cases), a low-to-moderate myopia group (40 cases), and a high myopia group (40 cases).
Design and characterization of hollow microneedles for localized intrascleral drug delivery of ocular formulations.

Effective drug delivery to the posterior segment of the eye remains a challenge owing to the limitations of conventional methods such as intravitreal injections, which are associated with significant side effects. This study explored the use of hollow microneedles (HMNs) for localized intrascleral drug delivery as a minimally invasive alternative. Stainless steel HMNs with bevel angles of 30°, 45°, 60°, and 75° were fabricated using wire electron discharge machining.

Methods: Retrospective study of patients who underwent lasso in-the-bag scleral fixation of a subluxated PCIOL using the snare technique with Gore-Tex suture from 2019 to 2021 in a single tertiary medical center. Functional outcome was analyzed by clinical assessment, and anatomical outcome, by ultrasound biomicroscopy (UBM).
