Background: Posterior scleritis (PS) is a rare phenotype of scleritis. Comprehensive epidemiological studies on PS in children are limited. We aimed to report on its clinical and imaging features in one of the largest pediatric series to date.

Effect of Hydration on Viscoelastic Tensile Properties of Sclera.

Vision (Basel)

January 2025

Mechanical and Industrial Engineering Department, University of Illinois Chicago, Chicago, IL 60607, USA.

The present work characterized the effects of hydration on the viscoelastic tensile properties of the sclera. Scleral strips were dissected from the posterior region near the optic nerve head of porcine eyes in the superior-inferior direction. The samples were divided into four hydration groups and their mechanical response was characterized by conducting uniaxial tensile stress-relaxation experiments.

Background: Lens implantation becomes a major concern in patients lacking posterior capsular support, but various methods are available for rehabilitation. In such patients, scleral-fixated intraocular lens (SFIOL) implantation is preferred due to its fewer complications and better simulation of the natural lens position. In this non-randomized retrospective clinical study, we aimed to assess visual outcomes after sutureless SFIOL implantation in aphakic patients and factors affecting visual outcomes.

Objectives: To evaluate scleral thickness of patients with keratoconus by anterior segment optical coherence tomography (AS-OCT).

Materials And Methods: Fifty-two eyes of 42 patients with keratoconus (group 1) and 42 right eyes of 42 healthy individuals (group 2) were included. Scleral thickness measurements were taken with AS-OCT 6, 4, and 2 mm behind the scleral spur in four gaze positions: superior, inferior, temporal, and nasal.

Purpose: To describe a custom bent 27-gauge needle-guided suture snare technique for scleral fixation of posterior chamber intraocular lenses (PCIOL).

Methods: An 8-0 polypropylene suture was threaded into the lumen of a custom bent 27-gauge needle, and the needle tip was advanced into the eye from the intraocular lens (IOL) fixation point. The suture was threaded through the posterior limbal incision inside the IOL haptic loop and pulled out.
