In molecular biology laboratories, many tasks require fine motor control and high acuity vision. For example, lab technicians with visual impairment experience difficulty loading samples into the small wells of a horizontal agarose gel. We have developed a 3D-printable gel loading system which allows technicians with low-contrast vision to load gels correctly. It includes a casting tray, a bridge, and a modified comb. The system provides a high-contrast visual field to improve visibility, and the bridge allows pipette tips to be inserted at the correct location and only to the correct depth. The necessary computer files for printing this device are freely available to increase the accessibility of molecular biology laboratories to people with visual impairment.

Early Patching Behaviors that Improve the Chances of Good Visual Acuity in Children Treated for Unilateral Congenital Cataract.
Ophthalmology
December 2024
Department of Ophthalmology, Stanford University, Palo Alto, CA.
Objective: Achieving near normal vision following unilateral congenital cataract surgery is possible but requires early surgery, optical correction and consistent patching. Patching is often challenging for children and their caregivers. The goal of these analyses is to examine the association between reported consistency in patching during the first year after surgery and visual acuity.

Global Health Institute, University of Antwerp, Antwerp, Belgium.
Introduction: Raga County is an onchocerciasis-endemic area in the Western Bahr El Ghazal state of South Sudan, known to have a high prevalence of blindness. The objective of this study was to determine the causes of eye disease and blindness in Raga County as well as to assess the relationship of eye diseases with other prevalent conditions like onchocerciasis and epilepsy.
Methods: We reviewed unpublished pre-community directed treatment with ivermectin (CDTI) data about eye disease and onchocerciasis in Western Bahr El Ghazal including Raga.
Duane Retraction Syndrome: A Report of Two Cases and Review of Literature.

Department of Ophthalmology, College of Medicine, University of Bisha, Bisha, SAU.
Stilling-Duane syndrome, a congenital condition characterized by aberrant innervation of the lateral rectus muscle and agenesis of the abducent nerve or its nucleus, results in limited horizontal eye movements. It is often misdiagnosed as acquired abducent nerve paralysis. This report highlights the importance of considering Stilling-Duane syndrome in differential diagnoses.

Purpose: To evaluate the anatomical and visual outcomes of patients with rhegmatogenous retinal detachment (RRD) who received primary repair by combined pars plana vitrectomy with scleral buckling (PPV/SB) or pars plana vitrectomy (PPV) alone by using a propensity analysis.
Patients And Methods: This study was a single center retrospective observational study. Medical records of patients who underwent surgical interventions between January 2013 and December 2019 were retrospectively reviewed.
