Background: Robot-assisted vitreoretinal surgery makes it easier for the surgeons to perform precise and dexterous manipulations required in vitreoretinal procedures.
Methods: We systematically evaluated manual surgery, conventional two-hand teleoperation, a novel one-hand teleoperation, and automation in a needle positioning task using a realistic surgical eye model, measuring the expert surgeon's performances and the novice's learning curves.
Results: The proposed one-hand teleoperation improved the positioning accuracy of expert surgeons , enabled novices to achieve a consistent accuracy more quickly , decreased the novice's workload more quickly , and made it easier for novices to learn to conduct the task quickly .
The synthesis of new agents for cancer treatment persists due to its global lethality. A series of thirteen derivatives, namely salicylic acid-5-sulfohydrazide (SA-SH) analogs, were designed and synthesized from 5-(chlorosulfonyl)-2-hydroxybenzoic acid via nucleophilic substitution reaction with different acid hydrazides, thiocarbohydrazide & thiosemicarbazide scaffolds. Confirmation of the designed derivative's structures employed various spectroscopic techniques (FT-IR and NMR) and elemental analysis.

Observations: At initial presentation, best-corrected visual acuity was hand motion at 20 cm in the right eye and 20/666 in the left eye. VH in both eyes and preretinal hemorrhage in the left eye was observed.
Purpose: To report a surgical technique of cyclopexy, wherein two laps of encircling continuous sutures are placed around the limbus to treat refractory extensive cyclodialysis.
Methods: Color fundus photography, swept-source optical coherence tomography (OCT) for the anterior segment, and spectral-domain OCT for the macula.
Results: Previous attempts, including indirect cyclopexy and direct external cyclopexy with gas injection, failed to successfully resolve the severe cyclodialysis and associated hypotonic maculopathy.
Purpose: To investigate recent trends in the cumulative incidence and treatment patterns of retinopathy of prematurity (ROP) in Japan.
Methods: A retrospective multicenter cohort was conducted from 2011 to 2020 using the Diagnosis Procedure Combination inpatient database. Preterm newborns with birth weight <2,500 g were categorized by birth weight.
