For all cases of idiopathic congenital nystagmus visual acuity is reduced. This paper describes the analysis of such a system using some psychophysical methods of evaluation. Both the pattern and movement detecting responses are considered and discussed. Both of their sensitivities are found to be reduced by equivalent amounts. Future studies are outlined.

Optical resolution photoacoustic imaging of uneven samples without z-scanning is transformative for the fast analysis and diagnosis of diseases. However, current approaches to elongate the depth of field (DOF) typically imply cumbersome postprocessing procedures, bulky optical element ensembles, or substantial excitation beam side lobes. Metasurface technology allows for the phase modulation of light and the miniaturization of imaging systems to wavelength-size thickness.

Purpose: To study the role of intravitreal clindamycin with dexamethasone as an adjuvant to systemic co-trimoxazole and steroids in macular Toxoplasma retinochoroiditis.
Methods: Retrospective study of Toxoplasma retinochoroiditis cases from January 2014 to December 2021 treated with a combination of oral and intravitreal therapy in immunocompetent patients.
Results: 39 eyes of 39 patients were included in this study after meeting the inclusion criteria with the mean age of presentation being 25.

Heterogeneous catalysts have emerged as a potential key for closing the carbon cycle by converting carbon dioxide (CO) into value-added chemicals. In this work, we report a highly active and stable ceria (CeO)-based electronically tuned trimetallic catalyst for CO to CO conversion. A unique distribution of electron density between the defective ceria support and the trimetallic nanoparticles (of Ni, Cu, Zn) was established by creating the strong metal support interaction (SMSI) between them.

Purpose: To evaluate visibility of a sub-band posterior to the external limiting membrane (ELM) and assess its age-associated variation.
Methods: In a retrospective cross-sectional study, normal eyes were imaged using a high-resolution spectral-domain optical coherence tomography (SD-OCT) prototype (2.7-µm axial resolution).

Background: Pseudophakic cystoid macular edema (CME) following primary anterior-chamber intraocular lens (ACIOL) implantations is commonly seen. Intravitreal triamcinolone acetonide (IVTA) injections have shown significant improvement in visual acuity and retinal thickness in refractory pseudophakic CME. Pseudohypopyon following IVTA injection is a known entity.
