Preferential-looking acuity and stereopsis in infantile esotropia

Journal of Pediatric Ophthalmology and Strabismus

Abstract

One hundred esotropic infants were assessed by preferential-looking (PL) for monocular acuity and stereopsis before the initiation of treatment. PL acuity of infantile esotropes who freely alternated fixation and of preferred eyes of unilateral esotropes was not significantly different from monocular acuity of age-matched normal infants. PL acuity of non-preferred eyes was normal during months three to five, but frequently below normal during months six to 14. Approximately the same percentage of normal and esotropic infants aged three to four months demonstrated stereopsis, but fewer esotropes than normals demonstrated stereopsis, during months five to 14. Ninety-five percent of infants judged non-amblyopic by the cover-uncover test also showed no evidence of amblyopia in the PL test. Overall, 42% of esotropic infants judged amblyopic by the cover-uncover test were found amblyopic by PL. Most discrepancies between PL and fixation preference (73%) occurred when clinically amblyopic infants under eight months of age were found non-amblyopic by PL. These findings suggest that fixation preference develops prior to the onset of amblyopia detectable by PL. The results of PL stereopsis testing suggest that stereoscopic pathways are p...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
