Insights

Premature infants with cicatricial retinopathy of prematurity, refractive error, family history, or poor neurodevelopment are at higher risk for strabismus. These findings aid in managing premature children and future strabismus etiology research.

Area of Science:

  • Ophthalmology
  • Pediatrics
  • Neonatology

Background:

  • Strabismus is a common ocular misalignment.
  • Premature birth is a known risk factor for various developmental issues, including visual impairments.

Purpose of the Study:

  • To identify independent risk factors for strabismus in children born prematurely.
  • To inform management strategies and future research on strabismus etiology.

Main Methods:

  • Prospective study of children born before 32 weeks' gestation.
  • Standardized ophthalmological and pediatric examinations at 2 years of age.
  • Logistic regression analysis to determine risk factors.

Main Results:

  • Strabismus risk increased with cicatricial retinopathy of prematurity, refractive error, family history of strabismus, and poor neurodevelopmental outcome (impaired locomotor skills, hand-eye coordination).
  • Gestational age and regressed acute retinopathy of prematurity were not independent risk factors.
  • 558 premature children were evaluated, representing 98.6% of the study cohort.

Conclusions:

  • Identified independent risk factors for strabismus in premature infants.
  • Distinguished between direct and indirect contributing factors to strabismus.
  • Findings support improved clinical management and targeted research into strabismus causes.

Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
Varicose Veins I: Introduction01:26

Varicose Veins I: Introduction

Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
