Insights

Ocular auto-stimulation (OAS) and related eye problems are common in advanced Retinopathy of Prematurity (ROP). Higher post-conceptional age is linked to OAS in these patients.

Area of Science:

  • Ophthalmology
  • Neonatal care
  • Pediatric eye diseases

Background:

  • Retinopathy of Prematurity (ROP) is a leading cause of childhood blindness.
  • Stage 5 ROP represents the most severe form, characterized by total retinal detachment.
  • Ocular auto-stimulation (OAS), or eye-pressing behavior, is frequently observed in infants with severe ROP.

Purpose of the Study:

  • To investigate the prevalence, characteristics, and associated morbidities of ocular auto-stimulation (OAS) in stage 5 Retinopathy of Prematurity (ROP).
  • To identify factors influencing the occurrence and severity of OAS in this vulnerable population.

Main Methods:

  • Retrospective analysis of stage 5 ROP cases from a tertiary care center (January 2017 - December 2017).
  • OAS categorized as infrequent or frequent based on parental history.
  • B-scan ultrasonography for retinal detachment configuration and automated keratometry in eyes undergoing vitrectomy.

Main Results:

  • OAS was present in 78.5% of eyes (73/93).
  • Higher post-conceptional age was significantly associated with OAS (P=0.018).
  • Enophthalmos was significantly more common in eyes with OAS (P=0.001), while corneal opacity and posterior synechiae showed no significant association.

Conclusions:

  • Ocular auto-stimulation and its associated morbidities are prevalent in stage 5 ROP.
  • Post-conceptional age and residual visual function appear to influence OAS characteristics.

5-Number Summary

In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Stages of General Anesthesia01:22

Stages of General Anesthesia

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Stages of Sleep01:22

Stages of Sleep

Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Stages of Infection01:26

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Stimulants01:29

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Psychosexual Stages of Personality: Latency01:16

Psychosexual Stages of Personality: Latency

Following the phallic stage in Freud's theory of psychosexual development, children enter a phase called the latency period, which lasts from approximately six to twelve years of age. Unlike earlier stages, where sexual impulses played a central role, Freud believed these impulses are repressed during the latency period, becoming part of the unconscious. This stage is often described as a time of psychological calm after the turbulence of the phallic stage.
The latency period is not...
