Assessment of intraocular measurements in neonatal foals and association with gender, laterality, and body weight: a clinical study.

The research focuses on taking measurements within the eyeballs of newborn horses, also known as foals, and looking at whether any associations exist between these measurements and the foals’ gender, which eye is being looked at (right or left), and the foal’s weight. However, no significant relationship was found between these factors and the intraocular measurements. The study provides initial reference values for intraocular measurements in newborn foals, which could contribute to diagnosing and treating both inborn and later developed diseases affecting the eye.

Objective of the study

• The main aim of this research was to describe the intraocular, or inside the eye, measurements in newly born foals within their first week of life. These measurements are unique to individual animals and could be influenced by factors such as gender, the right or left eye, and the body weight of the foal.
• Assessing the potential relationship between these factors and the intraocular measurements could provide valuable insights into understanding the development of the eye in newborn foals.
• This knowledge can then be used to help diagnose and treat both congenital (present from birth) and acquired (developing later in life) diseases that affect the eyeball.

Methodology

• The researchers performed biometric scans, which are precise measurements related to living organisms, using B-scan ultrasonography on the eyes of 22 healthy foals in their first week of life.
• Various measurements were taken within the eye, including the depth of the anterior chamber (the space in the eye in front of the iris), the thickness of the central lens, the depth of the vitreous chamber (the clear gel that fills the space between the lens and the retina), among others.
• The research also compared these measurements with aspects such as the foal’s gender, which eye was scanned, and their body weight.

Results and conclusions

• The study found that none of the factors assessed — gender, right or left eye, and body weight — had a significant influence on the measurements taken within the foal’s eyeball.
• The results of this study provide baseline reference values for intraocular measurements of foals within their first week of birth. These could further aid in the diagnosis and treatment of eye related diseases in foals.
