Ocular biometry of the cynomolgus monkey

Area of Science:

• Comparative Ophthalmology
• Primate Ocular Anatomy
• Biometry

Background:

• Establishing normative ocular biometric data is crucial for preclinical research.
• Cynomolgus monkeys are a common model in ophthalmology studies.
• Understanding ocular parameter variability in this species is essential.

Purpose of the Study:

• To perform ocular biometry on cynomolgus monkeys.
• To establish baseline measurements for key ocular parameters.
• To investigate correlations between ocular parameters and body weight.

Main Methods:

• Ocular biometry was conducted on eight cynomolgus monkeys.
• Measurements included horizontal corneal diameter, anterior corneal curvature, anterior chamber depth, lens thickness, vitreous cavity length, and total internal axial length.
• Statistical analysis was performed to assess correlations with body weight.

Main Results:

• Mean body weight was 3.04 +/- 0.59 kg.
• Key ocular parameters such as corneal diameter (9.79 +/- 0.47 mm) and axial length (17.16 +/- 0.69 mm) were recorded.
• A significant correlation was observed between body weight and most measured ocular parameters.

Conclusions:

• This study provides normative ocular biometric data for cynomolgus monkeys.
• Body weight is a significant factor influencing ocular dimensions in this species.
• These data are valuable for the design and interpretation of ophthalmic research using cynomolgus monkeys.
