An Overview towards Zebrafish Larvae as a Model for Ocular Diseases

Area of Science:

• Ophthalmology
• Developmental Biology
• Genetics

Background:

• Zebrafish share conserved visual system architecture and cellular components with humans.
• The zebrafish retina is functional early in development, enabling visual function studies.
• Genomic resources facilitate genetic mapping and gene editing in zebrafish for ophthalmology.

Purpose of the Study:

• To highlight the utility of zebrafish as a model organism for studying human ocular disorders.
• To demonstrate the application of zebrafish in modeling various retinal diseases and pathologies.
• To emphasize the potential of zebrafish in regenerative medicine and drug discovery for visual system diseases.

Main Methods:

• Modeling inherited retinal diseases and congenital/acquired malformations.
• Inducing retinal pathologies like hypoxia and hyperglycemia to mimic human conditions (e.g., retinopathy of prematurity, diabetic retinopathy).
• Assessing ocular infections, autoimmune diseases, and aging processes in zebrafish larvae.

Main Results:

• Zebrafish successfully model a range of ocular pathologies, including retinopathy of prematurity and diabetic retinopathy.
• The model allows for the investigation of pathogenesis in ocular infections, autoimmune diseases, and aging.
• Retinal regeneration in zebrafish provides a unique advantage for studying degenerative processes.

Conclusions:

• Zebrafish serve as a powerful and versatile model for ophthalmological research, complementing mammalian models.
• The regenerative capacity of the zebrafish retina is crucial for developing novel therapies for degenerative eye conditions.
• Zebrafish research facilitates the discovery of new drugs and therapeutic strategies for visual system pathologies.
