Abstract:
Retinal diseases can be caused by genetic or non-genetic factors, and typically involve specific cell layers within the retina. A large number of simple Mendelian gene defects are known to affect the photoreceptor cell layer. As photoreceptor cells cannot be maintained in vitro, the study of animal models is instrumental in understanding the disease process and in testing therapeutic approaches. This review briefly summarizes those animal models of photoreceptor diseases with defined genotypes.
Insights
Animal models with defined genetic defects are crucial for studying retinal diseases affecting photoreceptor cells. These models aid in understanding disease mechanisms and evaluating potential therapies when photoreceptor cells cannot be cultured.
Area of Science:
- Ophthalmology
- Genetics
- Cell Biology
Background:
- Retinal diseases stem from genetic or non-genetic causes, impacting specific retinal layers.
- Photoreceptor cells are frequently affected by Mendelian gene defects.
- In vitro culture of photoreceptor cells is not feasible, necessitating alternative study methods.
Purpose of the Study:
- To review animal models of photoreceptor diseases with known genetic causes.
- To provide a resource for researchers studying inherited retinal conditions.
Main Methods:
- Literature review of studies on animal models of photoreceptor diseases.
- Focus on models with defined genotypes.
Main Results:
- Summary of various animal models exhibiting photoreceptor dysfunction due to specific genetic mutations.
- Highlighting the utility of these models in disease research.
Conclusions:
- Animal models with defined genotypes are essential tools for investigating photoreceptor diseases.
- These models facilitate the study of disease pathogenesis and the preclinical testing of therapeutic strategies for inherited retinal disorders.

Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...
