Overview
Retinitis may be caused by multiple infectious agents including cytomegalovirus, toxoplasmosis, and candida. Retinitis Pigmentosa is classified as a genetic eye disease which occurs as a result of an inherited defect. [1]
Causes of Retinitis
Retinitis Pigmentosa
- Retinitis Pigmentosa is classified as a genetic eye disease, inherited from either one or both of a patient's parents. [2]
- The disease is a result of genetic defects in one of 50 genes required for the proper creation of photoreceptor proteins. [1]
- Generally the genetic disorder is linked to the inheritance of a recessive gene contributed by both parents. [2]
- Other cases have been linked to the inheritance of a dominant gene, defects of the X chromosome, and newly formed mutations caused by diseases.
- Progression of RP causes photoreceptor, cellular breakdown, both rods and cones.
- Ultimately, the progressive breakdown of photoreceptors leads to restricted vision or permanent loss of vision. [2]
Cytomegalovirus Retinitis
- Cytomegalovirus Retinitis is a result of viral, herpes infection of the retina.
- Highly prevalent as a cause of blindness within the AIDS infected population.
Other Causes
- Toxoplasmosis
- Candida
