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.

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.
• The disease is a result of genetic defects in one of 50 genes required for the proper creation of photoreceptor proteins.
• Generally the genetic disorder is linked to the inheritance of a recessive gene contributed by both parents.
• 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.

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
