Cytomegalovirus (CMV) retinitis is a viral inflammation of the retina of the eye.
Alternative NamesCMV retinitis
Causes, incidence, and risk factorsCMV retinitis is caused by a member of a group of herpes-type viruses. CMV is very common. Most people are exposed to CMV in their lifetime, but typically only those with weakened immune systems become ill from CMV infection. Serious CMV infections can occur in people who have weakened immune systems due to:
- AIDS
- Bone marrow transplant
- Chemotherapy
- Drugs that suppress the immune system
- Organ transplant
Note: Many patients with CMV retinitis have no symptoms.
Symptoms include:
- Blind spots
- Blurred visionand other vision problems
- Floaters
Retinitis usually begins in one eye, but often progresses to the other eye. Without treatment, progressive damage to the retina can lead to blindness in 4-6 months or less.
Even with regular treatment, the disease can worsen to blindness. This may be because the virus becomes resistant to the drugs so that the drugs are no longer effective, or because the patient's immune system has deteriorated further.
Patients with CMV retinitis also have a chance of developing retinal detachment, in which the retina detaches from the nerves of the eye, causing blindness. Systemic CMV infection also can occur.
Signs and testsCMV retinitis is diagnosed through a standard ophthalmologic exam. Dilation of the pupils and ophthalmoscopy will show signs of CMV retinitis.
CMV infection can be diagnosed with blood or urine tests that look for substances specific to the infection. A tissue biopsy can detect the viral infection and presence of CMV virus particles, but this is rarely done.
TreatmentThe goal of treatment is to stabilize or restore vision and prevent blindness. Long-term treatment is often needed. Medications may be given by mouth (orally), through a vein (intravenously), or injected directly into the eye (intraviteously).
Expectations (prognosis)The disease will sometimes get worse, even with treatment, because antiviral medications stop the spread of the virus but do not destroy it.
Complications- Blindness
- Kidney impairment (from drugs used to treat the condition)
- Low white blood cell count (from drugs used to treat the condition)
- Retinal detachment
If symptoms worsen or do not improve with treatment, or if new symptoms develop, call your health care provider.
People with AIDS (especially those with a very low CD4 count) who have vision problems should make an appointment for an immediate eye exam and should consider taking preventive treatment for CMV retinitis.
PreventionCMV infection that causes symptoms normally occurs only in those with weakened immune systems. People with AIDS who have a CD4 count of less than 100 should be examined regularly for retinitis even if they don't have symptoms.

Ocular manifestation of cytomegaloviruscmv?
Cytomegalovirus (CMV) can cause various ocular manifestations, such as retinitis, optic neuritis, and uveitis. CMV retinitis is the most common and can lead to vision loss if not treated promptly. Patients with weakened immune systems, like those with HIV/AIDS, are more prone to developing ocular manifestations of CMV.

What gene is mutated in retinitis pigmentosa?
Mutations in the RP1 gene have been associated with retinitis pigmentosa. RP1 is involved in the function and structure of the retina, and mutations in this gene can lead to progressive vision loss characteristic of retinitis pigmentosa.

What Is the Treatment for Retinitis Pigmentosa?
Retinitis pigmentosa is a rare eye disease that affects the retina by creating the light-sensitivity). It basically targets light-sensitive layers of tissue in the back of the eyes. Retinitis pigmentosa breaks down cells connected in the retina gradually over time and causes slow vision loss.
What are the causes symptoms of Retinitis Pigmentosa?
Retinitis Pigmentosa, also know as RP is a rare eye condition that affects the layer of the eye that is sensitive to light - the Retina. Retinitis Pigmentosa is a genetic disease that is passed on through generations and the type of vision loss varies. Patients suffering from Retinitis Pigmentosa lose eyesight over time but do not become completely blind. What are the causes of Retinitis Pigmentosa? Patients suffering from Retinitis Pigmentosa lose eyesight over time but do not become completely blind. Being a genetic issue, the main cause of RP is generational that happens because of changes in our genetics that end up leading to damage in the control cells in the Retina. What are the symptoms of Retinitis Pigmentosa? The main symptoms of Retinitis Pigmentosa are: - Loss in side vision or peripheral vision - Loss if vision in the night or in the dark - Problems distinguishing colours - Loss of central vision If you are facing any of the above symptoms, it is impetrative to meet your doctor at the earliest. Doctors at Sanjeevan Netralaya understand that every patient is different with different genes and understand the patient history before prescribing effective Ayurvedic Medication that is not only effective but also causes absolutely no side effects.
