Study information
Scientific title
Role of Atorvastatin for treatment of Central Retinal Vein Occlusion and long term prognosis
Acronym
ACRVOS (Atorvastatin for CRVO Study)
Study hypothesis
It has been suggested that in some instances an atherosclerotic central retinal artery impinges on the central vein, causing turbulence, endothelial damage and thrombus formation. Atorvastatin, with its lipid lowering action, may help in reducing the impingement on central retinal vein and therefore help in restoring the normal blood flow. Apart from the primary hypothesis, the protective role on endothelium may also be a determining factor for the final visual outcome.
Ethics approval
Ethics approval was not applied for since we don't have such a body here in India. Also, since the drug we plan to try is being prescribed for various other pathologies, this is just another indication which we might come up with.
This particular trial is the first one of the use of this drug for the given problem. There has not even been a case report of the drug use for CRVO. Since we have deeply studied the pathology of the disease and the action of the drug, we are expecting a positive response.
The patients will be fully informed of the nature of the treatment and only after consent will the drug be used.

Intervention
Intervention treatment:
Duration of atorvastatin planned to be given is for two months. Dosage is to be 10 mg per day, given once in a day, orally.
Control treatment:
Treatment as usual.
Both groups will be subject to Laser pan-retinal photocoagulation and regular protocol in case of any complications arising from CRVO.
Follow up will be for every third/fourth day upto a maximum of 15 days from the date of incident and then once every week for a period of month. A late follow up is planned at six months from the incident of CRVO and at one year.
Patients who report to us within 24 hours of CRVO will receive the regular care and treatment so as to release/dissolve the clot and restore normal flow and such cases will obviously be not included in any group. Since this treatment is usually not effective after a few hours, we have planned our study for cases presenting at a late stage and for long term prognosis.
