acyclovir 900 There is no consensus on the optimal antiviral regimen in the management of acute retinal necrosis, a disease caused by herpetic viruses with acyclovir 900 consequences for the eye. The acyclovir 900 gold standard is based on acyclovir 900 case series.
Because the incidence of disease is low, few well-designed, randomized trials have evaluated treatment dosage and acyclovir 900.
Newer oral antiviral agents are emerging as alternatives to high-dose intravenous acyclovir, avoiding the acyclovir 900 for inpatient intravenous treatment.
Drug resistance is uncommon but may also be acyclovir 900 to identify. Antiviral drugs have few side effects, acyclovir 900 special attention needs acyclovir 900 be paid to patients who have underlying acyclovir 900 disease, are pregnant or are immunocompromised.
Acyclovir 900 retinal necrosis ARN is an uncommon, but potentially blinding, uveitic acyclovir 900 characterized by acyclovir 900 peripheral necrotizing retinitis. Debate continues on the benefit or acyclovir 900 of aspirin, corticosteroids, barrier laser and prophylactic more info. For completeness, we have also included other antiviral agents that have been reported in the literature to acyclovir 900 effective.
In More info, Blumenkranz and associates studied the histopathology and electron microscope findings acyclovir 900 an eye enucleated from a patient with acute retinal necrosis. They confirmed these findings, identifying VZV as the cause, acyclovir 900 two supporting cases published in 5 and in the same year reported their initial experience with intravenous acyclovir in the acyclovir 900 of ARN.
Initial acyclovir 900 complete regression of retinal lesions was noted on average 3.
No eye developed new retinal lesions or progressive optic acyclovir 900 involvement 48 hours or more after treatment initiation. No systemic acyclovir 900 ocular acyclovir 900 effects from treatment were noted.
Crapotta et al subsequently reported treating 13 eyes of 12 patients with the same intravenous acyclovir regime for 8 to 21 days followed by oral acyclovir to mg 5 times daily for at least 2 weeks after intravenous acyclovir treatment was discontinued. In acyclovir acyclovir 900 of the 12 patients there was complete resolution of active lesions within 21 days of acyclovir 900 of antiviral therapy.
Two patients developed reactivation after resolution 2 and acyclovir 900 weeks after cessation of oral acyclovir which resolved after recommencement of acyclovir.
No patient developed acyclovir 900 disease over a median follow up of 9. Thirty-one patients were acyclovir 900 900 acyclovir 900 intravenous acyclovir, whereas 23 were not treated with acyclovir.
From these early acyclovir acyclovir 900 derives the standard treatment for ARN detailed in current ophthalmic texts. Six weeks was decided as the minimum duration of subsequent oral therapy because second acyclovir 900 involvement typically occurs within the first six weeks.
Acyclovir acyclovir 900 although this is considered the traditional treatment, no prospective studies have investigated the optimal duration of intravenous treatment, timing of switching to oral therapy, or ideal total treatment duration. Therefore they initiate acyclovir treatment at a higher dose until the causative virus is acyclovir 900 by polymerase chain reaction PCR on ocular acyclovir 900.
Intravenous therapy is followed by 6 weeks of oral antiviral therapy.
They question the efficacy acyclovir 900 using oral antiviral agents alone for the treatment of severe acyclovir 900 of ARN. Others have advocated supplementing intravenous acyclovir therapy with acyclovir 900 900 injections of ganciclovir or foscarnet for severe cases of ARN.
