Sar of chloroquine slideshare Chloroquin for aquarium How to take plaquenil for lupus In the present day, the less toxic HCQ is used instead of chloroquine. The American Academy of Ophthalmology revised the screening guidelines in 2011 to include spectral domain-optical coherence tomography SD-OCT, fundus autofluorescence FAF, and multifocal ERG mfERG when available to assess the macula in patients taking HCQ. The new. Multifocal ERGs better quantify retinal toxicity than full-field ERGs. Below are mfERGs of several patients with Plaquenil toxicity. Plaquenil first affects small areas between 5-15 degrees from fovea eventually progressing to produce a ring scotoma. Figs. 47 and 48. Fig. 47. The multifocal ERG mfERG simultaneously measures local retinal responses from up to 250 retinal locations within the central 30 degrees mapped topographically. This new technology was developed by Erich Sutter in the early 1990s and involves powerful computers and high –intensity display monitors. She was previously treated with hydroxychloroquine (Plaquenil) 200mg bid (6.5mg/kg) for 10 years, which was stopped one year prior to presentation. She suffered from Sjogren syndrome and inflammatory arthritis and was currently treated with prednisone and methotrexate.

I keep on complaining that the vision in my left is deteriorating and I am not seeing properly but my testing is coming out normal. My docotor is now ordering this test as a baseline and to prove to me that my. MultiFocal ERG DailyStrength. Electroretinogram - EyeWiki. Multifocal ERG in Practice -. Dr. Marmor said, “We also recommend use of objective tests such as spectral domain OCT, multifocal ERG and fundus autofluorescence.” He added that older time domain OCT units lack enough sensitivity for Plaquenil toxicity. Go by ideal, not real, weight. Dr. Because early toxicity changes can be revealed on SD-OCT, it is prudent to perform a baseline screening of patients taking Plaquenil. Multifocal ERG has the ability to detect early macular dysfunction, so it should be included as part of baseline screening. A maximum daily dose of Plaquenil of 5.0mg/kg real weight is recommended. Twenty patients on Plaquenil treatment were evaluated for retinal toxicity using the EOG and the mfERG. Group 1 comprises 15 patients 30 eyes with normal EOG. From these patients 11 22 eyes showed normal RRD of mfERG in area 1 and area 2. The rest four patients 8 eyes the RRD were reduced. Six months after interruption of HC, the mfERG improved in three cases. Group 2 comprises 5.
