Hydroxychloroquine (Plaquenil) and chloroquine has been used for many illnesses such as lupus, rheumatoid arthritis and other inflammatory and dermatologic conditions. Plaquenil retinal toxicity can result permanent loss of vision. Early detection can make big differences on visual outcomes of retinal side effects. It is important to catch the side effect of drug early enough to reverse the changes otherwise irreversible drug effects.
According to revised Plaquenil screening protocol by American Academy of Ophthalmology, spectral domain OCT is the must have test to enable early detection. Spectral domain OCT scan is the only test that is sensitive enough to catch early changes much before other tests can detect. 
We offer Zeiss Cirrus Spectral HD OTC test. The test can be ordered by your doctor with / without our doctors interpretation and consultation. Please call us at 248-332-0200 to schedule your appointment today.
We made a high resolution retina scan down to cellular level available to Any Patients. Zeiss Cirrus HD-OCT (spectral domain retinal tomography) is the way to early-detect and monitor glaucoma, macular degenerations, diabetic eye diseases, medication induced retinal changes and subtle changes of vision. With this technology, we do not need to wait until diseases affect vision or eyes negatively to diagnose. Prominent studies suggest early changes of multiple sclerosis and even Alzheimer’s can be seen with retinal ganglion cell analysis with Zeiss Cirrus HD OCT Ganglion Cell Analysis.
