The most up-to-date guidelines from the AAO for screening for chloroquine and hydroxychloroquine retinopathy have just come out. The recommended new objective tests are:
- Fundus autofluorescein (FAF)
- Spectral domain optical coherence tomography (SD-OCT)
- Multifocal electroretinogram (mfERG)
– An acceptable newer alternative is the MP-1
The goal of screening is to recognize toxicity at an earlier stage than the development of a visible bull’s eye maculopathy, which is a late change. Our Heidelberg Spectralis® HRA and OCT is one of the most sophisticated OCT instruments to do this.
We can provide these improved screening tools and newest knowledge about the prevalence of this toxicity question for your patients.
I would be happy to discuss this with you personally, if you have questions.
