Prior to beginning hydroxychloroquine:

* Blood samples to be taken.
* Baseline tests confirming diagnosis of CLL as defined above (if not already obtained in records)
* Physical exam performed
* Either six months prior or 4 weeks within starting HCQ ophthalmologic exam documented
* Days 1-365 subject takes hydroxychloroquine 400mg/day
* At 2 weeks: CBC and chemistry
* Every 4 weeks: CBC, chemistry, history (including the inquiry about the presence or absence of visual symptoms) and physical exam.
* Starting at 4 weeks: blood samples taken for laboratory companion studies taken at office visit every 8 weeks.
* At 6 months (+ or - 30 days): subject will have follow up ophthalmologic exam). This will also be done in the presence of any visual/ocular symptoms.

All subjects must meet the selection criteria for registration in this study. All subjects must have a peripheral blood sample submitted. It is estimated that approximately 70 subjects will be screened. The anticipated accrual period is 12 months.
