Eligibility Criteria:
Inclusion Criteria:~* Male and female subjects who are 18 years of age or older.~* Subjects in Treated Group:~* Subjects must have received linezolid 600 mg BID for six weeks or greater and be currently on drug (or have received linezolid within 7 days of baseline evaluation).~* Subjects who have current signs or symptoms compatible with linezolid toxicity (i.e. optic or peripheral neuropathy) may be enrolled in the study if they are on linezolid at time of baseline evaluation (or have received linezolid within 7 days of baseline evaluation).~* Linezolid may be discontinued at any time at the primary physician's discretion and remain on the study.~* Women of childbearing potential must use adequate contraception~* Subjects in Control Group:~* Subjects will have a diagnosis similar to patients in the treated group and similar important co-morbidities and epidemiologic factors if possible.~Exclusion Criteria:~* Subject in Treated Group:~* Subjects with a known presence of optic or peripheral nerve damage due to another illness, condition or medication.~* Subjects with a pre-existing or a diagnosis at time of screening visit of an ophthalmologic condition that would adversely affect the study testing protocol (e.g. dense cataracts, macular degeneration, retinitis pigmentosa).~* Subjects who are currently receiving or anticipated to receive another medication, antibiotic or other, that has known potential to produce ocular or neurologic toxicity indistinguishable from that caused by linezolid or lactic acidosis.~* Subjects with a history of significant exposure, in the opinion of the investigator and with prior discussion with the medical monitor, to medications known to produce optic or peripheral neuropathy.~* Subjects with an active communicable disease (i.e., tuberculosis assessed as currently communicable) and subjects on active treatment for tuberculosis or other mycobacterial disease that include drugs that have known potential to produce ocular or neurologic toxicity.~* Subjects with severe liver disease or abnormal liver function test.~* Subjects in Control Group:~* Subjects must not currently be taking linezolid or have received it for more than 7 days at any time.~* Subjects with a known presence of optic or peripheral nerve damage due to another illness, condition or medication.~* Subjects with a pre-existing or a diagnosis at the screening visit of an ophthalmologic condition that would adversely affect the study testing protocol (e.g. dense cataracts, macular degeneration, retinitis pigmentosa).~* Subjects who are currently receiving another medication, antibiotic or other, that has known potential to produce ocular or neurologic toxicity indistinguishable from that caused by linezolid or lactic acidosis.~* Subjects with a history of significant exposure, in the opinion of the investigator and with prior discussion with the medical monitor, to medications known to produce optic or peripheral neuropathy.~* Subjects with an active communicable disease (i.e., tuberculosis assessed as currently communicable) and subjects on active treatment for tuberculosis or other mycobacterial disease that include drugs that have known potential to produce ocular or neurologic toxicity.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Linezolid (Type: EXPERIMENTAL): Subjects have received at least 6 weeks of linezolid therapy (600 mg BID). Continued duration of linezolid treatment is based on treating physician's benefit/risk assessment. A matching control who did not receive linezolid will be selected for each linezolid treated subject.
- Matched control (Type: ACTIVE_COMPARATOR): Control subjects individually matched to linezolid subjects (on age, gender and type of infection) who received at least 6 weeks of antibiotics other than linezolid. Control group assessed only at baseline visit to assess presence of background abnormalities in the study test panel.

Based on this trial design, predict the completion outcome and termination type (if applicable).
