Summary
Chloroquine therapy can cause rare but serious bilateral ocular toxicity, particularly in patients with systemic lupus erythematosus. This dose-dependent retinal damage highlights the need for ongoing vigilance despite screening methods.
Area of Science:
- Ophthalmology
- Rheumatology
- Pharmacology
Background:
- Chloroquine is a medication used to treat autoimmune conditions like systemic lupus erythematosus.
- Ocular toxicity is a known, albeit uncommon, side effect of chloroquine treatment.
Observation:
- Two cases of bilateral ocular toxicity were observed in women undergoing chloroquine therapy for systemic lupus erythematosus.
- The presented cases underscore the potential for severe visual impairment associated with this treatment.
Findings:
- Retinal toxicity from chloroquine is an iatrogenic condition that is dependent on the dosage.
- Despite current ophthalmic screening techniques, new instances of chloroquine-induced retinopathy continue to be reported.
Implications:
- Clinicians should be aware of the risk of chloroquine retinopathy, even with regular eye screenings.
- Careful dose management and patient monitoring are crucial for preventing irreversible ocular damage in patients on long-term chloroquine therapy.
- Further research may be needed to refine screening protocols for early detection of chloroquine ocular toxicity.

01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
01:24Drug Toxicity: Risk factors
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
