Abstract:
Many classes of anticancer therapy, including chemotherapeutic agents, hormonal and molecular targeted treatments, can produce ocular toxicity. Novel agents that target different cellular pathways have been related to a wide spectrum of ophthalmologic toxicities that can range from mild to severe, and include conjunctivitis, blurred vision, keratitis and optic neuritis, among others. Special attention has been drawn to the inhibitors of the MEK signaling pathway, due to their sine qua non ocular toxicity, defined as MEK retinopathy and described as symmetrical bilateral disease that develops in a time-dependent and dose-dependent manner. In this review, we discuss ophthalmologic toxicities associated with molecular targeted therapies, with particular focus on MEK retinopathy, including its nomenclature, incidence, symptoms and management.
Insights
Molecular targeted therapies can cause ocular toxicity, including MEK retinopathy. This review details the incidence, symptoms, and management of these vision-related side effects.
Area of Science:
- Oncology
- Ophthalmology
Background:
- Anticancer therapies, including chemotherapy and targeted treatments, can cause ocular toxicity.
- Novel agents targeting cellular pathways are associated with various ophthalmologic toxicities, from mild to severe.
Purpose of the Study:
- To review ophthalmologic toxicities associated with molecular targeted therapies.
- To focus on MEK retinopathy, detailing its nomenclature, incidence, symptoms, and management.
Main Methods:
- Literature review of ocular toxicities from molecular targeted therapies.
- Specific focus on MEK inhibitors and their associated retinopathy.
Main Results:
- Molecular targeted therapies present a spectrum of ocular toxicities.
- MEK inhibitors are associated with a characteristic "MEK retinopathy".
Conclusions:
- Understanding and managing ocular toxicities from targeted therapies is crucial.
- MEK retinopathy requires specific attention due to its predictable occurrence with MEK inhibitors.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
