Tamoxifen is a selective estrogen receptor modulator commonly used in the treatment of breast cancer. It has been associated with specific ocular side effects, including whorl keratopathy and crystalline retinopathy. Whorl keratopathy is characterized by the deposition of lipid or drug in the corneal epithelium, resulting in a characteristic swirling pattern seen on examination. Crystalline retinopathy involves the presence of crystalline deposits in the retina, leading to visual disturbances.

The association of tamoxifen with these particular ocular manifestations stems from its interaction with cellular mechanisms that ultimately affect the corneal and retinal structures. Understanding this link is crucial for monitoring patients undergoing treatment with tamoxifen, as early recognition of these side effects can aid in managing and addressing potential visual complications.

In contrast, the other agents mentioned have different ocular side effects or are not primarily known for producing whorl keratopathy or crystalline retinopathy. This specificity towards tamoxifen for these particular ocular effects highlights its unique pharmacological properties and the importance of awareness among healthcare providers when managing patients on this medication.
