Abstract
INTRODUCTION Tamoxifen citrate is an anti-estrogen agent used in the treatment of breast carcinoma. Crystalline maculopathy is a rare complication of tamoxifen therapy. The clinical picture resembles that of idiopathic macular telangiectasia (IMT) Type 2, which is a more common clinical entity. OBJECTIVE To report a case of crystalline maculopathy secondary to tamoxifen and highlight the importance of the medical history and investigations in differentiating it from IMT Type 2. CASE A diabetic female with a past history of breast carcinoma treated with tamoxifen came to the hospital for a routine eye check-up. Crystalline deposits were seen in the parafoveal region in both the eyes.The spectral domain optical coherence tomography (SD-OCT) showed foveal cysts in the inner retinal layer and fundus autofluorescence (FAF) and fundus fluorescein angiography (FFA) were within normal limits. CONCLUSION While tamoxifen maculopathy is reversible on stopping the therapy, IMT needs a long-term follow-up to monitor the potential risk of loss of vision due to choroidal neovascularization, hence necessitating the distinction between these two different clinical entities.
