RESUMO

Objective:To observe the multimodal imaging characteristics of tamoxifen retinopathy.Methods:A retrospective case study. From January 2019 to December 2021, 4 patients (8 eyes) with tamoxifen retinopathy diagnosed in Tangshan Eye Hospital were included in the study. All patients were female, with sick binoculus. The age was 59.5±4.6 years. After breast cancer resection, tamoxifen 20 mg/d was taken orally consecutively, including 1, 1, and 2 cases who took tamoxifen orally for 5, 7, and ≥10 years. All eyes were examined by fundus color photography, optical coherence tomography (OCT), OCT angiography (OCTA), fundus fluorescein angiography (FFA), and fundus autofluorescence (AF). The multi-mode image features of the fundus of the affected eyes were observed.Results:The yellow white dot crystal like material deposition in the macular area was observed in all eyes. In fundus AF examination, macular area showed patchy strong AF. FFA examination showed telangiectasia and fluorescein leakage in macular area at late stage. OCT showed that punctate strong reflexes could be seen between the neuroepithelial layers in the macular region with the formation of a space between the neuroepithelial layers, the interruption of the elliptical zone (EZ), and the formation of a hole in the outer lamella including 4, 5 and 3 eyes; The thickness of ganglion cells in macular region decreased in 7 eyes. OCTA showed that the blood flow density of the superficial retinal capillary plexus around the arch ring was decreased, and the retinal venules were dilated in 2 eyes; Deep capillary plexus (DCP) showed telangiectasia.Conclusion:Deposition of yellowish white dot like crystals can be seen in the macular region of tamoxifen retinopathy; dotted strong reflex between neuroepithelial layers, cavity formation, thinning of ganglion cell layer, EZ middle fissure and outer lamellar fissure; DCP capillaries and venules around the arch were dilated; telangiectasia in macular region; flaky strong AF in macular region.

RESUMO

PURPOSE: Tamoxifen retinopathy is one of the uncommon side effects together with keratopathy, crystalline retinopathy and cystoid macula edema when tamoxifen is administered with high dose to breast cancer patients. We report here a case of retinopathy patient with five years of tamoxifen application. METHOD: A 46 year old female breast cancer patient complained about decreased visual acuity in both eyes after taking total amount of 37.28 g tamoxifen (20 mg/day) for 5 years. Whorl-like superficial corneal opacity was detected and yellowish white macular crystalline deposits were seen in both eyes. Moreover, decreased b wave amplitude of ERG was detected in electroretinography and RPE atrophy was found in FAG. RESULT: The patient stopped taking tamoxifen immediately after diagnosed with tamoxifen retinopathy. Two months later, it showed decreased corneal opacity and improved visual acuity in the left eye but also showed increased macular crystalline deposits in the left eye.
