Purpose:
To highlight the role of multicolor imaging to differentiate between the two cases presented, macular telangiectasia type 2 (MT 2) and tamoxifen retinopathy (TR) which have very similar phenotypical properties and can often present a diagnostic dilemma.
Methods:
Retrospective analysis of 2 cases, MT 2 and TR, presenting to a tertiary eye care center in Eastern India.
Results:
Both the cases show crystalline deposits and similar optical coherence tomography findings. However, MT 2 shows increased reflectance at the perifoveal region on multicolor imaging, while TR shows the same at the foveal region.
Conclusion:
Differentiating early TR and MT 2 can be challenging, and multicolor imaging, especially blue reflectance, can be very helpful in solving the dilemma and clinching the diagnosis.
