Long term result of intravitreal bevacizumab in a patient newly transformed to proliferative macular telangiectasia type 2

ABSTRACT

The clinical and imaging findings and therapeutic outcomes of intravitreal bevacizumab injection in a patient with macular telangiectasia type 2 are described. The patient first presented with the non-proliferative stage of the disease for 4 months, then the disease transformed to the proliferative stage. In the proliferative period, the patient was treated with intravitreal bevacizumab injections as-clinically warranted. Over a follow up period lasting 26 months, the patient received 6 intravitreal bevacizumab injections, the visual acuity improved from 20/100 to 20/40, the central retinal thickness decreased from 318 microns to 198 microns. This case implies that the patients with non-proliferative macular telangiectasia type 2 should be followed carefully for proliferative transformation, and intravitreal bevacizumab treatment seems to be effective for proliferative macular telangiectasia type 2
