Purpose:
To report the response of cavernous haemangioma of the disc to PDT.
Methods And Patients:
A 32 years old lady presented to us with complaints of sudden onset of blurry vision in her right eye. What seemed initially as polypoidal choroidal vasculopathy turned out as cavernous haemangioma of the disc after pneumatic displacement of the sub-retinal haeme. She was treated with PDT as she was prone to recurrent haemorrhage from the lesion due to her low platelet count.
Results:
Complete regression of the cavernous haemangioma was noted as early as the second week itself and remained regressed for 4 months.
Conclusion:
PDT can be safe option for patients presenting with symptomatic cavernous haemangioma of the disc or retina.
