Purpose : Torpedo maculopathy is a congenital ,benign , non – progressive , flat , pigmentary lesion seen temporal to the fovea with no gender predelection .We describe a series of cases with multimodality imaging along with OCT features in Torpedo maculopathy.
Methods : 3 cases are described, A 12 year old male, BCVA 20/20 . fundus examination of the LE showed an oval hyperpigmented lesion of 1.5 dd horizontal and 0.5 dd vertical which was temporal to the fovea .Case 2 was a 16 years old female patient with left eye Hypopigmented torpedo shaped lesion temporal to the fovea . case 3 - 33 year old male with right eye torpedo maculopathy lesion .
Results : Several theories have been proposed for the pathogenesis so far which include the developmental theory ,which suggested that the fetal RPE bulge corresponds to the site of torpedo maculopathy. vascular theory said that there is modification of the sclera to allow the long posterior ciliary nerves and artery to pass has aneffect on the developing of the choroid and RPE, accounting for this torpedo-shaped lesion. And the pigment theory suggested lack of melanin or production of an orange pigment that causes abnormal interaction between the RPE and the outer segments.
Conclusion : In our case series OCT demonstrated attenuation of the ellipsoid layer and RPE layer corresponding to the decrease in sensitivity on microperimetry in the area of the Torpedo lesion .
