Title

TORPEDO MACULOPATHY: A CASE REPORT

Introduction

Torpedo Maculopathy is a congenital and rare asymptomatic change of the retinal pigment epithelium (RPE), temporal to the macula. This lesion is usually unilatera. Visual Acuity is not affected, but it may be associated with other complications such as Central Serous choroidopathy and choroidal neovascularization.

Methods

Case report and review of literature.

Results

Female , 70 years old, complaining of low visual acuity in the left eye. Visual acuity of 20/30 in the right eye and counting fingers in the left eye. On this occasion, Polypoidal Vasculopathy was diagnosed in OS through the Optical Coherence Tomography (OCT). Four Intravitreal Injections of Ranibizumab were performed in the OS which currently has visual acuity: 20/80. In a routine examination in 2013, for evaluation of dermatochalasis, Binocular indirect ophthalmoscopy revealed a temporal scar alteration to right macula. The visual acuity in both eyes was 20/25.

Discussion

The nevus Solitary Pigmented Retinal Epithelium (torpedo maculopathy), first described by Roseman, Gass in 1992, is a rare congenital anomaly, with no known etiology, which produces a rupture of the layers of the outer retina. It is suspected of being qualified with changes in the development of choroidal or ciliary vascularization. Several theories have been proposed to explain the pathogenesis of the lesion. Differential diagnosis are: Chorioretinal scar, retinal trauma, congenital RPE hypertrophy, RPE hamartoma and retinal dystrophies. Although benign it must be monitored periodically due to the possibility of progress or progression to choroidal neovascularization.
