Rare presentation of choroidal neovascularisation in a case of congenital hypertrophy of retinal pigment epithelium.

A 22-year-old woman presented with a 2-week history of decreased vision, a central scotoma and metamorphopsia in her right eye. Her presenting visual acuity was 6/75 in the right eye and 6/6 in the left eye. Anterior segment examination was normal. Fundus examination of both eyes showed features of bilateral congenital hypertrophy of retinal pigment epithelium (CHRPE) lesions and choroidal neovascularisation (CNV) in the right eye. She was treated with intravitreal injection bevacizumab 1.25 mg/0.05 mL. One month later, there was regression of the CNV and subretinal fluid and her vision improved to 6/12. At the final follow-up visit, her vision was maintained at 6/9 with regression of CNV noted. To conclude, CNV is a rare association of CHRPE. It can lead to vision-threatening problem if it involves the macula and should be identified promptly and managed appropriately.
