    Journal: Retina; 2008 Oct; 28(8):1111-6. PubMed ID: 18779718.
    Abstract:
    PURPOSE: To examine if vision in subjects with macular heterotopia (MH) secondary to retinopathy of prematurity (ROP) is related to anatomical macular structure. METHODS: Six subjects with MH who were between 18 years and 65 years of age and three age-matched subjects with normal vision were recruited for the study. Vision and macular structure of the better eye of the subjects with MH and the dominant eye of age-matched subjects with normal vision were assessed. High contrast visual acuity and contrast sensitivity were measured using Early Treatment of Diabetic Retinopathy Study and Pelli-Robson charts, respectively. The Micro Perimeter (Nidek Technologies MP-1) was used to assess macular sensitivity and fixation stability. Using optical coherence tomography, macular thickness and relative retinal thickness at fixation were measured. RESULTS: Subjects with MH had significantly reduced visual acuity and macular sensitivity compared with age-matched subjects with normal vision. In comparison with their age-matched counterparts, subjects with MH had significantly increased macular thickness and increased relative retinal thickness at fixation. A normal foveal architecture was absent in three subjects with MH (50%). CONCLUSION: Patients with MH secondary to ROP have increased macular thickness and reduced vision.
