More Than 10 Years Follow-up of Myopic Choroidal Neovascularization

Abstract

Abstract: : Purpose: To analyze long-term visual outcome in highly myopic patients with choroidal neovascularization (CNV). Methods: We reviewed the medical records of 25 consecutive patients (27 eyes) with myopic CNV who were followed for more than 10 years after the onset of CNV without therapy. Visual acuity (VA) was examined during 10 years after CNV onset. Results: At the onset of CNV, 70% of the eyes examined had better than 20/200 VA. Ten years after the onset of CNV, however, VA decreased to worse than 20/200 in 96% of the eyes. The change of the mean VA during follow-up, converted to logarithm of the minimum angle of resolution (logMAR), is shown in the Table. Although patients did not have any significant visual decrease until 3 years after the onset of CNV, there was significant worsening of VA at 5 and 10 years after the onset of CNV. Conclusions: This study indicates that over 5 to 10 years, natural course of visual outcome of myopic CNV is extremely poor . Based on this evidence, active treatments such as photodynamic therapy should be recommended for patients with myopic CNV. (Table)
