Visual field change in eyes with retinal pigment epithelial tear
Purpose:
To study the effects of retinal pigment epithelial (RPE) deprivation on retinal sensitivity with serial automated static perimetry in cases of RPE tear involving the foveal area.
Methods:
Two eyes with a tear of the RPE were diagnosed as such on biomicroscopic and fluorescein angiographic examination. Static perimetry was performed in the follow-up study with the Humphrey field analyzer central 10-2 program.
Results:
The first patient showed a dense scotoma corresponding to a defect in the RPE, which showed mild deterioration throughout the follow-up period from 2-11 weeks after the development of RPE tear. In contrast, the second patient showed preserved visual acuity and an absence of central visual field defects, despite an apparently denuded Bruch membrane involving the fovea during 8-month follow-up.
Conclusion:
Apparent RPE defect in eyes with RPE tears may or may not be associated with severe visual field defects. The pathophysiology of the disease should be studied, considering these perimetric findings.
