[A new method to elicit pathological entoptic phenomenon from the retina--stenopeic flicker test].
Patients with central serous chorioretinopathy noticed that a part of the visual field became light for a few seconds when half of the visual field was covered in front of the eye. We devised a stenopeic flicker test (s-f test) to elicit this phenomenon continuously, and evaluated the clinical usefulness. We examined 17 eyes with central serous chorioretinopathy using the s-f test and Amsler grid test. Retinal abnormality was detected in 17 of 17 eyes with the s-f test and 14 of 17 eyes with the Amsler grid test. In detecting the extent of the retinal detachment on fluorescein angiograms, the s-f test (p < 0.0001, r = 0.842) was more precise than the Amsler grid test (p < 0.0003, r = 0.506). These results suggest that the s-f test is useful to detect retinal abnormality and to grasp the extest of the retinal detachment in central serous chorioretinopathy.
