Cone function in @entity1 with a history of XXXX .

@entity1 @entity3465 @entity989 @entity600
Color vision was examined by psychophysical tests and photopic color full-field electroretinography (ERG) in formerly preterm @entity1 , and compared with those of full-term @entity1 . In a prospective case-control study, 25 @entity1 with a history of @entity600 7-14 years of age were divided into three groups: group I, laser-treated @entity989 [ @entity989 ] (n = 7); group II, spontaneously regressed @entity989 (n = 8); group III, no @entity989 (n = 10). Age-matched full-term born @entity1 comprised the control group (n = 8). Color vision was assessed by Fansworth D15 and Lanthony desaturated D15 tests. The cone function was tested using photopic full-field ERG. Besides the ISCEV standard stimuli, blue light on amber background was also used (S-cone ERG). The correlation between ERG parameters and @entity3465 or @entity989 was determined. We found no significant differences between any @entity1 group and the control group in the results of the psychophysical tests, and implicit times of the ERG responses. The ERG b-wave amplitudes were significantly lower in group I (laser-treated @entity989 ) compared to controls, for 2 of 4 stimulus conditions i.e. the standard (P = 0.028) and S-cone (P = 0.017) single flash ERGs. The general estimating equation model statistics found a significant effect of @entity3465 on the b-wave amplitudes (P = 0.025, standard, P = 0.014, S-cone ERG). A slightly reduced photopic ERG b-wave amplitude may be associated with @entity3465 .
