Changes in choroidal thickness of FD and fellow control eyes in animals raised under FL-4000 (n = 18) (A), SL-4000 (n = 12) (B), SL-6500 (n = 9) (C), and interocular differences (IOD: form-deprived eye – control eye) in choroidal thickness of eyes in chicks exposed to FL-4000, SL-4000, and SL-6500 (D). Statistical significance *** (P < 0.001); #: The IOD in choroidal thickness in FD eyes exposed to SL-6500 was significantly higher than in those exposed to FL-4000 (P = 0.02). CTR, control eyes; FD, form-deprived eyes. Shaded area between D1 and D14 indicates the period of form-deprivation. Data are represented as average ± SD.
