Table 1 Choroidal vasculature changes and choroidal thickness and volume values in convalescent VKH patients compared to controls

From: Choroidal atrophy and loss of choriocapillaris in convalescent stage of Vogt-Koyanagi-Harada disease: in vivo documentation

  Patients Controls P value
No. 13 (22 eyes) No. 9 (17 eyes)
Choroidal thickness, mean ± SD (range), μm    
 Fovea 200 ± 60 (54 to 305) 288 ± 40 (229 to 350) <0.0001 (Student's t test)
 Parafovea 209 ± 61 (46 to 3.5) 278 ± 36 (209 to 333) <0.0001 (Student's t test)
 Entire macula 198 ± 58 (44 to 282) 268 ± 32 (202 to 318) <0.0001 (Student's t test)
Choroidal volume, mean ± SD (range), μm    
 Fovea 0.99 ± 0.31 (0.21 to 1.49) 1.49 ± 0.21 (1.17 to 1.82) <0.000 (Student's t test)
 Parafovea 1.28 ± 0.37 (0.29 to 1.9) 1.75 ± 0.23 (1.32 to 2.11) <0.0001 (Student's t test)
 Entire macula 5.33 ± 1.60 (1.01 to 7.33) 7.51 ± 0.93 (5.6 to 9.02) <0.0001 (Student's t test)
Preservation of choroidal vessel layers    
 Choriocapillaris-equivalent layer 11/22 (50%) 17/17 (100%) <0.000 (chi-square)
 Medium choroidal vessels 22/22 (100%) 17/17 (100%) 1
 Large choroidal vessels 17/22 (77%) 17/17 (100%) <0.000 (chi-square)
  1. Choroidal thickness and volume values in the eyes with convalescent Vogt-Koyanagi-Harada disease were significantly lower than those in controls. Also, the choriocapillaris and large choroidal vessels were significantly lost in convalescent Vogt-Koyanagi-Harada disease.
