Summary of studies using SPARCS and Pelli Robson
| Study | ICC | COR | Remarks | ||
|---|---|---|---|---|---|
| Pelli Robson | SPARCS | Pelli Robson | SPARCS | ||
| Faria et al. [19] | 0.92 | 0.87 | NA | NA | 54 eyes ARMD, 66 eyes control, demonstrated lower scores in ARMD vs. controls (P < 0.001) |
| Richman et al. [6] | 0.98 | 0.97 | 6.43% | 6.66% | 118 glaucoma, 18 suspects and 125 controls, demonstrated the high test–retest reliability of SPARCS |
| Sun et al [18] | 0.620 | 0.635 | NA | NA | 182 eyes with varying amount of refractive errors, demonstrated that refractive error does not affect SPARCS scores if habitual correction is used |
| Gupta et al. [10] | |||||
| Cataract | 0.75 | 0.61 | 11.8% | 11.7% | 162 eyes (119 control and 43 cataract) demonstrated the effect of cataract on contrast sensitivity and ability of SPARCS and Pelli Robson to detect that effect |
| Control | 0.73 | 0.71 | 9.28% | 9.58% | |
| Present study | 0.952 | 0.988 | 12.44% | 5.65% | 135 eye with 45 each of controls, suspects and glaucoma patients |
