| EWooler - Question Would this be specifically - Capillary non-perfusion of retina? Similar to the newly added 1351545003 |Perifoveal capillary nonperfusion (finding)| - IR 16/10/24 - yes very similar to (1351545003) except higher level probably as not specifically referring to the perifoveal retinal location

|
|
21 | Diagnosis |
|
| some retinal thickening or hard exudates in the posterior pole, distant from the center of the macula | Mild diabetic macular edema | No |

|
|
22 | Diagnosis |
|
| retinal thickening or hard exudates near the center of the macula but not involving the center | Moderate diabetic macular edema | No |

|
|
23 | Finding |
|
| is the nonperfusion of the retina circumscribing the parafovea and fovea; perifovea is a belt that covers a 10 degree radius around the fovea and is 1.5 mm wide | Perifoveal capillary nonperfusion | No |

|
25 | Finding |

|
|
|
26 | Finding |
|
| is a common complication of diabetic retinopathy that is associated with damage in the vessels that supply blood to the retina and the enlargement of the foveal avascular zone | Macular ischemia | Yes | Retinal ischemia
