Lanthony desaturated panel D15 test in sickle cell patients
1National Eye Institute Clinical Branch, National Institutes of Health, Bethesda 20892.
Summary
Sickle cell retinopathy patients exhibit significant color vision defects, particularly blue-yellow impairments. The Lanthony D15 test effectively identifies these deficits in sickle cell disease (SCD) patients.
Area of Science:
- Ophthalmology
- Hematology
- Medical Diagnostics
Background:
- Sickle cell retinopathy is a complication of sickle cell disease (SCD).
- Color vision impairment can occur in individuals with SCD.
- Early detection of visual complications is crucial for managing SCD.
Purpose of the Study:
- To compare color vision between sickle cell retinopathy patients and healthy controls using the Lanthony D15 desaturated test.
- To evaluate the effectiveness of the Lanthony D15 test in identifying color vision defects in SCD.
- To assess the correlation between the Lanthony D15 and Farnsworth Munsell 100 Hue tests.
Main Methods:
- The Lanthony D15 desaturated test was administered to sickle cell patients with retinopathy and 20/20 visual acuity, alongside normal controls.
- Error scores and types of color vision defects were recorded.
- Correlation analysis was performed between Lanthony D15 and Farnsworth Munsell 100 Hue test scores for patients with sickle cell anemia (SS).
Main Results:
- Sickle cell patients demonstrated significantly higher Lanthony error scores compared to controls.
- Blue-yellow and mixed color vision defects were more prevalent in sickle cell patients.
- A significant correlation was found between Lanthony D15 and Farnsworth Munsell 100 Hue test scores in SS patients.
Conclusions:
- The Lanthony D15 desaturated test is a valuable tool for detecting blue-yellow color vision defects in sickle cell retinopathy.
- The test's simplicity and brevity make it suitable for clinical use in SCD management.
- Findings support the utility of the Lanthony D15 test in identifying color vision abnormalities associated with SCD.
