Assessment of Color Vision in Blood Cancer Patients

Abstract

Color vision is the eyes capacity to distinguish between distinct light wavelengths, which allows
for the experience of color. The retinas cone cells, which react too various light wavelengths to
create a variety of colour experiences, help with this function. The objective of this study is to
“Assessment of color vision in blood cancer patients”. This descriptive cross-sectional study
includes 100 clinically diagnosed blood cancer patients between the age range of 20-40. Color
vision was assessed by Ishihara plates. The study included 100 participants, with a higher
proportion of males(62%) compared to females (38%). The majority of participants had leukemia
for 1-12 months (79%), while 21% had leukemia for 13-24 months. Regarding right eye diagnosis,
80 participants(80%) had normal vision, 11 (11%) had protanopia, and 9 (9%) had deuteranopia.
For the left eye, 72 participants (72%) had normal vision, 19 (19%) had protanopia, and 9 (9%)
had deuteranopia. When analysing vision diagnosis by gender, among males, 46 had normal
vision in the right eye, 9 had protanopia, and 7 had deuteranopia, while among females, 34 had
normal vision, 2 had protanopia, and 2 had deuteranopia. In the left eye, 41 males had normal
vision, 14 had protanopia, and 7 had deuteranopia, whereas among females, 31 had normal vision,
5 had protanopia, and 2 had deuteranopia. To investigate the relationship between leukemia
duration and vision diagnosis, a chi-square test was conducted. For the right eye, the test result (χ²
= 1.330, p = 0.514) showed no significant association between leukemia duration and vision
impairment. Similarly, for the left eye, the chi-square test (χ² = 1.525, p = 0.466) also indicated no
significant relationship. These findings suggest that the duration of leukemia does not have a
statistically significant impact on vision diagnosis in either eye. No significant association was
found between gender, leukemia duration, and the diagnosis categories for both the right and left
eyes.
