Abstract
Background: Information on choroidal thickness may be helpful in a variety of clinical settings for diagnosis, treatment, and disease progression assessment. Aim: To assess the choroidal thickness in normal Pakistani eyes using swept source optical coherence tomography. Study design: Cross-sectional study Place and duration of study: Department of Ophthalmology, Shalimar Medical & Dental College from 1st March 2021 to 31st August 2021. Methodology: Three hundred eyes were included from 150 healthy individuals. A thorough eye examination was performed for all the included participants. Choroidal thickness was measured by using swept source optical coherence tomography. Results: The mean subfoveal choroidal thickness was 296.80±145.13 µ. The nasal outer macula was observed minimum mean choroidal thickness of 240.3±120.12 µ while in superior inner macula it was maximum mean choroidal thickness of 307.91±122.76µ. A non-significant (p=0.0731) and negative correlation (r = -0.0887) of age was observed with subfoveal choroidal thickness. The correlation of refractive error with subfoveal choroidal thickness was positive (r = 0.2271) and significant statistically (P = 0.001). Negative correlation (r = -0.3273) of the axial length was observed with subfoveal choroidal thickness (p=0.021). Conclusion: The increase of axial length and age, decreases in the choroidal thickness occur.
