Distribution of Personality Type Based on Myers–Briggs Type Indicator in Central Serous Chorioretinopathy: A Pilot Cross-Sectional Study

Purpose: Central serous chorioretinopathy (CSC) has been associated with psychological stress and personality traits.This study investigated the distribution of Myers-Briggs Type Indicator (MBTI) personality types in CSC patients compared with the general population and explored their association with disease chronicity.Methods: Thirty patients diagnosed with CSC completed the MBTI questionnaire.Four MBTI dichotomies (Extraversion/Introversion [E/I], Sensing/Intuition [S/N], Thinking/Feeling [T/F], Judging/Perceiving [J/P]), attitude combinations (IJ, IP, EJ, EP), and function combinations (ST, SF, NT, NF) were analyzed.Overall distributions were compared with a Korean representative sample (n = 19,070) using chi-square tests with Monte Carlo simulation.Individual types and dimensions were assessed using exact binomial tests with Bonferroni correction, and acute-chronic subgroup comparisons were performed using Fisher's exact test.Results: Among CSC patients, 70% were classified as Introversion (vs.Extraversion) and 87% as Judging (vs.Perceiving) within their respective MBTI dichotomies.ISFJ was significantly more prevalent in the CSC group compared with the Korean general population (23.3% vs. 8.3%, p = 0.009), whereas INFJ showed a higher prevalence that did not remain significant after Bonferroni correction (13.3% vs. 3.0%, adjusted p = 0.058).The IJ attitude combination (53.3% vs. 27.4%,p = 0.005) and the SF function combination (50.0% vs. 30.3%,p = 0.027) were also more frequent in CSC patients, while the EP combination was not observed.No significant differences were observed between acute and chronic CSC subgroups.Conclusions: CSC patients demonstrated distinctive MBTI distribution patterns compared with the general population, including an overrepresentation of the ISFJ type and higher frequencies of the IJ attitude and SF function combinations.To our knowledge, this study represents the first application of an MBTI-based personality framework in patients with CSC.However, given the cross-sectional pilot design and limitations of MBTI-based assessment, these findings should be interpreted cautiously as exploratory rather than causal.
