Abstract

Purpose: To describe the clinical course and treatment outcomes of Vogt-Koyanagi-Harada (VKH) disease during pregnancy.

Methods: This retrospective study compares the clinical course and outcomes in pregnant and nonpregnant women with VKH. All VKH patients who were pregnant at presentation or on follow up and age-matched nonpregnant female controls during the study period (2013-2022) were included. Their best-corrected visual acuity (BCVA), clinical presentations, and treatment outcomes were analyzed.

Results: Among the 532 female VKH patients, nine (1.7%) were included. Thirty nonpregnant patients were included as control. At presentation, the mean age in the study group was 26 years ± 6.48 standard deviation (SD) compared to the control group (mean 25.1 years ± 3.04). The mean BCVA was comparable between the two groups at presentation (study group 1.35 logarithm of the minimum angle of resolution [logMAR] vs. control group 0.76 logMAR; P = 0.05) and the final follow-up (study group 0.65 logMAR vs. control group 0.35 logMAR; P = 0.15). Participants with anterior segment inflammation (study group 77.7% vs. control group 70%; P = 0.65), the disease stage (early-stage VKH: study group 88.8% vs. control group 73.3%; P = 0.33), and disease exacerbation (study group 33.3% vs. control group 26.6%; P = 0.69) were all comparable between the study and control groups. Following treatment, 66.6% and 46.6% of the study and control groups, respectively, had sunset glow fundus ( P = 0.29). At the last follow-up, 44.4% and 26.6% of the study and control groups, respectively, had subretinal fibrosis ( P = 0.31).

Conclusion: Though pregnancy is an immunomodulatory state, the clinical course of VKH in pregnant patients can be similar to that of nonpregnant women and needs close monitoring and follow-up.
