Table [1]: A total of 36 SLE patients were divided into two groups: Group (1) included 18 patients with lupus nephritis, and Group (2) included 18 patients without nephritis. Group (3) consisted of 15 age- and sex-matched healthy individuals as controls. The sample included 11 males (21.6%) and 40 females (78.4%) across all groups. The mean ages were 33.94 ± 9.95, 34.39 ± 9.36, and 32.93 ± 6.75 years for Groups 1, 2, and 3, respectively, with no statistically significant difference between them (p = 0.892)
The mean disease duration was longer in Group (1) than in Group (2). Regarding BCVA, although visual acuity appeared lower in Group (1) compared to Groups (2) and (3), and Group (2) lower than Group (3), the differences did not reach statistical significance (p > 0.05)
