  • Clinical features and treatment of 12 cases with incontinentia pigmenti-associated retinopathy

    ObjectiveTo observe and analyze the clinical features, treatment methods and efficacy of patients with retinopathy associated with incontinentia pigmenti (IP).MethodsA retrospective case study. Twelve clinical confirmed IP patients (24 eyes) in Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2015 to December 2018 were included in this study. The best corrected visual acuity and intraocular pressure examination were performed in patients (>4 years old). All patients were examined on the anterior segment, vitreous body, and fundus under topical anesthesia or general anesthesia. Eight cases underwent genetic testing. Patients with active disease should be given anti-vascular endothelial growth factor (VEGF) drug treatment, retinal laser photocoagulation or vitrectomy, those without active disease should be observed. All patients were followed up for 1 to 3 months, with an average follow-up time of 18.7 months.ResultsAll patients were all female, with an average age of 6.3±9.8 years old at the first ophthalmology visit. According to the recommendations of the pediatrician, 3 cases were actively screened for ophthalmology (referrals), with an average age of 0.4±0.5 years (median age: 2 months). A total of 9 cases were not recommended for referrals (non-referrals), including 3 cases of ophthalmology who were diagnosed for the first time due to visual impairment, and 6 cases of undiagnosed IP before the ophthalmology visit, the average age of their first visit was 8.2±10.8 years (medium age: 3 years old). The age of the first visit for non-referred patients was larger than that of referrals, and the difference was statistically significant (Z=−2.141, P=0.036). Among the 24 eyes of 12 cases, there were no obvious fundus abnormalities in 1 case or 2 eyes, 11 cases of IP-related retinopathy in 22 eyes (91.7%, 22/24), 8 cases of binocular asymmetry (66.7%, 8/12). There were active lesions on the fundus in 7 eyes (29.2%, 7/24). Patients underwent simple retinal laser photocoagulation and/or anti-VEGF drug therapy. During the follow-up, retinal neovascularization recurred in 1 eye. Among the 8 cases that underwent genetic testing, 3 cases (37.5%, 3/8) were deleted in exons 4-10 of the IKBKG gene.ConclusionsIP is more common in women. IP-associated retinopathy is noted with early-onset, asymmetrical retinopathy, which is identified with retinal neovascularization and vitreous proliferation. Early detection and timely treatment are essential.
