[Treatment of retinopathy of incontinentia pigmenti by anti-vascular endothelial growth factor].

Objective

To investigate the treatment of retinopathy of incontinentia pigmenti by anti-vascular endothelial growth factor.

Methods

Retrospective study of 5 patients(8 eyes) diagnosed retinopathy of incontinentia pigmenti from 2005 to 2017, including 0 males and 5 females (8 eyes involved) with an average age of 2.4 months(range, 1-5 months). Medical history and family history were recorded in detail for all children. We did the examination of anterior segment of the eyeball, vitreous body,fundus and intraocular pressure for the 5 patients(8eyes).What's more,wo also took pictures for fundus with the machine of Retcam. Fundus fluorescence angiography (FFA) was performed in 2 patients(4 eyes). Different surgical methods were selected according to the specific conditions of the eye and postoperative were observed.

Results

At the time of initial diagnosis, preretinal hemorrhage did not affect the macular region in 3 cases (5 eyes), pre retinal hemorrhage affected the macular region in 1 case(1 eye), the retinal neovascularization in 3 cases(5 eyes), the retinal detachment in 2 cases(2 eyes), and nonvascular zone of peripheral retinal in 5cases(8 eyes). Treatment and drug selection: 3 cases(5 eyes) were treated with injection anti-VEGF drug into vitreous body cavity, 1 case(1 eye) was treated with injection anti-VEGF drug into vitreous body cavity plus laser photocoagulation, 1 case(1 eye) was treated with anti-VEGF drugs plus vitrectomy. 1 case(1 eye) was treated with anti-VEGF drugs plus retinal cryotherapy and sclera bucking. In patients of injection anti-VEGF drug into vitreous body cavity, 2 cases(3 eyes) were given a single dose and 1 case (2 eyes) was given a repeated dose. Drug selection: 4 cases(6 eyes) ranibizumab injection (injection dose 0.025 ml), 1 case (2 eyes)conbercept injection (injection dose 0.025 ml). To follow-up date, etina was flat in 4 patients (7 eyes), epiretinal membrane in 2 patients(2 eyes), retinal detachment in 1 patient(1 eye).

Conclusions

The efficacy of anti-vascular endothelial growth factor in the treatment of retinopathy of incontinentia pigmenti was prelininarily confimed.However,the optimal use timing,dosage,local and systemic safety issues were needed to be further studied. (Chin J Ophthalmol, 2019, 55:294-301).
