All of the patients underwent congenital cataract extraction and intraocular lens (IOL) implantation successfully. Optical coherence tomography angiography (OCTA) was performed to image the retinal vasculature in the macular and optic disc areas before and after surgery. The differences in vessel density and retinal thickness between groups were compared.Results: We found that the best corrected visual acuity (BCVA) was significantly improved one month after surgery compared with that before surgery (t=5.179, p< 0.001). The axial length was also changed one month after surgery (t=5.350, p< 0.001). The vessel density in the macular and optic disc areas of the affected eyes was significantly lower than that in the normal eyes, while the vessel density at the posterior pole was significantly improved one month after cataract extraction.Conclusion: The decrease in vessel density in the macular and optic disc areas might be a consequence of the congenital cataract. Cataract extraction can relieve the form deprivation of the affected eye and increase the vessel density at the posterior pole of the affected eye significantly.Keywords: unilateral congenital cataract, OCTA, cataract extraction, vessel density, form deprivationZhang WHu HCheng HLiu QYuan DDove Medical Pressarticleunilateral congenital cataractoctacataract extractionvessel densityform deprivationOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 4221-4228 (2020)
