NCT ID: NCT04449900 Completed - Clinical trials for Optical Coherence Tomography Angiography

Quantitative Evaluation of Parafoveal Microvasculature Changes in Eyes With Exudative Circumscribed Choroidal Haemangioma: An Optical Coherence Tomography Angiography Study

Start date: March 1, 2017
Phase:
Study type: Observational

The study aims to quantitative evaluation of parafoveal microvasculature changes in eyes with exudative circumscribed choroidal haemangioma using optical coherence tomography angiography.

NCT ID: NCT04077489 Completed - Congenital Cataract Clinical Trials

Effects of 23-gauge Lensecotomy Combined With Anterior Vitrectomy on Macular in Children With Congenital Cataract

Start date: January 2016
Phase: N/A
Study type: Interventional

Congenital cataract is the main cause of form deprivation amblyopia in children. Current studies confirm that form deprivation amblyopia affects the macular development. However, there are different opinions about the effect of amblyopia on the macular thickness . Investigators have performed "cataract extraction with IOL implantation" on children with bilateral and unilateral congenital cataract. Investigators used OCT biometry to measure children's the macular thickness before and after surgery..Average sectional total thickness was automatically determined by the instrument's software using a modified Early Treatment Diabetic Retinopathy Study (ETDRS) circle grid (fovea, inner ring, and outer ring: 1 mm, 3 mm, and 6 mm. Investigators dynamically observed changes in macular to explore the retinal mechanism of form deprivation amblyopia and help guide the clinical correct understanding of postoperative follow-up time.
