Inflammatory Cytokines in Congenital Cataract After Lensectomy and Anterior Vitrectomy

Overview

In this prospective study , a cohort of 58 eyes with congenital cataract from Wenzhou medical university was erolled.33 eyes with congenital cataract was after lensectomy and anterior vitrectomy as post-surger group, 26 eyes without cataract surgery as control group. The cytokines of MCP-1, VEGF, IL-1, IFN-γ, IL-1r,IL-4,IL-17, IL-2,IL-5,G-CSF,IL-12, IL-15 was evaluated

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: February 12, 2017

Detailed Description

Secondary IOL implantation in aphika children and lensectomy and anterior vitrectomy and primary IOL implantation in children with congenital cataract were both performed by the same surgeon(Z.Y.E) and videos were collected to review the capsular reconstruction condition and lens implantation position.

Aqueous humor (100-200 μl) was aspirated from each patient before the surgery. The research was to evaluate the relationship between the cytokine profile in aqueous humor and the state of capsule after Lensectomy and Anterior Vitrectomy.Aqueous humor was obtained , Human Magnetic Luminex Screening Assay was used to determine the aqueous humor levels of cytokines.

Interventions

  • Procedure: secondary IOL implantation
    • reopened the fibrotic, closed capsular bag and achieve IOL placement
  • Procedure: primary IOL implantation
    • lensectomy and anterior vitrectomy and primary IOL implantation

Arms, Groups and Cohorts

  • SIOL group
    • aphakic children diagnosed with congenital cataract who underwent secondary IOL implantation
  • PIOL group
    • children with congenital cataract who underwent lensectomy and anterior vitrectomy and primary IOL implantation

Clinical Trial Outcome Measures

Primary Measures

  • inflammatory cytokines
    • Time Frame: before the surgery of secondary IOL implantation
    • investigate inflammatory microenvironment changes in the aqueous of children after surgery.aqueous humor levels of cytokines, chemokines and growth factors including TGFβ2, TNF-α, IL-6, IP10, IL-10, MCP-1, VEGF, IL-1, IFN-γ, IL-1r,IL-4,IL-17, IL-2,IL-5,G-CSF,IL-12, IL-15.
