Outcome Measures

Primary Outcomes (2)

  • Incidence of glaucoma following congenital cataracts

    A Kaplan-Meier analysis was used.

    up to 10 years

  • Risk factors of glaucoma following cataract surgery

    To use Cox regression analysis to evaluate the potential risk factors in GFCS.

    up to 10 years

Study Population

Relying on the congenital cataract research platform established by our hospital, this prospective cohort clinical study will prospectively register children with congenital cataracts who underwent cataract extraction in our hospital from January 2010 to December 2016.

You may qualify if:

  • \) The guardian of the child voluntarily signed the informed consent;
  • \) The age is ≤18 years old, and the gender is not limited;
  • \) The diagnostic criteria for congenital cataract are met; the lens is opacified in one or both eyes;
  • \) The intraocular pressure before cataract extraction is normal ( less than 21 mmHg, considering the errors caused by different intraocular pressure measurement methods and different anesthesia methods);
  • \) The children have no glaucoma-related clinical manifestations and signs before cataract extraction, such as large corneal diameter, corneal edema or opacity, Increased cup-to-disk ratio, etc.;
  • \) The child has no family history of glaucoma;
  • \) Cataract extraction was performed in our hospital, and/or no intraocular lens was implanted;
  • \) Clinical diagnosis of glaucoma following cataract surgery
  • \) The postoperative follow-up time was not less than 60 months.

You may not qualify if:

  • \) Have received other eye surgery before enrollment, including cataract surgery, anti-glaucoma surgery, and corneal surgery, etc.;
  • \) Combined with congenital glaucoma, a clear history of eye trauma, and other complex eyes medical history (including persistent Persistent hyperplastic primary vitreous (PHPV), Peter's anomaly, congenital aniridia, Marfan syndrome, lens insufficiency, retinitis pigmentosa, high myopia, fundus lesions, congenital rubella syndrome, ocular brain-renal syndrome
  • \) Combined with other serious systemic diseases (cardiovascular, respiratory, digestive, urinary, nervous, and other system diseases)
  • Clinical diagnosis of glaucoma following cataract surgery:
  • after cataract removal, two or more of the following are required
  • Intraocular pressure: \>21 mmHg (investigator discretion on the method of measurement and if EUA (Examination Under Anesthesia) data alone is sufficient).
  • Visual fields: reproducible visual field defect that is consistent with glaucomatous optic neuropathy with no other observable reason for the visual field defect.
  • Axial length: progressive myopia or myopic shift with increased ocular dimensions that outpace normal growth.
  • Cornea: findings including Haab striae, corneal diameter \>11mm in newborns, \>12mm in children younger than 1 year old, and \>13mm in children older than 1 year old.
  • Optic nerve: progressive increase in the cup-disc ratio, cup-disc asymmetry of 0.2 when optic discs are of similar size, and focal rim thinning.
