ClinConnect Summary

Increased intraocular and systemic levels of the angiogenic factor vascular endothelial growth factor (VEGF) is associated with new vessel growth in the eye, such as diabetic retinopathy. Recent work using immunopathologic techniques have shown that VEGF is upregulated in both experimentally induced uveitis and in uveitic eyes as well, with no evidence of neovascularization. This pilot study will evaluate the level of VEGF in the blood of uveitic patients with and without macular edema. This level will be determined also in the ocular fluid of those patients that are undergoing ocular surge...

Eligibility criteria

  • For Uveitis Patients:
  • Evidence on ocular examination in the past or presently of intraocular inflammation, with cells and haze in the vitreous for the intermediate and posterior uveitis patients.
  • In order to demonstrate the presence or absence of macular edema, a fluorescein angiogram will be attempted on all patients. However, if the patient is unable or not willing to undergo the test, then if two observers from the LI can substantiate independently that there is or is not evidence of cystoid edema, the patient may be included.
