Effect of Intravitreal Bevacizumab on Focal Edema With Hard Exudates Secondary to Diabetic Retinopathy

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified September 2011 by Seoul St. Mary's Hospital.
Recruitment status was:  Recruiting

Purpose: To evaluate the efficacy of intravitreal bevacizumab (IVB) on focal edema with hard exudates secondary to diabetic retinopathy.

Design: Prospective interventional case series. Participants: Ten eyes of 10 consecutive patients showing focal edema with hard exudates secondary to diabetic retinopathy which are not eligible for focal laser photocoagulation due to central location (< 500 µm from fovea).

Condition Intervention

Further study details as provided by Seoul St. Mary's Hospital:

Primary Outcome Measures:
  • Changes in best-corrected visual acuity (BCVA) [ Time Frame: from month 0 to month 6 in monthly schedule (upto 6 months) ]
    ETDRS BCVA will be measured after 6 6 serial IVB.

Secondary Outcome Measures:
  • amount of hard exudates detected on fundus photography [ Time Frame: from month 0 to month 6 in bimonthly schedule (upto 6 months) ]
    on fundus photography

  • macular edema detected by optical coherent tomography [ Time Frame: from month 0 to month 6 in bimonthly schedule (upto 6 months) ]
    central subfield thickness will be measured.
