  Purpose

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
Diabetes Complications Drug: Avastin (bevacizumab)

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

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.
