Hypothesis

Does intravitreal ranibizumab injection prevent clinically significant macular edema in patients with diabetic retinopathy after cataract surgery?

Conclusion

Intravitreal ranibizumab immediately after cataract surgery significantly reduces the incidence of clinically significant macular edema in patients with diabetic retinopathy.

Supporting Evidence

  • 25.92% of patients in the control group developed macular edema compared to only 3.70% in the ranibizumab group at one month post-surgery.
  • At three months, 22.22% of the control group had macular edema compared to 3.70% in the ranibizumab group.
  • The mean central macular thickness increased significantly in the control group but not in the ranibizumab group.

Takeaway

This study found that giving a special eye injection during cataract surgery helps stop swelling in the eye for people with diabetes.

Methodology

This was a prospective, randomized, controlled study with 54 patients assigned to receive either ranibizumab or no injection during cataract surgery.

Potential Biases

Potential selection bias due to the small number of participants.

Limitations

The study had a short follow-up duration and a small sample size.

Participant Demographics

54 patients, 35 women and 19 men, mean age 70.8 years.
