Intensive Glycemic Control Did Not Affect Diabetic Eye Changes in 1 Year, reveals research

The research involved 254 adult patients with T2DM, all of whom were more than 7% at baseline HbA1c. Participants were followed by researchers for 12 months, and HbA1c values at baseline and follow-up were obtained. Participants were grouped based on the 12-month HbA1c levels:

• Intensive glycemic control group: 129 patients attained HbA1c < 7%

• Less intensive control group: 125 patients had HbA1c ≥ 7%

The severity of diabetic retinopathy was graded with seven-field 45° conventional fundus photographs, and DR status changes—incidence, progression, and regression—were graded by UK National Diabetic Eye Screening Program guidelines. Data were also adjusted for age, gender, and other confounding factors such as BMI, blood pressure (systolic and diastolic), diabetes duration, insulin use, and baseline HbA1c.

Key Findings

• Total participants: 254 T2DM patients with baseline HbA1c > 7%

• The follow-up duration was: 12 monthsThe intensive glycemic control was attained by: 129 patients (HbA1c < 7%)

• The less intensive group consisted of: 125 patients (HbA1c ≥ 7%)

• Outcome: No substantial difference in DR incidence, progression, or regression between the two groups

• Adjustments: Incorporated age, gender, BMI, SBP, DBP, duration of diabetes, insulin therapy, and initial HbA1c

The study reaches the conclusion that intensive glycemic control within 12 months has no significant effect on short-term changes in diabetic retinopathy in patients with T2DM. These results reinforce the necessity for ongoing long-term observation and overall management plans for diabetic eye disease.
