NCT00970723

Brief Summary

Macular edema remains a major cause of vision impairment in diabetic patients. Its pathogenesis is multifactorial and incompletely understood. Systemic factors seam to play a role in this pathogenesis, including high blood pressure. The objective of the study is to evaluate the effect of an intensified intervention on blood pressure and sleep apnea with that of conventional treatment in patients with type 2 diabetes and diabetic macular edema.

Outcome Measures

Primary Outcomes (1)

  • The primary outcome will be the percentage of patients having a sustained 50% or more-decrease in retinal thickening at 1 year, assessed with OCT in the study eye.

    M13

Secondary Outcomes (4)

  • Percentage of patients having a 2 ETDRS lines or more-increase in visual acuity at one year in the study eye

    M13

  • Number of ocular interventions (laser photocoagulation, intra ocular injections) in each group at one year in the study eye

    M6-9

  • Progression of diabetic retinopathy in each group at one year according to the International DR classification in the study eye

    M13

  • Comparison of blood pressure in each group at one year

    M13

Study Arms (2)

intensive treatment

EXPERIMENTAL

with a systematic screening for sleep apnea and/or uncontrolled high blood pressure, and intensified intervention on both anomalies if detected

Interventions

over one 14 month period: strongly recommended hygiene-dietetic measurements, complete assessment with ambulatory measurement of the blood pressure in D0, 3 and 12 months, a therapeutic strategy according to the results, and control every 3 months

intensive treatment

over one 14 month period: complete assessment with night polysomnography in D0, 3 and 12 months, a therapeutic strategy according to the results, and control every 3 months

intensive treatment

over one 14 month period: control every 3 months, treatments by laser (focal or grid) are authorized until 9 months, treatments by injections are authorized until 6 months
