Conditions

Diabetic Macular Edema

Brief summary

The purpose of this research study is to determine if a Treat and Extend regimen (increasing the time between visits when the disease is stable and not getting worse) of Ranibizumab 0.3 mg injections inside the eye is safe and effective at treating patients with swelling of the retina from diabetes.

Detailed description

This research study will compare the visual outcomes between a group of patients who are treated with monthly injections of Ranibizumab 0.3 mg and two groups of patients who are treated with the Treat and Extend regimen. One of the Treat and Extend groups will also receive laser therapy to determine if this has any additional beneficial effects.

Inclusion criteria

* Ability to provide written informed consent and comply with study assessments for the full duration of the study * Age \> 18 years of age Patient related considerations * For sexually active women of childbearing potential, agreement to the use of an appropriate form of contraception (or abstinence) for the duration of the study * Although no birth control method is 100% effective, the following are considered effective means of contraception: surgical sterilization, use of oral contraceptives, barrier contraception using either a condom or diaphragm with spermicidal gel, an intrauterine device, or contraceptive hormone implant or patch. A patient's primary care physician, obstetrician, or gynecologist should be consulted regarding an appropriate form of birth control. * Ability and willingness to return for all scheduled visits and assessments Disease related considerations * The presence of center-involving diabetic macular edema on clinical exam and SDOCT * Best corrected visual acuity in the study eye, using ETDRS testing, between 20/25 and 20/320 (Snellen equivalent), inclusive. * Clear ocular media and adequate pupillary dilation to permit good quality fundus imaging.

At the fourth visit (Week 12), if the central foveal thickness is ≤ 325 μm then the eye will receive 0.3 mg ranibizumab and begin the extension phase of the study. For all subsequent visits in the extension phase, appropriate changes to the treatment interval with 0.3 mg ranibizumab (i.e. extend, maintain, reduce) will be made based on pre-specified SD (Spectral Domain)-OCT criteria. Treatment is rendered at every visit. The time between visits is individualized based on each subject's response to treatment. If the central foveal thickness is \> 325 μm at week 12, then the patient will continue to receive monthly intravitreal injections of 0.3 mg ranibizumab until the central foveal thickness is ≤ 325 μm.
