Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to evaluate the visual outcome and prognostic factors after intraocular injections of Ranibizumab or combination of Ranibizumab And Dexamethasone under pro re nata treatment regimen for Diabetic Macular Edema patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this study is to evaluate the clinical outcome after intraocular injections of Ranibizumab or combination of Ranibizumab and Dexamethasone under pro re nata treatment regimen for the patients with Diabetic Macular Edema patients. Mean change of logarithm of the minimal angle of resolution (logMAR) visual acuity (VA), central foveal thickness (CFT), contrast sensitivity (CS) as well as predictive factors including best-corrected visual acuity (BCVA), vision related questionnaires and various other ocular parameters will be assessed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Diabetic ME: Ranibizumab and intravitreal Dexamethasone

Participants with diabetic macular edema will receive a combination of Ranibizumab and intravitreal Dexamethasone

Group Type EXPERIMENTAL

Ranibizumab Ophthalmic and Intravitreal Dexamethasone

Intervention Type DRUG

Pro re nata patients with macula edema due to diabetes will receive Ranibizumab. Group A will continue to receive Ranibizumab depending on their clinical status of macular edema

Diabetic ME: Ranibizumab

Participants with diabetic macular edema (ME) will receive Ranibizumab only.

Group Type ACTIVE_COMPARATOR

Ranibizumab Ophthalmic only

Intervention Type DRUG

Group B will initially receive intravitreal Dexamethasone and Ranibizumab and then depending on their clinical status of macular edema, Ranibizumab will be injected.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Patients with diabetic retinopathy and centre involving DMO, as determined by using spectral domain optical coherence tomography (SD-OCT), in one or both eyes with:

1. Central retinal subfield thickness of \> 300 but \< 400 microns as determined by SD-OCT due to diabetic macular oedema OR
2. Central retinal subfield thickness of \< 300 microns provided that intraretinal and/or subretinal fluid is present in the central subfield (central 1 mm) related to diabetic macular oedema AND
3. Visual acuity of \> 24 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (Snellen equivalent \> 20/320)
4. Amenable to laser treatment, as judged by the treating ophthalmologist
5. Over 18 years of age

Exclusion Criteria

Eyes of patients will not be included in the study if:

1. The macular oedema is due to causes other than diabetic macular oedema such as epiretinal membrane, vitreomacular traction, vein occlusion, or others
2. The eye is ineligible for macular laser treatment, as judged by the treating ophthalmologist
3. The eye has DMO and central subfield retinal thickness (CST) of \> 400 microns.
4. The eye has activeA proliferative diabetic retinopathy (PDR) requiring treatment.
5. The eye has received intravitreal Anti- Vascular Endothelical Growth Factor (Anti-VEGF) therapy within the previous two months.
6. The eye has received macular laser treatment within the previous 12 months.
7. The eye has received intravitreal injection of steroids.
8. The eye has received cataract surgery within the previous six weeks
9. The eye has received panretinal photocoagulation within the previous 3 months
10. Patients on pioglitazone and the drug cannot be stopped 3 months prior to entering into the trial and for the duration of the study
11. The patient has chronic renal failure requiring dialysis or kidney transplant
12. The patient has any other condition that in the opinion of the investigator would preclude participation in the study (such as unstable medical status or severe disease that would make it difficult for the patient to be able to complete the study)
13. The patient has very poor glycemic control and started intensive therapy within the previous 3 months
14. The patient will use an investigational drug during the study
