Study Arms (2)

Prompt laser group

ACTIVE COMPARATOR

Eyes of eligible patients will be randomized (ratio 1:1) and receive ranibizumab and focal/grid laser on the same day (prompt' group, 25 eyes, 50%). Interventions: ranibizumab and focal/grid laser on the same day \[Ranibizumab (Ranibizumab 0.5 MG/0.05 ML Intraocular Solution\]

Drug: Ranibizumab 0.5 MG/0.05 ML Intraocular Solution

Deferred laser group

ACTIVE COMPARATOR

Eyes of eligible patients will be randomized (ratio 1:1) and receive ranibizumab and focal/grid laser on one week prior to laser treatment (deferred' group, 25 eyes, 50%). Interventions: ranibizumab and focal/grid laser on one week prior to laser treatment \[Ranibizumab 0.5 MG/0.05 ML Intraocular Solution\]

Drug: Ranibizumab 0.5 MG/0.05 ML Intraocular Solution

Interventions

Focal laser treatment will be performed using argon laser photocoagulation (VISULAS 532s®, Carl Zeiss Meditec) operating at 532nm and Ranibizumab 0.5 MG/0.05 ML Intraocular Solution. Ranibizumab 0.5 MG/0.05 ML Intraocular Solution

Also known as: Focal grid laser

Eligibility Criteria

Sexall(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • DME that will be detected clinically and on FA as well as on SD-OCT \[diffuse macular edema with central retinal thickness (CRT) ≥300µm involving the center of the macular area\]
  • Patients will be included into the present study following informed consent
  • Best-corrected-visual-acuity (BCVA) between 0.06 (1.2logMAR) and 0.63 (0.20logMAR).

You may not qualify if:

  • Eyes with other retinal diseases \[i.e. age-related macular degeneration (AMD) and associated choroidal neovascularization (CNV), cystoid macular edema (CME) of other origin (e.g. uveitis, Irvine-Gass syndrome, retinal vein occlusion), or retinal dystrophies\]
