Outcomes

Primary Outcomes

Mean Number of OZURDEX® Implant Reinjections in the Study Eye

Study eye was defined as the eye that received the most OZURDEX® injections.

Time frame: Up to 44 months

Time to OZURDEX® Reinjection

The time to reinjection is defined as the time in months from the date of one OZURDEX® injection to the subsequent OZURDEX® injection.

Time frame: Up to 44 months

Secondary Outcomes

Change in Best Corrected Visual Acuity (BCVA) From the Last Assessment Prior to Each OZURDEX® Implant Injection to 7-12 Weeks Following Each OZURDEX® Implant Injection

BCVA is measured in the study eye (defined as the eye that received the most OZURDEX® injections) following each injection of OZURDEX® using a special eye chart and is reported as number of letters read correctly (ranging from 0 to 100 letters). The lower the number of letters read correctly on the eye chart, the worse the vision. The higher the number of letters read correctly, the better the vision. A positive number indicates improvement. Change data are reported for each injection relative to the assessment immediately prior to the injection to 7 to 12 weeks following that injection.

Time frame: Last assessment prior to each OZURDEX® injection, 7 to 12 weeks following each injection

Change From Baseline in BCVA From the Last Assessment Prior to the First OZURDEX® Implant Injection to 7-12 Weeks Following Each OZURDEX® Implant Injection

BCVA is measured in the study eye (defined as the eye that received the most OZURDEX® injections) following each injection of OZURDEX® using a special eye chart and is reported as number of letters read correctly (ranging from 0 to 100 letters). The lower the number of letters read correctly on the eye chart, the worse the vision. The higher the number of letters read correctly, the better the vision. A positive change from baseline indicates improvement. Change data are reported for each injection relative to the assessment prior the first injection to 7 to 12 weeks following each injection.

Change in Central Retinal Thickness (CRT) by Optical Coherence Tomography (OCT) From the Last Assessment Prior to Each OZURDEX® Implant Injection to 7-12 Weeks Following Each OZURDEX® Implant Injection

OCT is measured in the study eye (defined as the eye that received the most OZURDEX® injections) prior to and following each injection of OZURDEX®. OCT is a laser based non-invasive diagnostic system providing high-resolution imaging sections of the retina to assess retinal thickness. A negative change indicates an improvement. Change data are reported for each injection relative to the assessment immediately prior to the injection to 7 to 12 weeks following that injection.

Time frame: Last assessment prior to each OZURDEX® injection, 7 to 12 weeks following each injection

Change From Baseline in CRT by OCT From the Last Assessment Prior to the First OZURDEX® Implant Injection to 7-12 Weeks Following Each OZURDEX® Implant Injection

OCT is measured at Baseline and following each injection of OZURDEX® in the study eye (defined as the eye that received the most OZURDEX® injections . OCT is a laser based non-invasive diagnostic system providing high-resolution imaging sections of the retina to assess retinal thickness. A negative change indicates an improvement. Change data are reported for each injection relative to the assessment prior the first injection to 7 to 12 weeks following each injection.

Time frame: Baseline (Last assessment prior to the first OZURDEX® injection), 7 to 12 weeks following each injection

Percentage of Participants Who Experienced At Least One Adverse Events of Special Interest (AESIs)

An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a drug whether or not it is considered related to the drug. The adverse events of special interest include: Glaucoma, defined as damage to the optic nerve with progressive vision loss, Intraocular hypertension, defined as intra-ocular pressure (IOP) without meeting the criteria for glaucoma, Hypotony, defined as low IOP ≤5 mmHg, Cataract or lens opacities, Ocular bleeding or hemorrhage, Retinal detachment, tear or hole, Vitreous detachment, Infection vs. Non-infection related Ocular inflammation, Significant vitreous loss, Mechanical failure of device and implant misplacement, Implant dislocation.

Time frame: Up to 44 months
