A Retrospective Data Collection Study in Patients Receiving Dexamethasone Intravitreal Implant (Ozurdex®) for Macular Oedema Due to Retinal Vein Occlusion (RVO)

All participants

Patients who received at least two OZURDEX® (dexamethasone intravitreal implant) injections.

药品：地塞米松玻璃体内植入物 0.7 毫克

根据一般临床实践，预先给予地塞米松玻璃体内植入物 0.7 mg。

其他名称：

• OZURDEX®

Time to OZURDEX® Re-injection

Time to OZURDEX® re-injection is the time in days between the first and second OZURDEX® injections.

Change From Baseline in Best Corrected Visual Acuity (BCVA) 7 to 12 Weeks Following the Last Injection

BCVA was assessed using the Snellen eye chart converted to Early Treatment Diabetic Retinopathy Study number of letters ranging from 0 (worse) to 100 (best). The change in BCVA was calculated using the most improved number of letters read correctly between 7 and 12 weeks following the last injection of OZURDEX® - the number of letters read correctly at baseline. A positive change from baseline indicates improvement.

Percentage of Patients With an Increase of 2 Lines or More in BCVA

BCVA was assessed using the Snellen eye chart converted to Early Treatment Diabetic Retinopathy Study number of lines ranging from 0 (worse) to 20 (best). An increase of 2 or more lines read correctly compared to baseline is an improvement.

Percentage of Patients With an Increase of 3 Lines or More in BCVA

BCVA was assessed using the Snellen eye chart converted to Early Treatment Diabetic Retinopathy Study number of lines ranging from 0 (worse) to 20 (best). An increase of 3 or more lines read correctly compared to baseline is an improvement.

Change From Baseline in Central Retinal Thickness by Optical Coherence Tomography (OCT) 7 to 12 Weeks Following the Last Injection

Optical Coherence Tomography (OCT), a laser based non-invasive diagnostic system providing high-resolution imaging sections of the retina, was performed in the study eye after pupil dilation at baseline and 7 to 12 weeks after the last injection. A negative change from baseline indicates improvement.

Time to Improvement of 2 Lines or More in BCVA

Time to improvement of 2 lines or more in BCVA is defined as the number of days after the first injection of OZURDEX® to achieve an improvement of 2 or more lines read correctly compared to baseline. BCVA was assessed using the Snellen eye chart converted to Early Treatment Diabetic Retinopathy Study number of lines ranging from 0 (worse) to 20 (best).

Time to Improvement of 3 Lines or More in BCVA

Time to improvement of 3 lines or more in BCVA is defined as the number of days after the first injection of OZURDEX® to achieve an improvement of 3 or more lines read correctly compared to baseline. BCVA was assessed using the Snellen eye chart converted to Early Treatment Diabetic Retinopathy Study number of lines ranging from 0 (worse) to 20 (best).
