Manage Macular Cystoid Edema With Retinal Vein Obstruction Using Traditional Chinese Medicine and Ranibizumab (JQMMT+RA)

August 18, 2025 updated by: Zhou Hangshuai, Dongyang People's Hospital

Traditional Chinese Medicine and Ranibizumab in the Treatment of Macular Cystoid Edema Associated With Retinal Vein Obstruction.

The objective of this study was to investigate the efficacy and safety of traditional Chinese medicine (Jueling Mingmu Decoction) combined with ranibizumab in the treatment of macular edema with retinal vein obstructive.

Study Overview

Detailed Description

Compared to the sole intravitreal injection of ranibizumab, the combined use of traditional Chinese medicine with intravitreal ranibizumab aims to determine if it is more effective in alleviating macular cystoid edema secondary to retinal branch vein occlusion, leading to improved visual prognosis and potentially reducing the frequency of intravitreal drug injections.

Intervention / Treatment
Experimental: Combination Therapy Group

During the initial month, the patient consumed Jueling Mingmu decoction daily for one month.

Patients received monthly intravitreal injections of 0.5mg ranibizumab for the initial three months, followed by additional injections in the subsequent nine months for those who met eligibility criteria.

Jueling Mingmu decoction comprises stone cassia, grass cassia, Leonurus, chrysanthemum, red peony, Schizonepeta, poria, plantago, salvia miltiorrhiza, rice bud, licorice. It is designed to clear liver heat, promote diuresis, activate blood circulation, strengthen the stomach, and harmonize spleen functions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mean number of injections
Time Frame: 48 weeks
We will calculate the mean number of intravitreal ranibizumab injections at week 48.
48 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in BCVA
Time Frame: 48 weeks
We will assess the participants' best-corrected distance visual acuity by ETDRS charts before and after the treatment at weeks 48.
48 weeks
The mean change of central retinal thickness (CRT).
Time Frame: 48 weeks
The participants' eyes will be fully dilated; the examiner will take the macular fovea as the center and perform a multi-directional, 6 mm-long, radial linear scan of the most prominent macular lesions and take linear scans in the same direction after the treatment. CRT is defined as the distance between internal limiting membrane and external limiting membrane, excluding the fluid under the retinal pigment epithelium (RPE).
