Spontaneous Retinal Artery Pulses (SPARs) as a Prognostic Determinant of Central Retinal Vein Occlusions (CRVO) in Patients With or Without Intravitreal Aflibercept Injections

An interventional study of Ophthalmologic exam at inclusion and 12 months after CRVO and Treatment standardization with aflibercept in Central Retinal Vein Occlusion, sponsored by Fondation Ophtalmologique Adolphe de Rothschild. Completed at 3 sites in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-04-30.

Study summary

Central retinal vein occlusion (CRVO) is the second most common retinal vascular disease after diabetic retinopathy. It induces circulatory slowdown and blood stasis, which can appear as retinal hemorrhages. CRVO has been classically separated into two clinical forms: ischemic CVRO (possibly associated with cotton wool spots) and non-ischemic CRVO, the former being considered the most serious due to neovascular complications. More recently, a new classification has been suggested by Pierru et al. distinguishing two types of CRVO: type A characterized by low acute blood flow and type B with a slower onset. Type A is particularly associated with younger age, the presence of acute paracentral middle maculopathy, concomitant cilioretinal artery occlusion, and/or pulsatile arterial filling. Type B is more likely to occur in elderly patients, usually with high blood pressure, and multiple hemorrhages are frequently found on fundus examination.

A retrospective study had shown a slight difference in favor of pulsatile CRVO in terms of the number of intravitreal anti-angiogenic injections required to treat macular edema and visual acuity changes. However, no statistically significant difference was observed.

The objective of this study is to prospectively investigate whether spontaneous retinal artery pulses (SPARs) in patients with type A or B CRVO can be considered as a prognostic factor for the evolution of CRVO.

Read the detailed description

In order to be able to interpret the results on a homogeneous population, given that several molecules have marketing authorization for the management of macular edema following a CRVO, the therapeutic management will be standardized by the use of aflibercept for patients requiring intravitreal injection, aflibercept being the most widely referenced treatment currently used in the participating centers.

What researchers measure

Primary outcomes

  1. Change in visual acuity between inclusion and visit at one year compared between patients with SPARs versus without SPARs

    Evolution of best corrected visual acuity on ETDRS scale (Early treatment diabetic retinopathy study scale) in letters read and validated Infrared movies will be made at inclusion from the Heidelberg Spectralis device. Two ophthalmologists blinded to each other will view the films. The arterial pulses are visualized at the optic disc site in the form of pulse-dependent beats of the arterial walls. For each movie each ophthalmologist will give his assessment: SPARs+ or SPARs-. In case of discrepancy, a third ophthalmological opinion will be requested.

    Time frame: At inclusion and 12 months after CRVO
