Filter by:This study will evaluate the safety and efficacy of OZURDEX® (700 µg dexamethasone implant) in patients with macular edema associated with branch retinal vein occlusion.
In this province, optometrists are often responsible for contacting the retinal specialists' office to arrange patients to be examined for suspected emergencies or more routine referrals related to the eye. This is often done by faxing a referral form to the specialists' office, where the retinal specialist will examine the information presented in the referral form and make a decision on when the patient should be seen. This current method has some important considerations, such as the difficulty of transmitting clear images of the back of the eye over fax. Having this information could help the retinal specialist in determining when the patient should be seen, especially in terms of booking additional tests or when treatment should be given. Teleophthalmology is a branch of telemedicine that delivers eye care through digital equipment and telecommunications technology. It offers some unique advantages, such as the ability to be integrated with electronic health records, the ability to be viewed by multiple members of the health care team, and potentially reduce wait times and travel times to the ophthalmologist. However, there is no comparison known to the study team between whether patients being referred from optometrists to retina specialists through a teleophthalmology system will be treated earlier than patients through a conventional fax system. This study aims to examine and provide more information on this topic.
Multicentre randomized controlled trial to evaluate whether 5 monthly fixed dosing of 700 µg Dexamethasone Posterior Segment Drug Delivery System (Ozurdex) is as efficacious as Optical coherence tomography (OCT)-guided PRN dosing in patients with refractory diabetic macular edema.
Diabetic Macular Edema (DME), which can happen as a complication of diabetes, occurs when fluid and proteins collect in the macula (the yellow central area of the retina). The fluid can cause swelling which in turn can lead to worsening central vision. The purpose of this study is to see if the study device (Swept Source Optical Coherence Tomography or SS-OCT) is able to diagnose DME as well as an already approved imaging procedure called fluorescein angiography (FA). FA is standard of care and would be conducted regardless of study participation. The dye used in FA, which can cause allergic reactions in some patients and is not used in pregnant women, is not needed with the study device. Another purpose of the study is to avoid the risk of administering the FA dye if possible.
The purpose of this protocol is to determine whether point of care optical coherence tomography (OCT) imaging combined with an OCT-guided retinal referral algorithm at primary diabetes care visits increases rates of retina specialist eye care for patients with diabetic macular edema. The hypothesis is that OCT imaging with an automated OCT-guided referral algorithm will enable identification of patients at risk for vision loss from diabetic macular edema and facilitate direct referral to retina specialists for more timely evaluation and treatment.
The purpose of this study is to determine whether an intravitreal dexamethasone implant (Ozurdex, Allergan) is effective to manage macular edema secondary to non-infectious uveitis.
The purpose of the study is to determine the effect of Intravitreal Aflibercept Injection (IAI) on previously treated Central Retinal Vein Occlusions (CRVOs) with other Anti-VEGF agents.
The purpose of this study is determine the number of patients with complete resolution of macular edema secondary to central retinal vein occlusion following 6 monthly injections of Aflibercept.
To evaluate the efficacy and safety of 0.5 mg in adult patients with visual impairment due to macular edema (ME).
This is an open-label, Phase I/II study of Intravitreally administered 0.3mg ranibizumab in subjects with persistent Diabetic Macular Edema (DME) after recent and frequent bevacizumab (at least 2 bevacizumab intravitreal injections within 2 months prior to enrollment and at least 6 bevacizumab injections within 9 months of enrollment).
