Clinical Trial Summary

The purpose of this study is to compare two different treatment protocols for wet macular degeneration; the new protocol called "Observe and Plan" against the current standard protocol "Treat and Extend". Studies suggest that patients achieve equally good visual acuity with fewer controls and that they are more satisfied with the new protocol.

Description:

The purpose of the study is to test a new treatment protocol for wet macular degeneration, called "Observe and Plan", against today's standard protocol "Treat and Extend". Studies suggest that the individual treatment interval can be achieved earlier with "Observe-and-Plan" and that a proportion of patients do not need more than 3 injections, ie the loading dose. The other advantages seem to be that patients achieve good visual acuity with fewer controls and are more satisfied with the new protocol, which will be beneficial to both patients and health care. To our knowledge, no randomized controlled trial has tested this before.

Intervention

Other:
• Observe and Plan
First the individual interval between the injections of anti-VEGF (vascular endothelial growth factor) is established by observing the time from the loading dose to recurrence of the disease. The patient will come to control every four weeks to establish this interval. Second, the patient will receive injections at intervals that are two weeks shorter than the observed period. 2-3 injections are given before the next control. The control should be no later than six months ahead.
• Treat-and-Extend
At the first control 4 weeks after the loading dose, the ophthalmologist assesses whether the macula is still wet or whether the macula is dry. In case of wet macula, the patient receives a new injection on the same day and a new control in 4 weeks. If the macula is dry, the patient will return in 2 weeks for the next injection, ie the injection interval is extended from 4 to 6 weeks. Patients will be controlled every time they are to receive an intravitreal injection. If the macula is dry, the injection interval will be extended by 2 weeks and if the macula is wet the interval is shortened by 2 weeks. The shortest interval will be 4 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual acuity	Number of letters read at the ETDRS chart will be tested for each eye starting with a test distance of 2 meter, after correction of the refraction. A standardized testing protocol will be used both for refraction and the visual acuity test.	1 year

Secondary	Patient satisfaction assessed by NEI-VFQ-25	National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25). The VFQ-25 is a reliable and valid 25-item version of the 51-item National Eye Institute Visual Function Questionnaire (NEI-VFQ). It is especially useful in settings such as clinical trials, where interview length is a critical consideration.	1 year
