Multispot for peripheral treatment
Panretinal photocoagulation (PRP) has remained the standard of care for advanced diabetic retinopathy (DR) since the late 1970s, when the Diabetic Retinopathy Study (DRS) and the Early Treatment Diabetic Retinopathy Study (ETDRS) [1, 2] reported their benefit in blindness prevention in the proliferative stages of the disease.
Conventional single spot PRP is inherently destructive, nevertheless in the past decade new technologies have been introduced resulting in the development of a new generation of laser systems: Multispot Lasers. These are able to produce individual laser pulses shorter by an order of magnitude (0.01s-0,02s). At the same time these impulses are directed in a quick sequence one after another in so-called patterns.
Multispot laser photocoagulation is a novel method of delivering laser energy to the retina.
Before starting the laser treatment, the laser energy necessary for the production of one laser spot needs to be titrated (the pulse duration being shorter).
Thanks to a single spot, the laser energy is gradually increased until a grey laser spot is achieved.
The pattern can then be selected for treatment.
Multispot Treatment Guidelines
Characterized by the use of short pulse durations (10-20ms), the MultiSpot treatment mode offers many advantages over conventional photocoagulation in retinal treatments such as panretinal photocoagulation (PRP):
- Less heat diffusion to the retina and choroid, less damage to the retinal nerve fiber layer1,2
- Comfortable treatment better tolerated by patients3
- Extremely fast treatment (full PRP in 1 session)4.
The MultiSpot treatment mode can be delivered through 4 customizable patterns for better adaptation to the treatment site: Square, Circle, Triple arcs, Single Spot.
