PRP Retreatment in PDR

Baseline PRP Retreatment of PDR with Navilas

Baseline

A 45-years old patient with proliferative diabetic retinopathy (PDR) is showing severe typical signs of PDR on FA images, e.g. neovascularisation and leakages at the optic nerve head and microaneurysms and microhemorrhages.

Individual treatment approach of  Dr. Emiliano Di Carlo, Department of Ophthalmology, Staedtisches Klinikum Karlsruhe, Germany
Plan PRP Retreatment of PDR with Navilas

Treatment

Two separate patterns were preplanned, one for each nasal quadrant. Caution zones were set on particularly sensitive areas (macula and optic nerve head). Blood vessels were spared using the Navilas unique eraser function.

Outcome PRP Retreatment of PDR with Navilas

Outcome

A total of 553 spots were applied in one session using two preplanned grids. The distribution of laser spots and gaps between spots is very uniform. Due to Navilas technique, laser spots are equal in size and without distortion in the far periphery.

    Subthreshold CSCR Treatment

    Baseline

    A 59 year old female presented in our offices with blurred vision during "a couple of months“ and was diagnosed with an acute episode of Central serous chorioretinopathy. Her BCVA was 20/40. We took an observation period of around two months followed to allow a spontaneous resolution. Due to unchanged size of edema after this observation period the patient was scheduled for microsecond pulsing laser.

    Treatment

    The microsecond pulsing laser treatment was planned using en face OCT image. We targeted flat RPE elevation in upper part of neuroepithelium detachment and covered it with 98 confluently planned laser spots (100 µm). Treatment parameters were 200 ms, 400 mW and 5% duty cycle.

    Outcome

    About 2 months after laser treatment the subretinal fluid completely resolved and BCVA increased from 20/40 to 20/25.

      Subthreshold DME Treatment

      Baseline Subthreshold DME Case

      Baseline

      A 61years-old patient with proliferative diabetic retinopathy is showing a decreased visual acuity of 20/250 and a refractory macular edema, not responding to Anti-VEGF injections.

      Planning Subthreshold DME Case

      Treatment

      On basis of an imported external OCT image, a confluent subthreshold pattern over the most thickened area was planned. Caution zones were placed directly on the macula and on the optic nerve head to prevent healthy and sensitive tissue from getting damaged. Titration was performed in continuous wave mode outside of the vessel arcs, microsecond pulses were used with 10% duty cycle, power was doubled after creating a barely visible burn while titrating.

      Reporting Subthreshold DME Case

      Reporting

      As microsecond pulses were used in a subthreshold treament manner, burns are not visible on the retina. Therefore, it´s impossible to see the treated areas. Only Navilas unique report function allows a documentation by marking treated areas and showing used parameters.

      Individual treatment approach of   Dr. Emma Tsarukyan, Ophtalmological Center After S.V.Malayan, Yerevan, Armenia
      Outcome Subthreshold DME Case

      Outcome

      Three months after Navilas microsecond pulsing treatment, a significant reduction of DME was shown on OCT macula thickness map and a significantly increased visual acuity from 20/250 up to 20/40 was shown.

        Success with Microsecond Pulsing in a Patient with Recurrent CSCR and Subfoveal Leakage

        Dr. Wolf Baseline

        Baseline
        Blue laser autofluorescence (BAF), early phase fluorescence angiography (FA) and indocyanin green angiography (ICGA) images were used to detect the source of subfoveal leakage for a patient with recurrent CSCR.

        Dr. Wolf Treatment

        Treatment
        A confluent pattern with microsecond pulses was placed covering the leakage source of the CSCR subfoveal fluid. Caution zones were placed over healthy and sensitive tissue. Titration was performed in continuous wave mode outside of the large vascular arches.

        Dr. Wolf Outcome

        Outcome
        After one single Navilas MSP laser therapy, the subfoveal edema resolved completely within a time period of 12 weeks.

          Treating a Retinal Tear in the Far Periphery without LIO

          Non-LIO treatment of a retinal tear using navigated laser

          Baseline

          A female patient presented with several retinal tears due to lattice degeneration in both eyes (left eye treated before on LIO, right eye schedule for a second visit). Due to significant pain during the treatment of the left eye the patient asked for alternatives to LIO.

          Outcome

          Despite very far position of retinal tears, lesions could easily be encircled with spots. No switch to LIO was necessary. The patient was compliant during all the procedure and clearly commented on much higher tolerability as compared to the LIO. The patient stated that she is clearly preferring the treatment on Navilas as compared to the LIO. 

          Individual treatment approach courtesy of Dr. Neesurg Mehta, NYEE, New York, US

            "Although we did not feel that the Navilas could provide adequate treatment for laser retinopexy, due to the patient's significant discomfort while using the LIO, we decided to use the Navilas. After the treatment, everyone was surprised as to how quickly it was performed and how comfortable the patient was during the procedure. We now understand why Navilas does not provide an LIO adapter."

            Microsecond Pulsing Treatment in Branch Vein Occlusion

            Baseline

            A male middle-aged patient presented with severe BRVO. Little to no improvement was achieved despite several anti-VEGF injections. A single µs treatment was attempted to reduce injection burden.

            Individual treatment approach courtesy of Dr. Wayne Solley, Texas Retina, Arlington, TX

            Treatment

            The treatment plan was outlined as confluent grid covering thickened area (100µm, 100ms). After titration in continuous wave mode (endpoint barely visible burn) and switch to 10% Duty Cycle with the same power as in titration.

            Individual treatment approach courtesy of Dr. Wayne Solley, Texas Retina, Arlington, TX

            Outcome

            During the 3 month follow up the patient returned with significant reduction of edema and an improved best corrected visual acuity to 20/52-1

              Individual treatment approach courtesy of Dr. Jay Chhablani, LV Prasad Eye Institute.

              Treatment

              Treatment was performed with a confluent 3x3 grid. Parameters were adjusted to 5%DC, 100µm & 100ms. Titration was done in microsecond mode and power turned down to 30%.

              Individual treatment approach courtesy of Dr. Jay Chhablani, LV Prasad Eye Institute.

              Outcome

              On the 4 month follow-up, patient presented with completely resolved subretinal fluid and improved vision from 20/25 to 20/20.

                  Treatment

                  Using a Navilas FA image the treatment was planned to specifically target teleangiectasia and the adjacent area. Navigated treatment was performed using 120µm, 100ms, 100mW.

                    Treatment

                    Bilateral image-stabilized treatments were planned directly on Navilas FA: Subthreshold treatment of perifoveal disease within 500 microns from the foveal center and threshold treatment of all extrafoveal microaneurysms.

                    Outcome

                    The perifoveal swelling in the left eye disappeared. SD-OCT after Navilas showed resolution of macular edema as compared to pre-operative OCT. 3 months after treatment the VA improved to 20/20 OU and the patient was symptom-free.
