Volk Optical’s Pictor Plus Portable Imager Used on Charitable Mission in Uganda

Handheld digital imager screened patients for diabetic retinopathy and pediatric retinoblastoma

Mentor, Ohio (July 9, 2015) – In April, Volk’s Pictor Plus was used by ophthalmologists from the Royal Free Hospital in London during a ten day charitable mission trip in Uganda. Volk’s Regional Manager for Europe, Terry Cooper, joined the Vision 2020 LINKS team, a group led by ophthalmologist Clare Davey, on a mission to reduce preventable blindness. The Pictor Plus was the only fundus camera available to the team and was used primarily for screening for diabetic retinopathy and examinations under anesthetic of retinoblastoma patients.

The trip included clinics held at the Mulago Referral Hospital in the capital city of Kampala, as well as at Ruharo Eye Centre, in the far more remote city of Mbarara. The Pictor Plus handheld digital imager is ideal for mission and field work, delivering high quality retinal views in a compact device that weighs in at just one pound. For the mission trip, the Pictor Plus, its accessories, and a laptop with image capture software travelled in a standard sized backpack outfitted with a solar panel for field use and mobile battery recharge.

“I first learned about the Uganda trip when I met Clare Davey at a Congress,” explained Cooper. “As I learned the scope of the project, I realized that Pictor Plus would be great tool for the physicians on this mission. What’s more, I have a personal interest in charitable activities, so my involvement on Volk’s behalf really came together organically.”

With a 40° by 45° field of view of the fundus and two modules for both retinal and anterior anatomy imaging, clinicians were able to identify a range of patient pathologies. All stages of diabetic retinopathy, as well as serious conditions such as BRVO (Branch Retinal Vein Occlusion) and CRVO (Central Retinal Vein Occlusion) were seen. It was also used to examine retinoblastoma patients–particularly critical as the incidence of this childhood cancer in Uganda is nearly twice that of the UK (1-2 cases referred per week at just one hospital in Uganda, compared to 45 per year total in all the UK).

Typically during screenings at the Mulago Referral Hospital, four fundus images were taken of each patient with Pictor Plus: disc-centered and macula-centered, of each eye. The Pictor Plus’ eyecup provided stability to the camera, reduced stray light and generally helped team members get good images. Images were then transmitted wirelessly into Health Intelligence’s Spectra Retineye screening software for review by an ophthalmologist. Those with abnormal retinal findings were then further examined with optical coherence tomography (OCT) and treated with laser as appropriate.

Cooper and the Pictor Plus then travelled to the Ruharo Eye Centre of the Ruharo Mission Hospital to work with ophthalmologist Keith Waddell. During the visit, the Pictor Plus was used for examination under anesthetic of retinoblastoma patients. It enabled the team to take fundus images of children ranging in age from two months to 12 years old with relative ease, running on its own solar power, rather the unreliable local power.

“It’s personally gratifying to have this opportunity as a part of Volk-to be able to share portable technology that can be used effectively in developing countries,” said Cooper. “The dire lack of eye care resources and infrastructure means people go needlessly blind.”

For team leader Davey, having a member of the team from the optical industry was especially helpful. “This visit was particularly successful because we had a very defined remit, because we have already established good working relationships with the team in Mulago, and because for the first time we had a member from the optical industry (Terry Cooper) who set up the equipment, optimized its use and helped train the local staff,” she said. “I recommend similar Vision 2020 visits to concentrate on taking the most effective team.”

MidVitreous Lens for Vitreolysis Applications

Volk Optical’s Idrees MidVitreous Lens specifically designed for elimination of floaters

Mentor, Ohio (May 11, 2015) –Volk Optical’s new Idrees MidVitreous lens provides high resolution views and maximum focusing ability to reduce required laser energy during vitreolysis treatment.

IdreesReleaseBLOG

Developed in collaboration with Dr. Mohammed Idrees of the Saudi German Hospital (Riyadh, Saudi Arabia), the lens was designed specifically for elimination of vitreous strands or opacities in the central mid-vitreous. With a 1.11x image magnification, and .90x laser spot, the Idrees MidVitreous Lens provides the highest resolution and focusing ability of any commercially available vitreolysis lens. Less laser energy is required for treatment, improving patient safety.

The flanged contact provides stability for laser delivery and prevents patients from squeezing it off the eye. The large ring diameter (36mm) and tall lens body allow for easy manipulation within the orbit, particularly in patients with deep set eyes. The direct contact lens requires the use of viscous coupling fluid during laser treatment.

Accurate Ocular Measurements with the Volk Eye Check

Volk Optical’s Eye Check, an electronic handheld ocular measurement device, aids in the diagnosis of ophthalmic abnormalities. Capable of a number of key measurements including pupil diameter, horizontal visible iris diameter, interpupillary distance, margin reflex distance, pupil eccentricity and strabismus angle, Eye Check helps practitioners screen and document ocular characteristics for contact lens fitting and general diagnostic purposes.

The Eye Check’s intuitive user interface is easily navigated by physicians and support staff for seamless integration into the practice environment. Its real-time, accurate and objective results enable quick decision making and can be output to electronic records management systems with WiFi connectivity.
Eye Check can help to quickly identify patients that are candidates for specialty lenses and reduce practice drop out rates.

Eye Check measurement parameters that facilitate lens fitting are:
• Horizontal Visible Iris Diameter (HVID) to assess correct contact lens diameter
• Pupil diameter and eccentricity for GP lens fitting and multi focal contact lens choice
• Lid margin to pupil margin for bifocal lens fitting

For general diagnosis and documentation, Eye Check also measures:
• Interpupillary distance for eyeglass fitting
• Margin reflex distance for detection and documentation of ptosis in endocrine disorders, as well as pre- and post-surgical comparison
• Strabismus angle for Amblyopia and Strabismus screening with objective documentation of strambismus amplitude

New Iridotomy Lens with Unique Features

Volk Optical has launched a new specialty lens for iridotomy procedures. Developed in conjunction with Eytan Blumenthal MD, the Blumenthal Iridotomy Lens design increases access to the periphery for more efficient glaucoma treatment with less potential for damage to surrounding tissues.

The design of the contact lens indents the cornea to open the angle and flatten the peripheral iris, delivering better patient outcomes with less post-laser inflammation. The Blumenthal Iridotomy’s precise positioning and sharply focused laser spot minimizes iris tissue collateral damage and distances the cornea from the iris to reduce the risk of endothelial cell damage.

The Blumenthal Iridotomy lens improves over classic lenses, as it is the only lens with corneal indentation capability for enhanced viewing of the far periphery. Constructed using Volk’s patented aspheric optics, the lens delivers better image quality and improved laser burn. Lower energy is required, reducing thermal collateral damage. The large lens housing improves lens grip and alignment for oblique viewing of the entire chamber.

Eytan Blumenthal, MD is Chairman of the Department of Ophthalmology at Rambam Health Care Campus (Hafia, Israel). This is his second lens collaboration with Volk.

4 Mirror Gonio Lens Options

When considering a 4 mirror lens for gonioscopy, there are a number of options available to you:

1) The Volk 4 mirror lens is now available in 2 magnification levels
a. Traditional magnification of 1.0x; does not alter the size of the structure you are viewing
b. High magnification of 1.5x provides a much higher level of detail in the anterior chamber

2) Contact options
a. Flanged version which requires a coupling fluid and provides superior stability
b. No flange version does not require the fluid and reduces time to apply the lens and examine

3) Holding options
a. Small or large ring keeps your hand close to the patient’s brow – can help stabilize the lens
b. A 2 position angle (straight and 45°) keeps your hand away from the patient’s face

The Volk 4 mirror has consistently positioned mirrors at 64° and is an all glass lens providing the finest image quality of the chamber angle.

Cleaning Volk Lenses

When cleaning lenses, a good practice is to rinse under tap water to remove particulate which can scratch the lens coating and glass. A mild detergent and water is ideal to clean the surface.

Clean your lens one side at a time in a clock wise direction. Cleaning in a counter clock wise direction may loosen the glass element from the ring.

Do not use micro fiber clothes as they will remove the coating over time.

Do not air dry your lens as water droplets left on the surface of the lens will case damage to the coating. Clean and Dry with a lint free cotton cloth to avoid damage.
