    Easier ways to identify compromised corneas

    Detection of dry eye, allergy, conjunctivitis leads to earlier treatment of disease states

    Over the past few years, various diagnostics have been introduced to help clinicians identify inflammatory conditions on the ocular surface more readily and, therefore, provide treatment to patients earlier in their disease states.

    Dry eye

    Clinicians “need to understand, there’s no magic bullet,” said Ernest W. Kornmehl, MD, of Kornmehl Laser Eye Associates, Brookline, MA. Each of the innovations that has been introduced—from topical cyclosporine 0.01% (Restasis, Allergan) to LipiFlow (TearScience)—is not the sole thing that will help a patient, he noted.

    Dry eye disease is multifactorial and as a result, specialists must employ multiple modalities to achieve satisfactory results for patients, he said.

    The next few years will most likely be a pivotal point in time for ocular surface disease and its impact on vision correction, predicted Jonathan H. Talamo, MD, of Mass. Eye and Ear, Boston.

    About 80% of patients suffer from evaporative dry eye as opposed to aqueous-deficient dry eye, so treatment advances in the evaporative sector, such as thermal pulsation of meibomian gland disease (LipiFlow), have great impact.

    “It’s not that 2015 had so many new innovations per se, but [with] many things that have been developed over the past few years, the ophthalmic community is beginning to get a better understanding of them and better understanding of the appropriate utilization,” he said.

    It is likely 2015 will be remembered more for its pivot in “attitude, effort, and investment toward new strategies for drug delivery to the front of the eye,” he said, most of which comes from the success of using biologics in retinal disease. “It’s raised awareness of conditions like glaucoma, dry eye, and other ocular surface/anterior segment conditions and made us as eye specialists realize that the therapies we have, while sometimes adequate, are far from ideal.”

    New and better metrics to aid in diagnosing and therapeutic monitoring have gained market acceptance and will continue to do so, Dr. Talamo said, including the tear film osmolarity device (TearLab) to gauge whether someone has dry eye.

    While the Sjo test identifies a systemic disease (Sjogren’s), the InflammaDry is a metallic matrix metalloproteinase (MMP-9) marker (Rapid Pathogen System). Dr. Kornmehl said the two are useful in certain situations, but may not be optimum practice to use on every patient.

    Dr. Talamo said the surge in the popularity of the InflammaDry device is partly due to the fact that it is most clinicians’ initial strategy to help differentiate whether or not someone’s dry eye symptoms have an inflammatory component. While qualitative, Dr. Talamo hopes next-generation tests may be qualitative as well.
