    Helping patients through the dry eye season


    Flu vaccines are created to protect against the three or four viruses that research suggests will be most common for the coming season. For the 2017-2018 season, three-component vaccines are recommended to contain:

    • An A/Michigan/45/2015 (H1N1)pdm09-like virus (updated)

    • An A/Hong Kong/4801/2014 (H3N2)-like virus

    • A B/Brisbane/60/2008-like (B/Victoria lineage) virus

    Quadrivalent, or four-component, vaccines, protect against a second lineage of B viruses. These are recommended to be produced using the same viruses recommended for the trivalent vaccines listed above as well as a B/Phuket/3073/2013-like (B/Yamagata lineage) virus.3

    How to help

    In an effort to reduce infection rates, wash everything. Washing hands, surfaces, basically everything, and covering ones month when coughing is highly recommended.

    It is also beneficial to increase the humidity in the air. The majority of adverse health effects caused by relative humidity would be minimized by maintaining indoor levels between 40 and 60 percent.4 This requires humidification of the air daily using evaporative or steam humidifiers. Cool mist humidifiers should not be used because they can disseminate allergens and aerosol contaminants.     

    Vaporizers can be used at night, but they must be placed where the steam will not injure anyone by being stepped on in the dark. Placing bowls of water around the home or office space and refilling them as needed is also beneficial and inexpensive. I send my patients to the dollar store for $1 vases and decorative stones or beads, which make great humidifiers when filled with water.

    Humidification is important for ocular surface disease treatment as well. Patients may not understand they need to increase tear supplements. Regular usage of tears and medications is critical.

    Educating patients

    I discuss dry eye season with my patients year round. Be proactive about dry eye treatment during this time period. I educate my patients what to expect during dry eye season all year, and I plan their return to office during this time. I have as many current dry eye patients as possible return to see me in late November and early December. For those who are new to my practice, I may see them several times over this period to ensure they are improving and comfortable.

    I also educate patients that controlling dry eye in the winter months may be an uphill battle, and they are more likely to be symptomatic. I tend to be more aggressive with treatments during this time. For example, if I want to initiate treatment of meibomian gland dysfunction in June, I explain that we are going to supplement with omega-3 fatty acids and start regular use of lipid-containing tears. I would consider adding topical azithromycin or oral doxycycline if treatment was initiated in October, given we are moving into the drier season.

    If starting treatment in December, I mention that if the patient does worsen over the next few months, that is actually an improvement, not a treatment failure. This is because it is more difficult to control symptoms during this time of year. Education is especially important for those undergoing cataract surgery or refractive surgery because ocular surgery may increase ocular surface disease.

    This season can be a problem for contact lens wearers as well if the drier air prevents them from wearing their contact lenses comfortably. Some may discontinue wear completely during this time. For this reason, I mention dry eye season to this patient population as well.

    Finally, I try to see as many patients who call with ocular complaints during dry eye season. They stay with you forever if you give them happier eyes for the holidays.
