Editor's Commentary - Jason J. Nichols, OD, MPH, PhD, FAAO
I am often surprised how frequently we don’t try new things—in terms of contact lens material and design options. Perhaps we are all stuck in our ways, but I think it is important to step out of the box. I am very proactive in teaching students, interns and residents that they should be constantly trying new contact lens options in their patients. If nothing else, we can often learn how easy or better a new option might be. And, ultimately this would no doubt be of benefit to our patients.

NIH Grant for BLINK Study
Investigators at University of Houston (UH) and The Ohio State University (OSU) Colleges of Optometry were awarded grants from the National Institutes of Health (NIH) National Eye Institute, worth approximately $7.5 million over five years. The Bifocal Lenses In Nearsighted Kids (BLINK) Study is a multicenter randomized clinical trial that will follow nearly 300 children over the course of three years.

Children 7 to 11 years old will be enrolled and randomly assigned to wear soft contact lenses with no reading power, soft contact lenses with medium reading power or soft contact lenses with high reading power. The investigators will measure the length of the eye and the amount of nearsightedness to determine whether light focused by the reading power of the soft bifocal contact lenses in front of the retina will result in slower eye growth and, thus, slower progression of nearsightedness.

Members of the study team are BLINK Study chair and OSU associate professor Jeffrey J. Walline, OD, PhD; OSU professor Donald O. Mutti, OD, PhD, the Clinic Principal Investigator at OSU; David A. Berntsen, OD, PhD, the Clinic Principal Investigator at UH; and Lisa A. Jones-Jordan, PhD, the Director of the Data Coordinating Center at OSU.

The investigators plan to begin enrollment this summer and complete recruitment within one year.

CARE SOLUTION CORNER
Susan J. Gromacki, OD, MS, FAAO

Report from the Ophthalmic Devices Panel of the Medical Devices Advisory Committee
Despite new lens materials and solutions, the FDA has not updated its guidance since 1997 – seventeen years ago. On May 13, 2014, I had the privilege of representing the American Academy of Optometry at the FDA-convened Ophthalmic Devices Panel of the Medical Devices Advisory Committee. The purpose of the meeting was for the FDA to present its proposed changes to the Contact Lens and Care Product Guidance Documents and to ascertain input from the panel, which included optometrists, ophthalmologists, scientists, and consumer and industry representatives.

Members of the FDA spoke on their organization’s proposed changes in the following topical areas:

1. Grouping scheme for silicone hydrogel lenses
2. Clinical test matrix for contact lens care products with silicone hydrogel lenses
3. Screening solutions for lens preservative uptake and listing incompatible lenses in solution labeling.
4. Testing under “real world” conditions, including adding soil; extending the soaking time; and measuring lens uptake.
5. The use of water with gas permeable (GP) lenses.

I will discuss these topics in greater detail in my next column.

OCULAR SURFACE UPDATE
Katherine M. Mastrota, MS, OD, FAAO
Meibomian Gland Loss Secondary to Trabeculectomies
In my practice, we have a very large number of patients referred for glaucoma: many cases are recalcitrant to treatment. Our glaucoma surgeon has performed thousands of successful trabeculectomies. In all likelihood, many of these patients spent years using multiple glaucoma medications, known to compromise the environment of the ocular surface.

Mitomycin C, a chemotherapeutic used at the time of trabeculectomy surgery, helps prevent scarring that causes bleb failure by inhibiting fibroblast proliferation. A recent study from Japan investigated meibomian gland loss secondary to trabeculectomies with mitomycin C.

This cross-sectional observational case study used a mobile pen-shaped noncontact meibography system to access the morphology and determine loss of the meibomian glands. Meibomian gland loss was scored in the bleb-contacting and bleb-noncontacting upper eyelid areas in the primary position and in the lower eyelid. The median duration from trabeculectomy to examination was 7.4 years. The results of this study demonstrated that blebs after trabeculectomy with MMC may be the cause of meibomian gland loss, particularly when the bleb is avascular. The authors suggest that the presence of an avascular bleb warrants extra vigilance for decreased meibomian gland secretions because this decrease can lead to tear dysfunction and ocular surface damage, including bleb-wall damage.

A Randomized Controlled Trial Comparing SCL and RGP Lens Wearing in Infantile Nystagmus

The objective of this study was to perform the first randomized controlled trial comparing soft contact lens (SCL) with rigid gas-permeable lens (RGPL) wearing in infantile nystagmus (IN), using spectacle wear as a baseline.

This was a randomized, controlled cross-over trial with an intention-to-treat design. The study included a total of 24 participants with IN (12 idiopathic, 12 with albinism). Participants were randomized into one of two treatment arms receiving the following sequence of treatments (2-3 weeks for each treatment): (A) spectacles, SCL, RGPL, and spectacle wear; or (B) spectacles, RGPL, SCL, and spectacle wear.

The main outcome measure was mean intensity of nystagmus at the null region viewing at 1.2 m. Secondary outcome measures included the same measure at 0.4 m viewing and across the horizontal meridian (measured over a ±30° range at 3° intervals) for distance and near. The nystagmus foveation characteristics were similarly assessed over ±30° and at the null region at 1.2 m and 0.4 m viewing. Visual outcome measures included best-corrected visual acuity (BCVA) at 4 m and 0.4 m, gaze-dependent visual acuity (GDVA) (i.e., visual acuity when maintaining gaze angles over a ±30° range at 10° intervals) at 4 m, and reading performance at 0.4 m derived from the Radner reading chart.

There were no significant differences between SCL and RGPL wearing for any nystagmus characteristics or compared with spectacle wearing. The BCVA, reading acuity, and critical print size were significantly worse for SCL wearing compared with RGPL and baseline spectacle wear (P<0.05), although mean differences were less than 1 logarithm of the minimum angle of resolution (logMAR) line.

The researchers concluded that nystagmus was not significantly different during SCL and RGPL wearing in IN, and contact lens wearing does not significantly reduce nystagmus compared with baseline spectacle wearing. The wearing of SCL leads to a small but statistically significant deterioration in visual function compared with both RGPL and spectacle wearing at baseline, although mean effect sizes were not clinically relevant.
