Augmented Macular Pigment-containing Nutraceutical and Central Visual Function

Augmented Macular Pigment Supplement and Pericentral Visual Function: a Randomized Controlled Trial

The purpose of this study is to prospectively analyze changes in macular pigment optical density and dermal carotenoid levels as they relate to visual field function in patients prescribed a macular pigment-containing medical food (Lumega-Z), in combination with a topical carbonic anhydrase inhibitor.

This is a prospective double-masked, randomized controlled trial which evaluates central visual field function as it relates to macular pigment optical density, contrast sensitivity, and dermal carotenoid levels in the presence of a commercial macular pigment-containing medical food (Lumega-Z). Participants will be randomized to twelve weeks of supplement + dorzolamide or twelve weeks of placebo. All packaging of supplement and dorzolamide and the placebo will be identical and distributed by a third party. Both subjects and the investigators examining patients will be masked to placebo and experimental group assignment.

Inclusion Criteria:

• Age ≥ 18 years
• Glaucoma diagnosis (H40. *) with abnormal visual field as measured by 30-2 Humphrey Perimetry (mean deviation < -2.00)
• Adequate IOP control (IOP > 7 mmHg and < 22 mmHg) by medical or surgical means measured by Goldman Applanation Tonometry for at least 3 months
• Visual field progression - decrease (more negative) in MD by 1.00 dB or more when compared to prior HVF)
• Refractive error ≤ 10 diopters and astigmatism ≤ 3 diopters
