Off the Cuff: When DREAMS Don’t Come True
As many of you may already know, the long-awaited results of the DREAM study were released at the annual ASCRS meeting in Washington D.C. For those not familiar with the study, the DRy Eye Assessment and Management Study was a large NEI/NIH-funded multicenter assessment of the effectiveness of omega-3 supplements for the management of dry eye. The study’s conclusion, that omega-3 fatty acids from fish oil supplements were no better than placebo, came as a surprise to many of us, myself included. I have tremendous respect for study’s chair Penny Asbell and the DREAM team, and congratulate them on this important accomplishment. I’ve known Penny, a highly regarded corneal specialist and professor of ophthalmology at NYC’s Mt. Sinai Hospital, for many years. As with many important studies, the devil and real value of the DREAM study will be in the details, not in the headlines it generated. In a coming Off the Cuff, we’ll explore study design and real-world relevance.

Cataract Surgery in High Hyperopia | ||||
Although cataract surgery is a well-established and standardized procedure, it can be demanding and associated with higher complication rates in high hyperopia, researchers wrote. As such, they presented clinical data for highly hyperopic patients who underwent cataract surgery over a 12-year period (2005 - 2016) and at a single center. Out of a total of 11, 434 cataract operations, 41 highly hyperopic eyes (SN60A≥ 31D) were included for analysis. Researchers compared the target spherical equivalent to the final postoperative spherical equivalent for five different formulas. They also reviewed the best-corrected distance visual acuity (BCDVA) before and after surgery and any complications. LogMAR BCDVA increased significantly from a mean of 0.5 before to 0.37 after surgery (p=0.02). The main reasons for the reduced final BCDVA were glaucoma, Fuchs’ corneal endothelial dystrophy and age-related macular degeneration. One eye suffered a radial capsule tear and received a sulcus implanted intraocular lens (IOL). There was no statistically significant difference between formulas with respect to aberration of the final spherical equivalent. Patients with high hyperopia often have ocular comorbidities. Researchers wrote that such eyes can be surgically challenging, resulting in reduced benefits from cataract surgery compared with normal eyes. |

The Effects of Repeated Ozurdex Injections on Ocular Hypertension | ||||
The purpose of this study was to correlate the degree of ocular hypertension with the number of Ozurdex injections. Intraocular pressure (IOP) fluctuations for a total of 183 injections were studied over a period of at least 12 months. The main indications for treatment were uveitis, diabetic macular edema and retinal vein occlusion.
Results of the study demonstrated that repeated Ozurdex injections did not increase the frequency of IOP spikes beyond 30mm Hg. For lower IOPs, however, a positive correlation existed. Furthermore, patients with primary open-angle glaucoma and uveitis had the highest IOP response to repeated injections. On average, patients with an IOP of ≥ 28.6mm Hg received pressure lowering medications, after which their IOP reached a stable level (16.7mm Hg) without the need for additional interventions. Investigators found that multiple Ozurdex injections did not increase the frequency of IOP spikes beyond 30mm Hg, but advised that patients with a history of primary open-angle glaucoma still must be closely monitored. |

The Use of Optical Coherence Tomography for the Detection of Early Diabetic Retinopathy | ||||
Diabetic retinopathy (DR) is one of the leading causes of vision loss globally, with a severe burden on all societies due to its high treatment and rehabilitation costs, authors wrote. They added that early diagnosis of DR might provide preventive steps (including retinal laser therapy, and tight carbohydrate, blood pressure and cholesterol control) that could in turn help to avoid progression of the pathology with the resultant vision loss.
Optical coherence tomography (OCT) enables the in vivo structural imaging of the retina, providing both qualitative (structure) and quantitative (thickness) information. In past decades, extensive OCT research has been done in the field of DR. In the current review, the authors focused on studies that aimed to detect the earliest retinal changes before DR could be diagnosed funduscopically. Authors concluded that spectral-domain OCT—the latest, widely available imaging technology—offers fast and reliable retinal imaging, which, together with recent developments in image processing and artificial intelligence, holds promise for development of a quick and efficient, state-of-the-art screening tool for DR. |

Alcon Adds Gemstone Collection to Air Optix Colors Lens Portfolio, Introduces 2-Count Packs to Invite Patients to “Play with Color” Alcon introduced its new Air Optix Colors Gemstone Collection of color contact lenses, with three new colors—Amethyst, True Sapphire and Turquoise—to enhance any eye color. Now offering a total of 12 colors, Air Optix Colors lenses appeal to a wide range of patients and offer new revenue potential for practices. At the same time, Alcon launched a two-count pack for all Air Optix Colors, enabling eye care professionals to introduce more patients to color contact lenses, with or without vision correction. This smaller-size pack gives patients the ability to try out eye color for part-time wear and evaluate multiple colors. To support practices in rolling out the collection, Alcon will provide updated social and online media assets on the Alcon Vision Care Marketing Portal. In addition, patients can virtually try on the colors before coming to the office through the Air Optix Colors Color Studio. |
