Background: A treatment algorithm and screening examination have been developed to guide patient management and prospectively determine potential for highly active individuals to succeed with nonoperative care after anterior cruciate ligament rupture.
Objective: To prospectively characterize and classify the entire population of highly active individuals over a 10-year period and provide final outcomes for individuals who elected nonoperative care.
Methods: Inclusion criteria included presentation within 7 months of the index injury and an International Knee Documentation Committee level I or II activity level before injury. Concomitant injury, unresolved impairments, and a screening examination were used as criteria to guide management and classify individuals as noncopers (poor potential) or potential copers (good potential) for nonoperative care.
Results: A total of 832 highly active patients with subacute anterior cruciate ligament tears were seen over the 10-year period; 315 had concomitant injuries, 87 had unresolved impairments, and 85 did not participate in the classification algorithm. The remaining 345 patients (216 men, 129 women) participated in the screening examination a mean of 6 weeks after the index injury. There were 199 subjects classified as noncopers and 146 as potential copers. Sixty-three of 88 potential copers successfully returned to preinjury activities without surgery, with 25 of these patients not undergoing anterior cruciate ligament reconstruction at the time of follow-up.
Conclusion: The classification algorithm is an effective tool for prospectively identifying individuals early after anterior cruciate ligament injury who want to pursue nonoperative care or must delay surgical intervention and have good potential to do so.

Glaucoma Management In Children May Be Improved By Home Measurement Of Eye PressureCategory: Eye Health / Blindness | Leave a Comment |
Measurement of pressure within the eye, or intraocular pressure (IOP), is known to fluctuate throughout the day, and wide swings in patients with glaucoma are believed to be related to the progression of the disease, which can cause permanent damage to the optic nerve and vision. The clinical assessment of IOP, however, has been restricted to office visits during daytime hours…

Optogenetic Tool ElucidatedCategory: Eye Health / Blindness | Leave a Comment |
RUB researchers explain channelrhodopsin Controlling nerve cells with the aid of light: this is made possible by optogenetics. It enables, for example, the investigation of neurobiological processes with unprecedented spatial and temporal precision. The key tool of optogenetics is the light-activated protein channelrhodopsin…

CooperVision Expanding Global Recall Of Contact LensesCategory: Eye Health / Blindness | Leave a Comment |
Some lots of Avaira Sphere contact lenses have been added to CooperVision’s global recall of the Avaira brand product line. The company says the level of silicone oil residue in some Avaira Sphere lens lots did not meet its updated quality requirements. Silicon oil on the contact lens can cause discomfort, eye pain, hazy vision, and even eye injuries that require medical attention…

Cataract Surgery Could Be Revolutionized By Laser’s Precision And SimplicityCategory: Eye Health / Blindness | Leave a Comment |
Two new studies add to the growing body of evidence that a new approach to cataract surgery may be safer and more efficient than today’s standard procedure. The new approach, using a special femtosecond laser, is FDA-approved, but not yet widely available in the United States. It’s one of the hottest topics this week at the 115th Annual Meeting of the American Academy of Ophthalmology…

Optimal Algorithm Developed For Determining Focus Error In Eyes And CamerasCategory: Eye Health / Blindness | Leave a Comment |
University of Texas at Austin researchers have discovered how to extract and use information in an individual image to determine how far objects are from the focus distance, a feat only accomplished by human and animal visual systems until now. Like a camera, the human eye has an auto-focusing system, but human auto-focusing rarely makes mistakes…

Ophthalmologist Helps Develop Device For Monitoring Degenerative Eye DiseaseCategory: Eye Health / Blindness | Leave a Comment |
An ophthalmologist at UT Southwestern Medical Center has helped create a convenient device that lets patients who have a degenerative eye disease better track vision changes. With the hand-held digital device, called myVisionTrack, patients can now perform an accurate self-test in less than 90 seconds, said Dr. Yu-Guang He, associate professor of ophthalmology at UT Southwestern…
