Neuroretinal Rim Measurements Outperform RNFL Thickness for Detecting Glaucoma Progression

By Dr. Kevin -

 

This study found that event-based analysis detected glaucoma progression in a significantly higher percentage of patients and did so earlier than trend-based methods.

Monitoring structural changes (via disc photography and OCT) is helpful to catch glaucoma in its early stages, when intervention can be most effective in preventing major vision loss. A recent study, whose findings were published in Journal of Glaucoma, aimed to compare the efficacy of event-based vs. trend-based analysis in glaucoma detection.

The researchers performed both event-based and trend-based analyses and reported that the former method was significantly more effective at detecting glaucoma progression. 

Moreover, using high-density 3D OCT measurements of MDB neuroretinal rim thickness, event-based analysis detected progression in 52.4% of eyes tested, compared to only 9.7% detected by trend-based analysis using the same measurement.

The present study showed that event-based analysis using the MDB rim thickness parameter was a better test than RNFL thickness for detecting glaucoma progression over a five-year period,”

IMPLANTABLE COLLAMER LENS APPEARS BETTER THAN LASIK OR PRK FOR MODERATE TO HIGH MYOPIC PATIENTS

http://www2.cochrane.org/reviews/en/ab007679.html The results of this review suggest that the implantable lens (ICL) is are safer than excimer laser (the laser used in PRK and LASIK) surgical correction for moderate to high myopia in the range of -6.0 to -20.0 D and ICL is preferred by patients. ICL surgery resulted in better corrected visual acuity, better contrast sensitivity, and improved patient satisfaction. ICL may also be considered in cases where the patient has more moderate near-sightedness (in the range of -3.00 to -6.00). My personal experience with ICL gives me a high level of confidence in this procedure and the surgeon with whom I co-manage. All patients I have seen have been 20/20 or better. One patient was in the -6.00 range and the others in the -10 range! I see very little side effects. For more information, feel free to our office at 480-812-2211.

RINSING YOUR CONTACT LENS CASE IS NOT ENOUGH

By Dr. Kevin -

Removal of biofilm from contact lens storage cases -- Wu et al., 10.1167/iovs.10-5796 -- Investigative Ophthalmology & Visual Science It has been conventional wisdom amongst eye doctors that most infections related to contact lenses actually originate from the contact lens storage case. I usually recommend rinsing the case after use and filling with fresh solution. However, it appears that thoroughly rubbing the inside of the case with clean fingers helps remove most of the biofilm on which the bacteria grow. I also usually recommend replacing one's case on a regular basis. I am surprised how many new patients come into my office with grimy, dirty contact lens cases. According to this study: "digital rubbing and rinsing, and/or wiping the lens cases with tissue are recommended. Air-drying and recapping the lens case lids after use without any additional cleaning methods or the use of antimicrobial cases should be discouraged."
