Sleep Deprivation Linked to Increased ERM Risk

By Dr. Kevin -

 A South Korean study published in Retina has identified weekday sleep deprivation (defined
as averaging less than six hours of sleep per night) as a potential modifiable risk factor for developing an epiretinal membrane (ERM).

Key Findings

  • Increased Risk: Analyzing data from 15,240 participants, researchers found that sleep deprivation is associated with a 1.25-fold increase in ERM prevalence.

  • Vulnerable Groups: The association was particularly pronounced among individuals with diabetes (1.26-fold risk) and non–high-risk alcohol consumers (1.22-fold risk).

  • Predictive Power: Insufficient sleep ranked as the fourth most influential predictor (5.3%) for ERM development, following age, cataract surgery, and dyslipidemia.

Underlying Mechanisms & Study Limitations

Researchers suggest that chronic short sleep may fuel ERM formation by inducing low-grade systemic inflammation and disrupting vascular homeostasis, which compromises the eye's ability to clear inflammatory mediators at the vitreoretinal interface.

However, because the study relied on a cross-sectional design and self-reported sleep data, it could not firmly establish causality and may be subject to recall bias. Furthermore, data constraints prevented researchers from accounting for other known secondary ERM risk factors, such as uveitis and retinal tears.

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

By Dr. Kevin -

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.

Keratoconus and Inflammatory Skin Conditions

By Dr. Kevin -

 New research shows that keratoconus may be linked to certain inflammatory skin conditions, including eczema (atopic dermatitis), psoriasis, seborrheic dermatitis, contact dermatitis, and hives. People with these conditions were more likely to develop keratoconus than those without them. Rosacea did not show this connection. One possible reason is eye rubbing , which is common in itchy skin conditions and can slowly damage the cornea over time. Another reason may be inflammation in the body , which can weaken collagen—the protein that helps keep the cornea strong and stable. Because of this link, people with chronic inflammatory skin conditions may benefit from earlier and regular eye exams . Controlling inflammation and avoiding eye rubbing may help lower the risk of keratoconus or catch it earlier, when treatment is more effective.

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."
