GLP-1 USE ASSOCIATED WITH PROTECTION AGAINST GLAUCOMA, CME AND ESPECIALLY AMD.

By Dr. Kevin -

 

A retrospective cohort study presented at ARVO 2026, which suggests that GLP-1 receptor agonists (such as semaglutide, tirzepatide, and liraglutide) may offer protective benefits for eye health in non-diabetic adults with a BMI of 27 or higher.

Key Findings

The study compared over 31,000 patients using these medications for weight loss against a matched group with no GLP-1 prescriptions. Over a four-year period, those on GLP-1 drugs showed a reduced risk for several major ocular conditions:

  • Significant Reductions: The most robust protection was seen against Age-Related Macular Degeneration (AMD), both dry and wet forms.

  • Glaucoma Protection: Use was associated with a strong reduction in the risk of both primary open-angle and angle-closure glaucoma.

  • Macular Health: There was a moderate decrease in the incidence of cystoid macular edema (CME).

  • Surprising Results: Contrary to some previous studies, this data showed a slight reduction in the risk of NAION (non-arteritic ischemic optic neuropathy).

Conclusion

While research has previously focused on diabetic patients, these findings suggest that the anti-inflammatory or metabolic effects of GLP-1 therapies may provide broad "protective signals" for the eyes of non-diabetics. Researchers emphasize that more longitudinal studies are needed to understand the exact biological mechanisms behind these results.

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.

CORNEA CROSS-LINKING RE-TREATMENT

By Dr. Kevin -

According to a review of a study in Cornea: “Parents of the younger patients must be clearly informed at the time of corneal cross-linking therapy (CXL) that seven to 10 years after CXL, the corneal collagen turnover may induce loss of CXL effect duration with new KC instability or progression, so the treatment could be potentially repeated if necessary in nearly 25% of the patients,”

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.
