(Press-News.org) (Paris, France, Thursday, 18 September 2025) New research presented today at the European Academy of Dermatology and Venereology (EADV) Congress 2025 reveals that people with psoriasis face a significantly increased risk of developing age-related macular degeneration (AMD), a leading cause of vision loss.¹
Psoriasis is a chronic, systemic inflammatory disease with multiple comorbidities, including cardiovascular disease and diabetes.2 This study is among the largest to date investigating whether psoriasis also predisposes individuals to AMD, an eye disease affecting millions worldwide.3
Dr. Alison Treichel and her team conducted a 15-year retrospective cohort study using data from the US TriNetX collaborative network. The study included 22,901 patients over the age of 55 with psoriasis and compared their outcomes with three propensity-matched control groups: individuals with melanocytic nevi (MN) to represent other dermatology patients; patients diagnosed with major depressive disorder (MDD) to account for chronic disease and healthcare use; and patients who had undergone an ophthalmologic exam to ensure comparable opportunities for AMD diagnosis. Individuals with a prior diagnosis of AMD were excluded.
In a separate analysis, psoriasis patients treated with biologics were compared to those treated with topical corticosteroids who had not received biologics before or during the follow-up period.
Over the 10-year follow up period, people with psoriasis had a higher likelihood of developing AMD compared with patients in the MDD and MN cohorts, with a 56% and 21% increased risk, respectively. Looking at the two main forms of AMD – exudative (wet) and non-exudative (dry) – psoriasis was associated with a 40% and 13% higher risk, respectively, compared with the MDD cohort.
“Psoriasis is a systemic inflammatory disease in which lipid dysregulation contributes to cardiovascular disease,” explained Dr. Treichel. ““Because abnormal lipid deposition in the retina is a hallmark of age-related macular degeneration, particularly the dry form that causes progressive vision loss, it is biologically plausible that psoriasis could increase AMD risk. Our study is the first to demonstrate a novel association between psoriasis and non-exudative (dry) AMD and serves as a hypothesis generating observation for future studies”
Notably, psoriasis patients treated with biologic therapies had a 27% lower risk of developing AMD compared with biologic-naïve patients treated with topical corticosteroids only.
“Our findings support a connection between psoriasis and AMD, both exudative and non-exudative, which could be mediated by shared lipid dysregulation,” Dr. Treichel explained. “They also suggest that biologic therapies could offer protective benefits beyond skin symptoms. Further research is needed to determine whether these treatments have a true disease-modifying effect and to better understand the role of shared risk factors, including smoking, obesity, cardiovascular disease, and access to specialist care.”
Dr. Treichel emphasised that individuals with psoriasis should remain vigilant. “Patients with psoriasis should continue to follow standard eye exam guidelines and promptly report any changes in their vision to their healthcare providers. More research is needed before specific screening recommendations can be made.”
Looking ahead, the research team plans to build on these findings by analysing retinal imaging data from psoriasis patients to better characterise ocular abnormalities, define the prevalence of AMD, and evaluate the long-term effects of biologic therapy on disease progression.

Details of a new drug that aims to treat the underlying causes of obesity are being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria (15-19 September).
The treatment of obesity has been transformed in recent years by glucagon-like peptide-1 (GLP-1) receptor agonists such as semaglutide, which reduce appetite, slow the release of food from the stomach and increase feelings of fullness.
These drugs are highly effective for weight loss but many people regain weight after stopping treatment. ...
New research being presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Vienna (15-19 Sept), reveals type 2 diabetes (T2D) as a critical factor in chronic disease accumulation, particularly during the early stages.
“Concerningly, people with T2D showed faster progression to diseased states compared to those without the condition,” explained lead author Dr Jie Zhang from the Steno Diabetes Center Aarhus in Denmark. “This acceleration was observed across all age groups, with the pattern ...
Simple resistance training may help counteract age-related nerve deterioration that puts seniors at risk of injuries from falls and other accidents, according to cross-institutional research led by Syracuse University postdoctoral researcher JoCarol Shields and Department of Exercise Science Professor Jason DeFreitas.
The nerves that control our muscles naturally degrade and become slower as we age, a process referred to as denervation. This degradation is especially problematic in sedentary individuals. Counteracting this deterioration with exercise could help seniors enjoy greater independence and improve ...
A Swedish-led research team at Karolinska Institutet and Karolinska University Hospital has shown in a new randomized clinical trial that a low dose of the well-known medicine aspirin halves the risk of recurrence after surgery in patients with colon and rectal cancer with a certain type of genetic alteration in the tumor.
Every year, nearly two million people worldwide are diagnosed with colorectal cancer. Between 20 and 40 percent develop metastases, which makes the disease both more difficult to treat and more deadly.
Previous observational studies have suggested that aspirin may reduce the risk of certain cancers and possibly also the risk of recurrence after surgery ...
SAN ANTONIO — September 17, 2025 — Two instruments developed by Southwest Research Institute (SwRI) are integrated into a National Oceanic and Atmospheric Administration (NOAA) satellite set to launch into space as a rideshare on a SpaceX Falcon 9 rocket no earlier than Sept. 23, 2025.
The SwRI-built Solar Wind Plasma Sensor (SWiPS) and Space Weather Follow-On Magnetometer (SWFO-MAG) are two of four instruments integrated into NOAA’s Space Weather Follow-On Lagrange 1 (SWFO-L1) satellite. ...
All-solid-state batteries are safe, powerful ways to power EVs and electronics and store electricity from the energy grid, but the lithium used to build them is rare, expensive and can be environmentally devastating to extract.
Sodium is an inexpensive, plentiful, less-destructive alternative, but the all-solid-state batteries they create currently don’t work as well at room temperature.
“It’s not a matter of sodium versus lithium. We need both. When we think about tomorrow’s energy storage solutions, we should imagine the same gigafactory can produce products based on both lithium and sodium chemistries,” ...
Reston, VA (September 17, 2025)—A novel targeted radiation approach for a rare form of malignant tumor—the solitary fibrous tumor (SFT)—has shown significant success, achieving a near-complete response in three patients. The therapy significantly reduced cancer activity and provided symptom relief, underscoring its potential as a viable treatment option. This research was published in the September issue of The Journal of Nuclear Medicine.
SFT is a rare type of soft tissue tumor with few treatment options available. Although ...

MINNEAPOLIS — In amateur soccer players, more frequent heading, or using the head to control or pass the ball, is linked to alterations within the folds of the brain, according to a study published on September 17, 2025, in Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that soccer heading causes brain changes, it only shows an association.
“While taking part in sports has many benefits, including possibly reducing ...
Researchers have revealed a previously unknown way plants shape their growth in response to light — a breakthrough that could better equip crops to handle environmental stress.
In a first-of-its-kind finding, the team discovered how a compound that’s involved in plant metabolism can actually "reprogram” an unrelated light-sensing protein.
This unexpected interaction, which was reported in the journal Nature Communications, is an exciting step toward more fully understanding plant physiology.
“In the future, this mechanism could be exploited to fine-tune plant growth, development and stress ...
