- Disease previously known as PCOS renamed to PMOS.
- New name reflects multi-system effects beyond ovaries.
- PMOS linked to eye issues via insulin resistance.
- Name change promotes broader research and treatment.
Millions of women have suffered from polycystic ovary syndrome for over a century, even if the disease is incorrectly termed according to the results of extensive consultations over a period of 11 years, including more than 22,000 participants who have resulted in renaming the disease to polyendocrine metabolic ovarian syndrome, which will be referred to as PMOS henceforth, appearing in The Lancet in May 2026. However, polycystic ovary syndrome is not correctly named because the so-called cysts are not pathological cysts but rather arrested follicles on an ultrasound image. But what does a name change have to do with your eyes? More than most people realise.

PMOS And Its Multi-System Effects
PMOS has now officially been classified as a disorder with multiple physiological systems at play, affecting aspects like endocrinology, metabolism, reproduction, skin, and psychology. The latter aspect is especially significant because PMOS can affect the ophthalmological aspects of health. When a disorder focuses solely on reproductive organs, aspects such as eye problems get ignored. This has been the hidden price of the previous terminology.
The ocular connection to this condition runs through two of its defining mechanisms: elevated androgens and insulin resistance.
There have been several findings of significantly higher numbers of meibomian gland loss in females who have the condition, the meibomian glands being the small glands in the eyelids that secrete oils and prevent evaporation of tears. Sub-clinical inflammation, hyperandrogenism, and insulin resistance may be the reasons behind this phenomenon, with the latter often under-diagnosed clinically.

The Eye Risks Linked To Insulin Resistance
Insulin resistance is another dimension of potential harm. Elevated glucose levels may cause damage to the blood vessels of the eyes, resulting in complications such as diabetic retinopathy, with inflammation being a possible contributing factor in developing uveitis, which refers to inflammation of the middle layer of the eye. There is also new scientific evidence related to the retina. While some studies point out the possibility of the disorder having a protective effect on the retinal nerve fibre layer, there have been findings suggesting that disorders related to metabolism, including insulin resistance and obesity, might make the eye more susceptible to macular problems.
That is the very reason why renaming is crucial. Terminology used within medicine determines diagnosis, therapy, and research. By being centered on ovarian cysts, the name had kept doctors and patients from considering the endocrine and metabolic aspects of the disorder, as well as from taking into account the possibility of any effects on other parts of the body, such as the eyes. With the name highlighting the endocrine and metabolic nature of PMOS, there is room for the participation of ophthalmologists in managing this disorder.
