The young, fertile female.

New research has found that testosterone may play a role in idiopathic intracranial hypertension (IIH).

Tell me more.

A research team studied 70 women with IIH and found a couple of interesting things:
1. Testosterone levels in the blood were significantly increased in women with IIH, as was the activity of enzymes involved in androgen activation.
2. Women with IIH had significantly increased levels of testosterone and an androgen precursor in the CSF compared with healthy control women.

What does that all mean?

Because current treatment options for IIH are limited, being able to potentially target androgen excess in IIH could give us another avenue for treatment. (via)


How can you tell if my keratoconus is progressing?

A study has proposed a new system for scoring progressive keratoconus.

What is the scoring system called?

The Dutch Crosslinking for Keratoconus (DUCK) score.

What does it include?

A total of five things. It includes the classic risk factors like keratometry readings and refractive error, but also incorporates visual acuity, age, and the patient’s assessment of their quality of vision.

Why do we need a new system?

Because there isn't a consensus on which parameters should be used to define progression. The progression rate of keratoconus is variable and there isn't a clear indicator on the right time to intervene.

What did the authors find?

Their retrospective study of over 500 eyes found that "the use of the DUCK score was associated with a reduction in the overall number of cases requiring cross-linking treatment without increasing the risk of progression." (via)

Space goggles may help vision loss.

This week I want to introduce Elena Biffi, an optometrist and an assistant professor at the New England College of Optometry. She is the creator of the iPhone app OCTaVia. The app contains well-annotated OCT images for multiple diseases in a fast, clear and easy manner. If you need an OCT refresher, download this free app! Great job, Elena!
