Study summary

This study is being done to discover if there is a link between estrogen exposure and the severity of Fuchs Endothelial Corneal Disease. We are trying to understand if the decrease in estrogen levels in post-menopausal women may be a reason why FECD is seen more often in women than men.

Study population

Individuals with mild or severe Fuchs Dystrophy

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Individuals with FECD grade 1-2/7 (mild) or 5-6/7 (severe) in one or both eyes
  2. Age ≥ 55
  3. Phakic and pseudophakic individuals will be included. Pseudophakic patients must have evidence of routine cataract surgery (posterior chamber intraocular lens in-the-bag without clinical evidence of damage to any intraocular structures).

Exclusion criteria

Exclusion Criteria:

  1. Females are excluded if not .
  2. Pseudophakic patients with a history of complex cataract surgery or other intraocular surgery (e.g. have an anterior chamber lens, sulcus lens, or poorly positioned posterior chamber lens, aphakia, iris damage, glaucoma surgery) will be excluded due to risk of iatrogenic damage to the corneal endothelium.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
