What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looked at 20 adults who have a flat spot in the center of their retina (fovea plana) but no known albinism or vision problems. Researchers used eye scans and genetic tests to see if these people carry gene changes linked to albinism. The goal was to better understand why some healthy people have this eye feature and whether it is related to albinism genes.

Lead sponsor

A research network

The lead sponsor is a research network or cooperative group.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * Patient over 18 years old; * Diagnosis of fovea plana in one or both eyes, confirmed by two ophthalmologists blinded to each other from OCT-B imaging; Exclusion Criteria: * Known Albinism * Known family history of albinism * History of eye surgery other than cataract * Alteration of macular visual function (loss of visual acuity independent of a disorder of the environments, central scotoma, metamorphopsies, etc.) * Presence of another anomaly in OCT in addition to the fovea plana (epiretinal membrane, damage to the external retina, etc.) * Syndromic fovea plana * Pregnant or breastfeeding woman
