Comparison of the Healing Properties on Corneal Cells of Groth Factor-enriched Plasma and Autologous Serum From Aniridia Patients

This study is comparing two types of blood-derived eye drops — autologous serum (made from the patient's own blood) and growth factor-enriched plasma — for treating a serious eye surface condition called aniridia-associated keratopathy (where patients are born without an iris and develop progressive corneal damage). The study compares how well each type of eye drop helps heal corneal cells in the lab. You may be eligible if: - You have aniridia (confirmed genetically for patient group) - You weigh more than 43 kg - If you donate blood, at least 8 weeks have passed since your last blood collection - For healthy controls: you do not have aniridia, are matched by age and sex, and do not have diabetes You may NOT be eligible if: - Your blood sample is insufficient - You test positive for hepatitis B, C, or HIV - Your aniridia has not been genetically confirmed (for the patient group) Talk to your doctor to see if this trial is right for you.
