Intravitreal Aflibercept Injections In The Treatment Of Pattern Dystrophy

Not Applicable

Withdrawn

• Conditions: Pattern Dystrophy of Macula
• Interventions: Drug: aflibercept

• Registration Number: NCT01965041
• Lead Sponsor: Manhattan Eye, Ear & Throat Hospital

Brief Summary

Adult-onset vitelliform detachments associated with pattern dystrophy is a genetic disorder that carries visual implications that most commonly affect the macula (area in the eye near the retina that is essential for sharp central vision). Adult onset vitelliform detachments have an accumulation of material on the outer retina. Over time, the abnormal accumulation of this material can damage cells that are critical for clear central vision. As a result, people with this disorder often lose their central vision, and their eyesight may become blurry or distorted.

Detailed Description

Subretinal fluid is thought to play a role in the formation of vitelliform detachments, which are associated with progressive vision loss. Fluid in the subretinal space disrupts the physical apposition between photoreceptor outer segments and retinal pigment epithelial cells, which may in turn hinder the phagocytosis of shed photoreceptor outer segments. Material derived from the unphagocytized outer segments may accumulate in the subretinal space to form vitelliform lesions, resulting in a persistent detachment. Anti-VEGF therapy in the form of intravitreal aflibercept injections may be useful in controlling or eliminating subretinal fluid, thus promoting contact between photoreceptor outer segments and the retinal pigment epithelium. Vitelliform detachments may resolve subsequent to the removal of subretinal fluid and restoration of contact-dependent mechanisms of photoreceptor outer segment recycling.

6. Participation in a study of an investigational drug or device within 30 days prior to potential enrollment into the study

7. Pregnant or breast-feeding women

8. Sexually active men* or women of childbearing potential** who are unwilling to practice adequate contraception during the study (adequate contraceptive measures include stable use of oral contraceptives or other prescription pharmaceutical contraceptives for 2 or more menstrual cycles prior to screening; intrauterine device [IUD]; bilateral tubal ligation; vasectomy; condom plus contraceptive sponge, foam, or jelly, or diaphragm plus contraceptive sponge, foam, or jelly)
