Human Optokinetic Contrast Device (HOCD) to Measure Visual Function and Identify Patients With and Without Glaucoma

Stopped early · Not applicable

Conditions studied: Glaucoma

In brief

The purpose of this study is to determine if an optokinetic contrast detection device is sufficient to measure contrast sensitivity and to distinguish between patients with and without glaucoma.

• age 18 or older
• Corrected visual acuity 20/40 or better in both eyes.
• Normal Controls for Study 2
• Male or Female
• age 50 or older
• IOP (intraocular pressure) 21 or less in both eyes
• Corrected visual acuity 20/40 or better in both eyes.
• Subjects with glaucoma/ocular hypertension
• Male or Female
• Age 50 or older
• Defined as IOP> 21 without medication on two or more clinic visits in one or both eyes
• Corrected visual acuity 20/40 or better
• Normal optic nerves
• Normal automated perimetry in both eyes
• Subjects who are glaucoma/glaucoma suspects
• Male or Female
• Age 50 or over
• Increased optic nerve cupping in one or both eyes regardless of IOP
• Corrected visual acuity 20/40 or better
• Normal automated perimetry in both eyes

• History of any ocular surgery except cataract extraction or refractive surgery (LASIK, PRK, or equivalent) in either eye
• Retinal disease in either eye
• Abnormal measured automated perimetry in either eye
• Abnormal measured contrast sensitivity in either eye
