Also known as a punctal plug, a lacrimal plug is used to blog an opening at the end of the tear duct in order to keep the eye moist.
|
Lattice Dystrophy
Lattice dystrophy is characterized by abnormal protein fibers found throughout the stroma making the cornea cloudy and reducing vision.
|
Lens
The lens of the eye is a spherical body located behind the cornea. The lens serves to focus light onto the retina.
|
Low Vision
Low vision refers to patients that have impaired vision that cannot be fully corrected with conventional glasses or contact lenses.
|
Macula
The macula is located in the middle of the eye located in the center of the retina.
|
Macular Hole
A macular hole is a hole in the retina that develops in the foveal region of the eye.
|
Macular Pucker
A macular pucker occurs when gliotic scar tissue forms near the location of the retina responsible for central vision.
|
Map-Dot-Fingerprint Dystrophy
Map-dot-fingerprint dystrophy is the abnormal appearance of the basement membrane of the epithelium of the cornea.
|
Microvascular Cranial Nerve Palsy
Microvascular cranial nerve palsy is the interruption of blood supply to one of the cranial nerves.
|
Nearsightedness
More commonly referred to as myopia, nearsightedness is a condition where a person is able to see objects close up, but images far away appear blurry.
|
Ocular Herpes
Ocular herpes is a recurrent viral infection that causes inflammation and scarring of the cornea.
|
Ocular Hypertension
Ocular hypertension is a when there is increase intraocular pressure of the eye.
