Occult macular dystrophy (OMD) is a rare inherited degradation of the retina, characterized by progressive loss of function in the most sensitive part of the central retina , the location of the highest concentration of light-sensitive cells (photoreceptors) but presenting no visible abnormality.
ICD-9-CM Volume 3 is a system of procedural codes used by health insurers to classify medical procedures for billing purposes. It is a subset of the International Statistical Classification of Diseases and Related Health Problems (ICD) 9-CM.
Whilst the ICD-10-PCS codes also contains procedure codes, those are only used in the inpatient setting. [5] CPT is identified by the Centers for Medicare and Medicaid Services (CMS) as Level 1 of the Healthcare Common Procedure Coding System. Although its use has become federally regulated, the CPT's copyright has not entered the public domain ...
Scanning laser ophthalmoscopy developed as a method to view a distinct layer of the living eye at the microscopic level. The use of confocal methods to diminish extra light by focusing detected light through a small pinhole made possible the imaging of individual layers of the retina with greater distinction than ever before.

Ocular OCT retinal thickness map, right eye Time-domain OCT of the macular area of a retina at 800 nm, axial resolution 3 μm Spectral-domain OCT macula cross-section scan. Optical coherence tomography (OCT) is a technique for obtaining sub-surface images of translucent or opaque materials at a resolution equivalent to a low-power microscope.
The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan. [1] [2] Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system.
Laser photocoagulation can help prevent the deterioration of some retinal disorders and reduce the risk of future vision loss, but it cannot restore vision once it has been lost. The procedure is safe and effective for treating indicated retinal disorders, such as tears and glaucoma. It is typically an outpatient procedure lasting 15 to 20 minutes.
OCT allows professionals to see the structures in the eye, usually the thickness of the retina and optic nerve. [11] This is a noninvasive procedure where patients rest their chin and focus on a green light within the machine. [11] Eye dryness and fatigue are the limited risks associated with this scan. [11]
