neovascularization elsewhere (NVE) means abnormal new blood vessels growing on the retina away from the optic disc. It is a clinical term used in retinal exams and imaging reports. It most commonly comes up when grading ischemic retinal diseases such as diabetic retinopathy. It matters because these new vessels are fragile and can bleed or scar.
neovascularization of disc (NVD) means abnormal new blood vessels growing on or very near the optic disc (the “nerve head”) inside the eye. It is most commonly discussed as a clinical sign of retinal ischemia, meaning the retina is not getting enough oxygen. Clinicians use the term when examining the back of the eye (fundus) in conditions such as proliferative diabetic retinopathy and some retinal vein occlusions. It is a finding—not a standalone disease—and it helps guide further evaluation and management discussions.
retinal ischemia means reduced blood flow and oxygen delivery to the retina. The retina is the light-sensing tissue lining the back of the eye that supports vision. This term is commonly used in eye exams, imaging reports, and discussions of retinal vascular disease.
diabetic macular edema (DME) is swelling in the macula, the central part of the retina responsible for sharp, detailed vision. It happens when diabetes-related damage causes fluid to leak from retinal blood vessels into macular tissue. It is a common cause of vision changes in people with diabetic retinopathy. The term is used in eye clinics to describe a specific, treatable pattern of retinal thickening and fluid.
proliferative diabetic retinopathy is an advanced stage of diabetic eye disease that affects the retina. It happens when abnormal new blood vessels grow on the retina or optic nerve due to diabetes-related poor blood flow. It is commonly used as a clinical diagnosis in eye exams, retina clinics, and diabetes-related vision screening.
PDR stands for **proliferative diabetic retinopathy**. It is an advanced stage of diabetic eye disease where **abnormal new blood vessels** grow in the retina. PDR is commonly identified during a **dilated eye exam** in ophthalmology and optometry clinics. It matters because these fragile vessels can bleed or scar, which can threaten vision.
nonproliferative diabetic retinopathy is an early-to-intermediate stage of diabetic eye disease that affects the retina. It means diabetes-related damage is present, but new abnormal blood vessels have not started growing. It is commonly used as a clinical diagnosis and staging term in eye exams, retinal imaging reports, and diabetes-related screening programs. It helps clinicians describe severity, guide monitoring, and plan treatment if complications develop.
NPDR stands for nonproliferative diabetic retinopathy. It is an early-to-intermediate stage of diabetic eye disease that affects the retina. NPDR is commonly used by eye clinicians to describe what they see on a dilated retinal exam and imaging. It helps communicate severity and guides monitoring and treatment planning.
diabetic retinopathy is an eye disease caused by diabetes affecting the retina’s blood vessels. In plain terms, it is diabetes-related damage to the light-sensing tissue at the back of the eye. It is commonly discussed in diabetes care, eye clinics, and screening programs focused on preventing vision loss. Clinicians use the term to describe both early, subtle retinal changes and advanced disease with complications.
myopic CNV is short for **myopic choroidal neovascularization**. It describes **abnormal new blood vessel growth** beneath the retina in people with **high myopia (strong nearsightedness)**. It can cause **sudden central vision changes**, such as distortion or a dark spot. The term is commonly used in **retina clinics**, imaging reports (like OCT), and ophthalmology/optometry education.
macular telangiectasia is a retinal condition involving abnormal, dilated small blood vessels near the macula. The macula is the central part of the retina responsible for sharp, detailed vision. The term is most commonly used in eye clinics, imaging reports, and research to describe a specific pattern of macular vascular change. It is typically discussed in the context of diagnosing unexplained central vision symptoms and planning monitoring or treatment.
central serous chorioretinopathy (CSC) is a retinal condition in which fluid collects under the macula. The macula is the central part of the retina responsible for sharp, detailed vision. CSC is commonly discussed in eye clinics as a cause of sudden or gradual central vision distortion. It is also a frequent topic in retinal imaging (such as OCT) and clinical decision-making.
polypoidal choroidal vasculopathy (PCV) is a retinal condition involving abnormal blood vessels beneath the retina. It can cause fluid leakage or bleeding that may blur or distort central vision. It is most commonly discussed in the context of macular disease and can resemble “wet” age-related macular degeneration (AMD). In eye clinics, it is identified with specialized retinal imaging and managed with medical and/or laser-based therapies.
choroidal neovascularization (CNV) is the growth of abnormal new blood vessels beneath the retina. These vessels come from the choroid, a vascular layer that normally nourishes the outer retina. CNV is commonly discussed in retinal disease care, especially macular conditions that affect central vision. It is used as a diagnosis and as a clinical concept to guide imaging, monitoring, and treatment planning.
geographic atrophy is an advanced form of “dry” age-related macular degeneration (AMD). It describes areas of permanent loss of retinal pigment epithelium (RPE) and overlying light-sensing retina. It is commonly discussed in eye clinics when explaining gradual central vision loss and reading difficulty. It is also a standard term in retinal imaging, research studies, and treatment planning.
neovascular AMD is an advanced form of age-related macular degeneration that involves abnormal blood vessel growth in the macula. It is sometimes called “wet” AMD because the new vessels can leak fluid or bleed. It is a common term used in eye clinics, imaging reports, and treatment planning discussions. It matters because it can affect central vision, which is used for reading, driving, and recognizing faces.
wet AMD is a form of age-related macular degeneration that affects the central retina (the macula). It involves abnormal blood vessels and fluid or bleeding under or within the macula. It is commonly discussed in eye clinics because it can change central vision more quickly than dry AMD. The term is used in diagnosis, treatment planning, and follow-up care for macular disease.
dry AMD is the most common form of age-related macular degeneration, an eye disease that affects central vision. It involves gradual changes in the macula, the central part of the retina used for reading and recognizing faces. It is commonly discussed in eye clinics when evaluating blurred or distorted central vision in older adults. It is also a core topic in ophthalmology and optometry education because it is a major cause of vision impairment.
age-related macular degeneration (AMD) is a common eye disease that affects the macula, the central part of the retina responsible for detailed vision. It can reduce central vision needed for reading, recognizing faces, and driving. It is most often discussed in eye clinics, vision screening, and retinal imaging reports. It is diagnosed and monitored by optometrists and ophthalmologists using eye exams and retinal scans.
proliferative vitreoretinopathy (PVR) is a scarring process that can develop on or under the retina. It most often appears as a complication of retinal detachment or retinal detachment repair. In simple terms, it is “scar tissue” that can pull the retina out of place again. The term is commonly used in retina clinics, surgical planning, and follow-up after detachment surgery.
