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.

retinal dialysis is a specific type of retinal tear located at the far edge of the retina. It refers to a separation of the retina at the **ora serrata**, where the retina meets the ciliary body. It is most commonly discussed in the context of eye trauma and retinal detachment risk. Ophthalmologists use the term to describe a characteristic peripheral retinal break that may need treatment or monitoring.

lattice degeneration is a thinning and structural change of the peripheral retina. It looks like elongated patches or “lattice-like” streaks during a dilated eye exam. It is commonly discussed in retinal care because it can be associated with retinal holes or tears. Clinicians use the term to document a retinal finding and to guide monitoring and risk assessment.

A giant retinal tear is a large break in the retina, the light-sensing tissue lining the back of the eye. It involves a full-thickness tear that extends across a substantial arc of the retinal circumference. The term is most commonly used in emergency eye care and retinal surgery when evaluating or repairing retinal detachment.

A horseshoe tear is a specific type of break in the retina, the light-sensing tissue lining the back of the eye. It is shaped like a “U” or horseshoe because a flap of retina is pulled forward by traction from the vitreous (the eye’s internal gel). The term is commonly used in ophthalmology and optometry to describe a retinal tear pattern that can be clinically significant. It often comes up when evaluating flashes, floaters, or risk of retinal detachment.

An atrophic hole is a small, full-thickness opening in the retina caused by thinning and tissue loss. It is most often found in the peripheral (outer) retina during a dilated eye exam. Clinicians commonly use the term when documenting retinal findings related to retinal degeneration. It matters because some retinal holes can be associated with fluid leakage under the retina.

A retinal break is an opening through the retina, the thin light-sensing tissue lining the back of the eye. It is a clinical finding ophthalmologists and optometrists look for during a dilated eye exam. Retinal breaks include tears and holes, and some types can raise concern for retinal detachment. The term is commonly used in emergency eye care, routine retina evaluations, and surgical planning.

A retinal tear is a break in the retina, the light-sensing tissue lining the back of the eye. It most often happens when the vitreous gel pulls on the retina and creates a split or flap. The term is commonly used in eye exams, emergency eye care, and retina clinics. It matters because a tear can allow fluid to get under the retina and lead to retinal detachment.

exudative retinal detachment is a type of retinal detachment caused by fluid collecting under the retina. It happens without a retinal tear or hole. It is most commonly discussed in eye clinics and hospitals when evaluating sudden or progressive vision changes. It is also called a *serous* retinal detachment in many clinical settings.

tractional retinal detachment is a type of retinal detachment caused by pulling forces on the retina. It happens when scar-like tissue or abnormal membranes contract and lift the retina away from the back of the eye. It is most commonly discussed in retinal disease care, especially in advanced diabetic eye disease. Clinicians use the term to describe a specific mechanism of detachment that affects evaluation and treatment planning.

rhegmatogenous retinal detachment is a type of retinal detachment caused by a break in the retina. It happens when fluid passes through a retinal tear or hole and separates the retina from the tissue beneath it. It is commonly used as a diagnosis in emergency eye care and retina clinics. This article is informational and explains terms and typical clinical approaches in general.

retinal detachment is a condition where the retina separates from the tissue layers that normally support it. The retina is the light-sensing layer at the back of the eye that helps create vision. This term is commonly used in eye clinics and emergency settings to describe a time-sensitive cause of vision symptoms. It is discussed in both diagnosis (what is happening) and treatment planning (how to repair or manage it).

pigment epithelial detachment (PED) is a finding where the retinal pigment epithelium lifts up from the layer beneath it in the back of the eye. It is most often discussed in retina clinics because it can appear in conditions such as age-related macular degeneration and central serous chorioretinopathy. Clinicians commonly identify pigment epithelial detachment (PED) on retinal imaging, especially optical coherence tomography (OCT).

intraretinal fluid means fluid that has collected within the layers of the retina. It is most often discussed as an imaging finding, especially on optical coherence tomography (OCT). Clinicians look for intraretinal fluid because it can signal retinal swelling (edema) and active disease. It is commonly used to help diagnose, monitor, and guide care in macular conditions.

subretinal fluid is fluid that collects under the light-sensing retina. It sits between the neurosensory retina and a support layer called the retinal pigment epithelium (RPE). It is commonly discussed as a clinical finding on retinal imaging, especially optical coherence tomography (OCT). It matters because it can blur or distort vision and can signal several retinal diseases.
