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.

serous retinal detachment is a type of retinal detachment where fluid collects under the retina without a tear or hole. It separates the light-sensing retina from the layer beneath it (the retinal pigment epithelium). Clinicians also call it an **exudative retinal detachment**, meaning fluid “leaks” into the wrong space. The term is commonly used in retina clinics, emergency eye evaluations, and imaging reports (especially OCT).

cystoid macular edema (CME) is swelling in the macula, the central part of the retina responsible for detailed vision. It happens when fluid collects in tiny “cyst-like” spaces within the retinal layers. cystoid macular edema (CME) is commonly discussed in eye clinics because it can blur central vision and reduce contrast. It is most often identified and monitored with retinal imaging, especially optical coherence tomography (OCT).

This term describes swelling in the macula, the central part of the retina responsible for sharp, detailed vision. The swelling happens when fluid leaks from retinal blood vessels and collects within retinal tissue layers. People often notice blurred or distorted central vision, especially when reading or recognizing faces. In eye care, it is commonly discussed in diabetes, retinal vein occlusion, inflammation, and after some eye surgeries.

A macular hole is a small opening that develops in the macula, the central part of the retina responsible for detailed vision. It can cause blurred or distorted central vision while side (peripheral) vision often remains clearer. The term macular hole is commonly used in eye clinics to describe a specific retinal condition seen on examination and imaging. It is most often discussed in the context of diagnosis, monitoring, and (when needed) surgical repair.

macular pucker is a condition where a thin layer of scar-like tissue forms on the macula. The macula is the central part of the retina responsible for sharp, detailed vision. This tissue can wrinkle the retinal surface and distort vision. The term is commonly used in eye clinics and retina care to describe an epiretinal membrane.

epiretinal membrane (ERM) is a thin layer of scar-like tissue that forms on top of the macula. The macula is the central part of the retina responsible for sharp, detailed vision. When an epiretinal membrane (ERM) tightens, it can wrinkle the macula and distort vision. It is commonly discussed in retina clinics and identified during eye exams and retinal imaging.

vitreomacular traction (VMT) is a condition where the eye’s vitreous gel pulls on the central retina (the macula). It can distort the macula and affect detailed vision used for reading and recognizing faces. It is most commonly identified with an optical coherence tomography (OCT) scan in clinic. It is discussed in retina care because it can be monitored or treated depending on symptoms and retinal findings.

vitreous hemorrhage means there is blood inside the vitreous gel, the clear material that fills the back of the eye. It can cause sudden floaters, hazy vision, or a dark “curtain” effect because blood blocks light from reaching the retina. Clinicians use the term vitreous hemorrhage as a diagnosis and clinical finding that signals bleeding from structures in the back of the eye. It is commonly discussed in emergency eye evaluations, retina clinics, and after eye trauma or retinal disease.

posterior vitreous detachment (PVD) is a common age-related change in the eye where the vitreous gel separates from the retina. It often causes new floaters (moving specks or cobwebs) and flashes of light. Clinicians use the term in eye exams to describe a specific anatomic event, not an infection or a “growth.” It matters because it can look similar to, or sometimes occur with, retinal tears or retinal detachment.

goniosynechialysis is an eye procedure used to separate abnormal adhesions in the drainage angle of the eye. It is most often discussed in the context of angle-closure glaucoma and narrow-angle disease. Its goal is to reopen the natural fluid outflow pathway when it has been sealed by scar-like attachments. It is typically performed by ophthalmic surgeons, sometimes alongside cataract surgery.

trabeculotomy is a glaucoma surgery designed to improve fluid drainage from the eye. It aims to lower intraocular pressure (IOP) by opening part of the eye’s natural outflow pathway. It is commonly used in certain types of childhood glaucoma and selected adult open-angle glaucoma cases. It may be performed as a standalone procedure or alongside cataract surgery in some settings.

viscocanalostomy is a type of glaucoma surgery designed to lower eye pressure. It is usually used for open-angle forms of glaucoma when drops or laser are not enough. It works by improving the eye’s natural drainage pathways without fully entering the front chamber of the eye. It is considered a “non-penetrating” filtering surgery in many surgical classifications.
