eye casualty is a hospital-based service for urgent and emergency eye problems. It is commonly used in the UK and some other health systems as a plain-language name for an ophthalmic emergency department or acute eye clinic. The service focuses on prompt assessment, triage (prioritising by urgency), and early treatment planning. It is separate from routine eye tests and planned outpatient appointments.

emergency eye care is rapid assessment and treatment for urgent eye symptoms or injuries. It focuses on problems that may threaten vision, eye health, or comfort if delayed. It is commonly delivered in eye clinics, urgent care settings, and hospital emergency departments. It may involve diagnosis, immediate treatment, and coordination with other medical services.

ocular genetics is the study of how genes influence eye development, vision, and eye disease. It explains why some eye conditions run in families and why others occur sporadically. It is commonly used in clinics to guide genetic testing, diagnosis, and counseling for inherited eye disorders. It also supports newer treatments that target specific genetic causes.

A low vision service is a set of clinical and rehabilitation supports for people with permanent vision loss that cannot be fully corrected with standard glasses, contact lenses, medication, or surgery. It focuses on improving day-to-day visual function rather than “curing” the underlying eye disease. It is commonly offered in ophthalmology and optometry clinics, hospital eye departments, and vision rehabilitation centers. It often combines device selection with practical training for reading, mobility, and daily activities.

cataract service is an organized set of eye-care visits and procedures focused on diagnosing and managing cataracts. It commonly includes clinic evaluation, surgical planning, cataract surgery, and postoperative follow-up. It is provided in ophthalmology practices, surgical centers, and hospitals, often with optometry co-management. Its goal is to address vision problems caused by a cloudy natural lens.

refractive surgery is a group of eye procedures designed to reduce dependence on glasses or contact lenses. It works by changing how the eye bends (refracts) light so images focus more clearly on the retina. It is commonly used to correct myopia, hyperopia, and astigmatism. Some forms also aim to address presbyopia, the age-related loss of near focusing ability.

orbital surgery is surgery performed in or around the eye socket (the orbit). It is used to diagnose or treat problems involving the bones, muscles, nerves, and soft tissues that surround the eyeball. It is commonly done for trauma, tumors, inflammation, thyroid eye disease, and reconstruction. Depending on the condition, it may be performed by an ophthalmologist with orbital training, sometimes with other surgical teams.

oculoplastics is a subspecialty of ophthalmology focused on the eyelids, tear drainage system, and orbit (the bony eye socket). It includes both reconstructive and cosmetic care around the eyes and upper face. It is commonly used to improve eye comfort, protect the eye surface, and restore normal eyelid position or tear flow. It is also used to evaluate and treat lumps, swelling, and structural problems around the eye.

ocular oncology is the eye-care subspecialty focused on tumors of the eye and surrounding structures. It includes diagnosing (finding and characterizing) tumors and managing treatment and follow-up. It is commonly used in ophthalmology clinics, cancer centers, and multidisciplinary hospital teams. It also supports patients who need long-term monitoring after an eye tumor diagnosis.

A uveitis clinic is a specialized eye-care service focused on diagnosing and managing uveitis, which means inflammation inside the eye. It is commonly found within ophthalmology departments, eye hospitals, or large group practices, sometimes labeled “uveitis and ocular immunology.” A uveitis clinic often evaluates complex or recurrent “red eye,” blurry vision, floaters, or light sensitivity when inflammation is suspected. It may also coordinate care with other specialties when eye inflammation relates to systemic (whole-body) conditions.

vitreoretinal surgery is a group of eye operations that treat problems in the vitreous gel and the retina. It is commonly used to repair retinal damage, remove scar tissue, or manage bleeding inside the eye. These procedures are typically performed by a vitreoretinal surgeon (a subspecialist ophthalmologist). They are used in both urgent situations (like retinal detachment) and planned care (like macular conditions).

A retina service is a set of clinic and surgical care pathways focused on the retina, the light-sensing tissue lining the back of the eye. It is commonly provided in ophthalmology practices, hospitals, and specialty eye centers by retina-trained clinicians. A retina service may include diagnostic imaging, in-office procedures, and operating-room surgery for retinal and vitreous conditions.

A glaucoma service is a coordinated clinical service for diagnosing, monitoring, and managing glaucoma and related conditions. It is commonly delivered in eye hospitals, ophthalmology clinics, and some optometry practices with referral pathways. Its focus is protecting the optic nerve by identifying disease early and reducing risk of vision loss over time.

cornea and external disease is an ophthalmology subspecialty focused on the cornea and the eye’s outer surface. It covers conditions affecting the tear film, conjunctiva, eyelids, and front window of the eye (the cornea). It is commonly used in clinics, hospitals, and surgical centers to diagnose and manage ocular surface problems.

pediatric ophthalmology is a medical subspecialty focused on eye care for infants, children, and teenagers. It covers how vision develops and how eye diseases can affect learning, comfort, and daily function. It is commonly used in children’s hospitals, eye clinics, and multidisciplinary pediatric care settings. It often overlaps with optometry, pediatrics, genetics, neurology, and other pediatric specialties.

neuro-ophthalmology is a medical subspecialty that connects eye care and neurology. It focuses on vision problems caused by the brain, optic nerves, and the nerves that move the eyes. It is commonly used when symptoms involve both vision and the nervous system. It is often part of care in ophthalmology clinics, neurology services, and hospital settings.

vision science is the study of how vision works and how the visual system processes information. It connects eye anatomy with how the brain creates what we see. It is commonly used in eye clinics, optometry practices, and vision research labs. It also guides how tests, glasses, contact lenses, and many treatments are designed and evaluated.

vision care is the broad set of services used to assess, protect, and improve how the eyes see and how the visual system functions. It includes routine eye exams, prescriptions for glasses or contact lenses, and evaluation for eye diseases. It is commonly provided in optometry clinics, ophthalmology practices, hospitals, and community screening settings. It can be preventive, diagnostic, therapeutic, or supportive depending on the person’s needs.

eye diseases is a broad term for conditions that affect the eye, eyelids, tear system, or the visual pathway. It is commonly used in clinics, patient education, and medical training to group many different diagnoses under one topic. Some eye diseases are mild and short-lived, while others are long-term and may affect vision permanently. Understanding the category helps patients and learners navigate symptoms, testing, and treatment options.

eye surgery is a broad term for procedures that treat or diagnose conditions affecting the eye and vision. It can involve lasers, very small instruments, or implanted devices to change how the eye focuses or functions. It is commonly used to restore clarity (such as removing cataracts) or protect vision (such as treating retinal disease). It is performed by ophthalmologists, often with input from optometrists for evaluation and follow-up care.
