Ophthalmology (ˌɒfθælˈmɒlədʒi ) is a surgical subspecialty within medicine that deals with the diagnosis and treatment of eye disorders.
An ophthalmologist is a physician who undergoes subspecialty training in medical and surgical eye care. Following a medical degree, a doctor specialising in ophthalmology must pursue additional postgraduate residency training specific to that field. This may include a one-year integrated internship that involves more general medical training in other fields such as internal medicine or general surgery. Following residency, additional specialty training (or fellowship) may be sought in a particular aspect of eye pathology.
Ophthalmologists prescribe medications to treat ailments, such as eye diseases, implement laser therapy, and perform surgery when needed. Ophthalmologists provide both primary and specialty eye care - medical and surgical. Most ophthalmologists participate in academic research on eye diseases at some point in their training and many include research as part of their career.
Ophthalmology has always been at the forefront of medical research with a long history of advancement and innovation in eye care.
Ophthalmology/Ophthalmologist is in the same field to, but different from Optometry/Optometrists.
A brief list of some of the most common diseases treated by ophthalmologists:
Cataract
Excessive tearing (tear duct obstruction)
Proptosis (bulged eyes)
Thyroid eye disease
Eye tumors
Ptosis
Diabetic retinopathy
Dry eye syndrome
Glaucoma
Macular degeneration
Retinal detachment
Endophthalmitis
Refractive errors
Strabismus (misalignment or deviation of eyes)
Uveitis
Ocular trauma
Ruptured globe injury
Orbital fracture
The most valued pharmaceutical companies worldwide whose leading products are in Ophthalmology are Regeneron (United States) for AMD treatment and Bausch Health (Canada) for Front of eye.

Optometry is a specialized health care profession that involves examining the eyes and related structures for defects or abnormalities. Optometrists are health care professionals who typically provide comprehensive primary eye care. In the United States and Canada, optometrists are those that hold a Doctor of Optometry degree. They are trained and licensed to practice medicine for eye related conditions, in addition to providing refractive (optical) eye care.
The human eye is a sensory organ, part of the sensory nervous system, that reacts to visible light and allows humans to use visual information for various purposes including seeing things, keeping balance, and maintaining circadian rhythm. The eye can be considered as a living optical device. It is approximately spherical in shape, with its outer layers, such as the outermost, white part of the eye (the sclera) and one of its inner layers (the pigmented choroid) keeping the eye essentially light tight except on the eye's optic axis.
Glaucoma is a group of eye diseases that result in damage to the optic nerve (or retina) and cause vision loss. The most common type is open-angle (wide angle, chronic simple) glaucoma, in which the drainage angle for fluid within the eye remains open, with less common types including closed-angle (narrow angle, acute congestive) glaucoma and normal-tension glaucoma. Open-angle glaucoma develops slowly over time without pain. Peripheral vision may begin to decrease, followed by central vision, resulting in blindness if not treated.
