Definition of Ophthalmology
1. Concept of OphthalmologyTo treat the globe eye or eye diseases, is to have specialized medical training (Bachelor of medicine + speciality in ophthalmology).The diseases most common tend to be conjunctivitis, keratitis, problems of lacrimal sac, strabismus, retinal, glaucoma and tumors. Numerous Dystrophic diseases and degenerative retinal and optic nerve do not have treatment if diagnosed in advanced stages of there the importance of visual prevention.
The medical act par excellence of the ophthalmologist is refraction or graduation from the view. If this is done rigorously, are diseases of anterior pole even strabismus as a response to a visual strain. Treatment of the diseases may be:
1 Pharmacology: The most frequent.
2. Optical: consistent exploration of the eye (such as optical instrument which is subjected to the laws of Physics) to determine the required graduation in sunglasses and assess if you have hyperopia, myopia. This activity is carried out also although partially by optometrists, because we have to take into account for its exact realization a number precise medical conditions.
3. Surgical: using surgery Excisional or the functional (return a function) in cases such as glaucoma (optic neuropathy associated or not associated with elevated intraocular pressure), cataract (lens opacity), Keratoconus, pterygium (invasion of the cornea by the conjunctiva), obstruction of lacrimal duct, retinal detachment etc. Refractive surgery acts exclusively on the dioptrio corneal being exclusively carried out by surgeons ophthalmologists.
Very performed cosmetic surgery today is refractive surgery, or lasik. This surgery is performed by a laser surgeon, "carving" the cornea to reduce graduation controlling (previously had been introduced graduation, corneal thickness and other data, the computer of the lasik calculates the amount of laser you need. Thanks to this surgery, the patient will decrease its dependence on the use of lenses in certain cases. It is important to know that this surgery only can be performed in patients with a right corneal thickness and the thickness depends on the number of dioptres to correct.
The need to prevent an early diagnosis and safe handling has become Ophthalmology training of high specialty or sub-specialty: Retina, Glaucoma, Cornea and refractive surgery, Oculoplastics and orbit, Low Vision, Anterior segment, strabismus, Pediatric Ophthalmology, Neurophthalmology and Neurology of the Vision each of them with a specific diagnostic and therapeutic arsenal.
2. Definition of OphthalmologyOphthalmology is the medical specialty which is responsible for the treatment of diseases of the eyes. This discipline also has application in veterinary medicine since humans and animals tend to share, in this case, similar pathological processes.
Specialists in ophthalmology are known as ophthalmologists or opticians. His work includes the diagnosis of diseases, disorders and illnesses by means of several tests.
Some eye diseases require the application of a drug treatment. This is the case of allergic, infectious and inflammatory processes. Other diseases such as cataract (total or partial opacification of the lens), myopia (refractive State of the eye where the focal point is formed prior to the retina) or glaucoma (a degenerative neuropathy of the fibers of the optic nerve due to high intraocular pressure), may require surgical interventions.
It should be noted that the exploration of the eye to determine the use of glasses or contact lenses and their corresponding graduation is the responsibility of the optometrists. Optometry is the science dedicated to the visual health care and prevention, compensation and treatment of Visual anomalies.
By measuring the refractive State of the eye, optometrists are able to detect and correct the astigmatism and strabismus and other anomalies. If the optometrist detects any illness or disease linked to the visual system, the patient must be derived to the ophthalmologist.
The perimetry or perimetry, finally, consists of the psychometric field exploration and allows to determine the bright universe that an eye can cover while it remains still.
3 Meaning of OphthalmologyOphthalmology is the medical specialty that deals with the study of the eyes, which includes treatment of typical defects and diseases that have vision, such is the case of astigmatism and strabismus.
Specifically, the ophthalmology delves into the study of the eyeball, eye muscles, the lacrimal system and eyelids.
In recent decades, and especially in the light of technological advances, the ophthalmology has made significant progress in every sense, in the cure of diseases, and also in the reduction of the most common defects. The vital importance that has been awarded to the eyes, since they are the organs that allow direct visual contact with the world that surrounds us, made constantly efforts are intended to move forward in this matter.
As well there are many diseases and defects that affect our eyes: conjunctivitis, keratitis, glaucoma, tumors, myopia, strabismus, problems in the lacrimal sac, degenerative diseases of the retina, among others.
The most common treatments to alleviate some of these conditions include: the pharmacological, who happen to be the most common; the optical, which involve the study of the eye for so determining that graduation from glasses needs the patient; and surgical, are the most common for situations such as: glaucoma, cataract, lacrimal duct obstruction, the detachment of the retina.
In the surgical field, surgery star for these times is the refractive or lasik, which consists of a laser, manipulated by the surgeon, who carved the cornea to thus achieve the patient to abandon the glasses.
By case and to avoid them it is prevention that is achieved only with a periodic visit to the corresponding medical professional is essential.
The professional dedicated to this specialty medical appoints him as ophthalmologist or optometrist and also have training in medicine should be a specialty in this topic to devote himself to the same.
