Ophthalmology and Optometry

Eye disease that could end up with permanent blindness. Hence investigation of corneal disease is carry out to mitigate the disease and methods like Contact lenses & vision correction is also use to cure the vision related problems and surgical procedure like corneal transplantation is used to transplant the cornea. The cornea and focal point of the eye are worked to concentrate light on the retina, which is the light-touchy tissue at the back of the eye. At the point when light strikes the cornea, it twists or refracts the light approaching onto the focal point. The focal point refocuses that light onto the retina, which begins the interpretation of light into vision. The retina changes over light into electrical driving forces that go through the optic nerve to the mind, which translates them as pictures.

Digital screens give off little or no harmful radiation (such as x-rays or UV rays). All levels of radiation from computer screens are below levels that can cause eye damage such as cataracts. Digital screens do exposure your eyes to blue light

In a small randomized controlled trial, production of aqueous tears and secretion of goblet cells increased following application of the Oculeve Intranasal Lacrimal Neurostimulator (Allergan).1 This handheld device works by delivering electrical stimulation to the anterior ethmoidal branch of the trigeminal nerve in the nasal cavities. It potentially offers a new mechanism for treating dry eye disease—now largely managed with artificial tears and anti-inflammatory agents.

Lazy Eye, also known as amblyopia, occurs when one eye develops poorly. Vision is weak in that eye and it moves slowly. Using corrective glasses or contact lenses may correct it. It may occur in infants, children and adults.Dry eyes is condition when there is a chronic lack of sufficient lubrication nad moisture on the surface of the eye. Consequences of dry eyes range from subtle but constant eye irritation to significant inflammation and even scarring of the front surface of the eye. symptoms of dry eye includes: Burning sensation, itchy eyes, photophobia, ache, blurred vision.

In ophthalmology, diagnosis is the major important part for deciding the treatment for the patients. Only through the proper instrumentation technique, this is achieved. The posterior part of the eye consists of vitreous humor, retina, choroid, and optic nerve. These are viewed using the proper Instruments. Mostly for retinal analysis, optical coherence tomography(OCT) is used. OCT is an imaging technique used for viewing the eye in Two- and Three- Dimensions and for capturing the micrometre resolutions. This is the most important and emerging technologies in the diagnosis because of its easy prediction, Non-invasive technique, less strain and time consumption technique. There are many instruments specially designed for the detection of the eye problems and for the rectification.

A congenital cataract is a clouding of the eye's natural lens that is present at birth.Depending on the density and location of the opacification, congenital cataracts may need to be removed by cataract surgery while the child is still an infant to enable normal vision development and prevent amblyopia and even blindness.

Congenital cataracts can occur in newborn babies for many reasons, including inherited tendencies, infection, metabolic problems, diabetes, trauma, inflammation or drug reactions

Different types of congenital cataracts:

Anterior polar cataracts

Posterior polar cataracts 

Nuclear cataracts 

Cerulean cataracts 

Vision correction surgery, also called refractive and laser eye surgery, refers to any surgical procedure used to fix vision problems. Recent years have seen huge advances in this field. Refractive and laser eye surgery allow many patients to see better than any other time in their lives.

Most types of vision correction surgery reshape your cornea, the clear front part of your eye. That lets light travel through it and focus properly on the back of your eye, or retina

LASIK -or laser in-situ keratomileusis, works for people who are nearsighted, farsighted, or have astigmatism.

Photorefractive keratectomy-is used to correct mild to moderate nearsightedness, farsightedness, or astigmatism.

Refractive lens exchange.Other names clear lens exchange (CLE)- It’s the same as cataract surgery. a small cut at the edge of your cornea. She removes your natural lens and replaces it with a plastic lens implant. The procedure can correct extreme farsightedness or nearsightedness. 

PRELEX -Short for presbyopia lens exchange, is a procedure used for presbyopia, or loss of flexibility in your eye. The doctor removes your lens and replaces it with a multifocal lens.

All glaucoma surgery procedures (whether laser or non-laser) are designed to accomplish one of two basic results: decrease the production of intraocular fluid (aqueous humor or increase the outflow (drainage) of this same fluid. Surgery isn’t usually the first step to treat glaucoma, but it may save your eyesight if other treatments don’t work. Surgery involves either laser treatment or making a cut in the eye to reduce the intraocular pressure.

In a rapidly changing world, Eye and Vision Researchers are emerging from the lab and the clinic to engage the public, patients and policymakers regarding the sight-saving work that we do and the benefits it brings to our societies. The goal is to allow Ophthalmology faculty and students to gain experience presenting research to an academic audience. It remains mission of Ophthalmic Researchers and Scholars  to carry out ground breaking research on the development, structure, and function of the visual system and uphold our position as a centre of excellence. Through this initiative research efforts have translated into clinical trials to prevent, treat and cure ocular diseases.

Ophthalmology  is a stream of medicine dealing with eye and visual system. Ophthalmology completely relates to both internal visual system and external  parts such eye ball, eye lid, eye lashes and tear formation.Treatments include right from  external eye care to using medical ,surgical and rehabilitate methods to treat various eye related problems. Many specialists such as  Ophthalmologists, Optometrists, Vision Specialists working on various aspects to eradicate blindness. To have blind free world, it is very important for the clinicians and researchers to meet and discuss about the various aspects to bring research into clinical practice. Also certain diagnosis concerns can be dealt  with finding novel solution through research. Ophthalmology conferences are being conducted to bring the researchers and clinicians together and have a beneficial discussion and make the world blind free.  

Vision Science is the technological study of vision. The visual framework is very pleasant made to transmit data of the outside world to visual assemble and subjective focuses in the intellect. The presumption of apprehension is the cerebrum's capacity to synchronize all the electrical movement it is continually accepting and producing. The necessary goal of visual neuroscience is to perceive how neural activity brings about visual acknowledgment, and furthermore hones dependent on vision.

Vision science is the scientific study of vision. Vision science surround all studies of vision, such as how human and non-human organisms process visual information, how conscious visual perception works in humans, how to exploit visual perception for productive communication, and how artificial systems can do the same tasks. Optometry is a healthcare occupation that is sovereign, educated, and regulated (licensed/registered), and optometric physician are the primary healthcare exponent of the eye and visual system who provide comprehensive eye and vision care, which includes refraction and distribute, detection/diagnosis and administration of disease in the eye, and the recuperation of conditions of the visual system.

Imperfect evaluation of patients during regime scrutiny and the failure to correlate manifestations are probably more common reasons for missed neuro-ophthalmic determine than the potential delicacy of neuro-ophthalmic symptoms. Recommendations for incorporating a more thorough, efficient eye examination in routine practice are included in the Examination efficiency.  There are several reasons of decreased vision following a neurological event (such as acquired brain injury). It is important to direct the cause of the decreased vision as it will allow the physician to discuss prediction and potential for improvement.

Our Eyes are an important part of your Health. Everyone rely on their eyes to see and make preception of the world around them. Myopia and blindness have diret effect on individual, families, and communities. These effects range from a decrease in quality of life and increased mortality to large-scale economic outcome. Primary eye care is a wide concept, circumscribe the prevention of potentially deprive of sight eye diseases through primary health care (PHC). You might think your vision is fine or that your eyes are wholesome, really be sure.

Despite advances in electroencephalogram imaging and other techniques, examination of the afferent visual sensory system is still the core of the neuro-ophthalmologic examination. A thorough refraction is an essential part of all clinical neuro ophthalmologic examinations. Conflict visual fields should be part of every afferent system examination. The relationship between the physical properties of light and perceptual and behavioural responses is known as visual psychophysics, which serves as the foundation for the clinical assessment of visual function. The resolution  of patient’s optical field improves worsens, or remains stable over time is the most difficult aspect of visual field interpretation. Many attempts have been made to investigate visual field function using evoked potentials to visual stimuli.

The Retina is a thin layer of tissue that lines the back of the eye at the back. It is found near the optic nerve. The main aim of the retina is to catch light that the lens has focused, convert the light into neural signals, and send these signals on the brain for visual identification.

Clinical Ophthalmology, is the stream which deals with  medical and ophthalmic surgical techniques, Retinal Disorders, Ocular Diseases  and laser procedures.

Your children,s vision  advancement starts before birth. From the day your child born, her eyes will help her physical, mental, and enthusiastic advancement by enabling her to learn – a tad at to start with, and in the end substantially more – about her general surroundings. The visual arrangement of a baby sets aside some opportunity to create. In the primary seven day stretch of life, babies are unable to catch much detail. Their first perspective of the world is undefined and just in shades of dark.

Pediatric Ophthalmology is a branch of ophthalmology deals with visual impairment, and vision complications in kids. Pediatric ophthalmologists doctors work along the improvement of the visual system and the different issues that disturb visual advancement in kids. Pediatric ophthalmologists have proficiency in dealing with different visual infections that influence children.

It depends on the procedure that incorporate psycho physics, eye growth, electropalatography, neuroimmunomodulation and additional ciphering modelling. Visual inquiry, spatial vision, perceptual association, semantic handling and classification, confront recognition, visual disregard, visual agnosia, perception for action, visual working memory, inhibition and psychological control, perusing, and social vision.
