Scientific Sessions to be Discussed
The visual
system is a model for higher brain
function studies. The main two aspects
of visual neuroscience are, the function of brain mechanisms that encoding
information about the form, color, motion, and depth of visual objects and
scenes and other that decoding this information to generate perceptual
experience and visually-guided action.

Ocular microbiology details advancements in molecular biology and pave
way for better understanding of ocular diseases. The field of infectious diseases are rapid,
thus many opportunistic pathogenic agents are increasingly found in ocular
infections due to widespread use of topical and systemic immunosuppressive
agent. These opportunistic pathogens cause ocular infections due to continuous
use of contact lens. The dreadful
cataract extraction and lens implantation often are mainly caused by
these opportunistic pathogens.The acute infections of the external eye are
caused by a vivid range of microbiological pathogens .

A visual prosthesis
has the significance of restoring
of vision .It is achieved by stimulation of nerve fibers . All retinal prostheses under development are
intended to deliver electrical pulses on to the retina. The retinal prosthesis will capture visual
images using micro electronic prosthesis
and turn light energy into electrical pulses, and pass electrical pulses
to the retina thus enabling the blind to
have vision. Visual prostheses could interface with the visual pathway at
multiple locations.

Eradicating ocular melanoma is done by radiation and
surgerical method. The common
radiation therapy used to
treat ocular melanoma is called plaque
radiation therapy. A disk attached with
radioactive seeds, called plaque is placed directly on the wall of the eye lying next to the tumor. Treatment options
will vary based on the location and size of the melanoma and health. Melanoma on the eyesurface is treated with
chemotherapy eye drops, freezing treatment, and radiation.

The cornea is the protective outer layer of the eye.
Corneal disease terms the condition that affect cornea of eye. These include infections, tissue breakdown,
and other disorders transfered from parents. Eye diseases and injuries cause corneal damage. Cornea is cone shaped rather than domeshaped in the Keratoconus and in Fuchs’
dystrophy the cells in the inner layer of the cornea are malfunctioning.

Glaucoma is a disease which damages the eye’s optic
nerve. It happens when fluid builds up in the front part of the eye. That extra fluid present increases the
pressure in the eye, damaging the optic nerve. In recent years there has been new surgical advances in glaucoma
surgery. The XEN Gel Stent , a hybrid
between traditional glaucoma surgery and
invasive glaucoma surgery.

Orthokeratology is shortened as "ortho-k" and
called corneal reshaping (CR) or corneal refractive therapy. Orthokeratology refers to usage of gas permeable contact
lenses that reshape the cornea and reduces refractive errors such as myopia,
hyperopia and astigmatism. New ortho-k
lens designs are available for farsightedness and presbyopia. Research also stated that orthokeratology lens designs
slowers the progression of myopia.

The unique products
have to be different from what the big-box stores offer. Price doesn't be an issue with unique
products, they gain the value back
because they are harder to find .
The successful Optometrists are those who surround themselves with an Accountant, Lawyer and Banker. These industry experts help when making key
decisions, like buying an existing practice or financing a new, practice
valuation, loan structure and industry trends that might affect future
decisions, so the solid planning is
important . Opening a new Optometry practice is a risky but a
rewarding venture. The market

The damage to
photoreceptor cells of the retina is known as the retinal degeneration. The
photoreceptor cells are the light sensing cells in the retina, a delicate nerve
layer that lines behind the eye. The
photoreceptor cells absorb the light
and initiate a continuous
electrical impulses that are sent through the retina via optic nerve to the
brain and create an image. When the
photoreceptor cells malfunctions due to the degenerative disease, the image
received is distorted or completely
unseen. The common retinal degenerative diseases are Age-related Macular
Degeneration (AMD) and Retinitis Pigmentosa (RP). The artificial retina is the
current solution to this problem.

Ocular surgery
always progresses along the advancement of science advances. New emerging technologies in laser enhance
the surgeries. When the natural lens of your eye becomes cloudy due to age its known as cataract. It can be replaced with an artificial lens implant. An ophthalmologist prefers surgical
instruments and ultrasound power to
replace the eye's cloudy lens. The surgeons are dealing in such tiny spaces in the eye, they depend on lasers not blades, for improved precision, though lasers have
been used only for other eye surgeries, such as vision correction (LASIK)
surgery.

Ocular
drug delivery was a milestone to pharmacologists due to eye's unique anatomy and physiology. The clinical
demand arises for the delivery of therapeutic molecules in the anterior and
posterior parts of the eye. Conventional eye drops are used for the treatment
of ocular low corneal penetration but has poor ocular bioavailability (∼5%). Hence biopolymers are preferred for the composite
materials that enhances the precorneal
retention time, drug delivery control and induces the corneal absorption of drugs.

A visual testing of a patient's iris is to make a diagnosis. Iris abnormalities caused from trauma, infection, neoplasm and genetic
reasons. The iris structure is composed of connective tissue
and blood vessels that lies anterior to lens. The central opening of the iris
denotes the pupil. The color of iris is
determined by pigmented cells lies in
the stroma. Pigment accumulate in these cells during the first year of life,
and the color of iris often changes
during times. The posterior layer of
iris is deeply pigmented. It also extends slightly onto the anterior
surface of the pupil.

The vision
disorders are refractive errors, more commonly referred as nearsightedness,
farsightedness, astigmatism and presbyopia.
When the shape of eye prevents
light from focusing directly on to retina leads to refractive errors . The
eyeball length ,corneal shape change ,
or lens aging causes refractive errors. Anisocoria is characterized by an unequal eyes' pupil size. Astigmatism is a vision
condition that causes blurred vision occuring
when the cornea is irregularly
shaped and sometimes because of the curvature of the eye lens inside.

Several diseases affect the eye, either directly or
indirectly . These conditions require
urgent professional care to preserve the vision. The common types of the eye
diseases are pink eyes,styes and chalazia etc. Pink eye is an
infection of the transparent membrane that lines the eyelid and covers
the white region of the eyeball. It iscommonly caused by the bacterial and
viral infection, or an allergic reaction and it iscontagious.Styes and Chalazia
,two common conditions that affect the eyelids. A chalazion causes blockage
of the small oil producing glands
(meibomian glands) that found in the upper and lower eyelids. Styes are
infections or abscesses of the eyelid gland near an eyelash root or follicle.

Children experience more changes in bodies and vision
while growing. Thus it is
recommended for testing the
baby's eyes between ages 6 months to one year and especially if
the child was born prematurely or it has a lazy eye or crossed eyes or there is
a family history of eye disease. Once children reach three age, eye
examinations should be conducted regularly. Professional
eye care is important part in the child's annual health care routine. During first 12 years of life, 80 percent learning is
through vision hence Vision problems detected early are more helpful to treat,
and may avoid the need for glasses or a strong vision prescription.

Diagnostic imaging techniques gains tremendous importance in the
examining ocular and orbital disease.
The diagnostic imaging, with special focus directed toward the advanced modalities
are important in evaluation of the traumatized eye. Advances made in diagnostic and imaging
techniques within the years have
revolutionized the field, and helps in management of many ophthalmic
diseases. The basic tools of refractive
surgery are Wavefront and Optical Coherence Tomography (OCT).

In the visual
cognition, high-level vision, mid-level vision and top-down processing refers to decision-based scene analyses and
combines prior knowledge with retinal input to create representations. This is the method by which the brain gets visual
information and thus it process
information and its ability to recognize one's visual misconceptions and fufils
the efforts to merge the knowledge gaps.

Optic neuropathy generally describes optic nerve
abnormalities or damage, also including the causes as blocked blood flow and
exposure to toxic. The symptoms for optic
neuritis can include blurring and blind spots and even distorted vision,
reduced color vision and pain on the eye movements. These types of symptoms may lead to vision
loss due to optic neuritis. Optic
neuritis occurs in adults younger than
45 and affects more on women . The common condition in people having
multiple sclerosis (MS), where the nerve coverings are destroyed by the immune
system.
