Oculus e-Clinic

Assessment and diagnosis of ocular anormalies depends on a sound understanding of the anatomy and physiology of the visual system and its patterned deviation from the normal normal eye.look for signs and symptoms.
The ocular surface is a complex integrated system involving the cornea,conjunctiva,tear film,la final gland,basil a rim al system and the eyelids(including the meibomiam gland,and lashes).
The normal physiological function of the ocular surface depends on the interaction of these different components.working together they maintain a clear optical surface,keep the eye from drying out,and protect it from trauma and infections.changes in the structure and function of any of the ocular surface components can disrupt its delicate balance and lead to pathology.
Ocular surface have relatively limited set of symptoms and signs,and systemic approach to assess and diagnose its conditions.
A patient may present limited range of symptoms and signs.As a physician taking a detailed history is very important.Ask the patients whether they have experienced or are experiencing any of the following :
*Reduced vision:(mild blurring can occur if the tear film is disturbed ;more severe suggests cornea or other diseases involvement )
*Irritation or gritty sensation:suggests epithelial disturbances.example;allergic conjunctivitis 
*Itching :(suggests allergy)
*Pain(sharp pain suggests a corneal problem or foreign body:a duller ache may suggest uveal or scleral inflamation)
*Purulent discharge 
*watering(tearing);may be due to lacrimation(increased tear production)or Epiphora ;(decreased drainage )

See differential diagnosis  and tests on ocular surface anorlies in the next publication OCULUS II
⚠️ it is important to take note of when and how the problem developed.
⚠️Ask if there is any history of trauma
⚠️Ask if there is any history of foreign body Sensation
⚠️Ask if person wears contact lenses (how hygienic is the usage);ask how they clean and use them.

Remember to contact your eye care practitioner (opthalmologis/optometrist ) on any ocular emergency.

Embryology of the human Eye

The human eye anatomically is considered as an extension of the brain.the central nervous develop from the neural tube.A thickening appears on either sides of the neural tube in its anterior part known as OPTIC PLATE.The optic plate grows as the Foetus(baby) grows towards the surface to form the OPTIC VESICLE.the two eyes develop from these two optic vesicles.the neural ectoderm and mesoderm come together to form the optic vesicles.
As the foetus grows the optic visicles invaginates from in front and below to form the OPTIC CUP. there is a line of invagination that remains open  for sometime known as the embryonic fissure.the hyloid artery enters through the fissure to provide nutrients to the developing structures.later atrophies found dissapears.
The inner layer of the retina(main) is formed by the inner layer of the optic cup whiles the outer layer develops into the pigmented epithelium.the neural ectoderm is responsible for the secretion of the jelly-like fluid called the VITREOU…

Computer Vision Syndrome

What is computer vision syndrome? Computer vision syndrome(Digital Eye Strain) is a group of eye and vision related problems that results from prolonged computer use.
Many individuals spend prolonged time on near tasks,than at far.this puts stress on the visual system resulting in many discomforts:Near Point World.This technological generation predisposes us to spend more time on screen(laptop,smartphones,tablets) than on manual tasks,the eye always under stress and forced to adapt to tasks beyond its threshold.The average teen in the United States spends more than nine hours daily on the media for entertainment(playing computer games,Facebook,movies and office Jobs),the average 13- year old checks the social media more than hundred times daily.Analytically,people spend more time on screen than time to sleep.Prolonged  stress on the eye and other organs of the body presents clinical Alerts for multiple causes;Fatigue,asthenopia  and drowsiness.

What is DRY EYE? Dry eye is a condition in which a person does not have enough quality tears to lubricate and nourish the eye.Tears are necessary to maintain clarity of the cornea and nourishes the front surface of the eye to ensure clear vision. Any anormaly in the integrity of the eyes tear film,the production or drainage can result in dry eye.This condition is often chronic and mostly affects the older adults.
The  lower and the upper eyelids mechanically spread over the ocular surface through neuronally controlled blinking mechanism to wet the corner and other ocular surfaces and exits through the nasolacrimal drainage system.then into the nose.
Tears provide lubrication,nourish ocular surface to reduce the risk of infections,wash away foreign substances that accidentally fall on the eye,keeps ocular surface smooth to allow clear vision.
