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 VITREO

World Sight Day 2019 Vision first Vision is the most dorminant of the five senses . The wealth of a healthy eye and a 20/20 visual acuity cannot be underestimated.This is why the global society is built on our ability to see. The onus lies on Myself (Dr. Joel Kyeremeh, OD) and other medical professionals to do our bit in realization of the universal eye health system in every corner of the world we find ourselves. World sight Day is an annual day of awareness to focus on preventable blindness and vision impairments . The global human population is estimated 7.3 billion people in world . The demographic and lifestyle changes in human population now as compared to eons back has predisposed humans to myriad of unavailable health problems as the age. Everyone, if they are lucky to live long enough will experience at least one eye condition in their lifetime that require appropriate care . This eye care must be administered by eye professionals whose distribution are in pausity.

Ocular Morbidity Among Selected Schools in Northern Ghana Ocular morbidity refers to any abnormality in structure or function of the human eye. As a clinical optometrist my vision is to administer comprehensive eyecare services to all irrespective of their class or location in Ghana.My survey on the need for eyecare services showed Northen Ghana( upper west,upper east and northern region) were inequitably underserved. This necessitated myself and our medical team embarking on a simple random sampled group of schools to identify morbity patterns in these schools and recommend both preventive and curative measures to curb the anormalies found. A sample sizes of the school was based on the number of first years admitted yearly and the size of the schools. All first year students admitted were screened. The team included: 2 General physicians 1 Clinical optometrist  2 medical laboratory scientists  4 Nurses 1 ENT specialist  1 Dental specialist. Cities/ schools selected

EYECARE EVERYWHERE  World Sight Day-2018 As eyecare professionals I will take this opportunity to congratulate all cadres in the eyecare team for making this vision possible. We owe it to God not men to give the best eyecare service to all men irrespective of who they are or where they live . The ancient Roman words best explains it; Oculus populis, Oculus dei. This means the eyes of men are the eyes of God. As Doctors let’s do well to serve God through men. God bless all Doctors around the world as we celebrate today the impact you are all making to make the world a better place. God bless you. I am Dr. Joel Kyeremeh,O.D Let’s join hands as we work together to achieve Millennium Development Goal 6 : universal health for all. With this the true equity in healthcare will be accomplished. This is a call to responsibility nonetheless there are still more people who still do not have access to medical care .

CORNEAL ULCER(microbial keratitis) The term keratitis / microbial keratitis are used to describe all suppurative infections of the cornea.They are characterized by the presence of white or yellowish infiltrates in the corneal storma, with or without overlaying corneal epithelial defect and it’s associated  with signs of inflammation. The cornea has certain defensive mechanisms required because of it’s constant exposure to microbes and environmental influences: Reflex eye closing  Flushing effect of tear fluid Epithelium can regenerate quickly and completely .   Any breach in any of these mechanisms may result in certain pathogens succeeding in breaching the corneal defenses through superficial injuries or minor epithelial defects, then the bradytrophic corneal tissue will respond  to the specific pathogen with a characteristic keratitis. PATHOGENESIS OF CORNEAL ULCER Corneal ulcers may be caused by : Viruses Bacteria  Acanthoamoeba Fungi Once the bradytophic co

AMBLYOPIA What is Amblyopia? How to Identify the good,the bad and the ugly signs of Amblyopia? Amblyopia is decreased vision in one or both eyes due to abnormal development of vision in infancy or childhood.  In amblyopia, there may not be an obvious problem of the eye. Vision loss occurs because nerve pathways between the brain and the eye aren't properly stimulated. The brain “learns” to see only blurry images with the amblyopic eye even when glasses are used. As a result, the brain favors one eye, usually due to poor stimulation of vision in the other eye. Another word for amblyopia is often “lazy eye.” It is the leading cause of vision loss among children. WHAT CAUSES AMBLYOPIA ? The human brain learns and adapt to visual stimulation with time. Any deprivation in this neural stimulation makes the human brain think it’s normal and hence adapt. The longer the deprivation the more difficult it gets to correct the anomaly. Normal vision develops during the firs

WATERING EYE Tears are secreted by the main and accessory lacrimal glands and pass laterally accross the ocular surface then evacuated through the canaliculus into the lacrimal sac,nasolacrimal duct and finally into the nose through the valve of Hasner. A variable amount of the tear film is lost through evaporation depending on the ambient temperature,humidity,and the rate of blinks per minute. An inefficiency in any may result in either dry eyes or watering eyes.its worth to know that any abnormal anatomy of the eye or morbidity may also result in watering eyes. General signs and symptoms note: signs are cause specific and may include multiple features of the underlining anormaly profuse tearing pain,rednes,swelling and epihora at the medial canthus in cases of dacrocystitis painless swelling in the inner canthus(mucocele)  accumulation of sulphur granules in the canthus incomplete blinks and reduced blinking rate redness of the eye congestion and redness of
