What is Curvatural myopia?
Curvature myopia refers to a type of refractive error that develops when the cornea is curved too much. An abnormally-shaped cornea can be congenital. It can also develop later in life because the eyes continue to develop until about age 20.
What causes Buphthalmos?
Buphthalmos occurs most frequently due to primary congenital glaucoma. Other conditions which can cause raised IOP in early childhood, for example, Sturge-Weber syndrome, neurofibromatosis, aniridia, etc can also cause buphthalmos.
What are secretagogues dry eye?
Secretagogues are one of the most prominent treatment classes for dry eye. These agents are designed to encourage mucin secretion. Tear film mucins play an important role in maintaining tear film stability and moisture on the ocular surface.
What causes axial myopia?
In all species, axial myopia is predominantly caused by a significant elongation of the vitreous chamber, along with thinning of the choroid and the sclera [16, 17, 113, 124, 125, 126, 127, 128, 129, 130, 131, 132].
How do you fix Hypermetropia?
Hypermetropia can be treated with corrective contact lenses or spectacles. Alternatively, eye surgery is an option that can be very effective for suitable candidates. Traditional correction: glasses or contact lenses in the form of positive lenses.
What is congenital myopia?
By “congenital myopia” we mean any degree of myopia demonstrated at birth, or any significant degree of myopia found to be present before the age of 6 years.
Is Buphthalmos and congenital glaucoma same?
and in most cases indicates the presence of congenital (infantile) glaucoma, which is a disorder in which elevated pressures within the eye lead to structural eye damage and vision loss….

Is dry eye bad?
If left untreated, severe dry eyes may lead to eye inflammation, abrasion of the corneal surface, corneal ulcers and vision loss. Decreased quality of life. Dry eyes can make it difficult to perform everyday activities, such as reading.
What is Diquas?
Diquafosol ophthalmic solution 3 % (Diquas(®)) is a P2Y2 receptor agonist that promotes tear fluid and mucin secretion and is currently approved in Japan and South Korea for the treatment of dry eye.
Do glasses cause axial elongation?
Affixing a frosted goggle or negative lens over the eye causes excessive axial elongation of the eye, and myopia, but affixing a positive lens over the eye causes inhibition of axial elongation, and far-sightedness (hyperopia) (Figure 6).
What is axial myopia?
Axial myopia is defined as an axial length above the norm and too long for the refractive power of the whole optical system of the eye. Myopia, in particular high myopia, has become one of the major causes of visual field defects, visual impairment, and blindness.
