What is myopia?
Myopia is a pathology that manifests itself with a blurred image, especially in distant vision. This occurs because, when accommodation is relaxed, parallel rays are focused in front of the retina.
What is myopia magna myopia?
High or magna myopia is myopia that exceeds 6 diopters. People who suffer from it are more likely to have diseases associated with this pathology, such as retinal detachment or myopic neovascular membranes. Therefore, it is important that they see an ophthalmologist frequently for evaluation, even if they do not show any symptoms. In the same way, other people should also have regular check-ups to prevent any ophthalmologic pathology.
What is dry eye?
Dry eye refers to a chronic lack of lubrication and moisture on the ocular surface that is usually caused by an alteration of the natural tear film, either in its quantity, quality or distribution.
The tear film is the result of the secretion of different types of glands found in the eyelids. When the contribution of each gland is not homogeneous or is not well distributed (either due to an alteration of the anterior surface of the eyeball or a decrease in blinking), areas of the ocular surface remain unprotected from the air, which causes discomfort and dryness.
Many factors are involved in dry eye syndrome, such as age, hormonal status (menopause), concomitant use of certain drugs, environmental factors (dryness, wind…), and certain diseases that must be ruled out.
What can I do if I suffer from dry eye?
There is no cure for dry eye syndrome. However, environmental measures and medical treatment can be taken that may improve it and decrease eye discomfort.
Treatment for dry eye will consist of instilling artificial tears to lubricate the ocular surface. There are different types, and it will be the specialist in Ophthalmology who will indicate the most appropriate for each patient. The most important thing is to identify the cause, whether it is a disease or a circumstance that worsens the condition, in order to avoid it as much as possible. In addition, there is the possibility of reducing tear drainage with punctal plugs, with the use of certain pharmacological supplements (which improve the proportion of substances that make up the tear film) or through the application of preparations (such as autologous serum, which, in addition to lubricating, complement the nutrition of the ocular surface with other factors).
We also have different novel therapies that can be applied on an outpatient basis, without the need for surgery, which makes it possible to increase and improve the function of the palpebral glands that contribute to the synthesis of the tear film. Thus, in a considerable proportion of cases, they reduce the need to instill artificial tears, as well as the symptomatology of ocular dryness.
