1. What is the Retina?
The National Eye institute (NEI) is conducting and supporting research that seeks better ways to detect, theat, and prevent vision loss in people with diabetes. This research is conducted through studies in the laboratory and with patients.
For example, researchers are studying drugs that may stop the retina from sending signals to the body to grow new blood vessels. Someday, these drugs may help people control their diabetic retinopathy and reduce the need for laser surgery.
2. Macular Degeneration Age Associated
One of a leading cause for blindness the central part of the vision os affected due to bleending, neovascular, and scar tissue. The sooner the DX, the better the prognosis.
3. What is Glaucoma?
Is Defined as a optic neuropathy with or without high intra ocular pressure and optic nerve damage or field lost or scotoma apoptosis in a term where the optic nerve cells die and this happens in Glaucoma and other diseases if the patient only have high intra ocular pressure and no field lost, he is a hypertensive that have to be monotized closely by the ophthalmologist.
Cupping of the nerve, visual field lost and family history is Glaucoma. Normal intra ocular pressure is 15 to 20 mgr, but sometimes the IOP rises, damaging the optic nerve. Medications anti glaucoma are mandatory, surgery as trabeculectomy, where a bypass is performed resecting trabecular tissue and an iridectomy lowering the intra ocular pressure to normal levels.Open angle glaucoma is an ocular sindome, painless, where the patient has to be examinated with visual fields, optic nerve evaluation and intra ocular pressure in a very comprehensive way.

4. Cataract
Opacification of the crystalline lens or lack of transparency. Our lens is behind the pupil and white age. The color changes and its elasticity. That’s why the need of reading glasses, if the local changes in the lens hydratation and opacification of the fibers takes place, a cataract is formed. Then light is not able to come through the eye to excite the retina, vision is bad and poor, then a cataract extraction is mandatory. The lens it self give us due to elasticity, exelent vision at far and near vision then is a multifocal lens.
Normally speaking the cataract is a slow process and is an elective procedure to be done, but, sometimes the cataract gets intumescent and develops a phacolitic glaucoma being it self an emergency. In children are congenital cataracts or secondary to errors in the metabolism.
Before a Cataract extraction was done with a large incision 2mm phaco ultrasound fragmentation and aspiration of the nucleous and foldable intra ocular lens. The post OP is excellent same as results. In presbiopia are use intra ocular lenses with intermediate close and far vision.These cases have to be selected in order to have good results.
5. Myopia
Is a large eye, where a bad vision at far but good at near. The image is projected in front of the retina, and then concave glasses have to be worn in order to have an excellent vision. Hard contact lenses, soft or hydrophilic ones are used in order to correct the refractive error.
6. Hypermetropia
Does a smaller eye where accommodation is always taken place, then glasses have to be worn in order to see well. The rays of light come to a focus in the back of the retina that is the refractive error.
7. Astigmatism
The refraction in different meridians of the eye is not the same. This abnormality is almost due to different curvature of the corneas rarely due to the lens.
8. Fluorescein Angiography
Dye that is inyected in the vein, in order to detect abnormalities in the retinal, choroidal vascular territory diabetes mellitus with or without retinopathy, macular degeneration, ocular tumors as melonamas, vasculitis, toxoplasmosis, choroidoremia, tumors adjacent to the eye, are some of the diseases, diagnosed with procedure the angiography, has a prominent role, to DX and treat the different eye disorders in ophthalmology the pupil has to be dilatated, the dye is inyected in the vein filling the arterial, then retinal venous territory and late photos, are important to see the behavior, of the eye pathology in study.
9. Miopía Alta- falta traducir
Cirugía ocular previa llámese cataratas etc. Adelgazamiento de la retina a saber lattice o degeneración periférica en todas las causas existe un desgarro o agujero responsable de la enfermedad. Existen una gran gama de enfermedades que si existe un desgarro o agujero la retina se desprende por exudación o edema a saber eveitis tumores coroideos malignos fibroplasia retro lental, diabetes mellutus por su retinopatía, etc.
Tratamiento por deio de cirugía retinopexia o bucle escleral tratamos el agujero interno por vía escleral o externo vitrectomía posterior.
Si ya existiera hemorragia interna o en el cuero vitreo bandas vitreas que se tendrían que seccionar agujeros muy posteriores no periféricos toda la gama de enfermedades que nos presenta la retinopatía diabética o vitreo retinopatía proliferativa lo que implica recambio de ese con laser, inyección de gases tipo perflurocarbono y o inyección de aceites de silicón para mantener esa retina plegada o aplicada. Como puede observarse el desprendimiento de retina es una gran capítulo de la oftalmología y el éxito es diagnosticarlo a tiempo y darle el tratamiento adecuado lo más precozmente por lo tanto un desprendimiento de retina es un emergencia ocular que se debe de atender rápidamente por las implicaciones locales de esa retina y la visión que el paciente obtiene de ese procedimiento.
