Angiography with fluorescein and indocyanine green

What is an angiography? Fluorescein angiography is a test that has been used in ophthalmology for more than 50 years. By injecting a dye into the patient’s vein, we can study the blood flow through the eye to diagnose different retinal illnesses. What types of dye are there? There are two types of dye: sodium […]

Botox (Botulinium Toxin)

THE FACTS.. Botox (botulinium toxin) relaxes muscles and is used to treat both medical conditions (such as eyelid and face spasms) and to reduce the signs of ageing (facial wrinkles). It rarely causes more than mild discomfort and can be injected without anaesthetic. Its effects generally last for around 5 months when used to treat […]


Cirugía escleral

¿Qué es la cirugía escleral? La cirugía escleral es un procedimiento quirúrgico realizado habitualmente bajo anestesia local y sedación (o general, en casos específicos), que consiste en la colocación de un anillo, habitualmente de silicona, alrededor de la capa más externa de la pared del ojo, la esclerótica. Este anillo queda suturado a la pared […]


Computerised perimetry

Measurement of visual field defects caused by diseases of the optic nerve or in the retina, caused by glaucoma or by other diseases that affect the visual pathway up to the cortex.


Corneal topography

Study of the corneal morphology for refractive surgery, contact lens adjustment and the diagnosis and follow-up of diseases such as keratoconus.


Corneal transplant

What is a corneal transplant? Corneal transplant or keratoplasty involves replacing the opaque corneal tissue when a corneal scar causes visual loss. Keratoplasty is currently highly developed and there are different techniques depending on which part of the tissue is affected. Anterior keratoplasty (where two anterior layers are replaced), endothelial keratoplasty (where only the inner […]


FDT- Matrix Perimetry

FDT double frequency technology detects glaucomatous loss in the visual field with great sensitivity. This type of visual field test is fast and very useful in those patients with difficulties to cooperate in standard visual field testing.


Flurescein angiography and indocyanine green angiography

Intravenous injection of dye (sodium fluorescein or indocyanine), in order to study the diseases of retina and choroid. This test is performed in hospital.


GDx – Nerve fibre analyser

Laser analyser which assesses the nerve fiber layer injured by glaucoma. GDX improves early diagnosis.


HRT – Confocal tomography

Confocal tridimensional laser scan of the optic nerve for the study of glaucoma. It provides a high resolution image of the elevation of optic disc and the peripapilar retina. HRT can identify normal and glaucomatous optic discs with high precision.


Intravitreal Injections

What are intravitreal injections? Intravitreal injections are used to administer drugs into the eye. The injection allows the required drugs to enter the vitreous cavity, a space situated at the back of the eye, behind the lens (as seen in the image). What are they for? Which conditions are they used to treat? Injecting drugs […]


Lancaster test

Test to evaluate the ocular motility to study some strabismus cases (squint).


Laser photocoagulation

What is laser photocoagulation? Photocoagulation is a therapeutic technique used in ophthalmology in which a scar is purposely made on the retina using a laser beam. This scar can slow down the progress of certain retinal diseases. Which diseases can it combat? What does it involve? Photocoagulation can stimulate scarring and thus improve the retina’s […]



MICRO-NEEDLING: THE FACTS Micro-needling is used to stimulate collagen production and introduce active agents, such as growth factors and hyaluronic acid and to increase absorption. It can also be used to treat hyperpigmentation, alopecia, acne, cellulitis and scarring, amongst others. Micro-needling can cause some discomfort, but it does not require anaesthesia and after 2-3 hours […]


OCT – Optical coherence tomography

System used to obtain high resolution scan images of the tissues through laser. It is specially useful for the studying in macular diseases and the optic disc.


Ocular ecography

Diagnostic test that uses ultra-sounds for the studying of retinal detachment, tumours and intraocular abnormalities that cannot be explored directly, because of opacities, such as cataracts or vitreous haemorrhages.



What is orthokeratology? Orthokeratology is a therapy in which specially adapted contact lenses are worn at night while sleeping. The lens gradually moulds the cornea so that when the patients takes it out in the morning they can see well for the rest of the day without the need for glasses or normal contact lenses. How […]


Photocoagulation with Argon Laser

Out patient laser treatment performed on the retina in cases of retinal tears and degenerations, diabetes and vascular occlusions. Also used for the treatment of open angle glaucoma (trabeculopasty).


Photodynamic therapy

Treatment of subretinal neovascularitzation. Skin and eye protection is required  for 24 hours.



What is radiotherapy? Radiotherapy consists of the use of high energy rays to destroy or reduce the tumor cells of a specifically defined area. Directing radiation towards the eye helps to weaken the tumor and to stop it from growing. What types of radiotherapy are there? The two main types of radiotherapy used in ophthalmology […]


Reconstructive Surgery

There are certain conditions which result in the eye no longer working (blindness), or causing pain and/or disfigurement because the eyeball has reduced in size, greatly altered or is absent. The eye socket can be reconstructed with various types of surgery and treatment in order to improve the patient’s cosmetic appearance. Different techniques can be […]



Photographic colour images to control the progression of fundus of the eye abnormalities.



Photographic colour images to control the progression of fundus of the eye abnormalities.


Scleral Surgery

What is scleral surgery? Scleral surgery is a surgical procedure that is normally carried out under local anaesthesia (or general anaesthesia in specific cases). It involves placing a ring, usually made of silicone, around the most external layer of the eye wall, the sclera. This ring remains sutured to the wall of the eye ball, […]


Specular microscopy and endothelial cell count

Non-contact technique to measure the density and shape of corneal endothelial cells. The endothelial cell count provides important information of the cornea. The risks and benefits of corneal surgery and general anterior segment surgery.


UBM – Ultrasonic biomicroscopy

High resolution ecography of the anterior segment for the study of the cornea, iris, eye lens, ciliary body and angle. It measures diametres, depths, and thickness of the anterior segment structures.


Ultrasonic pachymetry

It measures the thickness of the corneal structure through ultrasounds.


Visually Evoked Potentials

Test to assess the transmission of the electric potentials from the retina to the occipital lobe of the brain. The most frequent application of this study are optic nerve diseases.



What is vitrectomy? Vitrectomy is a type of eye surgery to treat problems of the retina and the vitreous. Retina is a light-sensitive tissue located in the back of the eye. Vitreous is the clear gel substance that fills the eye. Vitrectomy consists of the extraction of the vitreous humor fluid and, usually, replacing it […]


YAG Laser Treatment

Treatment of the acute angle glaucoma or prophylaxis of narrow angle (iridotomy). It is also used to perform capsulotomies after cataract surgery.
