THE VALUE OF GOOD EYESIGHT
The retina is a very thin layer of sensory nerve tissue located inside the eye. This tissue converts light into electrical signals that are sent to the brain. It could be compared to the film of a photographic camera.
Retinal diseases are divided into two large groups: those that require medical treatment and those that require surgical treatment.
At visiõnclínic+ we offer our patients comprehensive care for retinal diseases. We use the latest technology for early diagnosis and our team of expert professionals are able to offer the best treatment for each case.

WHY CHOOSE VISIÕNCLÍNIC+ FOR RETINA TREATMENT?
At visiõnclínic+ we are leaders in the diagnosis and treatment of retinal disorders. Dr. Alfredo Adán and Anna Sala are our top specialists in the field. They will be the ones who diagnose, treat and monitor all retinal pathologies, both those that require medical and surgical treatment.
The new surgical area of visiõnclínic+ is equipped with the latest advances in both the diagnosis of retinal diseases and their treatment. If the pathology requires surgery (in the case of retinal detachment or macula involvement), at visiõnclínic+ we will offer you the most appropriate procedure to carry it out in the shortest possible time.
At visiõnclínic+ we have a team made up of ophthalmologists from Barcelona’s Hospital Clínic and barnaclínic+, specialists in all areas of ophthalmology. In addition, we work with a team of optometrists, which allows us to offer a comprehensive range of services in support of your visual health. Finally, by being part of the Hospital Clínic Group, we are in contact with professionals in those care areas that may be involved in the treatment of the retina, as well as other eye pathologies.
LEADERS IN RESEARCH
TREATMENTS BASED ON SCIENTIFIC EVIDENCE
All the treatments we offer at visiõnclínic+ and, in this case, the different surgery options to treat retinal diseases, are based on published scientific evidence. The health of our patients comes first and, for this reason and to ensure their safety, we base our care on the latest medical advances available in the literature.
MEDICAL PATHOLOGY OF THE RETINA
PATHOLOGY OF VASCULAR ORIGIN
Among retinal pathologies of vascular origin, the most frequent are diabetic retinopathy and retinal vascular occlusions, mainly those of the thrombotic type that affect the veins. In this type of pathology, the treatment usually combines laser photocoagulation and intravitreal therapies through intraocular injections. It is necessary to focus on modifiable risk factors such as: hyperglycaemia, hypercholesterolemia or arterial hypertension.
Regarding retinal pathology of degenerative origin, the most frequent are: Age-Related Macular Degeneration (AMD) and retinal dystrophy.
· AGE-RELATED MACULAR DEGENERATION (AMD)
AMD affects patients from the age of 60-65 and requires evaluation and treatment in specialised centres. We have new drugs that improve the prognosis, especially if diagnosed early.
· RETINA DYSTROPHY
Retinal dystrophies are diseases of a genetic basis with different patterns of inheritance, which produce a progressive loss of visual acuity. The most common are retinitis pigmentosa and Stargardt’s disease.
DISEASES OF UNKNOWN OR IDIOPATHIC ORIGIN
Among retinal diseases of unknown or idiopathic origin, the most common is central serous choroidopathy. This disease is located in the macula and is caused by a change in a layer of the retina called the retinal pigment epithelium (RPE). The RPE has a barrier function that, for reasons not yet fully established, loses fluid. One of the reasons could be the increase of a hormone called cortisol. The increase in cortisol, which occurs in situations such as stress, would induce an increase in permeability and a “clogging” of the retina due to the passage of fluids from the pigment epithelium. In general, the disease is self-limiting and the fluid is reabsorbed spontaneously. But when visual acuity does not recover and the fluid persists, laser treatment of the leakage points in the RPE is recommended.
DIAGNOSIS OF DISEASES OF THE RETINA
For the diagnostic study of retinal diseases and the evaluation of this type of pathology, new and increasingly precise imaging systems, such as optical coherence tomography or retinal visualisation systems, wide field panoramas are currently available.
SURGICAL PATHOLOGY OF THE RETINA
Among retinal pathologies of vascular origin, the most frequent are diabetic retinopathy and retinal vascular occlusions, mainly those of the thrombotic type that affect the veins. In this type of pathology, treatment usually combines laser photocoagulation and intravitreal therapies through intraocular injections. It is necessary to focus on modifiable risk factors such as: hyperglycaemia, hypercholesterolemia or arterial hypertension.
Retinal detachment is an eye disease that occurs due to the separation of the retina due to one or several breaks. Because of this separation, fluid accumulates between the retina and the other layers of the eyeball, thus producing the alteration of the cells responsible for vision at this level: photoreceptors. It is therefore a disease that requires surgical treatment as quickly as possible to avoid significant loss of vision. The treatment of retinal detachment is surgical. There are several techniques that will have to be assessed by the surgeon and informed to the patient depending on the specific case. The surgery is done in most cases with local anaesthesia and on an outpatient basis.
AFFECTIONS OF THE MACULA
Among the affections of the macula, the most frequent are the macular epiretinal membrane and the macular hole. The epiretinal membrane is a scar tissue that grows on the retina which, if it evolves, can cause loss of visual acuity with vision distortion. In these cases, surgery may be required to remove this thin tissue to slow the distortion and, in most cases, achieve improvement. Most macular holes require gas injection surgery to achieve hole closure. These surgeries are performed with local anaesthesia on an outpatient basis.
