Argon Laser

When the temperature of the target tissue exceeds 65ºC, denaturation of its proteins occurs, resulting in what is called Coagulative Necrosis.

The effectiveness of Photocoagulation depends on how the beam of light penetrates the ocular surface and how it is absorbed by target tissue – light is absorbed primarily in ocular tissues containing melanin, xantholytic pigment and hemoglobin. The area of ​​effective photocoagulation (diameter and depth) is also related to the intensity, duration and size of the “spot” used.

The treatment of Photocoagulation is performed with topical anesthesia using a special contact lens suitable for the type of treatment and area of ​​the eye to be treated.

Argon Laser treatment is mainly used in the following medical conditions:

Used in Iridectomies, Iridoplasties and Trabeculoplasties.

Vascular Retinal Diseases
Mainly in Diabetic Retinopathy (where photocoagulation is of fundamental importance to prevent disease progression and blindness), but also in the processes of Venous Thrombosis, Macro aneurysms, Retinal Vasculitis situations, and in all clinical situations that may give rise to Retinal Ischemia that is always likely to complicate with the formation of neo-vessels which may give result in serious intraocular complications.

Vitreous hemorrhages and complicated retinal detachments

Degenerative Diseases of the Peripheral Retina
Retinal holes or tears that, if untreated, may result Retinal Detachment. Argon Laser is of fundamental importance in the prophylaxis / prevention of this situation.

Choroid Diseases
Tumors, Hemangiomas and Neovascular membranes.

COVID – 19


Em conjunto com todos os Portugueses, estamos comprometidos em vencer o surto de coronavírus (COVID-19), sendo a prevenção e a segurança, a nossa parte nesta missão.

Por isso, e seguindo as determinações dos peritos e das entidades governamentais, vamos reduzir ao mínimo a circulação de doentes nas instalações do IMO.

O seguimento dos nossos doentes com patologia urgente será garantido, mas para bem de todos, teremos de o fazer de forma diferente.

Assim, a partir de 16/03/2020, apenas atenderemos casos urgentes e sempre com atendimento médico telefónico prévio.
