Argon laser photocoagulation in the treatment of central serous retinopathy.
In a prospective randomised trial of argon laser photocoagulation in the management of central serous retinopathy it was confirmed that this treatment hastens resolution of the serous detachment. No evidence was found to suggest that treatment influences the final visual outcome in eyes with initial visual acuity of 6/12 or better.
متن کاملRecovery of the electroretinogram in rabbits after argon laser photocoagulation.
Argon laser is widely used to coagulate the diabetic retina in order to inhibit the proliferative stage of diabetic retinopathy. Ten pigmented rabbits underwent retinal photocoagulation with argon laser. Retinal function was assessed electroretinographically before treatment and at different time intervals after treatment. The ERG responses measured 4-7 days after treatment were reduced in ampl...
متن کاملCytochemical studies on pathological Müller cells after argon laser photocoagulation.
The cytochemical localization of G6Pase activity, which is specific to the endoplasmic reticulum (ER) of Müller cells, was studied after argon laser photocoagulation in the guinea pig retina. After argon laser radiation, Müller cells exhibited enlargement of the cytoplasm, an increase of reactive ER and the nuclei, dislocation of the nuclei and diagonal stretching of the cytoplasm. However, cel...
متن کاملChoroidal microvascular repair after argon laser photocoagulation. Ultrastructural observations.
Acute laser injury to the tapetum of the feline retina produces thrombosis of the choriocapillaris. Early changes are characterized by the appearance of platelet-fibrin thrombi within capillary loops and disruption of endothelial integrity. By 4 days, thrombi have disappeared, and the endothelium shows regenerative changes. No endothelial cell mitotic activity is seen. The endothelial cytoplasm...
متن کاملRetinal branch vein occlusion: a study of argon laser photocoagulation in the treatment of macular oedema.
A control trial is reported which demonstrates that treatment with argon laser photocoagulation to certain patients with macular oedema following a branch vein occlusion does not alter significantly their visual prognosis. It confirms that patients with an intact perifoveal capillary arcade have a better prognosis than those with a broken arcade.
