Аннотация
RATIONALE: Central retinal artery occlusion and branch retinal artery occlusion (BRAO) result in partial or complete retinal ischemia and sudden loss of vision; to date there is no effective therapy for central retinal artery occlusion and BRAO. Transluminal Nd:YAG laser embolysis (TYE) could represent a therapeutic approach for retinal vascular occlusive diseases.
PATIENT CONCERNS: We report 2 cases with BRAO, 1 with inferor-temporal and 1 with superor hemiretinal BRAO. All the patients complained of a history of sudden blurry vision and impaired visual field and had a visible embolus within the intravascular, all of them treated with TYE, the laser applications being delivered directly to the embolus.
DIAGNOSIS: The diagnosis was based on the results from color retinography, optical coherence tomography and visual field testing. Fundus fluorescein angiography clearly indicated the location of retinal artery occlusion.
INTERVENTIONS: The patients' symptoms could not be relieved after dilating the blood vessels in the eye, lowering intraocular pressure, massaging the eyeball, and inhaling oxygen. Informed consent was obtained from the patient for TYE and the patients were referred for this procedure.
OUTCOMES: Upon the successful competition of the TYE procedure the embolus was removed completely, restoring the blood flow in the intraocular vessels and improving significantly the patients' visual acuity.
LESSONS: World-wide experience with TYE is still limited, but the technique seems feasible for the treatment of RAO caused by visible emboli on the optic disc surface and the posterior pole of the fundus oculi.
