[Laser photocoagulation in idiopathic polypoidal choroidal vasculopathy. Over one year follow-up]. / Fotocoagulación láser en la vasculopatía coroidal polipoidea idiopática. Seguimiento superior a un año.

PURPOSE: Long term assessment of the evolution of Idiopathic Polypoidal Choroidal Vasculopathy (IPCV) in symptomatic patients treated by laser photocoagulation. METHODS: We carried out a retrospective study involving seven eyes in six patients with visual impairment, affected by IPCV, confirmed by indocyanine green angiography. All were treated by laser photocoagulation and monitored during a period of at least one year. The controls were evaluated during the first, third, sixth and twelfth month, in order to assess whether it was necessary to repeat the treatment. RESULTS: Of the six patients with IPCV lesions, two were men and four were women (1:2) aged between 58 and 81 years (mean = 73 years), and monitored for a time interval of 18 and 75 months (mean = 39 months). The average initial visual acuity was 0.25, and the final was 0.15. All the patients had the other eye also affected: three had a macular disciform scar, secondary to the previous haemorrhagic episodes, two had asymptomatic polyps and in one patient we defined active bilateral IPCV which was treated by laser photocoagulation. In two eyes it appeared as a macular haemorrhage, in four eyes as a serosanguinous retinal pigment epithelial (RPE) detachment and in one eye as a serous RPE detachment. Three eyes suffered a relapse which required further laser photocoagulation treatment. CONCLUSIONS: Laser photocoagulation is a palliative treatment for IPCV. Final vision achieved is poor and relapse is frequent. Other procedures should be used to treat this disease.

Uveal effusion associated with an IgM lambda subtype monoclonal gammopathy.

CASE REPORT: A 68-year-old man was referred to the hospital with progressive decreased vision in the right eye over the past year. A moderate cataract and annular choroidal thickening were found. The diagnosis of uveal effusion was confirmed by ultrasound and fluorescein and indocyanine green angiography. Laboratory studies showed an IgM lambda subtype monoclonal gammopathy of undetermined significance. The patient underwent cataract surgery, and a sub-Tenon's triamcinolone injection with a satisfactory short-term outcome. CONCLUSION: This association has not been previously reported, and it shows that IgM lambda subtype monoclonal gammopathy of undetermined significance should be added to the list of disorders associated with uveal effusion.

[Subfoveal perfluorocarbon liquid. Two new cases]. / Perfluorocarbono líquido subfoveal. Dos nuevos casos.

PURPOSE/METHODS: Subfoveal perfluorocarbon liquid (SPCL) causes vision loss and central scotoma. We present two clinical cases with this complication and we review the 5 clinical cases reported in the literature to analyse their potential prognostic factors. RESULTS/CONCLUSIONS: SPCL extraction involves an early visual acuity recovery and a central scotoma disappearance. The visual acuity recovery degree does not depend on the patient's age, the onset visual acuity or the evolution time when this last one is less than 3 months.
