RESUMO

BACKGROUND: The manifestations of the ocular toxicity of systemic corticosteroids include posterior subcapsular cataracts and glaucoma. We describe 14 cases of serous detachment of the macula due to central serous chorioretinopathy in patients given long-term steroid therapy, which may be another potential ocular side effect of corticosteroid. CASES REPORT: The 14 (9 men and 5 women) patients were aged from 39 to 55 year old. Their systemic diseases were allergic thrombopenic purpura, optic neuritis, kidney or heart transplant, Churg and Strauss vasculitis, facial palsy, rheumatoid arthritis, systemic lupus and a kidney tumor. None of the patients had hypertension. RESULTS: Serous detachment occurred between 6 days and 10 years after the start of steroid treatment. The higher the doses, the earlier the onset of ocular disease. All patients were symptomatic, with rapid onset of blurred vision. Serous detachment was bilateral in two cases. The fluorescein angiographic finding was in most cases a single small focal hyperfluorescent leak from the retinal pigment epithelium which appeared early in the angiogram and increased in size and intensity. No diffuse degradation of the retinal pigment epithelium was seen on the fluorescein angiogram. Five patients underwent laser photocoagulation of the leaking area followed by resorption of subretinal fluid. In other patients, the symptoms disappeared as the doses of steroid were reduced. CONCLUSION: The pathogenesis of central serous chorioretinopathy remains unclear and is controversial. Corticosteroids are known to worsen the prognosis of idiopathic central serous chorioretinopathy, and serous detachment has been reported after renal transplantation. In most of these cases, chorioretinopathy was combined with diffuse leakage from the choriocapillaris. We discuss the relationship between steroid therapy and focal leakage as seen in idiopathic central serous chorioretinopathy. In conclusion, we describe 14 cases of central serous retinopathy whose clinical and fluorescein angiography were fairly typical, without obvious diffuse degradation of the retinal pigment epithelium. All these patients had been given long-term steroid therapy for various diseases.

RESUMO

AIM: To study the effect of superselective ophthalmic artery fibrinolysis as a treatment for central retinal vein occlusion (CRVO). METHODS: Retrospective, university based single centre study. The charts of 26 eyes of 26 patients treated were reviewed. Among the 26 patients, there were nine cases of combined artery and vein occlusion, three cases of combined cilioretinal artery and CRVO, and 14 cases of classic CRVO. Complete preoperative and postoperative ophthalmological examination and fluorescein angiography were performed in all cases. The therapeutic procedure comprised the infusion of urokinase through a microcatheter into the ostium of the ophthalmic artery, via a femoral artery approach. The main outcome measure was the improvement in visual acuity 48 hours after the procedure. RESULTS: Six eyes of six patients exhibited significant improvement in visual acuity immediately after the fibrinolysis procedure. Among them, four had a initial funduscopic appearance suggestive of combined occlusion of the central retinal artery (CRAO) and vein. For these patients, the visual benefit was maintained in the long term. Intravitreal haemorrhage occurred in two patients. There were no extraocular complications linked to the procedure. CONCLUSIONS: Selective ophthalmic artery infusion of urokinase was followed by improvement in VA in six out of 26 cases of CRVO. Eyes with combined CRAO and CRVO with recent visual loss appeared to be the most responsive. This treatment did not prevent the occurrence of ischaemia in the failure cases. The efficacy of in situ fibrinolysis for treatment of CRVO needs to be further evaluated in a controlled study.

RESUMO

Tuberculosis choroidal granulomas ("tubercules de Bouchut") are rare, even in patients with AIDS and active tuberculosis. The authors report the clinical and angiographical findings of three cases. Choroidal involvement was bilateral, with multiple lesions, mostly located at the posterior pole. The size of the granuloma ranged from 1/8 to 1/2 of a disc diameter. Fluorescein angiography showed early prolonged hypofluorescence and late moderate hyperfluorescence. The lesions remained stable for months despite treatment of tuberculosis, and then gradually subsided. In two cases, the choroidal granulomas were discovered before the diagnosis of disseminated tuberculosis and guided the investigations, which allowed the identification of Mycobacterium Tuberculosis bacillus in the body. In the third case, pulmonary tuberculosis had already been diagnosed. The number of tuberculosis cases is increasing together with the number of AIDS cases. This should make the observation of tuberculosis choroidal granulomas more frequent. The discovery of the typical aspects of granulomas described above during fundus examination of AIDS patients can help in diagnosing tuberculosis.
