Management of uveal tumours

ACTA OPHTHALMOLOGICA, Issue 2009
B DAMATO
Purpose The purpose of this presentation is to describe the management of uveal melanomas and the other most common uveal tumours. Methods Choroidal melanomas are treated with plaque radiotherapy if possible, with proton beam radiotherapy, stereotactic radiotherapy, trans-scleral local resection, trans-retinal endoresection, phototherapy and enucleation being reserved for patients who cannot be managed with a plaque. Increasingly, tumour biopsy is performed for histological grading of malignancy and for cytogenetic studies aimed at determining the genomic tumour type so that risk of metastatic disease can be determined. Choroidal metastases usually respond to external beam radiotherapy. Biopsy may be needed to confirm the diagnosis. Choroidal haemangiomas are treated by photodynamic therapy, with good response in most patients. Results In the large majority of patients, it is possible to conserve the eye and vision. Patients need life-long follow-up in case tumour recurrence occurs. After radiotherapy of choroidal and ciliary body melanomas some patients develop exudative and neovascular complications needing treatment. Conclusion Successful management of uveal tumours is based on a firm diagnosis, accurate staging of disease, reliable prognostication and adequate aftercare. [source]


Laser photocoagulation for choroidal neovascular membrane associated with optic disc drusen

ACTA OPHTHALMOLOGICA, Issue 2 2004
Marie N. Delyfer
Abstract. Purpose:, To report two cases of choroidal neovascular membrane associated with optic disc drusen which were successfully treated using argon laser photocoagulation. Methods:, Choroidal neovascular complications of optic disc drusen were diagnosed in two of our patients, a 36-year-old woman and a 14-year-old girl. In both cases visual acuity was 20/100 in the affected eye. Fundus examination and angiography revealed a choroidal neovascular membrane. Computer tomography identified bilateral calcified drusen of the optic discs. Photocoagulation of neovascular tissues was immediately performed. Results:, Visual acuity improved progressively, reaching 20/20 10 months after treatment in one case and 20/30 in the other. No recurrence was observed during follow-up. Conclusion:, Early diagnosis and immediate laser photocoagulation of vision-threatening choroidal neovascular membranes associated with optic disc drusen helps stop progression towards the macula and improves longterm visual acuity.

Intravitreal bevacizumab (Avastin) as a treatment of the neovascular complications of laser-induced chorioretinal anastomosis for nonischaemic central retinal vein occlusion

CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 5 2009

Abstract Purpose:, To describe the use of intravitreal bevacizumab followed by sectorial retinal photocoagulation to treat the neovascular complications of laser-induced chorioretinal anastomosis (L-CRA) for nonischaemic central retinal vein occlusion (CRVO). Methods:, Prospective interventional case series of three patients with nonischaemic CRVO who were treated with L-CRA. Patients were followed up every 2 weeks after the laser treatment. If neovascularization occurred at the site of the anastomosis, intravitreal bevacizumab (1.25 mg) was injected followed by laser photocoagulation to areas of retinal ischaemia and the area of retina anterior to the L-CRA 1 week later. Fluorescein angiography was performed to confirm the presence of neovascularization. Best-corrected visual acuity measurements were performed at every visit. Results:, Three patients (one woman, two men) with a mean age of 76.3 years developed neovascularization at the L-CRA site and underwent treatment as described with a mean follow-up time of 7 months. The neovascularization developed within 1 month after the laser anastomosis in all three cases. All patients only required one intravitreal bevacizumab injection to control the neovascularization. No complications of the intravitreal injections were noted. Conclusions:, Intravitreal bevacizumab appears to be an effective tool in the immediate control of neovascularization following L-CRA for nonischaemic CRVO. This appears to cause immediate regression of the neovascular frond and allows time for the laser, which is applied subsequently to have its effect. [source]
