Single spot PDT in patients with circumscribed choroidal haemangioma and near normal visual acuity
Graefe's Archive for Clinical and Experimental Ophthalmology, 2006
Background: In circumscribed choroidal hemangiomas (CCH) a long observation period and decreased visual acuity before treatment are risk factors for poor visual outcome. Therefore, we studied the use of limited, single spot photodynamic therapy (PDT) with Visudyne for the timely treatment of CCH. Methods: Six consecutive patients with CCH, and metamorphopsia but (near) normal visual acuity were treated with PDT, using a single spot covering only the most prominent part of the tumour, and a radiance exposure of 50 J/cm 2 . Start of treatment was 6 min following a 1-min infusion with Visudyne (6 mg/m 2 BSA), using a diode laser (692 nm). Results: In all patients, the metamorphopsia disappeared, the OCT images returned to a normal foveal contour, and visual acuity remained 20/20 or improved to 20/20. In five patients, the tumour became ultrasonographically undetectable; in three after one PDT session, in one patient after two and in another patient after three PDT sessions. The last patient had a residual tumour height of 1.2 mm, but no metamorphopsia, a normal foveal contour on OCT, and fluorescein angiography showed no residual leakage. Conclusion: The present series demonstrates that single spot PDT might be an effective treatment for CCH with a visual acuity ≥20/30, without serious side-effects during a follow-up of at least 18 months.
Verteporfin photodynamic therapy of six eyes with retinal capillary haemangioma
2010
Single-centre consecutive interventional case series by retrospective chart review to evaluate the efficacy of verteporfin (VisudyneÔ) photodynamic therapy (PDT) of retinal capillary haemangioma (RCH). Methods: Following an initial period of observation, six eyes of five patients with RCH (juxtapapillary 3 and extrapapillary (EP) 3) received 1-3 sessions of standard verteporfin PDT upon the development of progressive visionthreatening complications. Four of the five patients had von Hippel-Lindau (VHL) disease. Follow-up included documentation of best-corrected Snellen visual acuity (BCVA), tumour regression, and presence or absence of subretinal fluid (SRF) and ⁄ or lipid exudation as assessed by dilated fundus examination (DFE), fundus photos, and optical coherence tomography (OCT). These parameters were documented at 1 week, 1 month, and 3 months following each PDT session and up to 32 months following the first PDT. Results: All eyes showed favourable response to PDT as defined by tumour regression or stabilization as well as improvement of SRF and lipid exudation. BCVA improved or stabilized in three eyes. Three eyes required PDT retreatment for recurrent SRF. Epiretinal membrane (ERM) worsened in three eyes, requiring vitreoretinal surgery at a median of 6 months following PDT. Conclusions: PDT is a moderately effective treatment for juxtapapillary and EP RCH. In this series, PDT resulted in tumour regression or stabilization as well as in the improvement of SRF and lipid exudation in all cases. However, stabilization or improvement of visual acuity was observed in only 50 per cent of the cases. The treatment benefits may be limited by pre-existing macular changes and worsening of ERM. A larger prospective study is necessary to validate these findings.
Journal of the Chinese Medical Association, 2011
Circumscribed choroidal hemagioma (CCH) is an ocular tumor that can result in decreased vision or blindness. Numerous treatment methods have been reported without satisfying results. In recent years, photodynamic therapy (PDT) with verteporfin has been used to treat choroidal hemagioma and resolve the associated exudative retinal detachment, and the results have been inspiring. Here, we report the case of a 36-year-old man with longstanding CCH who suffered from blurred vision for 3 years. He underwent PDT with intravenous infusions of verteporfin, which was a treatment method based on a modified version of the standard macular degeneration PDT protocol, in addition to subsequent intravitreal administrations of bevacizumab as adjuvant therapy for macular edema. Twelve months after treatment, the CCH tumor remained noticeably shrunken, with the complete absorption of the subretinal fluid and the absence of macular edema. In terms of treating subretinal fluid retention, this combination treatment is a safe, effective, and long-lasting therapy for treating established CCH tumors. However, even though the patient's visual field defects improved, the patient's visual acuity remained stable at 6/60 without further improvement. Long-term CCH with prolonged macular edema might have affected the visual prognosis. Patients with CCH still require long-term follow-up examinations after receiving PDT treatments.
Retinal Cases & Brief Reports, 2017
Purpose: To report a case showing a very rare association of chorioretinal coloboma and retinal capillary hemangioma in a previously healthy patient. Methods: Observational case report. Results: A 21-year-old woman presented at our clinic for vision screening. She had a history of bilateral chorioretinal coloboma with amblyopia in her left eye. Her bestcorrected visual acuity was 20/25 in her right eye and 20/200 in her left eye. On slit-lamp examination, iris coloboma was observed in the left eye. Fundus evaluation showed inferior chorioretinal coloboma in both eyes, and an elevated, round, and orange-red retinal lesion with feeder vessels localized in the midperipheral region of the right eye. The patient was diagnosed as having solitary retinal capillary hemangioma and underwent argon laser therapy for treating the tumoral lesion. Diagnostic studies were negative for von Hippel-Lindau disease. This is the first reported case of solitary retinal capillary hemangioma associated with bilateral chorioretinal coloboma. Conclusion: Chorioretinal coloboma is a congenital defect of the eye caused by improper closure of the embryonic fissure. Retinal capillary hemangioma is a vascular retinal tumor that may occur sporadically or as part of the von Hippel-Lindau syndrome. We report a rare association of chorioretinal coloboma and retinal capillary hemangioma in a previously healthy patient.
Photodynamic therapy for retinal capillary hemangioma
Eye, 2013
Purpose To describe the results of photodynamic therapy (PDT) for juxtapapillary and peripheral retinal capillary hemangioma (RCH). Patients and methods Interventional case series of four eyes (four patients) with juxtapapillary RCH and one eye (one patient) with peripheral RCH. Two eyes with juxtapapillary RCH had received two sessions of full-fluence, double-duration PDT; whereas other two eyes had received single session of half-fluence, single-duration PDT. The peripheral RCH was treated with a single session of full-fluence, single-duration PDT. Results Two patients had von Hippel-Lindau disease. Follow-up duration ranged from 4 months to 1 year. Pre-PDT visual acuity (VA) ranged from 20/200 to HM (juxtapapillary RCH) and 20/100 (peripheral RCH). Among the eyes with juxtapapillary RCH, tumor regression with partial resolution of macular edema was noted in two eyes (one eye each with half-fluence and full-fluence PDT), whereas two eyes had no change in tumor size with persistent macular edema. VA remained stable in three eyes and declined in one eye. In an eye with peripheral RCH, regression of tumor and macular edema with VA improvement was noted. Post-PDT complications included epiretinal membrane (one eye) and transient exudative retinal detachment (one eye). Conclusion PDT can be effective in reducing macular edema associated with RCH but this does not always correspond with an improvement in VA especially for juxtapapillary tumors.
Vasoproliferative tumours of the retina
Eye, 2003
Background-Vasoproliferative tumours of the retina (VPTR) are benign tumours of unknown origin, occurring mostly in otherwise healthy patients. VPTR may be associated with other chorioretinal diseases, such as uveitis. The tumours, which histologically represent reactive gliovascular proliferations, are characterised by a pink to yellow appearance on funduscopy and are accompanied by exudative and haemorrhagic changes of the retina. Methods-22 cases of VPTR in 21 patients were examined with a follow up period between 1 month and 6 years. Ophthalmological changes associated with VPTR were intraretinal and subretinal exudations (n=18), exudative detachments of the surrounding sensory retina (n=13), intraretinal and subretinal haemorrhages (n=10), exudative changes within the macula (n=10), hyperpigmentation of the retinal pigment epithelium at the border of the exudative retinal changes (n=9), and vitreous haemorrhages (n=4). Tumour biopsy was performed in two cases. Treatment consisted of plaque radiotherapy (n=14), plaque radiotherapy and cryotherapy (two), cryotherapy only (two), observation (three), and enucleation in one case of a blind and painful eye. Results-Regression of the tumour and the associated exudative changes could be observed in all treated cases. Visual acuity at last follow up improved two lines or more in two cases, remained within two lines of the initial visual acuity in 15 cases, and worsened in the remaining five. Histopathological examination of the biopsy specimens and the tumour of the enucleated eye showed massive capillary proliferation with perivascular spindleshaped glial cells of retinal origin. Conclusion-The correct diagnosis of VPTR is of importance as these lesions may lead to visual loss. Further, VPTR must be diVerentiated from angiomas associated with von Hippel-Lindau disease as well as from ocular and systemic malignancies. Regression of tumour thickness and associated retinal changes can be achieved with brachytherapy or cryotherapy.
