PURPOSE: To evaluate Verteporfin photodynamic therapy (PDT) as primary treatment for small, posterior choroidal melanoma. DESIGN: Retrospective cohort review. SUBJECTS, PARTICIPANTS AND CONTROLS: Retrospective case note review of 20 patients with small juxtapapillary and juxtafoveal choroidal melanomas treated with PDT at the Liverpool Ocular Oncology Clinic. METHODS: Patient and tumour characteristics, PDT session details, visual acuity and B-scan ultrasonography measurements as well as colour fundus photographs at each examination were collated and analysed. MAIN OUTCOME MEASURES: Local tumour control and Best Corrected Visual Acuity (BCVA). RESULTS: The 20 patients (14 male, 6 female) had a mean age of 61.2 years (range, 40-85) and were treated between 2001 and 2012. Seven tumours were amelanotic, while 13 were pigmented. Of 20 melanomas, 11 (55%) showed complete regression on B-scan ultrasonography and colour photography; five (25%) showed partial regression; four (20%) remained unchanged and two (10%) showed further growth, for which alternative standard treatment was required. Baseline BCVA was 0.1 logMAR (mean; range 0.0-0.6) compared to a post-PDT BCVA of 0.4 logMAR (mean; range -0.2 to 1.7) over a follow-up of 60.0 months (mean; range 25-156 months). CONCLUSIONS: PDT can induce tumour regression in a significant proportion of small, posterior, choroidal melanomas but is less reliable than other forms of therapy. It may have a role in patients with special visual requirements if they accept the increased risk of treatment failure requiring radiotherapy.

PURPOSE: To assess the effectivity of photodynamic therapy (PDT) for the treatment of retinal capillary haemangiomas METHOD: Retrospective case note analysis of all patients with retinal angiomas treated with PDT between 2003 and 2010. RESULTS: Six eyes of 6 patients (3 male, 3 female) with a mean age of 50 years (range, 23-78) were identified in our database. The follow up period was between 24 and 60 months (mean, 36). Tumor regression was evident in two patients; three tumors showed no demonstrable response to treatment on ophthalmoscopy or ultrasonography and one tumor progressed despite PDT and subsequent cryotherapy. One patient developed retinal neovascularisations following a period of inattendence to our clinic. Visual acuity improved in two patients following PDT, deteriorated in three patients and remained stable in a one patient. CONCLUSION: The response of retinal haemangioblastomas to PDT is inconsistent. Other treatment modalities ought to be utilized for peripheral lesions, however PDT may be tried in juxtapapillary lesions where radiotherapy or cryotherapy is likely to result in concurrent visual loss.

The most common intraocular vascular tumours are choroidal haemangiomas, vasoproliferative tumours, and retinal haemangioblastomas. Rarer conditions include cavernous retinal angioma and arteriovenous malformations. Options for ablating the tumour include photodynamic therapy, argon laser photocoagulation, trans-scleral diathermy, cryotherapy, anti-angiogenic agents, plaque radiotherapy, and proton beam radiotherapy. Secondary effects are common and include retinal exudates, macular oedema, epiretinal membranes, retinal fibrosis, as well as serous and tractional retinal detachment, which are treated using standard methods (ie, intravitreal anti-angiogenic agents or steroids as well as vitreoretinal procedures, such as epiretinal membrane peeling and release of retinal traction). The detection, diagnosis, and monitoring of vascular tumours and their complications have improved considerably thanks to advances in imaging. These include spectral domain and enhanced depth imaging optical coherence tomography (SD-OCT and EDI-OCT, respectively), wide-angle photography and angiography as well as wide-angle fundus autofluorescence. Such novel imaging has provided new diagnostic clues and has profoundly influenced therapeutic strategies so that vascular tumours and secondary effects are now treated concurrently instead of sequentially, enhancing any opportunities for conserving vision and the eye. In this review, we describe how SD-OCT, EDI-OCT, autofluorescence, wide-angle photography and wide-angle angiography have facilitated the evaluation of eyes with the more common vascular tumours, that is, choroidal haemangioma, retinal vasoproliferative tumours, and retinal haemangioblastoma.
