PURPOSE: To report long term results of photodynamic therapy (PDT) as treatment for intraocular tumors METHODS: Retrospective interventional case series of 15 patients. All patients treated with standard-fluence PDT (83 s; 50 J/cm2) using verteporfin.
OUTCOME MEASURES: Tumor diameter, tumor thickness, subretinal fluid resolution, best-corrected visual acuity,intraocular pressure and PDT complications.
RESULTS: 10 patients (66.7% of total patients) were diagnosed with choroidal hemangioma, 3 patients (20% of total patients) were diagnosed with choroidal melanoma, and 2 patients (13,3% of total patients) were diagnosed with choroidal osteoma.. Mean follow-up time was 33±18 months. The mean visual acuity was determined as 1.29 ± 0.98 logMAR in the examinations just before the PDT application. At the end of the follow-up period, the mean visual acuity was calculated as 1.41 ± 1.07 logMAR. While VA increased in 3 (20%) patients and decreased in 5 (33.3%) patients; It was determined that VA value did not change after treatment in 7 (46.7%) patients. The mean lesion diameter before PDT was 6573 ± 2115 µm (range; 1500-10,000 µm). The mean tumor thickness before PDT was 3624 ± 1404 µm (range; 600-6000 µm). The mean lesion diameter after treatment was 6026 ± 2521 µm (range; 0-9000 µm), and the mean tumor thickness after treatment was 2280 ± 1740 µm (range; 0-6000 µm).After the PDT, tumor size decreased in 8 (53.3%) patients, increased in 3 (20%) patients, and no change in tumor size was observed in 4 (26.7%) patients. Mean IOP values of all patients were 14.06 ± 3.17 mmHg before treatment; after treatment, it was measured as 13.46 ± 1.70 mmHg. After the treatment, geographic atrophy developed in 1 (6.7%) patient, cystoid macular edema developed in 1 (6.7%) patient, Retinal Pigment Epithelium (RPE) and choroidal atrophy developed in 1 (6.7%) patient.
CONCLUSION: There are not enough cases of each to clearly distinguish between these 3 types of ocular cancers.However PDT may be a good option in the treatment of intraocular tumors with the chance of selective treatment and successful response.
