{Abstract}: <B>OBJECTIVE: </B>To evaluate the efficacy of half-dose photodynamic therapy (PDT) for the treatment of bullous retinal detachment.<BR><B>METHODS: </B>Interventional prospective case series in six eyes from six consecutive patients with bullous retinal detachment. The effected eyes were treated with indocyanine green angiography (ICGA)-guided half-dose PDT with multifocal and large laser spots. Clinical evaluations included best-corrected visual acuity (BCVA), ophthalmoscopy, ophthalmic B scan, fundus fluorescein angiography (FFA), optical coherence tomography (OCT), and ICGA at each scheduled visit at baseline; at 1, 3, and 6 months after PDT; and during follow-up after 6 months.<BR><B>RESULTS: </B>All six eyes received half-dose verteporfin PDT with a mean number of therapeutic spots 2.83 ± 1.47 and a mean spot size of 4647 ± 996 μm in diameter. Three months after PDT, retinal reattachment was observed on B scans and resolution of sub-retinal fluid (SRF) was observed in OCT images for five eyes. There was no significant difference in the mean logMAR BCVA between the baseline and the value at 1 month after PDT (P = 0.477). At 3 months after PDT, the mean logMAR BCVA improved significantly from a baseline value of 1.02 to 0.54 (P = 0.044). At 6 months after PDT, the mean logMAR BCVA further improved to 0.46 (P = 0.025) and remained stable. One affected eye received a second half-dose PDT for SRF not reduced until the second month after PDT. Retinal reattachment and SRF resolution were observed at 1 and 3 months after the second therapy, respectively. BCVA improved from a baseline value of 20/63 to 20/20 at 1 month after the second PDT and remained stable until the sixth month after the second PDT. During follow-up after more than 6 months, recurrence occurred in no cases.<BR><B>CONCLUSIONS: </B>This study demonstrated half-dose PDT with multifocal and large laser spots was an effective treatment for bullous retinal detachment contributing to the retinal reattachment, a resolution of SRF, and an improvement of BCVA. Thus, PDT for the treatment of bullous retinal detachment is considered to be a worthwhile endeavor.
