Purpose: To compare the outcomes of fluorescein angiography (FA)-guided and indocyanine green angiography (ICGA)-guided half-dose photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (CSC).
Methods: In this retrospective comparative study, medical records of eyes with chronic CSC who underwent half-dose PDT were reviewed. A retina specialist performed FA-guided half-dose PDT, and the other performed ICGA-guided treatment. The success of applying PDT in the resolution of subretinal fluid was compared between the FA- and ICGA-guided methods.
Results: Eighty-two eyes of 73 patients (41 eyes in each group) received half-dose PDT. After half-dose PDT, a significant improvement in the best-corrected visual acuity (BCVA) was found at the time of the last follow-up in both groups (both 0.001), with no significant intergroup difference. Central subfield and subfoveal choroidal thicknesses decreased significantly in both groups at the last follow-up (all 0.05), with no significant differences between the groups. Subretinal fluid (SRF) resolved in all eyes, and no persistent SRF was detected during the follow-up period.
Conclusion: FA-guided and ICG-guided half-dose PDT may have similar efficacy for the treatment of chronic CSC.

Introduction: Half-dose photodynamic therapy (HD-PDT) with verteporfin is the mainstay treatment in central serous chorioretinopathy (CSC). Since 2021, there is a worldwide shortage of verteporfin. This called for adjustments of daily practice.

Article Synopsis
- The study investigates whether the thickness of anterior scleral substantia propria (ASSP) can predict responses to half-dose photodynamic therapy (PDT) in patients with central serous chorioretinopathy (CSCR) over a 3-month period.
- Conducted in multiple hospitals in Italy and Switzerland, the research involved 109 Caucasian patients, focusing on clinical data and optical coherence tomography measurements to categorize different CSCR phenotypes and their ASSP thickness.
- Results indicated that thicker ASSP is associated with complex CSCR and a higher likelihood of PDT non-responsiveness, emphasizing its potential role in understanding CSCR's severity and treatment outcomes.

Purpose: To compare the visual and anatomical results of navigated subthreshold micropulse laser (nSML) and photodynamic therapy (PDT) in the treatment of chronic central serous chorioretinopathy (CSCR).
Methods: Patients who underwent either half-dose PDT or nSML for the management of chronic CSCR were included in this study. Comprehensive ophthalmic examination, fundus autofluorescence, and spectral domain optical coherence tomography (SD-OCT) were performed at baseline and at 1-, 3-, and 6-month follow-up visits after nSML or PDT.
