NCT05390619

Brief Summary

This is a prospective, randomized and controlled clinical trial of photodynamic therapy (PDT) for chronic central serous chorioretinopathy (CSC). The patients who met the inclusion criteria were randomly divided into 50% dose PDT treatment group and 70% dose PDT treatment group. The primary treatment success rate and adverse event rate of the two groups were compared by optical coherence tomography (OCT), and then the best PDT treatment scheme for chronic CSC was summarized.

Outcome Measures

Primary Outcomes (1)

  • The complete absorption rate of subretinal fluid

    The absorption of subretinal fluid was observed on optical coherence tomography at each follow up visit

    3 months after the primary PDT

Secondary Outcomes (3)

  • Central foveal thickness change after the PDT

    12 months after the PDT

  • Subfoveal choroidal thickness change after the PDT

    12 months after the PDT

  • Best corrected visual acuity change after the PDT

    12 months after the PDT

Study Arms (2)

50% dose of PDT

EXPERIMENTAL

Patients received 50% dose of verteporfin PDT therapy.

Procedure: 50% dose of photodynamic therapy

70% dose of PDT

EXPERIMENTAL

Patients received 70% dose of verteporfin PDT therapy.

Procedure: 70% dose of photodynamic therapy

Interventions

Verteporfin (Visudyne; Novartis, Switzerland) was administrated intravenously over 10 minutes with 50% doses based on the randomization . Fifteen minutes after commencing the verteporfin infusion, a contact lens (Volk® area centralis) was positioned on the affected eye, the treatment area was exposed to a 689 nm laser with a fluence of 600 mw/cm2 for 83 seconds and a total laser energy of 50 J/cm2.
