ABSTRACT
OBJECTIVE:
To investigate the nationwide use of pentosan polysulfate (PPS) and screening practices for PPS maculopathy (PPM), with a focus on the timing and modalities used.DESIGN:
Population-based cohort study.PARTICIPANTS:
For evaluation of nationwide usage, 133 762 individuals who received PPS prescriptions between 2012 and 2021 were included. To investigate practice patterns, 55 487 individuals (referred to as overall users) who initiated PPS therapy between 2018 and 2020 were identified using the Health Insurance Review and Assessment database. After excluding patients with ophthalmic diseases before PPS administration, 34 857 PPS users without prior ophthalmic diseases were identified.METHODS:
Ophthalmic examinations performed after initiating PPS therapy were categorized as baseline and subsequent monitoring examinations. The timing and modalities employed for these examinations were analyzed. The annual trends in PPS utilization and maculopathy screening were evaluated by assessing the number of PPS users and determining the proportion of patients receiving retinal/macular examinations among these users. MAIN OUTCOMEMEASURES:
Performance of baseline and subsequent monitoring examinations and timing and modalities used for screening.RESULTS:
The number of PPS users dramatically increased annually over the study period from 5494 in 2012 to 40 451 in 2021. However, the majority of PPS users did not undergo baseline or subsequent monitoring examinations for PPM. Only 27.2% and 12.4% of PPS users without prior ophthalmic disease underwent baseline and monitoring examinations, respectively. Funduscopy/fundus photography was the most commonly utilized, whereas OCT and fundus autofluorescence (FAF) were performed in only 45.2% and 5.3% of the PPS users without prior ophthalmic diseases for monitoring, respectively. The performance of the screening examinations differed significantly across the 3 different daily dose and duration groups (all P < 0.05).CONCLUSIONS:
This study highlights the lack of performance of baseline and monitoring examinations for maculopathy in most patients taking PPS in South Korea. The limited use of OCT and FAF suggests potential insensitivity in detecting PPM. These findings emphasize the need for improvements in screening practices, including increased awareness and referrals to ophthalmologists, utilization of more sensitive modalities, and regular monitoring to enable early detection of PPM.
