Retinal pigment epithelial tear in polypoidal choroidal vasculopathy

Area of Science:

• Ophthalmology
• Retinal diseases
• Choroidal neovascularization

Background:

• Polypoidal choroidal vasculopathy (PCV) is a common subtype of exudative age-related macular degeneration.
• Pigment epithelial detachments (PEDs) are characteristic findings in PCV.
• Tears in the retinal pigment epithelium (RPE) are not well-characterized in the context of PCV.

Purpose of the Study:

• To investigate the clinical features of RPE tears in eyes diagnosed with PCV.
• To understand the relationship between RPE tears and PEDs in PCV patients.

Main Methods:

• Retrospective case series of eight eyes from eight patients with PCV and RPE tears.
• Clinical examination, fluorescein angiography, and optical coherence tomography (OCT) were utilized.
• Follow-up data on visual acuity and RPE tear development were analyzed.

Main Results:

• RPE tears were observed at the margin of serosanguineous PEDs in all eight eyes with PCV.
• Tears occurred spontaneously in some eyes and after photodynamic therapy in others.
• RPE tears were located opposite the polypoidal lesions and did not involve the fovea.
• Visual acuity varied, with some eyes experiencing vision loss during follow-up.

Conclusions:

• RPE tears are a potential complication in eyes with PCV, associated with serosanguineous PEDs.
• These tears can arise spontaneously or secondary to treatments like photodynamic therapy.
• Further research is needed to understand the long-term visual implications of RPE tears in PCV.
