POLYPOIDAL CHOROIDAL VASCULOPATHY ASSOCIATED WITH SECTOR RETINITIS PIGMENTOSA.

Area of Science:

• Ophthalmology
• Retinal Diseases
• Choroidal Vasculopathy

Background:

• Sector retinitis pigmentosa (RP) is a genetic retinal disorder.
• Polypoidal choroidal vasculopathy (PCV) is a pachychoroid vascular condition.

Observation:

• A 63-year-old woman presented with progressive vision loss in her left eye.
• Fundus examination and multimodal imaging revealed sector RP in both eyes and active extramacular PCV in the left eye.
• Choroidal thinning was noted in both eyes via spectral-domain optical coherence tomography (SD-OCT).

Findings:

• The patient received an intravitreal bevacizumab injection in the left eye.
• One month post-treatment, visual acuity in the left eye remained stable.
• SD-OCT confirmed reduced subretinal fluid and polypoidal lesion size.

Implications:

• PCV may be associated with RP, particularly in cases with thin choroids.
• Multimodal imaging is essential for differentiating PCV from Type-1 macular neovascularization.
• This case highlights the importance of comprehensive imaging in complex retinal cases.
