Ocular Coherence Tomographic and Clinical Characteristics in Patients of Punctuate Inner Choroidopathy Associated with Zonal Outer Retinopathy

Purpose: To describe the findings of optical coherence tomography and clinical characteristics in patients of zonal outer retinopathy associated with punctuate inner choroidopathy. Method: Review of consecutive cases on fundus photographs, spectral domain ocular coherence tomography, fluorescein angiography, indocyanine green angiography, visual field, and electrophysiological studies of patients with punctate inner choroidopathy and associated zonal outer retinopathy. Results: This study involves 4 patients suffering visual field defect far beyond the area corresponding to punctate inner choroidopathy lesions. Findings in optical coherence tomography include attenuated signals of photoreceptor inner/outer segment areas corresponding to visual field defect, and increased choroidal thickness. After treatment with immunosuppressive agents, improvements are noted in all 4 patients. Conclusion: Optical coherence tomography is helpful in the diagnosis of patients suffering zonal ocular outer retinopathy associated with punctate inner choroidopathy. All those patients responded well to immunosuppressive agents.
