Recurrent Choroidal Neovascular Membrane as the Initial Presentation of -Associated Serpiginoid Choroiditis.

PURPOSE

To report a rare presentation of a proven case of infection presenting as multifocal choroiditis with recurrent choroidal neovascular membrane (CNVM) in one eye, initially misdiagnosed as punctate inner choroidopathy and later developed serpiginous-like choroiditis in the other eye.

METHODS

Retrospective case report with a review of existing literature.

RESULTS

A 30-year-old women presented with metamorphopsia (OD) and best-corrected visual acuity (BCVA) of 6/24 (OD) and was diagnosed to have punctate inner choroidopathy with CNVM (OD). Since then, she had received four intravitreal anti-vascular endothelial growth factor injections over 3 years. Two years later, she developed a slowly progressing choroidal lesion radiating from the disc in a serpiginoid manner in the left eye. There was no vitritis. Labs revealed a positive QuantiFERON-TB Gold test. High-resolution computed tomography of the thorax showed sub-centimetre noncalcified lymph nodes in subcarinal and perivascular regions, minimal pleural thickening in left lower zone, minimal pericardial effusion, bronchiectatic changes, and fibrotic strands in right middle and left lower lobes. Bronchoalveolar lavage grew intracellularae (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry). She was given a course of clarithromycin, moxifloxacin, rifampicin, and doxycycline for 12 months. Though the right eye remained stable, choroidal lesion in the left eye continued to progress threatening the fovea, requiring oral steroids, methotrexate, and an intravitreal dexamethasone implant. At the last follow-up, her BCVA was 6/18 (OD) and 6/6 (OS). Both eyes were stable.

CONCLUSION

This case highlights a rare presentation of proven infection presenting as multifocal choroiditis with recurrent CNVM in one eye and serpiginous-like choroiditis in the other eye, requiring aggressive treatment to salvage the vision.
