OCT imaging of retina useful in detecting glaucoma ‘masquera
Optic nerve and macular optical coherence tomography can be helpful in distinguishing between glaucoma and glaucoma masqueraders, according to researchers.
Researchers reported a case series of 4 patients and their spectral-domain OCT findings with retinal disease or nonglaucomatous optic neuropathy, who presented with suspected or previously diagnosed normal-tension glaucoma.
The first patient was found to have marked diffuse retinal nerve fiber layer (RNFL) and macular thinning on OCT due to cancer-associated retinopathy, researchers wrote. The 76-year-old woman was referred after cataract surgery failed to relieve her symptoms of progressive vision loss.
The second patient showed deep focal inferotemporal RNFL loss with a corresponding arc of macular thinning on OCT, according to the researchers. The 60-year-old woman complained of left peripheral vision loss with a history of left carotid aneurysm that was coiled. Her IOP was 18 mm Hg in the right eye and 17 mm Hg in the left eye with central corneal thickness of 497 in her right eye and 502 in her left eye.
