FORT LAUDERDALE, Fla. – Researchers presented data here distinguishing initial paracentral defect and initial nasal defect that may help clinicians identify and manage early central vision loss in cases of open angle glaucoma.
“Disc hemorrhage was closely associated with PD superior,” Joon Mo Kim, MD, and colleagues said in a poster presentation at the Association for Research in Vision and Ophthalmology annual meeting.
In the retrospective observational study, four groups of patients included 40 patients with superior paracentral defect (PD), 37 patients with superior nasal defect, 35 patients with inferior PD and 50 patients with inferior ND.
When considering systemic factors, there was a negative association with PD superior, the study authors said. Furthermore, patients with systemic hypertension were more likely to have a nasal defect, Dr. Kim told Ocular Surgery News.
The study also found a significant association of PD superior with low maximum IOP and low IOP variation.
