Preliminary Study of the Differences in Optic Nerve Head Hemoglobin Measures Between Patients With and Without Childhood Glaucoma.

Purpose: To evaluate the effectiveness of quantifying color changes in the optic nerve head in retinal photographs of patients with childhood glaucoma.

Methods: In this observational study, three photographs of the optic nerve head were obtained in 28 patients with childhood glaucoma and 28 age- and sex-matched healthy participants (the childhood glaucoma and control groups, respectively). The Laguna Optic Nerve Head Hemoglobin (ONhE) software (Insoft SL, Tenerife, Spain) was used to determine hemoglobin levels in the optic nerve head.
