ABSTRACT Purpose: To quantitatively assess the parameters of anterior chamber and angle dimensions by anterior segment optical coherence tomography (AS-OCT) in nanophthalmos. Methods: In this prospective, cross-sectional and comparative study, 34 eyes of 34 healthy individuals (control group) and 37 eyes of 37 patients with nanophthalmos (study group) were enrolled. A single experienced ophthalmologist imaged and measured the right eye with the Visante AS-OCT. The anterior chamber angle (ACA), angle opening distance (AOD) at 500 and 750 µm from the scleral spur, and trabecular-iris space area (TISA) at 500 and 750 µm at the nasal and temporal angles were measured. Results: Mean nasal/temporal ACA was 44.90 ± 9.09/47.07 ± 8.69° in the control group and 32.15 ± 10.30/29.77 ± 10.57° in the study group (p
