Differences in anterior chamber depth in keratoconus patients with binocular very asymmetry ectasia
To evaluate the difference in anterior chamber depth (ACD) between two eyes among keratoconus patients with binocular very asymmetric ectasia (VAE) and to explore the influencing factors.

| description | To evaluate the difference in anterior chamber depth (ACD) between two eyes among keratoconus patients with binocular very asymmetric ectasia (VAE) and to explore the influencing factors.
The corneal curvature and ACD in both eyes of patients with VAE were measured by Sirius (version 3.2, CSO, Italy) at the following points: corneal vertex, maximum curvature (apex), and the 1.5 mm, 2.5 mm, and 3.5 mm superior-, inferior-, nasal-, temporal-paracentral from center. The mean pupil power (MPP) and corneal morphology parameters were also measured. Correlations between ACD and curvature and morphology parameters were analyzed by linear regression.
172 eyes of 86 patients (9 to 45 years) were classified into the VAE-N (n = 86) group and the VAE-E group (n = 86) based on the corneal morphology. The central (3.32 ± 0.27 mm versus 3.43 ± 0.29 mm, P |

The mean pupil power (MPP) and corneal morphology parameters were also measured. Correlations between ACD and curvature and morphology parameters were analyzed by linear regression.
172 eyes of 86 patients (9 to 45 years) were classified into the VAE-N (n = 86) group and the VAE-E group (n = 86) based on the corneal morphology. The central (3.32 ± 0.27 mm versus 3.43 ± 0.29 mm, P < 0.001) and paracentral ACDs increased significantly in the VAE-E group, and the corneal morphology parameters were also significantly higher. The central ACD was significantly correlated with the MPP (r = 0.465), KVf/b (Keratoconus Vertex front/back) (r = 0.306, r = 0.327), and BCVf/b (Baiocchi Calossi Versaci front/back) (r = 0.356, r = 0.416). Linear regression showed good relationships between △ACD and △MPP (R
= 0.429) and △KVf/b (R
= 0.504, R
= 0.536).
The ACD was larger in the VAE-E group. The difference in ACD between the VAE-E and VAE-N groups was significantly correlated with corneal curvature and the extent of corneal elevation, indicating the influences of both the corneal magnification effect and corneal ectasia on ACD.</description><identifier>ISSN: 1471-2415</identifier><identifier>EISSN: 1471-2415</identifier><identifier>DOI: 10.1186/s12886-024-03353-5</identifier><identifier>PMID: 38408954</identifier><language>eng</language><publisher>England: BioMed Central Ltd</publisher><subject>Anterior Chamber ; Anterior chamber depth ; Astigmatism ; Asymmetry ; Cornea ; Corneal magnification effect ; Corneal Pachymetry ; Corneal Topography ; Corneal transplantation ; Dilatation, Pathologic ; Eye surgery ; Humans ; Intraocular lenses ; Keratoconus ; Keratoconus - complications ; Keratoconus - diagnosis ; Morphology ; Myopia ; Symmetry ; Tomography ; Topography ; Very asymmetry ectasia ; Visual acuity</subject><ispartof>BMC ophthalmology, 2024-02, Vol.24 (1), p.87-87, Article 87</ispartof><rights>2024.
