Abstract Details


To evaluate the anterior segment biometric parameters in non-accommodative and accommodative status in refractive accommodative esotropia (RAE).


Dunya Goz Hospıtal,Ulucanlar Training Hospital, Ankara, Turkey


Eighty-one eyes of 81 patients were included in this study. The patients were divided into 3 groups as the RAE group (n=31), the hypermetropia group (n=25) and the emmetropia group (n=25). Measurements were made in the non-accommodative (0.0 D) and accommodative status (-5.0 D) with the Pentacam HR (Oculus, Germany). Pupil diameter (PD), anterior chamber depth (ACD), anterior chamber volume (ACV) and anterior chamber angle were evaluated (ACA).


The ACD, ACV and PD values in the RAE group were lower than other groups in both status (p<0.05). In the hypermetropia group PD and ACV were lower than the emmetropia group in both status (p<0.05) however ACD was lower in non-accomodative status (p=0.024) and similiar accommodative status (p=0.225). ACA was similar among theree groups (p>0.05) in both status. While all parameters did not change (Δ) significantly during accommodation in the RAE group, they was significant in the other groups. The changes were significantly lower in the hypermetropia group (p<0.05). ΔACA was did not significant and similar among theree groups (p>0.05).


The anterior chamber of RAE patients are shallower than patients with hypermetropia and emmetropia but forward movement of the crystalline lens is more limited during accommodation in RAE. Therefore posterior chamber phakic intraocular lenses (pIOLs) may be safer than anterior chamber pIOLs in these patient.
