To evaluate the ocular refractive and biometric characteristicsin patients with tilted disc syndrome (TDS).
This case-control study comprised 41 eyes of 25 patients withestablished TDS and forty eyes of 20 age- and sex-matched healthycontrol subjects. All had a complete ocular examination includingrefraction and analysis using Fourier transformation, slit lampbiomicroscopy, pachymetry, keratometry, and ocular biometry.Corneal topography examinations were performed in the syndromegroup only.
There were no significant differences in spherical equivalent(p = 0.334) and total astigmatism (p= 0.246) between groups.However, mean best spectacular corrected visual acuity was significantlyworse in TDS patients (P < 0.001). The lenticular astigmatismwas significantly greater in the syndrome group, while the cornealcomponent was greater in the controls (p = 0.004 and p = 0.002,respectively). The measured biometric features were the samein both groups, except for the lens thickness, relative lensposition, and lens-axial length factor which were greater inthe TDS group (p = 0.002, p = 0.015, and p = 0.025, respectively).
Clinically significant lenticular astigmatism, more obliquecorneal astigmatism, and thicker lens were characteristic findingsin patients with TDS.
