Abstract

S obzirom na problematiku izračunavanja duljine očne jabučice ispunjene silikonskim uljem danas ne postoji optimalna metoda koju možemo smatrati zlatnim standardom.
Cilj ovog rada bio je usporediti točnost mjerenja aksijalne duljine očne jabučice ispunjene silikonskim uljem uz pomoć magnetske rezonancije i optičke koherentne biometrije.
U ovu prospektivnu randomiziranu studiju bilo je uključeno 69 bolesnika, od kojih su 35 bolesnika pripadali skupini kojoj je biometrija načinjena pomoću magnetske rezonancije ( B skupina ili MR skupina), a 34 bolesnika skupini kojoj je izračun biometrije načinjen pomoću optičke koherentne biometrije (A skupina ili Master skupina).
Kod MR skupine medijan odstupanja od stvarne poslijeoperacijske refrakcijske greške iznosi 0,50 D, dok kod Master skupine 1,19 D. Razlika izmeĎu skupina statistički je značajna (p=0,01).
Prema dobivenim podacima ove studije biometrija pomoću magnetske rezonancije je točnija metoda za mjerenje aksijalne duljine očne jabučice ispunjene silikonskim uljem u odnosu na optičku koherentnu biometriju. Time je točnija i za izračunavanje potrebne jačine intraokularne leće prije operacije katarakte ukoliko se MR biometrija radi s presjecima od 1,5 mm, a zbog značajno

manjeg odstupanja od ciljane refrakcijske greške u odnosu na optičku koherentnu biometriju.

Abstract (english)

Given the problems of calculating the length of the silicone oil filled eyes, there is no optimal method that can be considered the golden standard at this moment.
The aim of this study was to compare the accuracy of the axial length measurement of silicone oil filled eyes, using optical coherent biometry and magnetic resonance imagining.
This prospective randomized study included 69 patients, of whom in 35 patients biometry was done using magnetic resonance (A or MR group), while in 34 patients biometry was performed using optical coherent biometry (B or Master group)
The median deviation of the final from the predicted refraction in the MR group was -0,50 D, and in the Master group 1,19 D. The difference between groups was statistically significant (p = 0.01).
According to the data of this study, magnetic resonance imagining is a more accurate method for measuring the axial length of the silicone oil filled eyes compared to the optical coherent biometry. It also showed a more accurate intraocular lens power calculation before phacoemulsification and evacuation of silicone oil regarding smaller deviation from the final refraction, if the imagining is done with sections of 1,5 mm.
