Correlation Between Bulbar Axis Length and Retinal Ruptures in Case of Myopia Eye
Keywords:myopia, “critical”, length of bulbar axis, retinal rupture
In this study, we analysed 180 eyes with myopia in order to determine the “criticai” length of bulbar axis for the occurrence of retinal ruptures as the main cause for retinal detachment.
After the focused ophthalmological assessment, ultrasonic measurement of the bulbar axis length, indirect binocular ophtalmoscopy, we analysed diag-nosed retinal ruptures according to the shape and axis length.
Mean age of our patients was between 48,43 and to 51,60 years with SD ranging from 13,88 to 18,45. The study included 102 (56,6%) male and 78 (43,3%) female patients; there was no statistically significant difference regarding the occurrence of retinal ruptures between male and female patients compared to the axis length. Most dominant was round (28,2%), then oval (25%) category - multiple small ruptures (19,2%), and horseshoe-shaped (15,3%), and finally the ruptures with operculum.
We consider the length of bulbar axis ranging from 24,52 mm to 26,51 mm to be a predictive factor in the occurrence of retinal rupture, and later in retinal detachment.
