Sažetak
In the past few years many new diagnostic methods for diagnosing and monitoring glaucoma have appeared, such as Heidelberg Retina Tomograph (HRT), Optical Coherence Tomography (OCT) and Scanning Laser Polarimetry (GDx). With this review we wanted to evaluate the use of Heidelberg Retina Tomograph (HRT2) in early glaucoma detection and we wanted to show that in some patients with diagnosed preperimetric glaucoma we can detect structural changes of the optic nerve head (ONH) with the help of HRT2. We evaluated a group of patients who did not experience any changes in visual field but who had early changes of ONH, which was discovered by a quantity orphological analysis of ONH with the help of confocal laser scanning system. Patients included in the analysis had intraocular pressure (IOP) above 21mmHg as measured with Goldmann applanation tonometer. The appearance of the ONH was clinically abnormal with localized or general damage of optic nerve fibers and cup/disc ratio above 0.7. Visual field assessment was performed by Humphrey Field Analyzer (24-2 full threshold strategy) and showed no visual field defects. Scanning of ONH was performed by HRT2 scanning laser ophthalmoscope. The analysis of appearance of scanned ONH was performed using Moorfields Regression Analysis (MRA). According to MRA of the scanned optic nerve head for the above mentioned patients, ONH was outside normal distribution range. In conclusion, we want to accentuate the importance of considering all of the parameters for diagnosing glaucoma in clinical praxis. With new diagnostic methods such as HRT2 we can get an additional parameter that should be included in the glaucoma diagnostic algorithm.
