- Abstract
Glaucoma is an illness with high social impact, affecting more than 67 million people around the globe and one of the leading causes for irreversible blindness. OBJECTIVE: The aim of our survey is to describe the advantages of short wavelength automated perimetry- SWAP and optical coherence tomography in the early screening of glaucoma patients. MATERIAL AND METHODS: In our survey 28 patients were enrolled, which underwent a complete ophthalmologic examination, including: visual acuity, tonometry, computer perimetry and ОСТ. Perimetry was done on Humphry perimetric device with the use of both standart perimetry C 30-2 and SWAP 30-2. The screening programs on the ОСТ included: RNRL 3.45, NHM4 for estimation of the nerve fiber layer thickness, RESULTS: Only in 4 of the cases no pathological findings in OT and perimetry were found. In 6 patients with IOP in the range between 18-19 mm Hg and no changes in the perimetry on the ОСТ 3D Disk test a local thinning of the neuroretinal rim in the temporal zone was detected. On the RNFL 3.45 examination a corresponding thinning of the nerve fiber layer in 4 sectors or more was present. In18 patients with average values of the IOP between 21 - 23 mm Hg functional changes in the SWAP 30-2 perimetry were found. The ОСТ results: showed significant thinning of the nerve fiber layer in 6 sectors or more, mostly temporally and the surface topographic examination of the optic disk showed significant excavation. In all of the patients with OCT changes the Ganglion Cell Complex map showed pathological deviations- abnormal shape and colors in dark blue or black, due to the thinning of the ganglion cell layer. CONCLUSION: Short wavelength automated perimetry (SWAP) and optical coherence tomography are novel methods for detecting the earliest changes in glaucoma patients. The biggest advantage of these methods is the opportunity to detect the alterations in the ganglion cell complex, morphological (GCC map) as well as functional (SWAP) and not only focus on the nerve fiber layer or optic disk morphology. In that way they enable us to acknowledge the earliest signs of glaucoma long before ophthalmoscopic changes in the nerve head or functional defects in the perimetry appear.
