RESUMO

The aim of this work was to study the clinical and optical results and safety of anterior chamber phakic intraocular lenses in patients with high myopia. Seventeen eyes of 11 patients with myopia ranging between -10.5 to -24 D were included in the study. Uncorrected visual acuity, best spectacle corrected visual acuity, refraction, spherical equivalent, astigmatism, intraocular pressure, papillary ovalization and central corneal thickness were studied before the operation and after week, one month, six months and one year. Endothelial cell count was done before surgery and one year after surgery. Uncorrected visual acuity, best spectacle corrected visual acuity, refraction and spherical equivalent showed statistically significant improvement, which lasted throughout one-year follow up. Temporary changes in intraocular pressure, central corneal thickness and astigmatism were noted, but were restored later to mean preoperative levels. Endothelial cell count decreased significantly from the preoperative levels, but was not less than 2000/mm2. In one case, the lens had to be explanted due to chronic inflammatory reaction

RESUMO

The aim of this study was to compare disc topographic measurements by manual- and computer-assisted planimetry of optic disc photographs. For 20 patients with glaucoma and 15 normal subjects, the optic disc photographs were evaluated by manual and computer assisted planimetry. The results indicated that absolute rim area and rim to disc area were significantly larger with manual- than with computer-assisted planimetry of disc photographs in glaucomatous patients. Coefficients of correlations between disc topographic measurements of both methods were r=0.81 [glaucoma] and 0.81 [normal] for rim area, r=0.67 [glaucoma] and 0.62 [normal] for rim to disc area and r=0.78 [normal] and 0.66 [glaucoma] for total disc area. It was concluded that the parameters of optic disc topography vary widely with different methods of measurement. So, currently used parameters were revised when more accurate and meaningful parameters become available to characterize the optic nerve and its pathologically induced changes
