Optic nerve head (ONH) examination using the Heidelberg Retina Tomograph II was carried out in a study group of 39 healthy persons aged 42-79 years. Refraction and keratometry were measured by means of the autorefractometer. The following topographic parameters of the ONH were tested: disc area, rim area and cup area, cup/disc ratio, rim/disc ratio, rim(More)
Recently discovered intrinsically photosensitive melanopsin-containing retinal ganglion cells contribute to circadian photoentrainment and pupillary constriction; recent works have also brought new evidence for their accessory role in the visual system in humans. Pupil light reaction driven by individual photoreceptors can be isolated by means of the so(More)
BACKGROUND We present the case of small-cell lung carcinoma metastatic to the iris, the course of the disease and management options. CASE A 69-year-old female was diagnosed with a solid, amelanotic iris mass in her left eye. Differential diagnostics and ancillary tests subsequently led to the diagnosis of disseminated small-cell lung carcinoma. Systemic(More)
PURPOSE Assess the possibilities of structural analysis of the optic nerve head by Heidelberg Retina Tomograph (HRT) and its use in detection of glaucomatous changes of the optic nerve in particular. Indicate the topographical parameters that are most influenced by glaucoma and are therefore vital in early diagnosis of glaucomatous changes of the optic(More)
The authors investigated changes of the intraocular pressure after non-complicated phacoemulsification with implantation of an intraocular lens of different types (OMMA, silicone, Acrysof) in 40 patients. From the results it is obvious that in some patients already 4 hours after surgery the intraocular pressure rises to an average of 31 +/- 17 mm Hg. The(More)
The purpose of this prospective longitudinal study was to investigate early defects in functional integrity of neural retina in 2. type diabetic patients without or with mild diabetic retinopathy (DR) since there is an evidence of early functional changes in neural retina before occurrence of clinical manifestation of DR. Psychophysical test of contrast(More)
The authors examined in a group of patients with cataract the visual acuity on Snellen's optotypes and contrast sensitivity using Pelli-Robson's test before cataract surgery and after cataract extraction and implantation of an intraocular lens. A VF-7 questionnaire was used for subjective evaluation of the result of surgery. The values of contrast(More)
AIM To asses the relation between the level of intraocular pressure (IOP) and central corneal thickness (CCT), and to examine the dependence of CCT on age, sex and refraction in the control group of healthy persons (CG) and the group of patients with POAG. METHODS The control group was formed by 42 eyes of healthy people and 20 eyes of patients with POAG.(More)
The authors made a retrospective study in a group of 14 patients operated in 1999 on account of pseudophakic detachment of the retina (D.R.). They followed up risk factors of development of D.R. in conjunction with complications of cataract surgery. The investigated factors comprised patients sex and age, type of cataract operation and type of implanted(More)
