ABSTRACT
OBJECTIVE: To describe unusual cause of diplopia in early puerperal period. DESIGN: Case report. SETTING: Department of Obstetrics and Gynecology, 2nd Faculty of Medicine and Faculty Hospital Motol. CASE REPORT: 34-year-old patient at 39 weeks of gestation complaining fever, headache and blurring of vision was referred to our medical center. She underwent caesarean section for tachycardia of fetus. Symptoms remained during early puerperium. We describe diagnostic and treatment hesitations. CONCLUSION: The cause of her complains was viral meningoencephalitis which led in postencephalitic syndrome.

PURPOSE: To evaluate quality of life and visual functions in patients with keratoconus wearing rigid gas permeable (RGP) contact lenses. METHODS: Keratometry and objective refraction, uncorrected visual acuity, visual acuity with RGP contact lens, high order aberrations and letter contrast sensitivity before and after RGP application were measured in 22 keratoconus patients. Vision-related quality of life was examined by the National Eye Institute Visual Function Questionnaire (NEI-VFQ 25) RESULTS: The average spherical equivalent in the study group was -7.28 (+/- 5.53), the average keratometry was 50.04 D (+/- 4.24) and the average corneal astigmatism -3,44 Dcyl (+/- 2,72). The uncorrected visual acuity was 0.20 (+/- 0.18), the corrected visual acuity 0.78 (+/- 0.22). The improvement of visual acuity after RGP fitting was statistically significant (p < 0.001). The RGP fitting didn't cause significant changes in high order aberrations and in contrast sensitivity. The NEI-VFQ overall score was 79.2. Keratoconus was associated with lower scores in these categories: dependency, mental health and ocular pain. CONCLUSION: Keratoconus is a disease which may have a marked impact on the quality of life beacuse it affects young adults in their active years. The use of RGP correction can significantly improve visual acuity but, at least in our study group, did not lead to significant improvement in contrast sensitivity and corneal aberrations.

Cornea is the most important refractive medium of the eye and affects its total aberration state. This paper deals with corneal higher order aberrations in healthy humans and evaluates their changes with aging and corneal curvature. The influence of the corneal anterior and posterior surfaces on aberrations of the whole cornea was also investigated. The examination was performed with a Scheimpflug camera which enables to examine the anterior and posterior corneal surface separately. The results show that higher order aberrations of the whole cornea are influenced mainly by the anterior surface aberrations. The main corneal higher order aberration is the Z (4,0) spherical aberration which has a positive value and increases with age. Also, 3rd order aberration values are of importance, especially coma which also increases with age. As a consequence, the root-mean-square of the 3rd and 4th order aberrations in elderly people has a higher value.
