Postoperative care for patiens after vitrectomy with focus on secondary glaucoma The first part of the thesis discusses the relationship between the occurence of secondary glaucoma (SG) after pars plana vitrectomy (PPV) and individual surgical techniques, taking into consideration functional outcomes of the treatment - visual acuity and intraocular pressure (IOP). SG after PPV occurred in 126 eyes, i.e. in 16,5%. In all patients with SG a meticulous ocular examination was carried out after 3, 6, 12 and 18 months, and a final examination after 43,6 months. Overall 69% of eyes with SG underwent a PPV because of retinal detachment and 19,8% because of vitreous hemorrhage. High viscosity silicon oil tamponade (SO) was employed in 75,4% of eyes, low viscosity tamponade in mere 1,6% of eyes, a tamponade by SF6 gas in 10,3% of eyes and by BSS solution in 12,7% of eyes. Following are the functional outcomes of the treatment: a) visual acuity improved from 0,1 to 0,2, however, by the final examination we registered an increase of incerta caused by decompensation of eyes with secondary neovascular glaucoma (SNVG); b) after a year 74,6% of eyes showed a stabilized IOP of ≤ 22 mm Hg, after 18 months 76,7% and by the final examination 81,8%; c) by the final examination 26,4% of eyes did not require any...

Eutrophication trends in the Vltava catchment area, Czech Republic

Long-term trends in phosphorus and phytoplankton concentrations were studied in Slapy Reserv.,as a representative of most reservoirs with medium flushing rate in the Czech Rep. Phosphorus and chlorophyll a concentrations increased from the 1950s to the middle 1990s as a consequence of an increase of phosphorus use and release into surface waters by human population. The decrease in phosphorus and chlorophyll a concentrations during the last decade can be interpreted as a beginning of a long-term recovery of Slapy Reservoir resulting from the decrease in P-loading into the surface waters by human population. Further possibility how to reduce phosphorus input to the surface waters is especially P removal from municipal waste waters. After higher reduction of phosphorus from waste waters, accomplishable especially by the entire elimination of P from detergents and by technologies of enhanced P removal in waste water treatment facilities,the trophic status of Slapy Reserv. lower than in the 1950s can be expected.
