[The ultrasound findings in posttraumatic endophthalmitis].

The aim of this study was to evaluate the ultrasound findings in eyes with endophthalmitis following penetrating injury and to establish unfavorable predictive signs of this serious disease. In a retrospective study we evaluated findings in 7 eyes of 7 patients followed up because of posttraumatic endophthalmitis at the Department of Ophthalmology, School of Medicine, in Olomouc, Czech Republic, EU, during the period September 1999-December 2004. The mean age of the patients was 37.3 years (range 22-49 years). The mean duration of the period between the injury and the formation of the endophthalmitis was 8.4 days (range 1-21 days). The visual acuity at the time of admittance was very low; it ranged between light perception and 1/60 (0,016 or 20/1200). All patients underwent diagnostic-therapeutic pars plana vitrectomy with vitreous samples taken for microbiological examination and intravitreal antibiotic application. The final visual acuity (VA) ranged from 1/60 (0,016 or 20/1200) to 6/12 (0.5 or 20/40), so it was very variable and that gave us the possibility to follow the connection between the final VA and seriousness of the penetrating injury, and also with the interval between the emergence of the endophthalmitis and beginning of its treatment. During the ultrasound examination, the presence of membranes in the vitreous body, posterior vitreous detachment, thickening of the choroid, detachment of the choroid and detachment of the retina were of concern to us. Membranes were present in the vitreous in 5 eyes. Without membranes detected by the ultrasound, there were 2 eyes; in both of them the final VA was better than 6/36 (0,1667 or 20/120). The posterior vitreous detachment was detected in 3 eyes, and not detected in four eyes. We didn't find any connection between the final VA and posterior vitreous detachment. The thickening of the choroid was present at the ultrasound examination in all seven eyes. The detachment of the choroid was not found in any eye. The retina was detached in two eyes. In three eyes only, the final central VA was better than 6/36 (0.1667 or 20/120). In two of them, the intraocular foreign body was found and in both the bacteria Staphylococcus epidermidis was detected. In the third eye, the soil bacteria Enterococcus and Klebsiela were cultivated. The ultrasound findings in these three eyes are identical only in the term of thickening of the choroid, similar to other eyes. In two of them no membranes were detected by ultrasound and no posterior vitreous detachment was found. The ultrasound examination in eyes with endophthalmitis after penetrating injury is specific in particular because of the mechanism of the injury. In contrast to the cases of the postoperative endophthalmitis, no prognostic unfavorable sings in the ultrasound examination can be strictly identified.

[Ultrasound findings in endophthalmitis].

The ultrasound examination is the integral part of diagnostic procedure in endophthalmitis. During the ultrasound examination we may follow the organization of opacities in the vitreous, membranes formation, the thickening of the choroid, posterior vitreous membrane detachment, detachment of the choroid, the retinal detachment, chorideal abscess or granuloma, the edema of the optic nerve head and thickening of sclera. Not all of these ultrasound findings are always present. In our retrospective study, ultrasound findings of 17 eyes of 17 patients hospitalized at the Department of Ophthalmology at the School of Medicine, Palacký University in Olomouc during the period September 1999 - December 2002, were followed. Ultrasound findings in all eyes were evaluated and the final central visual acuity (VA) was followed. In eyes with VA 6/60 (20/200 or 0.1) or worse, the posterior vitreous membrane was not at all or only partially detached. In this group the finding of choroid thickening was more common. The finding of incomplete or absent posterior vitreous membrane detachment, and/or the thickening of the choroid might be prognostic unfavorable ultrasound finding in endophthalmitis.

The development of intracranial relations in patients with complete unilateral cleft lip and palate in relation to surgery method and gender aspect.

This study focuses on cranium development during puberty growth spurt in patients with complete unilateral cleft of the lip and palate (UCLPc) after use of various surgery methods. Next, this study focuses on cranium development differences between the genders in patients undergoing operations by the same method, as well as comparison of intracranial relations between impaired and healthy individuals. The work is based on longitudinal cephalometric measurement of X-ray films and it is interpreted by cluster analysis. It focuses mainly on mutual interrelations of linear dimensions (meaning longitudinal and vertical) with angular dimensions (characteristic of shape and position). Mutual relationships of linear characteristics were closer than its relationship with the angular characteristics and characteristics of shape and position were mutually closely related than with characteristics of the size. The development of the cranial shape in regards to the linear dimensions is influenced particularly by the depth of maxilla, the length of the ramus of the mandible, and the height of the upper face. The study confirms the least positive development of cranium in boys with a bone graft. Girls undergoing operations with the same technique have the advantage of earlier growth termination of most parts of the cranium, which makes it possible to maintain the results of the therapeutical compensation of the defect.

[Long-term experience with glaucoma silicone implants in a multicenter study].

PURPOSE: To evaluate the experience with a glaucoma implant in complicated glaucoma, designed in collaboration with the Institute of Polymers in Prague. METHODS: In a multicentric retrospective study 91 eyes of 86 patients with otherwise uncontrollable glaucoma underwent GSI implantation in four departments. The implant of medical silicone consists of a tube with an internal diameter of 0.4 mm, connected to a round lens-shaped episcleral plate 169 mm2, covering the tube orifice from above. The indications were infantile glaucoma (14 eyes), traumatic glaucoma (14 eyes), various secondary glaucomas in 12, primary open-angle glaucoma in 11, neovascular and after PPV in 10 eyes each, usually after unsuccessful previous surgery. RESULTS: The average follow-up time was 20.5 months (SD +/- 19.5). Postoperative intraocular pressure at the last control was 6-22 mmHg in 56 eyes (50.95%). Life table analysis showed a cumulative probability of 494% (at least qualified success). Long-term hypotony was seen in 6 eyes. CONCLUSIONS: The GSI is comparable with similar tube shunts but is much less expensive. In vitro experiments are planned to improve the construction of the implant and its results.

[Glaucoma drainage implants in the treatment of refractory glaucoma].

The authors describe their experience with the first three glaucoma drainage implants. All patients had previously several antiglaucomatous operations and a greatly reduced vision. The intraocular pressure was resistant to conservative treatment. In all patients the authors recorded postoperative complications reported in the literature. Glaucoma drainage implants extend possibilities in patients with refractory glaucoma.
