[The benefit of pars plana vitrectomy for the resolution of complications of proliferative diabetic retinopathy]. / Prínos pars plana vitrektomie pro resení komplikací proliferativní diabetické retinopatie.

Between 1997 and 2007, we have conducted eye surgery on 72 patients (i.e. 72 eyes) as a consequence of proliferative diabetic retinopathy complications. The patients' average age was 61; the follow-up observations were carried out over a period of one year after the surgery. When we compare the initial vision with the visual acuity measured during the last follow-up examination in the late post-operative period, i.e. one year after the surgery, we can conclude that the vision of46 eyes (63%) had improved, 17 eyes (24%) did not show any change in vision, and the vision of nine eyes (13%) had deteriorated. Visual acuity of 1/60 (metric system) or better was found in 55 eyes (76%) during the late post-operative period; 6/60 vision or better was found in 29 eyes (40%), and four eyes (6%) showed 6/12 vision or better. If we compare the vision in the early post-operative period with the visual acuity during the last follow-up examination in the late post-operative period, we can conclude that in most cases, i.e. in 45 eyes (62.5%), the vision did not change any further during the months after the surgery, and one eye (1.5%) even showed improvement in visual acuity. It was confirmed that a positive result of pars plana vitrectomy observed in the early post-operative period may indeed persist even during the following months and years of the patient's life.

[Anatomical results of cryosurgical procedures in rhegmatogenous retinal detachment - our experience]. / Anatomické výsledky kryochirurgických operací pri rhegmatogenním odchlípení sítnice - nase zkusenosti.

AIM: To evaluate retrospectively anatomical results of cryosurgical treatment of non-complicated idiopathic rhegmatogenous retinal detachment. To assess the successfulness of primary cryosurgical surgeries, permanent retinal re-attachment; to review the efficacy of cryosurgical procedures according to chosen surgical technique and patients age as well. MATERIAL AND METHODS: In the evaluated group were included 120 eyes of 120 patients operated on in the years 2003- 2012 at the Department of Ophthalmology, Faculty Hospital and School of Medicine, Palacký University, Olomouc, Czech Republic, E.U. All of the patients were phakic. The patients were evaluated at one and three months after the surgery. The posterior pole examinations were done by means of biomicroscopic examination and indirect ophthalmoscopy. The retina was evaluated as attached in whole extent in case of re-established contact between the neurosensory retina and the retinal pigment epithelium in the whole periphery. RESULTS: In 106 (88 %) patients, the re-attachment of the retina was achieved by solely cryosurgical procedure; in 117 (97.5 %) patients, the definite re-attachment of the retina was achieved. In three patients (2.5 %), the retina remained detached. Statistically better results were obtained in patients with peroperative exodrainage of the subretinal fluid and in patients younger than 50 years of age. CONCLUSION: We established the usefulness of cryosurgical operative procedure in treatment of uncomplicated idiopathic rhegmatogenous retinal detachment in phakic patients. Especially in young phakic patients, the cryosurgical procedure may be protective to preserve the clear lens and eye accommodation.

[Functional results of cryosurgical procedures in rhegmatogenous retinal detachment including macula region - our experience]. / Funkcní výsledky kryochirurgických operací pri rhegmatogenním odchlípení sítnice vcetne makuly nase zkusenosti.

AIM: Aim of this study is to evaluate retrospectively functional results of cryosurgical treatment of uncomplicated, idiopathic rhegmatogenous retinal detachment including macula region in phakic patients operated on at the Department of Ophthalmology, Faculty Hospital, Palacký University, Olomouc, Czech Republic, E.U., during the period 2002 -2013, and to evaluate the significance of the macula detachment duration for the final visual acuity. METHODS: In the study group were included 56 eyes of 56 patients operated in the years 2003 - 2012 at the Department of Ophthalmology, Faculty Hospital, Palacký University, Olomouc. All patients were phakic and in all of them, the retinal detachment including the macula region was diagnosed. The mean follow-up period of the patients was 8,75 months. The initial and final visual acuity testing were performed. Comparing the initial and final visual acuity we rated the level of the visual acuity change. The result was stated as improved, if the visual acuity improved by 1 or more lines on the ETDRS chart. The result was rated as stabilized, if the visual acuity remained the same or it changed by 1 line of the ETDRS chart only. The result was evaluated as worsened, if the visual acuity decreased by 1 or more lines of the ETDRS chart. In the followed-up group, the authors compared visual acuity levels in patients with the macula detachment duration 10 days and 11 days. For the statistical evaluation of achieved results, the Mann - Whitney U test was used. RESULTS: The visual acuity improved in 49 (87 %), did not changed in 5 (9 %) and worsened in 2 (4 %) patients. The patients with macula detachment duration 10 days achieved statistically significant better visual acuity than patients with macula detachment duration 11 days. CONCLUSION: Patients with macula detachment duration 10 days have better prognosis for functional result than patients with macula detachment duration 11 days.
