[Astigmatism after extracapsular cataract extraction with intraocular posterior lens implantation]. / Niezbornosc po operacji zewnatrztorebkowego usuniecia zacmy z wszczepem tylnokomorowym.

PURPOSE: To evaluate early and late astigmatism appearing after extracapsular cataract extraction with PC IOL implantation. MATERIAL AND METHODS: Astigmatism was examined in one hundred consecutive patients before operation and one week, 6 months and 12 months postoperatively. RESULTS: During the first week after surgery most patients (82%) had with the rule astigmatism, which decreased gradually from 3.95 D cyl (mean value) to 0.08 D cyl after a year. Against the rule astigmatism was present in 14% of cases and increased from 2.40 D cyl (mean value) to 3.07 D cyl in the same period of time. On the last examination 35% of patients didn't use any astigmatic correction. CONCLUSIONS: Traditional ECCE with PC IOLs causes postoperative astigmatism in most patients. Majority of them has with the rule astigmatism, which decreases gradually during the first postoperative year and may change into against the rule astigmatism.

Pars plana vitrectomy, lensectomy, or extraction in transscleral intraocular lens fixation for the management of dislocated lenses in a family with Marfan's syndrome.

BACKGROUND AND OBJECTIVES: Congenital lens subluxation may be a difficult therapeutic problem. Surgical treatment options include iris manipulation or lens decision, aspiration, intracapsular or extracapsular extraction, and lensectomy through the pars plana. It is not established which kind of aphakic correction is the most appropriate in these cases. PATIENTS AND METHODS: A father and his two sons with Marfan's syndrome were operatively treated for lens dislocation in both eyes. Pars plana vitrectomy was done in all eyes. Dislocated lenses were removed by lensectomy in three eyes and with an intracapsular method in three eyes. The outside-in scleral fixation technique was used for primary posterior chamber intraocular lens (PC IOL) implantation in all cases. RESULTS: All eyes achieved good visual acuity (20/20-20/25). Time of observation ranged between 8 and 20 months. There were no intraoperative or post-operative complications. CONCLUSION: Pars plana vitrectomy and primary scleral-fixated IOL implantation is a safe procedure and gives good visual rehabilitation in adult patients with Marfan's syndrome.

[Current views on the pathogenesis and treatment of central serous choroidopathy]. / Wspólczesne poglady na patogeneze i leczenie srodkowej, surowiczej choroidopatii.

The majority of authors as a cause of formation of a leakage in central serous choroidopathy considers the disturbances of function of the pigmentary layer. According to Spitznas it is based on transformation of these cells from absorbing to extracting towards the choroid and retina under the influence of unknown factors (immunological processes, circulatory, inflammatory factors or stress). Marmor sees the lesion of the pigmentary epithelium as a disturbance of a cyclic action of the AMP neeth the neurosensory layer of the retina. There exist contemporary 2 methods of treatment of the central serous retinopathy. One part of the authors thinks that one should wait till the spontaneous remission, the other one--that in cases with the leakage situated beyond the risk area laser therapy can be applied.

[The role of laser therapy in central serous choroidopathy]. / Rola laseroterapii w srodkowej, surowiczej choroidopatii.

The authors present early results of treatment of central serous choroidopathy by means of argon laser. Additionally they compare the fate of the patients with this condition treated conservatively in the last years. The results obtained confirm the world reports that application of laser in therapy of central serous choroidopathy shortens the course of the disease.
