[A grid pattern type of photocoagulation in treatment of diabetic maculopathy--personal experience].

PURPOSE: The aim of the present study was the evaluation of visual outcome of 425 eyes in 283 patients treated by focal and grid pattern photocoagulation for clinically significant macular edema according to the recommendations of the Early Treatment Diabetic Retinopathy Study (ETDRS). MATERIAL AND METHODS: On the basis of baseline status of macula, eyes were classified into three groups: group I--eyes treated by focal photocoagulation (39 eyes), group II--eyes treated by focal photocoagulation and/or modified grid (84 eyes), group III--eyes treated by focal photocoagulation and/or grid pattern (302 eyes). Eligibility criteria for this retrospective study included a diagnosis of clinically significant macular edema according to the ETDRS scale. The baseline examination for all patients presented in this review included: the best corrected visual acuity (VA), slit lamp with contact lens indirect ophthalmoscopy, fundus color photography and fluorescein angiography. All patients were treated with argon green by grid with Nidek 2300 laser. Modified grid or focal photocoagulation according to the ETDRS recommendations were performed. Patients with proliferative diabetic retinopathy (PDR) were transferred to panretinal photocoagulation (PRP) after treatment of maculopathy. Development of VA from the baseline to last checkup in treated eyes was reported and compared. Follow-up ranged widely from 6 to 45 months. RESULTS: General stabilization was achieved in 51.3%, improvement in 10.1% and deterioration in 38.6% of eyes. The best results were achieved after selective and focal and/or modified grid treatment: in the Ist group stabilization of VA was achieved in 43.6% and improvement in 41% of eyes; in the IInd group: stabilization in 60.7% and improvement in 21.4% were stated; in the IIIrd group: stabilization in 49.7% and improvement only in 3.0%. In 164 (38.6%) cases supplemental treatment was administered. CONCLUSION: Photocoagulation has proved effective in the treatment of diabetic clinically significant macular edema.

[Surgical correction of astigmatism after wedge resection keratoplasty].

PURPOSE: To analyse the results of astigmatism correction after keratoplasty using wedge resection technique. MATERIAL AND METHODS: Eleven patients underwent a wedge resection for postkeratoplasty astigmatism. The average postoperative astigmatism was 13.9 diopters (range 11.0 to 17.0 D). Among the patients there were 5 women and 6 men, aged 25 to 70 years. All of the grafts were in static phase, after suture removal. The indications for keratoplasty were: keratoconus--8, pseudophakic and aphakic corneal edema--3. The follow-up period after wedge resection was 6 to 24 months. The astigmatism was evaluated by videokeratometer (ORC Masterviue Ultra). RESULTS: Postoperatively, the average astigmatism was 7.25 D by 6 months, 8.1 D by 12 months, 8.45 D by 24 months. The visual acuity corrected with spectacles was 0.2 to 1.0. 8 patients (72.7%) gained better visual acuity. Complications included: 1) growing vessels through the wound, 2) delay of epithelization. CONCLUSION: Wedge resection is an effective technique for managing postkeratoplasty high astigmatism.

[Polymorphism of the chymase gene and development of retinopathy in type 2 diabetic patients].

Diabetic retinopathy is one of the major causes of blindness in developed countries. Among the factors involved in development of retinopathy genetic factors related to the generation of angiotensin II are mentioned. Recently was described that tissue chymase enzyme is the alternative trait for angiotensin II formulation. The aim of the study was assessment of association of CMA/B hCC polymorphism of chymase gene with the development and progression of diabetic retinopathy. The study was conduced in 587 type 2 diabetic patients with diabetes duration longer than 10 years. Mean age 62.8 +/- 8.58, mean duration 16.7 +/- 5.66, HbA1c 8.23 +/- 1.71, BMI 29.1 +/- 4.91. Ophthalmological examination was performed to determine the presence of retinopathy. Next polymorphism CMA/B hCC chymase gene by PCR method was assessed. Gene distribution was estimated by chi-square test. In the whole examined group no significant changes of gene distribution was found. However, in female group without retinopathy the tendency to lower incidence of GG genotype was observed (p = 0.06). When assessed the female group without retinopathy despite 15 years duration of diabetes frequency decrease of GG genotype was significant (p = 0.04). According to the results we conclude that CMA/B hCC chymase gene polymorphism is associated with the presence of diabetic retinopathy. Association is expressed by decreased frequency of GG genotype in female group without retinopathy.

[Trans-sclerally fixated PC-IOLs: six year of investigations].

PURPOSE: To present the results of PC IOLs transscleral fixation to the ciliary sulcus in six years follow-up. MATERIAL AND METHODS: 152 eyes in 3 groups: 15 eyes with primary fixations of PC IOLs, 92 eyes with secondary fixations of PC IOLs and 45 eyes with secondary fixations of PC IOLs combined with penetrating keratoplasty. RESULTS: Postoperative corrected visual acuity was 0.5 or better in 32.2% of cases, the most common complications in our material was CME (9.9%), lens tilt (4.6%) and increase of IOP (3.95%). CONCLUSION: Transscleral fixation of PC IOLs offers good visual outcome with relatively low rate of complications and is recommended in cases with inadequate posterior capsule support.

[Glaucoma after penetrating keratoplasty in the material of the ocular department of the Mountain Hospital in Sosnowiec].

PURPOSE: To evaluate the necessity of antiglaucoma therapy in patients after penetrating keratoplasty (PK). MATERIAL AND METHODS: An analysis of 537 penetrating keratoplasties performed in our department was undertaken. Incidence of glaucoma after penetrating keratoplasty procedure, necessity of pharmacological antiglaucoma treatment as well as the kind of surgical procedure and its influence on the graft transparency were estimated. RESULTS: The incidence of post keratoplasty glaucoma was 11.2% (60/537). 42 patients required pharmacological treatment (42/60) and the remaining 18 required surgery. 12 trabeculectomies, 6 drainage devices procedures and 1 cyclokrytherapy were performed and stabilization of intraocular pressure was obtained. 14 of the grafts treated surgically lost their transparency. CONCLUSIONS: Multiple surgical treatment of post-penetrating keratoplasty glaucoma, despite the stabilisation of the intraocular pressure, may lead to loss of graft transparency in most cases.

[Valve implants of glaucoma pressure regulator for refractory glaucoma: own experience].

PURPOSE: To present our experiences in valve implantation for refractory glaucoma. MATERIAL AND METHODS: From October 1993 to December 1996 implantations of Glaucoma Pressure Regulator Optimed were performed in 7 eyes of 7 patients. There were 4 men and 3 women aged from 32 to 65 years. There were 3 eyes with neovascular glaucoma due to diabetes mellitus, 2 eyes with posttraumatic glaucoma, including 1 case after keratoplasty, 1 eye with postkeratoplasty glaucoma and 1 eye with aphakic glaucoma. Preoperative IOPs ranged from 33 to 61 mm Hg (mean 37.6 +/- 7.2 mm Hg). RESULTS: Success was considered an IOP of less than 22 mm Hg without medication (complete success) or with medication (qualified success) without additional filtering surgery. Postoperative success was obtained in 4 out of 7 eyes after follow-up period of 37.4 +/- 17.08 months (range 16-39 months). Early complications were hyphema (1 patient, 14.3%), blockage of intracameral portion of the tube (1 patient, 14.3%), hypertony (1 patient, 14.3%). Late complications were: external conjunctival bleb failure (2 patients, 28.6%), blockage of intracameral portion of tube by fibrovascular tissue (1 patient, 14.3%). CONCLUSION: Our experiences confirm that the valve implant is still today an alternative surgical procedure for controlling IOP in eyes with refractory glaucoma that have visual potential.

[Evaluation of the usefulness of the laryngeal mask for general anesthesia in eye microsurgery--preliminary results].

PURPOSE: This prospective study was designed to compare intraocular pressure changes and haemodynamic response to insertion of either a laryngeal mask or an orotracheal tube during general anaesthesia for cataract surgery. MATERIAL AND METHODS: The effect of techniques (tracheal tube-TT, laryngeal mask airway-LMA) securing a clear upper airway on the heart rate changes (HR), arterial pressure (SAP, DAP), oxygen saturation (SpO2), end-tidal carbon-dioxide pressure (Et-CO2), intraocular pressure (IOP) and the incidence of coughing, stridor and sore throat was analysed in 60 patients undergoing cataract surgery during general anaesthesia. RESULTS: The mean values for HR, SAP, DAP and IOP measured before and after induction of anaesthesia were not different in both groups. After securing a clear airway, mean HR increased in TT group to 95.5/min and decreased to 75.7/min in LMA group. SAP increased in TT group to 131 mmHg, DAP to 82.6 mmHg, whilst in LMA group both values decreased to 98.6 mmHG and 66.3 mmHg, respectively. The significant difference in IOP values was observed after intubation or using laryngeal mask. In TT group, intraocular pressure increased to 15 mmHg in healthy eye and to 13.6 mmHg in ill eye whilst there was a decrease in LMA group to 5.5 and 7.43 mmHg, respectively. Furthermore, a greater incidence of such complications as coughing, stridor and sore throat in TT group was observed. CONCLUSION: The results show that using LMA in microsurgery during general anaesthesia is more advantageous and safer for patients in comparison with tracheal intubation.
