[Outcome results in macular hole surgery with internal limiting membrane removal].

PURPOSE: To determine the visual outcome and anatomic closure rate of macular hole surgery using pars plana vitrectomy with internal limiting membrane (ILM) peeling. MATERIAL AND METHODS: Fifty three eyes of 52 consecutive patients with a full-thickness idiopathic macular holes (stage 3 or 4). All eyes underwent a pars plana vitrectomy including separation of the posterior hyaloid, ILM peeling with trypan blue (TB) or indocyanine green (ICG) and gas endo-tamponade with instructions to the patient, to be face down for 4-5 days. Postoperative anatomic results, visual acuity (VA), and complications were recorded. The follow-up was 3 to 22 months. RESULTS: VA improved postoperatively in 45 eyes (84.9%), at least two lines on the Snellen chart in 24 eyes (45.3%). It remained unchanged in 6 eyes (11.3%) and deteriorated in 2 eyes (3.80%). The mean preoperative VA was 0.1 +/- 0.04 and does not differ significantly between stage 3 and 4. The improvement of postoperative VA was statistically significantly better in stage 3, in comparison to stage 4. The anatomical success rate (flat/closed) was 88.7% (47 eyes). There were no differences in VA improvement between TB- or ICG-stained eyes. CONCLUSIONS: 1. Vitrectomy with ILM removal in macular holes provides with meaning improvement in visual acuity. 2. Patients with macular hole in stage 3 have a better prognosis for visual rehabilitation. 3. A kind of dye and preoperative VA do not influence postoperative visual function improvement.

[Glaucoma Service Database].

We present the common problems related to clinical databases. The Glaucoma Service Database created in our clinic is an attempt of developing the optimal medical database. The system organizes our repository of clinical data. It consist of 3 modules: 1) the users list with predefined privileges and rights, 2) lists of coded data for further use, that facilitate filling in the fields, 3) clinical details of all patients. The user interface of our database is very simply, thus it is very easy to use it even by unskilled staff. The accuracy of data is protected by system's internal algorithms. It could be used to investigate clinical epidemiology, risk assessment, post-marketing surveillance of drugs, practice variation and decision analysis. Data from Glaucoma Service Database can also help in the management of health service.

[The comparative analysis of changes in optic disc morphology after trabeculectomy, measured by scanning laser tomography].

PURPOSE: The aim of this study was to investigate and estimate quantitative changes in optic nerve morphology after glaucoma surgery using the Heidelberg Retina Tomograph (Heidelberg Engineering, HRT Software 2.01). MATERIAL AND METHODS: The eyes of 42 consecutive patients (34 women and 8 men) undergoing trabeculectomy at the Department of Ophthalmology, Wroclaw Medical University, were enrolled into the study. Quantitative analysis of the optic nerve head parameters by scanning laser tomography were performed, as well as automated perimetry, before and after surgery. Post operative HRT images were obtained at 2-3 weeks, 4-6 months, 9-12 months and > 12 months after surgery. RESULTS: Forty one patients (97.6%) have obtained postoperatively IOP reduction greater than 30%. Two weeks after trabeculectomy seven HRT parameters showed statistically significant improvement: CA, CV, RA, RV, mean cup depth, CSM. Approximately 5 months after surgery only 2 parameters (mean cup depth & CSM) were statistically changed, as well as 12 months after surgery (mean and max cup depth), which cannot be explained by postoperative disc edema. A corresponding change was also noted in the visual field. There was no statistically significant association between optic disc morphology as measured by HRT and the degree of intraocular pressure reduction. CONCLUSION: All patients showing a 30% lowering of IOP after glaucoma surgery show improved optic nerve morphology as measured by the HRT. Further studies are required to provide information, to what extent the change in optic disc topography is dependent on the duration of elevated intraocular pressure or advanced stage of glaucomatous optic neuropathy.
