[Age related macular degeneration surgery].

Age related macular degeneration (ARMD) is a disease in which the retinal pigment epithelium (RPE) is damaged in the central retinal area. In the exudative form, the vision loss is due to choroidal neovascularization, while in the nonexudative or atrophic form, there is a vision loss because of the retinal pigment epithelium atrophy. Treatment which proved to be efficient in lowering the risk of severe vision loss in the exudative form includes laser photocoagulation, photodynamic therapy, transpupilary thermotherapy and as surgical treatment, the controversial subretinal membrane extraction. In all these situations the RPE is damaged by the disease itself and by the therapeutic procedure too. Retinal translocation is a surgical procedure that intends to remove the neurosensory retina from an area with damaged RPE to an healthy RPE area, through a 360 degrees retinotomy or through a limited one. This paper present some ARMD cases treated by subretinal membrane extraction and one by limited retinal translocation. The question which is still remaining is which are the risks and benefits for the following treatment procedures: laser photocoagulation, photodynamic therapy, transpupilary thermotherapy and surgical approach?

[Posterior capsule rupture in lens surgery].

PURPOSE: The paper studies the breaks of the posterior capsule in lens surgery, specifically the incidence, causes, types, management and the methods of IOL implantation. METHODS: For this purpose, a retrospective clinical trial was performed, within: 01.06.1999-31.05.2002, on 346 eyes group operated for senile cataract (without other ocular diseases) Patients were split in two groups, based on surgical technique: group 1 with 208 eyes operated using phacoemulsification and group 2 with 138 eyes operated using extracapsular extraction technique. RESULTS: The incidence of the breaks of the posterior capsule was 8.17% for group 1 (17 eyes out of 208) and 5.07% for group 2 (7 eyes out of 138). In all cases an IOL was used, most of them being placed in the posterior chamber (in bag, in sulcus or sclera-sutured) and infrequently IOL for anterior chamber or with irian support. CONCLUSIONS: Breaks of the posterior capsule is a complication of cataract surgery, but appropriate management (viscoelastic substances, anterior vitrectomy) leads to a good outcome, with no influence on the subsequent evolution.

[Primary open angle glaucoma evolution after surgery].

The authors present a four year (01.02.1998-01.02.2002) clinical retrospective trial, including 209 eyes operated for Primary Open Angle Glaucoma (POAG). 52 eyes (24.8%) out of 209 eyes the progression of the disease was discovered observing the increase of the intraocular pressure (IOP), failure in achieving "IOP target" due to the insufficient filtration, the obstruction of the filtration and the deterioration of the papiloperimetrics parameters. The therapeutic approach consisted of additional medication, filtration revision, subsequent surgical treatment physical end/or classic. The authors suggest a sequence for the operated cases of POAG, but that continued to progress, postoperative IOP "seemingly normal" requiring the follow-up for t e disease, in spite of using entire methods of the treatment.

[Particular aspects of treatment in diabetic eye cataract].

The knowing of the ocular consequences of diabetes is essential for the evaluation of the risk factors for the cataract surgery. The clinical study was made on a total number of 19 diabetic patients (3 with insulin dependent diabetes and the rest with noninsulin dependent diabetes), which were operated for cataract from september 2001 till march 2002. Preoperatory preparation presumed a good metabolic control of diabetes and a very carefully examination of the retina. The surgical technique was the extracapsular cataract extraction, followed by the implantation of a posterior chamber IOL, respectively phacoemulsification with the implantation of a foldable lens. The presence of a proliferative diabetic retinopathy, of a rubeosis iridis, of the neovascularization of the angle, or the preexistence of the vitreoretinal surgery (vitrectomy) were the main factors which dictated the anatomical and functional postoperatory prognosis. In conclusion, evenly the diabetic patient is a highly risk patient, the adequate preoperator preparation, the right treatment and a carefully follow-up could assure the success of the surgery in those cases.
