The paper attempt a NPG definition in the light of the most recently data from literature. Modern investigation techniques (CDI, LDF, laser scan angiography) are summarized to support the presently most accepted pathogenic theory--the vascular theory. There are also reviewed the main clinical conditions to do differential diagnosis and main methods of its treatment.
The authors study the consequences of the ocular traumatisms hospitalised and treated in the Department from the Central Military Hospital in Bucharest, on a group of 1144 patients. This group represent 7.84% from a total of 14,641 patients hospitalised in that period of time. There are also included the patients who suffered ocular traumatisms during the revolution in December 1989.
Pseudophakia generates a new pathology, sometimes atypically solved, insufficiently codified yet. The paper presents the experience on quite a large group of cataract-operated patients with implantation of pseudofac, in which cases of ocular hypertonia appeared.
The paper reports on the author's own experience in the surgical treatment of the traumatic cataract in children. The authors consider that implantation of the artificial crystalline must not be a general implantation method, in any eye. It has to be made discriminatingly and take into consideration the posttraumatic inflammatory reactions and the local state of each eye.
The theoretical part of this paper presents the mechanism of the IOP lowering effect using these drugs, the indications of treatment and the main side effects. The second part consist of the experimental study made on rabbits, using the izopropilic ester of (+)Cloprostenol as an hypotensive agent. We have registered the IOP values and the main side effect--conjunctival hyperemia. The third part consist of the clinical study, made on a test lot of 23 patients. We have used the same substance and in the experimental study, as a unique treatment or in association with a beta-blocker or a pilocarpine derivative. The following-up has implied: the IOP, the ophthalmoscopic appearance of the optic disc, the visual field, the visual acuity and the main side effects. In the end, we have formulated the conclusions of these studies.
Pneumatic retinopexy has been recently reported as an alternative procedure in the treatment of retinal detachments. This technique may be considered if the break is no larger than the 1 o'clock hour, the break is located superiorly between 8 o'clock and 4 o'clock and there is no proliferative vitreoretinopathy greater than C1. The expandable gas SF6 (sulphur hexafluoride) has been used in the treatment of 16 cases of retinal detachment. Two of them were new cases treated with pneumatic retinopexy and cryotherapy applications and they were both successful. The other 14 cases were redetachments, so the treatment was completed by scleral buckling in 9 cases and scleral buckling with permanent implants of silicon in 5 cases. The rate of success was 3 to 9 and 2 to 5. For the rest of 9 cases vitrectomy or silicon oil injection would have been useful. Pneumatic retinopexy proved to be a low-price surgical treatment easy to use even in a consulting room, in one or two-session method. It may be performed as a single procedure for new cases of superior retinal detachments or in addition to other surgical techniques on selected cases.
The paper presents a synthesis of today's means for differential diagnosis between symptomatic and idiopathic retinal detachment, considering that the retinal detachment remains an ocular emergency, with high invalidity potential. The characteristic difficulties of this diagnosis are also detailed. The different medical attendance of the two types of retinal detachment requires a rigorous differential diagnosis, according the leading part to the ophthalmological examination. There are also illustrated up-to-date diagnosis tests, less invasive and more informative, such as: CT and MRI. The survey highlights the value still relative of the majority of these investigations and the fundamental significance of the histological examination.
The paper presents the statistical study of the appearance of explantation on the whole of artificial lenses implants, at the Ophthalmology Service of the Central Military Hospital during the years 1989-1993. The statistics relies on the review of data extracted from the operation registers, elaborated during the mentioned period, followed by their computerized processing and plotting. The authors also referred to the types of postoperative complications and their weight in the genesis of the explanation, as well as their distribution related to the sort of implanted intraocular lens. The survey also illustrates the long-run evolution of the reimplantation percentage. The results are comparatively reviewed to those in the specialty literature.
The paper presents a short history of the cataract intervention, starting from the lens luxation in vitreum and going to the implant of artificial lens. From the three classes of artificial lenses, up-to-date options are the posterior chamber artificial lenses. Today, in 80% of the cases, artificial lens implant is done, 80% of the implanted lenses being posterior chamber lenses. The paper also exposes various operatorial techniques, post-operatorial evolution and the results obtained.
