Triple procedure 'a chaud'.

Although it is widely accepted that acute uveitis is the main contraindication for intrabulbar procedures, conditions in the presented group of 24 patients (mean age 63 years, ranging from 35 to 74) required immediate surgery. The corneal pathologies included: perforated corneal ulcer in 12, imminent corneal perforation in ten and corneal melting syndrome in two patients. Partial perforative keratoplasty was accompanied by various combinations of surgical procedures, depending on the preoperative status. In cases of aphakia (N = 5) and anterior chamber pseudophakia (N = 5) secondary PCIOL implantation with sulcus fixation was performed, combined with ACIOL explanation in the latter group. The largest group included patients with complicated cataract (N = 14), where classic triple procedure was performed in ten patients. In three patients, the surgery had to be completed with sulcus fixation of the PCIOL, due to posterior capsule rupture. Associated glaucoma in one patient required trabeculectomy along with triple procedure. Postoperative complications that could not be treated with conservative measures for subsequent corneal decompensation, required rekeratoplasty in three (12.5%) patients. Visual acuity amelioration, ranging from 0.2-0.8, was achieved in seven (29.2%) and nine (37.5%) patients after 3 and 6 months, respectively.

Timing of cataract surgery in diabetics.

In their retrospective study, the authors investigated the outcome of extracapsular cataract extraction (ECCE) followed by posterior chamber intraocular lens implantation (PCIOL), in 2864 operated eyes, out of which 546 (19%) were in diabetics. The preoperative retinal status was recorded in all subjects. In 6 (1%) patients, laser photocoagulation was performed preoperatively. The obtained visual acuity was 0.4 or better in 90.0% of diabetics and in 91.8% of control subjects, showing no significant difference in the postoperative complications between diabetics and non-diabetics. The results indicated the cataract operation (ECCE + PCIOL) to be a well tolerated surgical procedure in diabetic patients with lenticular opacity, in whom it should be even earlier performed than in nondiabetics, because cataract prevents the diagnosis or treatment of a suspect retinal disorder.

A brief review of the development of ophthalmology in Croatia.

Autochtonous folk medicine practice in Croatia was mostly based on the use of herbs in the treatment of eye diseases. The first document on the presence of medical activity was one in which the Republic of Venice gave Draga Slava permission to practice medicine in 1330. The 19th century was the turning-point for the development of ophthalmology in Croatia. The basis for well-organized clinical, preventive and social ophthalmological care was established. The Cathedra for Ophthalmology was founded in 1920 and its first head was Albert Botteri, who was along with Nizetić, Spanić, Gradilicić and Meixner, the most prominent ophthalmologist in the first half of the century. Zvonimir Pavisić and Kresimir Cupak were the leading persons in Croatian ophthalmology in the second half of the century. Croatian ophthalmologists were organized in the Section for Ophthalmology as the part of the Medical Association of Croatia from 1926 up to 1992, when the Section changed its name to the Croatian Ophthalmological Society, with more than 250 members. Inspite of the difficulties, Croatian ophthalmologists tend to use almost all modern diagnostic and therapeutic methods in use in the world.

Risks of retrobulbar application of anesthetics and drugs.

In spite of hundreds of harmless retrobulbar applications of anesthetics and drugs, a certain risk still exists. In the past ten years in our Department with 7200 retrobulbar procedures performed in local anesthesia and 12500 retrobulbar applications of the drugs (corticosteroids, antibiotics, vasodilatators) 14 incidents were registered. Palpebral chemosis and retrobulbar hematoma or eyeball protrusion were transient in 11 patients. Acute disturbance of the chorioretinal circulation occurred in three patients. In one of them vascular occlusion was total with permanent loss of vision, while in the other two recuperation of vision was the sign that vascular spasm was transient.

Postnucleation orbital implants.

A follow-up study of a group of 40 patients after the enucleation completed by the intra-orbital acrylic spherical magnetic implant (Roper-Hall style) is presented. The mean postoperative observation time is 3.3 years. Late complications were present in two patients: the extrusion of the implant in one of them was probably caused by his poor state due to chronic dialysis, while the traumatic luxation of the implant in the other was surgically repaired. Postoperative results in all other patients were satisfactory with the adequate orbital volume substitution and the ability of the prosthesis to twist and turn in any axis without fitting problems.

[Comparative analysis of the results after implantation of a "one piece" and other types of intraocular lenses].

The authors analysed the results obtained in 100 patients with the "one piece" posterior chamber lens and compared them with those in 85 patients with soft haptics. All procedures followed the extracapsular cataract extraction. The incidence of intraoperative and postoperative complications was compared. Special attention was paid to the positioning of the implant after a period of at least 6 months. The advantages of "one piece" implant lenses were established and better postoperative results obtained in this group of patients.

The importance of computer observation of postoperative complications in ophthalmology presented on the model of postoperative complications following cataract surgery.

Medical documentation is getting more extensive, it is not standardised and can hardly be used to provide the exact and proper feedback. The crisis of data storage, processing and uninterrupted flow of information is becoming concial in the medical institutions as well. An example of informatic model of observation of postoperative complications following cataract surgery is presented in this work. The model has a very flexible pattern, and can, therefore, with minor changes, be used in observation of all postoperative complications in ophthalmology. It is based on the use of personal computer with professional software support (data base III programme was used for creation of data base, while statistical graphic analysis was carried out by following programmes: MICROSTAT, ABSTAT, STATGRAPHIC and FRAMEWORK). It has to be pointed out that any doctor, after only a short (optional) education, could prepare such models for his own purposes, and could thus assist in overcoming the information in medicine. In conclusion, the authors state computer is simple to work with, fast, economical and precise. Computerisation of health service shall include it in one of the aspects of practical realisation of the third technological revolution.

Cataract surgery and uveitis.

The authors deal with uveitis and cataract from two aspects. The occurrence of uveitis was analysed both before cataract surgery and postoperatively. The authors found in their material that uveitis occurred before cataract surgery in 1.8% and postoperative uveitis in 1.2% of cases. Special emphasis is put on the occurrence of postoperative complications in such eyes and the indications for the IOL implantation in uveitis patients.

[Implantation of intraocular lenses in patients with diabetes].

The authors analysed and compared three groups of patients who had undergone surgery. In the first group of 72 patients with diabetes and cataract, intraocular lens implantation was carried out. In the second group of 96 patients with diabetes and cataract, cataract surgery was not followed by intraocular lens implantation. The third group of 100 nondiabetic patients, selected by random choice, had intraocular lens implanted after the cataract surgery. Retinal status, postoperative complications and visual acuity were the parameters analysed in correlation with the intraocular lens implantation. In the authors' opinion, the prognosis following cataract surgery and intraocular lens implantation in diabetic patients is good, if diabetic complications do not occur, particularly retinopathy and vitreal hemorrhage which impair the vision considerably. Intraocular lens can be implanted even in cases of maculopathy and preproliferative diabetic retinopathy, provided a thorough diagnostic evaluation has been performed (echography, fluorescein angiography). Laser photocoagulation procedure should also be carried out before surgery and repeated as long as the transparence of the lens enables it. The treatment should be resumed two weeks after the cataract surgery and intraocular lens implantation at the latest. Intraocular lens implantation is contraindicated in proliferative diabetic retinopathy, and especially iridal rubeosis, as the risk of neovascular glaucoma development is considerable.

Complications following two methods of posterior chamber intraocular lens suturing.

The aim of this study is to compare complication rates in two different operative techniques applied for the secondary, posterior chamber intraocular lens (PCIOL) implantation with sulcus fixation. 179 eyes with partial or no posterior capsule support underwent surgery. Applied techniques were: transscleral fixation of the IOL by passing with the fixation needle through the sulcus from the inside (70 eyes) or from the outside (109 eyes) of the bulbus. The most frequent intraoperative complications were haemorrhages and vitreous prolaps with no significant difference between used techniques. In the 'from the inside' group, following late postoperative complications developed: astigmatism of > 4D (24%), cystoid macular oedema (20%), pupil distortion (14%), partial posterior capsule opacification (10%), suture exposure (10%), IOL decentration (8%) and hemophthalmus (3%). In the 'from the outside' group same complications showed a decreased rate: 17%, 16%, 8%, 8%, 9%, 5% and 1%, respectively. Other late complications like high intraocular pressure, synechiae and uveitis were adequately represented in both techniques. After 24 months follow-up, best corrected visual acuity > or = 0.8 was achieved in 48.5% of eyes when 'from the inside' and in 57.7% of eyes when 'from the outside' technique was used.

Prognostic value of visual evoked responses in childhood amblyopia.

We assessed the possible clinical utility of pattern reversal visual evoked potentials in predicting the success of pleoptic treatment. Thirty amblyopic children--16 strabismic, 11 anisometropic and three of refractive type (in all cases the amblyopia was monocular)--and ten children without amblyopia (control group) were examined by conventional psychometric methods. Visual evoked potentials (VEP) to pattern reversal stimulation were also recorded. The amblyopic group was treated with occlusion of the preferred eye for three to six months. Psychometric and VEP tests were repeated in 15 amblyopic children after the treatment. The pre-treatment VEP amplitude side-differences (between amblyopic and better fellow eye) were significant, with first positive wave, P1, being invariably lower on the amblyopic side. We correlated the side-differences in visual acuity with the corresponding side-differences in amplitude and latency of the P1 wave. In the former the correlation coefficient was r = 0.47 (p < 0.01), and in the latter r = 0.65 (p < 0.01). Latency was prolonged in the eyes with significantly reduced visual acuity in which the wave form was also typical for amblyopia. We then correlated the difference between pre- and post-treatment visual acuity of the amblyopic eye with the pre- and post-treatment difference in amplitude (correlation coeff. r-0.51 (p = 0.05)) and latency of the P1 wave (correlation coeff. r = 0.40 (p > 0.05)).(ABSTRACT TRUNCATED AT 250 WORDS)
