[Trabeculectomy as the initial procedure in primary congenital glaucoma].

PURPOSE: To estimate the effectiveness of trabeculectomy performed in buphthalmic eyes. MATERIAL AND METHODS: 42 eyes of 24 children, 14 boys and 10 girls. There were 18 children (32 eyes) operated on at the age from 7 days to 12 months (group I) and 6 patients (10 eyes) at the age from 3 to 7 years (group II) with primary congenital glaucoma. Corneal diameter ranged from 11.5 to 15 mm in infants, in 10 eyes of 6 children elder than 2 years it was from 13 to 15 mm. The axial length of eyeballs was from 19 to 23.5 mm. Forty five trabeculectomies were performed, in 3 cases they were repeated two and six years after the first procedure. Follow up was from 1 year to 22 years, mean 82 months, 7 years of group I, 6 years of group II. RESULTS: 29 of 42 eyes (64.2%) with intraocular pressure varied between 8 and 21 mm Hg, other eyes required additional local antiglaucoma treatment. Normal IOP was obtained in 95.2% of eyes. Trabeculectomy normalized IOP in 68.9% eyes of infants (group I), whereas in elder children the percentage came up to 50 (group II). In other eyes pharmacological agents decreased IOL to values below 21 mm Hg, in the group I in 97% of eyes and in the group II in 90% of cases. CONCLUSION: Trabeculectomy performed as a first procedure in primary congenital glaucoma is effective in infants and older children with buphthalmos in long-term follow-up. The necessity to perform this operation in very small children and even neonates does not always mean poor prognosis, and intraocular pressure can be stabilized at safe level for many years.

[Intraocular correction of aphakia after cataract extraction for uveitis in adolescents].

PURPOSE: To demonstrate 3 cases with pediatric pseudophakia after cataract extraction as a complication of unilateral uveitis. MATERIAL AND METHODS: The boys were at the age of 8, 11 and 15 years at the moment of surgery. Uveitis was monocular, the etiology unknown and clinically significant cataract was diagnosed after several months from the beginning of inflammation. The last recurrence of uveitis was observed 1 to 6 months before operation. There were intermediate uveitis (2 cases) and anterior uveitis (1 cases). In 2 eyes PMMA implant was placed in-the-bag and in one eye in the ciliary sulcus. During surgery we did not observe any complications except greater tendency to bleeding. Follow-up after operation ranged from 1.5 to 2.5 years. RESULTS: Visual acuity before cataract extraction was 0.01; 0.04 and 0.02 and during last visit after surgery it was 0.9, 0.6 and 0.4 respectively. Postoperative near distance visual acuity was 0.5, 0.75 and 1.25. We observed cystoid macular oedema in the latter case. Two months after PC-IOL implantation the symptoms of mild inflammation in the eye of 15-year-old boy with anterior uveitis occurred. Intraocular pressure before and after operation ranged from 12 to 17 mm Hg. Corneal central endothelial cell density was from 2850/mm2 to 3100/mm2 before and from 2469/mm2 to 2979/mm2 during last visit. CONCLUSION: Cases of posterior pseudophakia during uveitis in children showing good functional and anatomical state of eyes in the long term observation after IOL implantation recommend the intraocular correction in carefully selected uveitic pediatric patients.

[Therapeutic contact lenses in infant corneal ulcerations].

PURPOSE: We present our own results of treatment in corneal ulcerations with therapeutic contact lenses in 4 infants aged between 3 days to 5 weeks. MATERIAL AND METHODS: Four patients (5 eyes) with deep corneal ulcerations of various origin were treated with soft contact lenses at the Clinic of Pediatric Ophthalmology in Katowice. All eyes received one type of the therapeutic lens. Contact lenses were worn between 8 and 21 days. After application of contact lenses pharmacological therapy was used individually for each patient, according to the result of microbiological tests. RESULTS: All patients were successfully cured. A scar of cornea was observed only in one infant because the contact lens had been used too late. Four infants had no corneal haze after the treatment. CONCLUSION: The best results were obtained using the contact lenses early, during the first days of treatment. Contact lenses caused decreasing of pain and reduced application of medicines. They were a good protection for injured cornea.

[Scanning laser tomography in the diagnosis of juvenile glaucoma].

The aim of our research was to evaluate the optic nerve head parameters of children with juvenile glaucoma with the scanning laser ophthalmoscope from Laser Diagnostic Technologies Inc. The material consisted of 46 eyes of 25 children aged from 7 to 18 years. There were 18 glaucomatous eyes (I group) and 28 eyes without glaucoma (II group) as a control group. The three examinations were repeated every three months. Mean values of Vol. B in the glaucomatous group were -0.327 +/- 0.098, first visit; -0.390 +/- 0.130, second visit; 0.344 +/- 0.096 mm3, third visit. These values in the control group were--0.234 +/- 0.73; -0.224 +/- 0.071; -0.252 +/- 0.069 mm3. The difference was statistically significant. Mean values of Volume A were significantly lower in the I group: 0.216 +/- 0.034, 0.207 +/- 0.033, 0.203 +/- 0.030 mm3 than in the II group: 0.269 +/- 0.039, 0.283 +/- 0.032, 0.271 +/- 0.042 mm3. CD ratio was higher in the glaucomatous eyes: 0.447 +/- 0.080; 0.491 +/- 0.069; 0.484 +/- 0.074 in comparison with the control group: 0.376 +/- 0.060; 0.368 +/- 0.067; 0.399 +/- 0.056. It was significant difference. More changes of biomorphometric parameters of the optic nerve head were observed in the glaucomatous group during follow-up period. The role of laser scanning ophthalmoscopic tomography is very important in the diagnosis of early forms of juvenile glaucoma in the youth.

[Cataract in uveitis in children].

PURPOSE: To evaluate the anatomical and functional state of eyeballs after cataract extraction in uveitis in children and to analyze the factors affecting visual outcome. MATERIAL AND METHODS: Among 182 examined eyes with uveitis we have observed cataract in 22 eyeballs of 17 children (12%). Before operation in 72.7% cases visual acuity was less or equal 0.02, in the others it was not more than 0.2. The age of patients ranged between 2 and 18 years, the mean age 8 years. The cause of uveitis was: chronic tonsillitis or sinusitis in 6 patients, juvenile rheumatoid arthritis in 2 patients, heterochromic Fuchs iridocyclitis in 2 children, in the others the cause was unknown. In 4 eyeballs (18%) we have observed increased intraocular pressure before operation. Follow-up ranged from 6 months to 15 years, the mean was 5 years. RESULTS: We have obtained normal visual acuity in 31.8% cases and better than 0.1 in 68.2% od eyes. In children with juvenile rheumatoid arthritis, 2 eyeballs lost light perception as a result of corpus vitreous fibrosis and in one case we have observed only light perception. Optic nerve glaucomatous neuropathy was the cause of poor functional result in 2 eyes (0.02 and 0.04). Another causes of not satisfactory visual acuity were: corneal dystrophy (2 eyes), cystoid macular oedema (2 eyes) and amblyopia ex anopsia (2 eyes). CONCLUSIONS: We have obtained normal or good visual acuity in majority of the operated eyes. The causes of poor vision were the anatomical changes after uveitis before the cataract extraction.

[The significance of myopia and birth weight in prematurity].

AIM: The relation between myopia and birth weight of premature newborns was assessed in this study. MATERIAL AND METHODS: There were 90 children (180 eyes) involved in the study, their birth weight ranged between 580 and 2450 g (mean 1698), and myopia ranged from -1.5 to -22.5 D (mean -9.8 D). Children were divided into two groups: group I: 38 children (76 eyes) with birth weight from 580 to 1500 g (mean 1158 g), group II: 52 children (104 eyes) with birth weight from 1501 to 2450 g (mean 2093 g). Mean value of myopia in group I was -10.4 D and -9.4 D in group II. RESULTS: The results were assessed with Statgraphics software. The analysis of mean values regression showed no relation between myopia and birth weight in group I (regression coefficient b = 0.003, p = 0.24) and no relation in group II (regression coefficient b = 0.008, p = 0.016) at significance level alpha = 0.01.

[The computer as an assistant to the physician].

BACKGROUND: The possibilities of using computer in physician's research work are presented as an example of statistical analysis of axial eyeball length in relation to the age in myopic children with low birthweight. MATERIAL AND METHODS: The study group consisted of 100 children aged from 3 to 15 years, with birthweight from 580 to 2450 g, where in 180 eyes myopia ranging from -1.5 to -22.0 Dsph and axial length of the eye from 20.0 to 30.9 mm were present. The dynamics of eyeball's axial length increase was compared between two groups: one-in which no symptoms of retinopathy of prematurity were present (no-RROP), and the second--in which signs of regressed retinopathy of prematurity were observed (RROP). RESULTS: The results of the analysis are shown in analytical and graphical modes. Statistically significant differences were shown between axial lengths of eyeball's in the analysed groups of mean 9-year-old premature children (no-RROP: 25.19 mm and RROP: 24.33 mm). It was shown that the use of a computer reduces the time of performing statistical analysis of large amount of data.

[Laser scanning laser ophthalmoscopy in diagnosis of juvenile glaucoma cases with myopia].

UNLABELLED: The diagnosis of the open angle glaucoma in myopic eyes remains one of the major problems, as the changes of the optic head in myopia may be similar to glaucomatous changes. The aim of the study was to analyse biomorphometric parameters of the optic nerve head in myopic eyes with glaucoma with scanning laser ophthalmoscope from Laser Diagnostic Technologies Inc. There was 29 children examined and among them 12 children with glaucoma and myopia as a study group (I) and 17 children with myopia as a control group (II). RESULTS: TCA means values; group I: 1.994 +/- 0.158, group II:2.028 +/- 0.200 CD means values; group I; 0.315 +/- 0.072, group II: 0.247 +/- 0.057 Rim means values; group I: 1.366 +/- 0.164, group II: 1.511 +/- 0.136 Vol. A mean values; group I: +0.205 +/- 0.03, group II: +0.83 +/- 0.03 Vol. B mean values; group I: -0.159 +/- 1.608, group II: -0.117 +/- 0.08. Average values of the biomorphometric parameters of the optic nerve head were worse in group I than in group II, but there was not statistical significance between the differences. Scanning laser ophthalmoscopy may be used as very important additional examination in juvenile glaucoma cases with myopia.

[Eyeball axis changes in children's myopia].

The aim of study was to assess changes in eyeball axial length in myopic children depending on age in comparison with hyperopic and emmetropic groups. The study group consisted of 200 children (100 girls and 100 boys), from 3 to 17 years old (mean 9.8). Myopia was diagnosed in 376 eyes (-4.0 D to -24.0 D, mean -9.64 D) with axial length from 21.0 to 30.95 mm (mean 26.05 mm). Control group consisted of 334 eyes (167 children) with mean refraction +0.53 D and axial length from 20.0 to 23.9 mm (mean 22.36 mm). We have used the Statgraphics program for statistical analysis. A statistically significant difference was found between mean eyeball axial length within myopic group of girls (mean 25.77 mm) and boys (mean 26.31 mm) with p = 0.321 and significance level alpha = 0.05. The axial length increases irregularly over time. The axis of the eyeball in myopic children aged between 3 and 17 increases more than in emmetropic and hyperopic (up to 1.0 D) children.

[Optic neuritis in children and adolescents].

The aim of the study was to analyse the cause, course and results of treatment in cases of optic nerve inflammation, including frequency of recurrencies. One hundred and ten children aged 2-18 years treated in our clinic from 1989 to 1994 were examined. Mean age was 13 years. Bilateral inflammation was found in 60% of cases, 176 eyes were assessed. The disease was more frequent in autumn, winter. In children below 14 (62%) inflammation concerned the intraocular part of the nerve while in older children it was mainly retrobulbar. Recurrence of the disease was observed in 1/3 of cases. In younger patients, the cause of the inflammation was usually viral infectious disease or chronic focal infection. In older children, the main causes were trauma or underlying neurological diseases. The treatment administered resulted in a normalisation of the visual field in more than half of the cases and visual acuity improvement in 73.5% of cases after retrobulbar inflammation, and in 75% of cases after intra-bulbar inflammation. During an average follow-up of 3 years, full visual acuity was achieved in 56% of eyes after retrobulbar inflammation and 46% of eyes after intra-bulbar inflammation. Signs of post-inflammatory neuropathy were present in 46% of eyes. Full recovery of visual function was achieved especially in those cases where it was not deeply decreased during the disease.

[Diagnostic and therapeutic problems of juvenile glaucoma].

The material comprised 27 patients, aged 6-15 years, treated for juvenile glaucoma. Non-typical first symptoms, good visual acuity in the majority of the cases, the lack of anatomical changes of anterior segment of the eye and the elongation of the anatomic axis, difficulties in the evaluation of optic disc changes, especially in myopic eyes, and the lack of correlation of these changes with the results of visual field examination, little reliable in children, and also very often the normal intraocular pressure values, delay the diagnosis and make it much more difficult. The repetition of tests and the indication of the C factor make the diagnosis much easier. During the follow-up, intraocular pressure was well-controlled in 87% of the cases, 10% of them with additional optic treatment.

[Glaucoma after congenital cataract extraction in children].

The clinical material comprised 45 eyes in 33 children aged from 5 months to 8 years. In the period of 5 days to 7 years after congenital cataract surgery, an increased intraocular pressure has been observed. Antiinflammatory treatment, optic, cyclocryotherapy, synechia-lysis, anterior vitrectomy, YAG-laser and trabeculectomy were applied, depending on the mechanisms that caused the increase of intraocular pressure. In 1-5 years follow-up, the control of intraocular pressure, using the pharmacological treatment and/or surgery, was obtained in 88.4% of the cases. On admission, the enlargement of the eyeball was observed in 26.6% of children, whereas in every fifth of them the cupping of the optic disc was recorded.

[Retinopathy of prematurity and retinal detachment].

The authors examined 60 children (91 eyes), aged 5 months to 17 years, with retinal detachment in the ROP course; 19 eyes were selected for the surgery, 5 eyes with the active ROP phase and 14 myopic eyes with the vitreo-retinal changes resulting from ROP. The segmental or encircling scleral buckling was performed in 19 eyes, in 4 eyes the vitrectomy and the endo-tamponade was used. In 12 eyes (63%) the retinal attachment was achieved, in 2 eyes in the active phase (40%) and 10 eyes (71.3%) with regressed ROP.

[Eye burns in children and adolescents].

The authors present a material of 91 eyes in 66 children aged 2 days to 16 years, who sustained burns of the eyes. Fifty one eyes (1st group) was burned by thermal or chemical means, mainly by lime; 40 eyes (2d group) sustained chemico-mechanical injuries caused by explosions of petards or miner's detonators. Bilaterality of the injuries was seen in 50 p.c. of cases of the 1st group and in 25 p.c. of cases of the second group. Reduction of the visual acuity down to light perception was observed in 19.7 p.c. of cases of the 1st group and in 22.5 p.c. of cases in the 2d one; at the same time 2 cases of this group became blind. The cause of deterioration of the visual acuity in the group of chemico-thermal trauma were the corneal opacities, in the group of mixed injuries--changes in the posterior segment of the eye.

[The role of ocular symptoms in the diagnosis of neoplasms of the central nervous system].

Eighty four patients with a diagnosis of a neoplasm of the central nervous system were examined; full ophthalmological examination was performed in all of them. They showed pathological signs in the ocular adnexa, abnormal positioning and motility of the eyes, nystagmus, poor visual acuity, defects of the visual field, pathological changes in the anterior and posterior segment of the eye. In general--abnormal signs in the visual system were seen in 84.5 p.c. of cases comprising all of the children. In a part of cases ocular signs and symptoms were the only ones which drew attention from the side of the patient.

[Phaco-aspiration and phaco-emulsification of cataract--personal experience].

The authors present material collected in the course of 10 years of applying the surgical technique of cataract extraction by means of a Cavitron-Kelman model 8000 V. The age of the patients oscillated between 4 months and 80 years. Phacoaspiration was performed in 4416 eyes and phacoemulsification in 2195 eyes. Following intraoperative complications were observed during surgery; rupture of the posterior lens capsule occurred in 9.75 p.c. of eyes in the course of the phacoaspiration and in 12.4 p.c. of phacoemulsification. The endothelial corneal degeneration occurred after phacoaspiration in 0.13 p.c., after phacoemulsification in 3 p.c. of cases; cystic macular oedema after phacoemulsification in 0.95 p.c. of cases. Visual acuity 5/25 to 5/10 was attained in 47.1 p.c. and visual acuity of 5/10-5/5 in 37.3 p.c. of the eyes. A larger number of complications after phacoemulsification--in spite of the time of application of the ultrasound considered as a safe one--caused a reduction in application of this method.
