[The causes of childhood blindness and visual impairment in Poland].

AIM: To investigate the prevalence and the causes of childhood blindness and visual impairment in Poland. MATERIAL AND METHODS: The records of 3000 visually impaired children from the archives of Polish Association of Blinds and from the centers and schools for visually handicapped children from the years 1979-1999 have been reviewed. RESULTS: The number of the visually disabled children in Poland has increased by 70% in the recent 10 years. The main causes of blindness and serious visual loss in the years 1979-1999 are optic nerve atrophy (21.66%), retinopathy of prematurity (19.01%), cataracts (14.13%), high myopia (11.84%), congenital abnormalities (8.65%), retinal dystrophies (8.08%) and glaucoma (6.42%). Optic nerve atrophy occurred mainly in premature infants. There have been great changes in the epidemiology of blindness in the recent 20 years; the percentage of visually disabled children caused by ROP has increased from 8.1% to 54.5% and caused by optic nerve atrophy from 15.5% to 27.27%. The prevalence of other causes has decreased in the same time. CONCLUSION: The main activities required to control blindness in Poland are promotion of pregnancy and prematurity care and improvements in the early diagnosis and treatment of retinopathy of prematurity.

[Full-sclera resection in treatment of retinopathy of prematurity stage 4b].

AIM OF THE PAPER: The prognosis for vision in children with ROP stage 4b is extremely poor and our traditional methods of treatment of retinal detachment are usually ineffective because of marked retinal shortening. Therefore, in the paper a new method of surgical treatment of retinal detachment in stage 4b based on 180 degrees full-sclera resection is presented. MATERIAL AND METHODS: 14 patients with ROP stage 4b were treated with the use of 180 degrees full-sclera resection. RESULTS: Retinal reattachment was obtained in 86% of operated patients. Visual acuity of 0.1 was found after the operation in 57% and 0.08-0.02 in 43% of these children. CONCLUSIONS: 180 degrees full-sclera resection can be recommended as an effective method of treatment of ROP stage 4b in selected patients who meet the inclusion criteria.

[Functional results in children with retinopathy of prematurity stage 4 and 5].

AIM OF THE PAPER: To investigate the structural and functional results in children with retinopathy of prematurity stage 4 and 5. MATERIAL AND METHODS: 91 children with ROP stage 4 and 5 were observed by the authors in years 1990-1998. In all patients the clinical course of the disease, visual acuity and binocular vision were examined during follow-up. RESULTS: Most patients with ROP stage 4 and 5 are blind or practically blind, even the children in whom only stage 4a was diagnosed. CONCLUSION: Prognosis for vision in children with ROP stage 4 and 5 is poor and all methods of surgical treatment of retinal detachment should be performed in these children to safeguard some kind of useful vision in some patients.

[Nomenclature problems in glaucoma].

UNLABELLED: To present suggestions concerning the nomenclature of different types of primary glaucoma. METHODS AND RESULTS: The new nomenclature of primary glaucoma was proposed basing on the pathogenesis of the disease and semantic functions of different definitions.

[Use of cyclophotocoagulation with diode laser in treatment of secondary glaucoma in children].

AIM OF THE PAPER: To evaluate the effectiveness of transscleral diode laser cyclophotocoagulation in treatment of secondary glaucoma in children. MATERIAL AND METHODS: 50 children (50 eyes) with secondary glaucoma (aphakic, posttraumatic, in Sturge-Weber syndrome and in aniridia) which was uncontrolled with medical and surgical therapy or the surgery had a high risk of postoperative complications. In all patients diode laser transscleral cyclophotocoagulation has been performed. RESULTS: After one month intraocular pressure was reduced (with or without medical treatment) below 23 mm Hg in 40% of patients and after 6 months in 68% of patients. The worst results were observed in posttraumatic glaucoma. CONCLUSION: Diode laser transscleral cyclophotocoagulation is a safe and effective method of secondary glaucoma therapy in children uncontrolled with other methods of medical and surgical therapy or when the surgery has a high risk of postoperative complications.

[Treating retinopathy of prematurity with laser diode photocoagulation].

AIM: The purpose of the study was to assess the outcomes of the diode laser in the treatment of retinopathy of prematurity and to discuss the up-to-date possibilities of treating of active phase of this disease. MATERIAL AND METHODS: 96 children (185 eyes) treated with diode laser retinal photocoagulation for active stage 3 of ROP in our department in years 1996-2000. RESULTS: Favorable structural outcome was observed in 83.8% of treated eyes. In the remaining eyes the disease progressed despite of the treatment and falciform retinal fold (5.4%), partial retinal detachment (6.5%) and total retinal detachment (4.3%) developed. No serious complications were observed after the treatment. CONCLUSIONS: Diode laser retinal photocoagulation is a safe and effective procedure for treating active stage 3 of retinopathy of prematurity. It has been especially useful for treatment of changes in zone 1 and 2 of the disease. Diode laser photocoagulation is now the preferred method of treating active stage 3 of ROP in our department.

[Possibilities of diagnosis and treatment of eye disease by general practitioners].

PURPOSE: To analyse possibilities of diagnosis and treatment of eye diseases by practitioner. MATERIAL AND METHODS: The number and diagnosis profile of patients treated in average municipal out-patient ward was calculated and possibilities of their treatment by general practitioner were analysed. RESULTS: In 87.4% of eye-patients general practitioner cannot diagnose and treat the disease and he has to send them to an eye-doctor. CONCLUSION: The system that eye-patient cannot check-in directly to an eye-doctor is more costly because general practitioners can diagnose and treat only small number of these patients. Therefore nearly every patient has to be consulted be eye-specialist, which increases the costs of treatment because patient has to be seen by two doctors.

[Clinical manifestations and treatment of Terson's syndrome].

AIM OF THE STUDY: To present clinical manifestations of Terson's syndrome and the results of treatment of vitreous hemorrhages with the use of intravitreous injections of anti-Rh serum. MATERIAL: 8 patients with disc, retinal, vitreous hemorrhages and abducens paralysis which developed after subarachnoid hemorrhages. Intravitreous hemorrhages were observed in 4 of those patients. RESULTS: Vitreous hemorrhages cleared spontaneously in two patients. In the remaining two ones with no tendency for blood resorption intravitreous injections of anti-Rh serum were performed. Vitreous hemorrhage cleared in all the patients after 5-6 weeks and visual acuity improved to 0.8. CONCLUSION: Intravitreous injections of anti-Rh serum can be the method of choice in the treatment of vitreous hemorrhages in Terson's syndrome with no tendency for spontaneous resorption and without proliferative vitreoretinopathy.

Retinal cotton-wool spots as the first sign of systemic sarcoidosis.

Isolated retinal cotton-spots have not yet been reported as the sign of ocular sarcoidosis. We describe three patients with retinal cotton-wool spots of initially unknown etiology in whom systemic sarcoidosis was diagnosed 6-16 months later. The diagnosis was confirmed by conjunctival biopsy. These observations indicate that sarcoidosis should be included in the differential diagnosis of retinal cotton-wool spots and patients with these lesions should be followed for the development of this disease.
