The observations concerning the treatment of 5 patients suffering from the serous macular detachment caused by the optic pit are presented. In all 5 cases, the laser photocoagulation along the temporal margin of disc was applied. The retinal attachment was obtained in 2 eyes.

Among 600 operated retinal detachments in the last 5 years (1985-1989) there was no tight closure of the retinal hole after operation in 78. The causes were: the implant situated paracentrally to the hole, lack of contact between the implant and the hole, an insufficient scar, additional hole. Various types of the performed surgery were analyzed: the meridional or parallel implant, the balloon and endotamponade with the SF6 gas, executed with and without drainage of the subretinal fluid. In cases in which in the postoperative course was detected a lack of tightness of the hole the laser photocoagulation was performed in the area of the flat retinal detachment on the implant in a couple of stages. A favourable result of photocoagulation was attained in 75 patients (96.2 p.c.); in the remaining 3 patients (3.8 p.c.) a second surgical procedure was performed.
Analysed were the results of surgical treatment, causes of the failure and early recurrence in 108 patients with retinal detachment in whom was performed an indentation of the sclera by means of a balloon (1st group--50) or by an episcleral implant (2d group--58). In the first group the apposition was achieved in 92 p.c., in the 2d group in 90 p.c. An early recurrence (2 weeks to 2 months) was observed in 9 eyes which were operated again achieving an apposition of the retina in 6 eyes. There were following causes of the failure: the existence of a second hole, rupture of the balloon, PVR before surgery and traction of the retina in the region of the hole. An early recurrence occurred in the consequence of intensification of the PVR together with inaccurate localization of the implant, existence of the PVR before the operation and traction of the retina in the vicinity of the hole, formation of a new hole.
In the period of 1983-1988 among 57 retinal detachments in children and youth in 8 cases (10 eyes) the authors found the retinopathy of prematurity as a cause of retinal detachment. The characteristic picture of changes in these eyes was discussed. Combined surgical procedures were performed in 7 cases achieving a cure in 6. Emphasized was the significance of periodical examinations of these eyes with the aim of eventual prophylaxis of retinal detachment and of therapy of amblyopia.
The authors presented methods and results of treatment by means of an argon laser of 12 patients with pathological changes of the retinal vessels. Diagnosed in these patients were: capillary haemangioma (Hippel-Lindau disease), teleangiectasis and macroaneurysms of the retinal vessels. Photocoagulation by argon laser of these vascular changes in these patients in right time showed to be a favourable therapeutic method, especially when the changes are localized in the posterior pole of the eye.
The authors examined 78 fellow eyes in patients aged 2.5-20 years treated for retinal detachment. The examinations were carried out in the course of the hospital treatment and 2-10 years after the discharge from the Ophthalmological Department. In the period of observation the progression of the vitreous changes was seen in 9 eyes and it took the form of appearance or increase of the fibrillar degeneration of the vitreous, the condensation of its basis and of vitreoretinal adhesions; it coexisted with the appearance of new pathological processes in the retina. During the hospital treatment the retinal pathological changes were seen in 30.8 p.c. of cases and in the late examinations in 41 p.c. The most frequently discovered degeneration was the lattice degeneration. The frequency of the fellow eye syndrome in the late examinations increased from 10.2 p.c. to 17.7 p.c. of the examined patients.
PURPOSE: Presentation of the cases with a rare form of persistent hyperplastic primary vitreous. MATERIAL AND METHODS: 5 children, aged 3-14, were referred to the clinic with suspicion of neoplasm changes or congenital anomalies of the eyeball. Unilateral, pathological lesions, in the form of opaque membranes, partially or totally covered the optic disc, were found. In 2 cases persistent fragments of arteria hyaloidea were also observed. Diagnosis was mode basing on three mirror glass examination, ultrasonography and fluorescein angiography. In differential diagnosis, retinoblastoma and other entities determined in the literature as pseudo-retinoblastoma were taken into account. The children remained under clinical follow-up.
