[Problems in surgical management of persistent hyperplastic primary vitreous in children].

PURPOSE: To evaluate the surgical techniques that allows safe, effective removal of lens and retrolenticular fibrotic membranes in eyes with PHPV in children. MATERIAL AND METHODS: A total of 31 children (18 boys and 13 girls) with PHPV and cataract in one eye were divided into 2 groups, according to treatment modality. High frequency ultrasonography were used to identify anatomic correlates in the eyes--before operation. Limbal cataract extraction combined with vitrectomy and removalof embryonic remnants was carried out in 17 eyes, and a posterior pars plana approach in 14 eyes. RESULTS: In group with anterior approach, the most serious complication was corneal decompensation, in the next group--retinal detachement. CONCLUSIONS: The anterior and the posterior surgical technique to remove cataract and tenacious retrolenticular membranes was effective but associated with high risk of intraoperative and postoperative complications. Although the surgical intervention is necessary to prevent progressive pathologic changes and to obtain the best possible visualresults in some cases.

[Lens dislocation in children].

Ectopia lentis in children continues to be a diagnostic and therapeutic challenge for ophthalmologists. It can occur in isolation, in association with other ocular disorders or as part of systemic disorder. Marfan's syndrom and homocystinuria are the most frequent cause of heritable ectopia lentis. The authors describe ocular findings and clinical symptoms diseases with ectopia lentis. Differential diagnostic and treatment methods are discussed.

[Bilateral optic nerve sheath meningioma (ONSM) --diagnostic and therapeutic problems].

The authors describe the case of bilateral optic nerve sheath meningioma /ONSM/ in 14 years old girl. When being hospitalized at the Neurology Clinic with paresis n.VII, the patient was examined by ophthalmologist. The diagnosis was made on the basis of clinical and characteristic changes revealed by USG, CT and MRI. The very first ophthalmologic examination confirmed a visual acuity 5/5 OD and hand movements OS, associated with papilloedema OD and edematous optic atrophy OS. The use of USG, CT and MRI revealed bilateral tubular thickening of the optic nerves (8mm), with calcification. After the period of one year, clinical progression was observed. The intracranial tumor extended. It was shown in diagnostic imaging. The patient was operated on by neurosurgeons with histopathology verification. In the later stage she underwent radiotherapy. The case has been described because of its diagnostic and therapeutic difficulties.

[Persistent hyperplastic primary vitreous--developmental anomaly of the eye in children].

Persistent hyperplastic primary vitreus in children continues to be a diagnostic and therapeutic challenge for ophthalmologists. It can occur in isolation, in association with other ocular disorders and rarely as a part of systemic disorder. Characteristic features include microphthalmic eye, white vascularized retrolental tissue with or without a persistent hyaloid artery, centrally dragged ciliary processes, an anteriorly shifted and (or) swollen lens, and varing degrees of lenticular opacification. PHPF is the most common associaton with unilateral cataracts. Differential diagnosis and functional effect of treatment are discussed.

[Scleritis posterior in child--case report].

We present the case of 13-years old girl with recurrent unilateral painful proptosis and associated with other ocular features: loss of vision, disc edema, macular edema, folds at the posterior pole. Ultrasound examination with CT scan were necessary to make the differential diagnosis of orbital tumors. The patognomonic sign "T" on B scan was extremely essential in the clinical diagnosis of posterior scleritis.

[Surgical treatment of lens dislocation in children--analysis of complications].

PURPOSE: To present the surgical complications in eyes with ectopia lentis in children. MATERIAL AND METHODS: 116 eyes of 65 children were operatively treated for lens dislocation. Pars plana lensectomy, vitrectomy and IOL implantation with scleral fixation were done in all eyes. Time of observation ranged between 1-6 years (mean 3.4). RESULTS: There were no serious intraoperative complication (mainly hemorrhage to anterior and posterior chamber). Postoperative complications included retinal detachement in 3 (2.6%) eyes and endophthalmitis in 1 (0.8%) eye, were the major complications observed in all patients. Complications related to scleral fixation included exposure of the scleral fixation suture in 8 (6.9%) eyes, lens decentration in 9 (7.8%) eyes, pupil capture in 3 (2.6%). CONCLUSIONS: The surgical procedure is useful and safe in the management of subluxated lenses in children.

[The estimation of functional results after surgical treatment for ectopia lentis in children].

PURPOSE: To review the visual outcome of planned pars plana lensectomy and vitrectomy with posterior chamber intraocular lens implantation for ectopia lentis in children. MATERIAL AND METHODS: Between 1997-2002, 116 eyes were operated because of lens subluxation, mainly because of decreased visual acuity (<0.4). Lens subluxation was associated with homocystinuria in 4 patients (8 eyes), Marfan's syndrome in 30 (54 eyes), congenital simple ectopia lentis in 16 (31 eyes), post trauma in 6 (6 eyes), and congenital ectopia lentis and pupillae in 9 (17 eyes). Time of observation ranged between 1 to 6 years (mean 3.4). RESULTS: After surgery, we achieved best-corrected visual acuity improvement in 89%. Unsatisfactory visual results were due to amblyopia (9 eyes), complications of retinal detachement surgery (3 eyes), uveitis (2 eyes), glaucoma (1 eye). CONCLUSIONS: Pars plana lensectomy, vitrectomy and scleral-fixated IOL implantation give quick and good functional results. To achieve these results, visual rehabilitation and amblyopia treatment is necessary.

[Surgical management of pathologic filtering blebs in pediatric glaucoma].

The aim of this paper is to present our own experience in the treatment of cystic blebs in children and young adults. This complication, which is the most popular after trabeculectomy with antimetabolic agents, can be the reason of late endophthalmitis. Surgical treatment is one of the method to prevent it. In the study 6 patients with cystic blebs after trabeculectomy with mitomycin C was presented. 4 of them was treated surgically. We described the method of surgery and the results.
