This prospective study shows that cataract surgery with anterior vitrectomy is advantageous in younger patients concerning after-cataract formation. The AcrySof SA30AL maintains good centration, produces minimal inflammation, and is well tolerated in the pediatric eye.
IntroductionCataract surgery in children has changed and improved dramatically during recent decades. This is mainly a result of modern surgical techniques and improved intraocular lenses (IOLs).
Combined surgical method of treatment of progressive capillary hemangiomas by using cryosurgery and surgical excision in infants allows the choice of optimum tactics depending on features of the course and clinical picture in each individual case and provides achievement of high cosmetic and functional result of treatment. The early beginning of treatment in cases of fast progressing of the tumor allows prevention of extensive skin affection and amblyopia development.
The newly developed surgical technique for BPES correction by means of levator resection permits one to obtain high cosmetic and functional results based on improvement of the topography of the upper eyelid and orbital structures.
Purpose. Elaboration of the new method of salvage retinoblastoma (RB) treatment, combining local and systemic chemotherapy. Material and methods. Salvage treatment using the new method was carried out in 71 children aged 2 months – 7 years on 102 eyes with RB in T1–T3 stages. At the Department of Pediatric Ophthalmopathology of SI «The Filatov Institute of Eye Diseases and Tissue Therapy of NAMS of Ukraine» the method of combined polychemotherapy (CPCT) was developed in 2010: primary IViC – injection of 0,01 µg (0,1 µg) Melphalan through pars plana; a course of CEV-protocol (drugs combination: Carboplatin + Etoposide Phosphate + Vincristine Sulfate) chemoreduction the next day after injection; monitoring the state of the tumor with repeated courses of SPHT every 3 weeks; addition of CPCT by focal destruction methods according to indications. In order to increase the ablasticity of IVi injections, we have developed the antireflux method of their implementation: to reduce IOP the diuretic injection is preliminarily performed in age-related dosage; puncture of the conjunctiva at the distance of 1–1,5 mm from the intended sclera puncture and its displacement above the IVi injection site; puncture of the sclera with obliquely perpendicular injection channel formation; IViC by cytostatic Melphalan in a volume of 0,1 ml in various dilutions depending on the indications; in repeated IViC – in different meridians; removing the needle with one-step tamponade of the injection site by cotton swab, antibiotic solution injecting under the conjunctiva with roller formation. Results. Ten-year experience of using the developed algorithm of salvage RB treatment by combined polychemotherapy, based on primary intravitreal melphalan chemotherapy (using the proposed antireflux injection method) with simultaneous systemic chemoreduction, proves its safety and effectivity – 77.5% regression of the tumors. Conclusion. Simultaneous action on the tumor of various cytostatics – one (melphalan) intraocular directly on the tumor and its vitreal clones, others – (carboplatin, etoposide, vincristine) – from the peripheral blood – creates the effect of «double blow» on RB cells. Key words: retinoblastoma, salvage treatment, combined polychemotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
