Objectives of publication:presentation of a rare clinical observation from our own practice.Key points:colobomatous orbital cyst with microphthalmos — rare anomaly of an embryonal development of an eyeball, it is formed owing to “filling” of an optic nerve with the intraocular liquid coming to him from a vitreous chamber through сoloboma of disk because of violation of hydrodynamics in a forward segment of an eye. Usually this anomaly is combined with microphthalmic eye, though cases of a colobomatous cyst with a normal size of an eyeball, and also with other anomalies of development of an eye (inferior uveoretinal coloboma, prepupillary membrane, corneal opacity) are described.Сlinical observation:during 2015 in our department there were two children to whom after the carried-out inspection the diagnosis of a colobomatous cysts of optic nerve has been exposed. Concerning the first child waiting tactics has been recognized expedient, at repeated surveys in 1 and 4 months of any dynamics in the ophthalmologic status it hasn’t been revealed. To the second child because of the expressed exophthalmos with lagophthalmia, with perforation threat, surgical intervention – a puncture and drainage of a cyst of an optic nerve is performed. After operation the correct situation and mobility of an eyeball were restored, xerotic changes of a cornea and conjunctiva have decreased.Conclusions:from the pathogenetic mechanism of cystous formation of an orbit, it is more logical to specify the clinical diagnosis a mention in him an optic nerve – “сolobomatous cysts of optic nerve”. Surgical treatment depends on the sizes of cyst, degree of exophthalmos and existence of complications.
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.
