[Peculiarities of tear production in patients with dacryoadenitis].

The influence of chronic adenitis and its surgical treatment on tear production and osmolarity was studied. A long-term follow-up (2-65 months) after lacrimal gland extirpation showed a trend for recovery of both basal and reflex lacrimation. Comparison of complaints and functional and pathohistological results allowed to consider retention cysts as a risk factor for dry eye syndrome in the postoperative period.

[Uveal schwannoma mimicking melanoma (case report)].

The article presents a rare clinical case of intraocular schwannoma localized in the pre-equatorial choroidea and the pars plana and complicated by secondary glaucoma. Prolonged course of the disease and the presence of scleral staphyloma allowed to assume benign nature of the tumor. Enucleation was performed due to painful secondary glaucoma. Histological examination of the enucleated eye revealed a choroidal schwannoma. Despite the absence of pathognomonic signs and rare occurence, the possibility of intraocular schwannoma must be kept in mind when examining patients for uveal melanoma.

[Retrospective analysis of causes of enucleations after anti-glaucomatous surgery].

Proximate causes of intraocular pressure (IOP) decompensation accompanied with persistent pain syndrome were determined based on results of morphological examination of 59 eyes enucleated due to terminal previously operated glaucoma and medical history analysis. Excessive scarring, formation of solid hyalinized membrane in the site of filter pad, closure of anterior chamber angle with synechia as an outcome of chronic iridocyclitis and inappropriate surgical approach lead to increase in the resistance of the aqueous humor outflow and result in glaucoma decompensation causing complications that necessitate enucleation. The most common complications are the following: bacterial corneal ulcer with potential perforation and endophthalmitis, hemorrhagic choroidal detachment, vitreous hemorrhage, persistent pain syndrome and phthisis bulbi.

[Histiocytic lesions of the orbit and eye appendages]. / Gistiotsitarnye porazheniia orbity i pridatkov glaza.

2 cases of sinus histiocytosis with massive lymphadenopathy are reported. The disease belongs to non-neoplastic lesions associated with proliferation of histiocytes with antigen-treating function. A case of sarcoma is also described. It consisted of follicular dendritic cells related to histiocytes with the antigen-representing function.

[Lymphoproliferative diseases of the orbit and appendages of the eye]. / Limfoproliferativnye zabolevaniia orbity i pridatochnogo apparata glaza.

The results are available of clinical, morphological, cytological and immunological investigations of orbital lymphomas and lymphomas of appendages of the eye. Malignant lymphoma was detected in 17 patients and reactive lymphoid hyperplasia in 3 patients. All the malignant lymphomas had B-cell phenotype. By cell composition, MALT-lymphoma is more polymorphic than lymphoma from mantle zone cells and lymphoma from small lymphocytes and centro follicular lymphoma. The conjunctive is affected primarily with lymphoma from marginal zone cells or mantle zone cells. As a rule, this is a primary local lesion. Other variants of orbital lymphoma and lymphoma of the eye appendages develop more often as secondary lesions in systemic disease and are characterized by more aggressive course. The key in differential diagnosis of reactive lymphoid hyperplasia and small cells lymphomas is immunophenotyping, especially at initial stages of the tumor process.

[Profuse gastric bleeding in a female with Dieulafois syndrome]. / Profuznoe zheludochnoe krovotechenie u bol'noi s sindromom D'elafua.

Dieulafois syndrome is a rare congenital pathology with profuse gastric bleeding due to the damage to arterial wall in the submucosa layer. The case illustrates difficulties encountered in the treatment of such patients.
