[Genetic implications and therapeutic possibilities in the course of hereditary macular pathology and vitreoretinopathies].

There are many hereditary diseases in ophthalmology including retinal dystrophies--diseases of great heterogeneity requiring genetic determination, individual or in entire family.

[Effect of hemodialysis in retinal circulations].

In patients with chronic renal failure undergoing hemodialysis were recorded and studied by various authors multiple eye damage with time. Studying the literature we conducted a study to assess the impact of intradialitic-interdialitic and postdialitic volemic game above the retinal circulation. By measuring diameters of retinal circulation after processing the digital fundus, we found that, 30 minutes after hemodialysis session takes a degree of dilatation of retinal vessels, permanent vascular insult that can be responsible for stroke and ischamic eye and coronary diseases of these patients.

[Posttraumatic hyphema with secondary glaucoma].

The authors present in detail (symptoms, signs, predisposing factors, complications, treatment) one of the most common signs seen in the eyeball contusion--traumatic hiphema. There are presented concepts for proper treatment of hiphema with secondary glaucoma and for relapsing hiphema.

[The impact of hemodialysis on retinal circulation].

Studying the literature we conducted a study to assess the impact of intradialitic-interdialitic and postdialitic volemic game above the retinal circulation. By measuring diameters of retinal circulation after processing the digital fundus, we found that, 30 minutes after hemodialysis session takes a degree of dilatation of retinal vessels, permanent vascular insult that can be responsible for stroke and ischamic eye and coronary diseases of these patients.

[Normal tension glaucoma].

Normal Tension Glaucoma is known to be a special form of glaucoma which is still a matter of dispute in its etymologic, diagnostic, therapeutic aspects and in its terminology. The diagnosis of normal tension glaucoma is by elimination of other disorders by pachymetry, tonometric curve, neurologic examination and sometimes MRI. What remains may be a locus minoris of general pathology.

The surface of the eye--a superficial entity with deep repercussions.

The surface of the eye is an anatomical and functional entity with a relatively recent delimitation but with significant therapeutic and diagnostic consequences. The pathology of the conjunctive and cornea must be approached by looking at the interrelations between the two tissues that are so different anatomically and functionally but in the same time form a unit in structuring the eye's surface. There are two major categories of relations between the two tissues: one of them is mediated by lachrymal secretion, a process whose complexity is not yet fully understood, and the other is germinal, referring to the stem cells located at the limbus which become epithelial cornea cells that can fixate lachrymal fluid.

[Assessment of compressive optic neuropathy in hipofizar tumors].

Purpose: Assessment of optic nerve head configuration in eyes with compressive optic neuropathy due to pituitary tumors--morphological aspects of "band atrophy" (documented by fundus biomicroscopy and digital stereo disc photography) and quantitative analysis of topographic changes (testing the abilities of HRT and OCT in detection and analysis the specific pattern of nerve fiber layer loss in chiasmal compression).

Material And Methods: Optic disc morphological assessment of compressive optic neuropathy in 56 patients with pituitary macroadenomas (documented by direct ophthalmoscopy, fundus biomicroscopy using Volk lens of 90 degrees and digital stereo disc photography using Zeiss Visucam digital camera). Stereometric analysis of "band atrophy" using HRT in 9 cases and OCT in 5 cases.

[Principles of treatment in ocular burns regarding the ocular surface and limbal stem cells].

The term ocular surface emphasizes the functional interdependence of the nonkeratinizing epithelium of cornea and conjunctiva. The limbal stem cells are responsible for replacement of corneal epithelium following ocular surface injuries. Over the past decades important advances in the management of chemical injury have occurred based on the application of theories on ocular surface and limbal stem cells.
