[Diabetic retrohialoidian hemorrage--invasive minimal treatment].

Subhyaloid hemorrhage is defined as a localized detachment of vitreous from the retina caused by the accumulation of blood, which can lead to sudden and severe loss of vision when it takes place in the macular area. The treatment ranges from conservative to posterior vitrectomy depending on the cause, age and the status of other eye.

[Avastin treatment in intraocular tumors].

Bevacizumab is used in the treatment of cancer where it inhibits tumor growth by blocking the formation of new blood vessels (blocking angiogenesis). The purpose of this paper is to evaluate the short-term safety and effectiveness of Avastin injected into the eyeball in cases with intraocular tumors following-up the subjective and objective postoperative results.

[Macular oedema].

Macular edema is a well-known endpoint of ocular diseases, but the pathogenic impact of extra and intracellular fluid accumulation still remains uncertain. While most author favor an extracellular fluid accumulation as the main causative factor, there are indication that Muller cells swelling may also contribute to edema development.

[Electroretinography in monitoring glaucoma patients].

Ocular electrophysiology investigations come back in actuality with new elements; current functional tests involve bias (VF) and require the use of investigations with a high degree of objectivism: full field ERG, pattern ERG, for early detection and monitoring of certain ophthalmic diseases.

[Electroretinography in monitoring of glaucoma (II)].

Pattern ERG represents an effective mean for ocular disease examination where the retinal ganglion cells are lost. Pattern ERG is required as an objective technique in the diagnosis and the tracking of the glaucomatous disease, allowing, with visual perimetry more specific identification of retinal lesions areas.

Evaluation of different surgical techniques in the management of subluxated cataractous lens.

Objective: To compare and evaluate the outcome of different surgical techniques in the management of subluxated cataractous lens.

Material And Methods: This retrospective study included 18 eyes of 18 patients with subluxated cataracts of varying etiology. Their preoperative examination maintain included: best corrected visual acuity (BCVA), thorough anterior segment examination, by slit -lamp especially for the degree and extent of subluxation and cataract, cornea, iris and the pupil for other abnormalities or other traumatic signs, presence or absence of vitreous in the anterior chamber, IOP and finally fundus examination.

Intraocular foreign bodies associated with traumatic cataract.

Objective: To determine prognostic factors and visual outcomes in patients with intraocular foreign bodies (IOFBs) associated with traumatic cataract.

Participants: 19 patients undergoing surgical removal of IOFB and cataract extraction with a minimum of 6-months follow-up.

Outcome Measures: Final best corrected visual acuity was the main outcome where ocular findings at presentation were compared with final visual acuity to determine prognostic factors for visual outcome.

Cystic optic nerve sheath meningioma.

A 58-year-old woman with a 35-year history of left proptosis underwent neuroimaging that revealed a large cystic lesion. Surgery revealed an optic nerve sheath meningioma associated with cyst formation. The cyst was part of the tumor, a phenomenon that is well described in intracranial meningiomas but not in optic nerve sheath meningiomas.

[In vivo study of effects of some alkyl-phenyl-pyridinium compounds after their exposure to optical UV beams].

The purpose of this paper is to study the effects of some alkyl-phenyl-pyridinium compounds (which are in fact cytostatics) on the pseudotumoral tissues after their exposure to optical UV- vis beams.

[Fungal endogenous endophthalmitis--case report].

This paper presents a particular case of endogenous candida endophthalmitis, at a patient with lots of risk factors; the correct diagnosis was relatively late; it had been surgically solved by posterior vitrectomy.

[Yttrium- Aluminium Garnet Crystal (I)].

The Yttrium- Aluminum Garnet Crystal is synthetically obtained and represents the active medium of the Nd: YAG, Ho: YAG, Er: YAG lasers. These solid state lasers showed very good results in Ophthalmology, due to their emission in different regimes (continuous wave or giant short pulses), at different wavelengths (near IR and starting from it in UV or visible spectre), the ability to focus the radiation through simple optic systems or the transmission to narrow, hard accessible spaces using flexible optic fibers. The high efficiency of these lasers reported in ophthalmology is obtained by the photo-disruptive or thermic mechanism of the laser beams.

5-fluorouracil as a phosensitiser.

5-FU exhibits a high fluorescence after irradiation with UV-vis light. An enhancement of the cytostatic activity of 5-FU under UV-vis irradiation was observed on an in vivo experimental model.

Methotrexate as a photosensitiser.

The absorption, excitation and emission spectra of methotrexate (MTX) solutions in natural saline water and sodium hydroxide at 10(-4)-10(-5) MpH=8.4 were measured, while they were exposed to coherent and uncoherent visible and near ultraviolet (UV) light. Xe and Hg lamp and also a nitrogen pulsed laser radiation were used.

[Retinal tumors of the adult--two case reports].

Most frequently, retinal tumors that affect adults are rare, benign lesions that arise from vascular structures (hemangioma), neuroglial structures (astrocytoma, massive gliosis of the retina) or neuroepithelial cells (occasional forms of retinoblastoma that spontaneously stop growing and do not achieve or lose their malignant character). Retinal metastasis might be encountered but the settling of cancer cells at this level is very rare. Retinal tumors have frequently systemic associations and in this case they are included in the phacomatoses syndrome; nevertheless, they can also occur as a nonsyndromic pathological disorder.

[Retinal detachment with giant tears].

Retinal detachments are one of the greatest challenge for the vitreoretinal surgeon. Giant tears have a special place among them because they need a special equipment and experience. We are presenting here our experience concerning this type of tears.
