Background: Autologous bone marrow-derived lineage-negative (Lin-) cells present antiapoptotic and neuroprotective activity. The aim of the study was to evaluate the safety and efficacy of novel autologous Lin- cell therapy during a 12-month follow-up period.
Methods: Intravitreal injection of Lin- cells in 30 eyes with retinitis pigmentosa (RP) was performed.
Purpose: To evaluate the validity of electrophysiological tests in the early diagnosis of a ganglion cells and/or optic nerve dysfunction in patients with pituitary microadenoma.
Methods: 66 eyes, from 33 patients with microadenoma with no evidence of the optic chiasm compression in magnetic resonance imaging (MRI) and the visual impairment in the routine ophthalmological examination, standard static perimetry (24-2 white on white) and optical coherence tomography (HD-OCT), were analysed. The pattern electroretinogram (PERG), standard pattern visual evoked potentials (PVEPs) and multichannel visual evoked potentials (mVEPs) (ISCEV standards) were performed.
Purpose: To compare the 27G versus 25G vitrectomy in patients with epiretinal membrane (ERM).
Patients And Methods: Sixty pseudophakic eyes of 60 consecutive patients treated by pars plana vitrectomy (PPV) using 27G (30 eyes) or 25G (30 eyes) were prospectively evaluated including eye's inflammation, surgery time, ERM + ILM removal time and complications. Additionally, 1, 3, 7, 14, 30, 90 and 180 days after PPV, the following were estimated: intraocular pressure (IOP), sclerotomy wound closure time, distance best corrected visual acuity (DBCVA), foveal macular thickness (FMT) and surgically induced astigmatism (SIA).
Background: Inflammation associated with biomaterials of Ahmed® glaucoma drainage devices may cause the formation of a capsule around the device and can thus have a significant influence on the level of intraocular pressure reduction.
Objectives: The objective of this study was to compare the clinical outcomes after the implantation of a polypropylene or silicone Ahmed® glaucoma valve in patients with neovascular glaucoma.
Material And Methods: In the study, 27 eyes with neovascular glaucoma (group 1) received silicon Ahmed® valves and 23 eyes (group 2) received polypropylene valves.
Purpose: To evaluate macular function and structure before and after epimacular membrane surgery and to estimate the usefulness of pattern ERG test parameters in predicting the postoperative visual acuity.
Methods: We evaluated 32 eyes of 32 patients (mean age 70.8 ± 6.

Nepafenac is an innovative non-steroidal anti-inflammatory drug used in ophthalmology for the prevention of macular edema after cataract surgery. Along with its anti-inflammatory effect, nepafenac has some unique properties which distinguish it from other non-steroidal anti-inflammatory drugs. It is a prodrug activated to amfenac after it penetrates through the corneal layers to the aqueous humour and the ciliary body.

Methods: Thirty two eyes of 17 patients with AF were analyzed. The full-field electroretinogram (ERG), pattern electroretinogram (PERG) and pattern visual evoked potential (PVEP) were performed.
Purpose: To assess the suitability of galantamine for the symptomatic treatment of post-traumatic oculomotor (III) and trochlear (IV) nerve palsy.
Material And Methods: The routine ophthalmic and strabological examination was performed in five patients (4 females and 1 male) at the age of 31 to 57 years (mean 40.7) with the post-traumatic ophthalmic complications.
Purpose: To assess the retinal ganglion cells function in patients with ocular hypertension (OHT).
Material And Methods: In one hundred eyes of 50 patients with ocular hypertension [mean age: 48 +/- 13 years, intraocular pressure mean: 26 +/- 3.0 mmHg; Humphrey Field Analyzer (HFA) 24-2 W-W mean deviation (MD) > -2 decibels (dB), normal optic nerve fiber layer results in scanning laser polarimetry (GDX)], PERG recordings were performed according to the modified methodology described by Parisi V et al.
Aim: The aim of our study was to evaluate the visual acuity, visual field, retinal bioelectrical function and fluorescein angiography (FA) results of patients with exudative AMD treated with an intravitreal injection of triamcinolone acetonide (IVTA).
Material And Methods: Visual acuity (Snellen chart), Humphrey automatic static perimetry (HASP) 30-2 W-W, mfERG were performed before, one month and three months after a single intravitreal injection of about 20 mg triamcinolone acetonide in 17 eyes of 17 patients (that did not meet the criteria for PDT). Fluorescein angiography was evaluated before and 3 months after treatment.
Purpose: To evaluate the mfVEP test in detection of the optic nerve neuropathy in pituitary tumors.
Material And Methods: We examined 30 eyes of 15 patients with confirmed by MRI pituitary tumors (7 patients with macroadenomas and 8 patients with microadenomas). In all patients the routine ophthalmologic examination, multifocal visual evoked potentials (mfVEP) and standard static perimetry (central 24-2 threshold), were performed.
Introduction: To estimate the in vitro level of L-ascorbic acid radical in lenses of patients with senile or diabetic cataract using EPR (Electron Paramagnetic Resonance) spectroscopy.
Material And Methods: 24 human cataractous nuclei obtained during extracapsular removal were used. 5 of them (21%) were from diabetic patients.
Purpose: Occult macular dystrophy (OMD) is an unusual, inherited macular dystrophy characterized by a slowly progressive decline of visual acuity with normal fundus and fluorescein angiography (FA). The authors present a 43-year-old man who was diagnosed as having OMD because of the results of electrophysiological, psychophysical, optical coherence tomography (OCT) tests.
Methods: Routine ophthalmological evaluation, FA, visual field tests, electroretinographic examinations (EOG, ERG, PERG and mfERG recordings according to ISCEV standards) and foveal thickness measurements (OCT) were performed.
Introduction: The aim of our study was to evaluate the visual acuity, visual field, retinal bioelectrical function and fluorescein angiography results in patients with subfoveal choroidal neovascularisation treated with photodynamic therapy (PDT).
Material And Methods: Visual acuity (Snellen chart), static perimetry (PS 30-2 W-W), mf-ERG (according to ISCEV standards) and fluorescein angiography were performed before, 3 and 6 months after initial photodynamic therapy in 20 eyes of 18 patients.
Results: There was no significant change in the average visual acuity after 3 and 6 months after PDT comparing to the initial examination, although the visual acuity improved in individual cases from 1 to 5 lines.
