[Structure-function correlation in early diagnosis of glaucoma progression]. / Corelatii structura-functie în diagnosticul precoce al progresiei glaucomatoase.

PURPOSE: The study investigates the correlations between structure and function in early detection of glaucoma progression. MATERIALS AND METHOD: A prospective study was carried on 204 patients diagnosed with POAG and a follow-up period of 4 years. All the patients underwent complex ophthalmological examination, C/D ratio, Disk Damage Likelyhood Scale (DDLS), automated perimetry and Heidelberg retina tomography RESULTS: The relations between structure and function were investigated for all patients, but also according to clinical stage of glaucomatous damage. Structural progression was more frequently associated with perimetric progression for patients with moderate advanced glaucoma. For patients with preperimetric glaucoma and early glaucoma, the progression was present more often for structural test (19,04% and 29,3%), while perimetric progression was less frequent objectivated and weak correlated with structural progression (16,66%). For the 15 cases diagosed with both structural and functional progression, the locations of the structural lesion and functional defect were better correlated in cases involving the poles of the optic disc. CONCLUSIONS: Structure-function relation depends on clinical stage of glaucoma and the location of the glaucomatous defects. In early stages, structural investigations can detect progression before perimetry, while in advanced stages, the functional tests are more useful for early detection of progression.

[Purtscher retinopathy--case report]. / Retinopatia purtscher--caz clinic.

The authors present the case of a 27 years old man who came to our clinic for sudden, painless and profound bilateral loss of visual acuity in both eyes, 14 days ago, during hospitalization for an acute episode of abdominal pain. The clinical aspect correlated with the personal pathological aspects permitted us to establish the diagnosis of Purtscher retinopathy.

[Comparison of angiofluorography and Heidelberg II retinal tomography of the head of the optic nerve in patients with primary open-angle glaucoma]. / Aspecte comparative la angiofluorografie si tomografie retiniana Heidelberg II ale capului nervului optic, la pacientii cu glaucom primitiv cu unghi deschis.

OBJECTIVE: This prospective study aims to evaluate how the vascular involvement of the optic disc, emphasised by angiofluorography (AFG), correlates with morphologic lesions observed by Heidelberg retinal tomography (HRT) II. METHOD: AFG (Visucam Zeiss) and HRT II (with Moorfields regression and keratometry) have been performed on the study group -50 pts. with POAG- and in the control group -25 healthy subjects. Correlations have been calculated with Student (t) and Fisher tests. The value of p<0,05 was considered statistically significant. RESULTS AND CONCLUSIONS: The number and size of hypo-fluorescent areas are significantly bigger in POAG pts. than in healthy subjects. They correlate with the involvement of retinal nerve fibers and C/D value. In POAG pts., areas of hypo-fluorescence are located mainly on the excavation's walls and the neuroretinal ring. Localization on the excavation's floor is not pathological, since it was also observed in the control group. The vascular involvement shown by angiofluorography significantly correlates with morphologic lesions observed by HRT II.

[Diagnostic criteria in acute neuromyelitis]. / Criteriile de diagnostic revizuite pentru neuromielita optica.

Neuromyelitis optica, also known as Devic disease, was identified in the 19th century, is one of the inflammatory idiopathic demyelinating diseases of the central nervous system, often mistaken for severe multiple sclerosis. In 1999 it had been proposed diagnostic criteria for neuromyelitis optica, but in 2006 these criteria were revised by Dean Wingerchuck. These criteria are 99% sensitive and 90% specific for differentiating neuromyelitis optica from multiple sclerosis that present with optic neuritis or a myelitis syndrome. In the following article we present clinical, spinal and cerebral MR imaging, serological and aspects of cerebrospinal fluid examination features of neuromyelitis optica and the revised criteria of neuromyelitis optica established in 2006. The recently identified serum antibody biomarker: neuromyelitis optica immunoglobulin G (NMO Ig G), which target aquaporin 4 water channel, distinguish neuromyelitis optica from multiple sclerosis, is one of the revised criteria of neuromyelitis optica.

[Macular hole--a rare complication of toxocariasis]. / Gaura maculara--consecinta rara a infectiei toxocarozice.

Macular hole is a condition that characterizes older patients, being rare in adolescent patients and exceptionally at children. The etiopathogenic mechanism of most macular holes in children and adolescent is idiopathic. The suggested etiopathogenic mechanism is vitreoretinal traction due to a toxocara granuloma for a 9 years old girl.
