[Trauma to the posterior eye segment].

The paper presents 113 patients with posterior ocular segment injuries hospitalized in a five years period, at the Department of ophthalmology Craiova; they represent 9.3% of ocular injuries and 0.85% of all the patients hospitalized in that period. 81 cases (71.68%) represents posterior ocular contusions, 25 cases (22.12%) represents posterior scleral plaies, and 7 (6.19%) cases represents optic nerve injuries. The functional results depends of anatomicoclinical types of lesions, and of the rapidity of instituation the treatment.

[Ophthalmic migraine].

Ophthalmic migraine is a particular form of essential vascular headache, which is determined by modification of the vascular tonus at the level of intracranial vessels, especially at the level of occipital cortex. The paper presents the case of a 41-year-old male patient with typical symptoms of ophthalmic migraine which started two years ago. The ocular examination of both eyes is normal. The clinical and paraclinical investigation did not reveal any biological and neuroendocrine dysfunction.

[Computerized perimetry in the diagnosis of glaucoma].

The survey emphasize the great importance of automatized perimetry in showing the perimetric deficits in glaucoma and also the connection between them and degree of modification of optical papilla. 50 records accomplished on 30 patients with glaucoma in various stages are included. RL-30 and RL-60 programmes of a LED-PERS type perimeter were used. The results were compared with a similar ones accomplished on a lot of normal people. The advantages of the automatized perimetry are the capabilities in detecting the deficits and measuring them by recording the sensitivity levels, and the great possibilities of graphical output, storing and retrieving of the information.

[A morbidity study of intraocular foreign bodies].

190 patients presenting intraocular foreign bodies, hospitalized between 1981-1991, are examined. The study of accidents: cases showed a clear prevalence of work accidents--127 cases (66.84%); 86 of these cases occurred in industry (45.26%), the rest of 41 occurred in agriculture (21.58%). The professions most exposed to such accidents are those of locksmith, mechanic in agriculture or automobile industry. The postsurgical evolution and the incidence of complications show that intraocular foreign bodies are wosse-making factors of ocular plagues, because of anatomical structures disorganization, transparency modifications and infectious complications implied, which determined the diminishing of visual acuity in 88.08% of cases. The big percentage of work accidents in the etiology of intraocular foreign bodies emphasize the great importance of foreign the work-protection rules (regarding a especially the wearing of protection glasses) and of introducing of automation in technological processes involving great risks.

[Ocular complications in zona ophthalmica].

81 cases of herpes zoster ophthalmicus with ocular affection, hospitalized in the clinic of ophthalmology between 1980-1991, are presented. The most frequent ocular complications were dendritic keratitis and punctate epithelial keratitis in 12 cases, neurotrophic keratitis in 7 cases, keratoendothelitis in 22 cases, iritis and iridocyclitis in 26 cases posterior uveitis in 3 cases. Seldom complications, presented each with a single case, were secondary glaucoma, optical postnevritical atrophy, oculomotor nerves palsy. The lesions were equally distributed between the two eyes. The associations of these complications determined visual acuity diminishing below 1/10 in 27 cases. In spite of association of classical treatment with recent antiviral medication and due to serious ocular complications which appear at most of 50% of the patients with herpes zoster ophthalmicus, the functional prognosis remains reserved.

[Tuberculosis of the tarsal conjunctiva].

A woman sixty-five old presents one pronounced swelling of the eyelids at the both eyes with the appearance of the multiple chalasions. The patient at twenty-six years old presented pulmonary tuberculosis, in the present stabilized. The morphopathology exam by a fragment of tarsus and conjunctiva shows an lymphocyt inflammatory infiltration with the presence of the epithelial cells and caseation areas. At level of conjunctiva it constats the presence of tuberculum follicles that are present too at the level of Meibomius canals of excretions. The disease is considered like an allergical reaction at endotoxin of Koch bacillus, secondary by some old tubercular lesions.

[Capsulotomy through the pars plana in the eye with pseudophakia of the posterior chamber].

It described one surgical technique for capsulotomy in the case of secondary cataract at an eye with pseudophakic by posterior chamber. The approaching makes with an simple instrument, through pars plana, the tearing of posterior capsule making under control with operator microscope, in area of visual axie, excluding any possibility to harm the lens, its luxation in vitreous or anothers complications.

[Variations in intraocular pressure in normal-pressure glaucoma and in hypertensive open-angle glaucoma].

The comparative study of the intraocular pressure variations at patients with low-tension glaucoma and hypertensive open-angle glaucoma reveals some common modifications regarding the aspect of the nictemeral levels of intraocular tension (the maximal variation of the nictemeral curve, the time of maximal intraocular pressure, variability) and the aspect of the provocative testes. The nictemeral curves and the provocative testes are used at the patients suspects of low-tension glaucoma both for diagnose and to eliminate the incipient open-angle glaucoma with one tensional pick.

[Progressive dystrophy of the cones].

The 31-year-old female patient preserved photophobia, learning tiredness, pigmentary remaniations in the macular region to both eyes. With emphasis on the right eye. The photopic visual field shows a paracentral scotoma, 4 degrees inferior at the right eye, without the modification of the peripheric isopters. The darkness adaptation curve is monophasic, with reduction and delay of the alpha angulation. The chromatic sensation exam shows protanomaly. Angiographically, isolated macular lesions with the pigmentary epithelium atrophy and the persistency of the fluorescein in late venous time are confirmed. A genetic deficit of the membrane receptors, at the level of the pigmentary epithelium cells, might explain the selective dystrophia of the cone cells. The different renewal process of cones, compared to the stick cells, stays at the origin of selectively separated pathological processes.

[Possible environmental factors in oral pathology].

A study has been undertaken on 540 patients working in three different industry branches. As a result there have been established correlations between different forms of oral pathology and factors susceptible to be aetiologic.
