[Pigmentary tumors of the conjunctiva in children: analysis of surgical decision].

Pigmentary tumors of the conjunctiva are rare in children, but they deserve special attention as, under some circumstances, they can question the quo ad vitam prognosis. The management of these tumors is controversial because the clinical diagnosis is uncertain, not reliable for a long term evolution prognosis. In this study, after a short review of the literature, the authors present their own experience in the field (47 cases during the last 10 years, out of which 18 underwent surgery) and they try to develop an algorithm of surgical decision based on age-related factors, clinical appearance, aesthetic factors and on the possibility of establishing a good relationship with the patient and the family.

[Pathology of posterior capsule, a literature review].

The posterior capsule opacification (PCO) is a frequent complication in the modern cataract surgery, uncomfortable for the patient and expensive for the health care system. According to prof. Apple, the main health care expenditure in U.S. is represented by cataract surgery, laser capsulotomy for PCO ranking next. Under these circumstances, it is not surprising that the lens bag pathology and the prevention of aftercataract hold the attention of many research groups all over the world. This paper is a literature review of the last 15 years, presenting the data we have considered to be the most significant.

[Yag-Nd posterior capsulotomy.When? Where? How?].

PURPOSE: To answer a few elementary questions raised when confronted with the patient with aftercataract: Which are the indications and counter indications of the posterior capsulotomy? How can be evaluated the degree of PCO (posterior capsule opacification)? Which are the ideal size and location of the capsular opening? Is it mandatory to dilate the pupil? What energies are to be used? Which would be the recommended follow-up pattern? METHOD: This paper is a retrospective analysis of the 956 posterior capsulotomies performed between January 2001 and December 2002 at Bucharest Eye Hospital, Ophthalmology III Clinic, Nd:Yag laser surgery department. RESULTS: The best outcome is obtained with the fewest complications when the following conditions are met: the capsulotomy is performed no sooner than 6 months postoperatively; the capsular opening is small--2 mm în diameter--but perfectly aligned relative to the pupil and the IOL (sometimes this is difficult to achieve and the surgeon must always bare în mind the geometry of the posterior chamber and the parallax effect); laser pulses have low energy and are posteriorly defocused; when energy higher than 2 mJ is employed, the capsulotomy is performed by applying punctures în a circular pattern instead of a crosslike rectilinear pattern (in the case of IOL pitting, the visual axis is spared). CONCLUSION: The Nd:Yag photodisruptive laser offers a swift, safe and elegant method for dealing with a common and disturbing complication of the modern cataract surgery, the posterior capsule opacification. The results are often spectacular from the patient's point of view, but one should not neglect the risks related to the posterior capsulotomy.

[Carcinoma of the lacrimal sac].

The present paper reports on the case of a 63 year-old woman twice operated for chronic suppurated dacryocystitis. At the third operation the lacrimal sac which was enlarged and rigid was removed. Section of the sac revealed a pinkish-grey formation that occupied the entire lumen of the sac. Histologic examination showed a poorly differentiated carcinoma with an islet-alveolar distribution. Stress is laid on the rare occurrence of primary malignant tumours of the lacrimal sac and the diagnostic difficulties in the onset period.

[Bilateral transverse optic neuropathy].

It shows a clinical observation about optical anterior juxtabulbar bilateral neuropathy, with superacute debut, rapid and dramatic evolution in the first days, at a young woman. The disease established the marked diminuation of the visual acuity and the collapse of the visual field. The evolution was favourably under the cortisone therapy, establishing the total recovering of the visual function. Are discussed appearances about etiology and clinical specific features of optical juxtabulbar neuropathy, considering this isolated optical neuropathy like a first attack in evolution of one sclerosis in plaques.
