Global data on visual impairment in the year 2002.

This paper presents estimates of the prevalence of visual impairment and its causes in 2002, based on the best available evidence derived from recent studies. Estimates were determined from data on low vision and blindness as defined in the International statistical classification of diseases, injuries and causes of death, 10th revision. The number of people with visual impairment worldwide in 2002 was in excess of 161 million, of whom about 37 million were blind. The burden of visual impairment is not distributed uniformly throughout the world: the least developed regions carry the largest share. Visual impairment is also unequally distributed across age groups, being largely confined to adults 50 years of age and older. A distribution imbalance is also found with regard to gender throughout the world: females have a significantly higher risk of having visual impairment than males. Notwithstanding the progress in surgical intervention that has been made in many countries over the last few decades, cataract remains the leading cause of visual impairment in all regions of the world, except in the most developed countries. Other major causes of visual impairment are, in order of importance, glaucoma, age-related macular degeneration, diabetic retinopathy and trachoma.

[Angiolymphoid hyperplasia with eosinophilia with bilateral involvement of the lacrimal glands].

BACKGROUND: Angiolymphoid hyperplasia with eosinophilia (ALHE) and Kimura's disease are two rarely occurring disorders very similar to each other; however, they are individual nosological entities. For a long time they were considered as a single disease due to the frequency of similar characteristics. The majority of authors have recently considered these diseases as two individual entities with some reciprocal specifications, both clinical as well as morphological. PATIENT: We report on the case of a 76-year old male white European who had suffered for more than six years from subcutaneous tumour formations in different parts of the body. Eyelid oedema on the right side with palpable resistance under the upper temporal edge of the orbit initially occurred five years after the first symptoms of the disease. A similar finding occurred on the left side after eight months. The tumours on both sides were surgically removed and sent for histological analysis. A unilateral recurrence of the finding appeared after one year, followed by surgical intervention and histological examination. RESULTS: Tumour infiltrate in the first two orbita excisions was topically related to lacrimal gland structures; these structures were not found in the third excision. The case was histologically diagnosed as ALHE despite some similar characteristics with Kimura's disease. The diagnosis of ALHE was histologically supported, especially by the absence of lymphatic follicle formations and fibrotisation in the infiltrate, and the identification of the appearance of epitheloid up to histiocytoid of proliferating endothelium, which forms small lumens. The diagnosis of ALHE was additionally supported by the fact that the incidence of Kimura's disease in white Europeans is very rare. CONCLUSIONS: According to our findings, both entities overlap one another, even in some characteristics considered to be distinguishing. The question arises, therefore, whether the strict separation of these nosological entities can indeed be determined with one hundred percent accuracy.

Eye health care in the Czech Republic.

OBJECTIVE: An analysis of eye health care in the Czech Republic as of 1998 was performed. METHODS: A questionnaire was used to obtain information from all 59 in-patient eye departments. RESULTS: The number of ophthalmologists per 1 million inhabitants was 95. The number of cataract operations per 1 million inhabitants was 4,209: phaco-emulsification (36,926 surgeries, 85.2%), extracapsular extraction (6,094 surgeries, 14.1%) and intracapsular extraction (90 surgeries, 0.2%). Intra-ocular lenses were implanted in 99% of cases; 404 corneal transplantations and 1,220 operations for retinal detachment were performed. The number of pars plana vitrectomies for diabetic eye complications was 661. CONCLUSION: Selected regional clinical centres should be equipped and preferred by health insurance companies to provide comprehensive eye health care services and training.
