Visual impairment and blindness in Europe and their prevention.

The European region currently differs in many aspects, such as political, socioeconomic, and geographical. After substantial political changes at the beginning of the 1990s, the majority of central and eastern European countries started to rebuild their healthcare systems. It is apparent that eastern Europe represents a highly diverse region where the difference among countries broadens year after year. In highly industrialised countries of Europe, the leading causes of childhood serious visual loss are lesions of the central nervous system, congenital anomalies and retinal disorders. In the middle income countries of Europe, congenital cataract, glaucoma and, mainly, retinopathy of prematurity are highly expressed. The major cause of serious visual loss in adults in industrialised countries is age related macular degeneration. The other conditions comprise cataract, glaucoma, diabetic retinopathy, and uncorrected/uncorrectable refractive errors, along with low vision. In people of working age, diabetic retinopathy, retinopathy pigmentosa, and optic atrophy are the most frequently reported causes of serious visual loss. In the middle income countries of Europe, advanced cataract, glaucoma, and diabetic retinopathy are more frequently observed.

Eye healthcare services in eastern Europe: Part 1. Cataract surgery.

AIM: To describe cataract surgical services in 1998 in 12 eastern European countries and to identify their needs to reduce cataract blindness. METHODS: All inpatient eye departments in the 12 countries received a standardised questionnaire; the data obtained were further processed at the coordinating centre in Prague. RESULTS: All 458 eye departments in the region were involved. The response rate was 100%, except for Bulgaria (93%) and Romania (93%). The total number of cataract surgeries per one million inhabitants in 1998 was calculated: Belarus (800), Federation of Bosnia and Herzegovina (1275), Bulgaria (1730), the Czech Republic (4210), Estonia (2530), Hungary (3530), Latvia (1860), Lithuania (1550), Trans-Dniester Moldova (1300), Poland (1475), Romania (1260), and Slovakia (2430). Cataracts were mostly operated on by the extracapsular technique. Intracapsular extractions were frequently performed in Federation of Bosnia and Herzegovina (47%), Belarus (46%), Bulgaria (18%), and Romania (14.3%). Phacoemulsification was uncommonly used in 1998, except for the Czech Republic (86%), Estonia (50%), Slovakia (38%), and Hungary (16%). An IOL was implanted in more than 90% of patients in the Czech Republic, Estonia, Hungary, Latvia, Lithuania, and Slovakia. CONCLUSIONS: Conditions for cataract surgery in the eastern European region differ. The main barriers to cataract surgery were state budget limitations, insufficient supply of consumables, underutilisation of operating theatres, and poor detection of patients requiring surgery.

Eye healthcare services in eastern Europe: Part 2. Vitreoretinal surgical services.

AIM: To describe vitreoretinal surgical services in 1998 in 12 eastern European countries and to identify ways for their further improvement. METHODS: All inpatient eye departments in the 12 countries received a standardised questionnaire; the data obtained were processed at the international study coordinating centre in Prague. RESULTS: All 458 eye departments in the region were involved. The number of retinal detachments treated by extraocular surgery, or pars plana vitrectomy, per one million inhabitants respectively, were as follows: Belarus (52; 6), Federation of Bosnia and Herzegovina (21; 2), Bulgaria (39; 19), the Czech Republic (78; 40), Estonia (60; 17), Hungary (81; 88), Latvia (82; 36), Lithuania (68; 6), Trans-Dniester Region of Moldova (6; -), Poland (70; data not available), Romania (24; 25), and Slovakia (67; 55). The number of people per one retinal laser was assessed (in millions): Belarus (1.26), Federation of Bosnia and Herzegovina (2.23), Bulgaria (0.59), the Czech Republic (0.22), Estonia (0.24), Hungary (0.23), Latvia (0.41), Lithuania (0.62), Poland (0.36), Romania (2.25), and Slovakia (0.14). CONCLUSIONS: Conditions for posterior eye segment surgery in the central and eastern European region vary substantially. Underserved regions require (1) more eye doctors trained in surgical and laser retinal treatment; (2) improvement in screening for diabetic eye complications and retinopathy of prematurity; (3) technical equipment for places in need.

Causes of severe visual impairment and blindness in children attending schools for the visually handicapped in the Czech Republic.

AIMS: To describe the causes of severe visual impairment and blindness in children in schools for the visually handicapped in the Czech Republic in 1998. METHODS: Pupils attending all 10 primary schools for the visually handicapped were examined. A modified WHO/PBL eye examination record for children with blindness and low vision was used. RESULTS: 229 children (146 males and 83 females) aged 6-15 years were included in the study: 47 children had severe visual impairment (20.5%) (visual acuity in their better eye less than 6/60), and 159 were blind (69.5%) (visual acuity in their better eye less than 3/60). Anatomically, the most affected parts of the eye were the retina (124, 54.2%), optic nerve (35, 15.3%), whole globe (25, 10.9%), lens (20, 8.7%), and uvea (12, 5.2%). Aetiologically (timing of insult leading to visual loss), the major cause of visual impairment was retinopathy of prematurity (ROP) (96, 41.9 %), followed by abnormalities of unknown timing of insult (97, 42.4%), and hereditary disease (21, 9.2%). In 90 children (40%), additional disabilities were present: mental disability (36, 16%), physical handicap (16, 7%), and/or a combination of both (19, 8%). It was estimated that 127 children (56%) suffer from visual impairment caused by potentially preventable and/or treatable conditions (for example, ROP, cataract, glaucoma). CONCLUSIONS: Establishing a study group for comprehensive evaluation of causes of visual handicap in children in the Czech Republic, as well as for detailed analysis of present practice of screening for ROP was recommended.

[Pneumatic retinopexy: 1 year experience].

We analyzed 13 consecutive cases od retinal detachment treated by pneumatic retinopexy (PR) as a primary method of surgery. The postoperative follow-up period was at least 6 months (mean, 9.9 months; maximum, 15 months). In 11 cases (84.6%) the retina successfully reattached after a single PR. In one case (7.7%) the retina was not reattached primarily because of a missed second tear and in one case (7.7%) the retina redetached due to proliferative vitreoretinopathy. A final reattachment rate of 100% was achieved. The final visual acuity from 0.7 to 1.0 in 10 patients (76.9%) illustrates the fact that PR is a suitable method of surgery in indicated cases of retinal detachment.

[Chronic postoperative endophthalmitis caused by Propionibacterium acnes].

There is a report of three cases of chronic postoperative endophthalmitis following cataract operations. In two patients there was proven Propionibacterium acnes. There is presented a technique to obtain specimens for microbiological examination and an overview of clinical experience in treatment of the mentioned less common types of endophthalmitis. Early surgical treatment as well as intraocular injection of vancomycin can help to restore a good visual acuity despite of longlasting inflammation.

Eye health care in Hungary.

PURPOSE: To describe eye health-care services provided by in patient Departments of Ophthalmology in Hungary as of 1998. METHODS: A standardised questionnaire was sent to all Hungarian in-patient ophthalmic departments. The response rate was 100%, and data from six university departments and 56 hospitals with ophthalmic units are summarised. RESULTS: During the 12-month period, a total of 78,008 ophthalmic operations were performed, by 489 ophthalmologists. They worked in 62 in-patient ophthalmic units having a total of 1952 beds. The cataract rate was 3564 operations per million inhabitants; intraocular lens implantation was performed on 97% of the cases. There were 591 corneal transplants, 1698 operations for retinal detachment and 510 vitrectomies for diabetic eye complications. CONCLUSIONS: The level of ophthalmic care in Hungary, judged on the basis of key objective parameters including number of ophthalmic specialists, number of ophthalmic beds, and the rates of surgery, generally conforms to standards prevailing in Western Europe, in spite of financial difficulties and the consequent lack of investment in new equipment and instruments, both major and minor.
