[Choroidal neovascularisation in pathological myopia: epidemiological data from a health services research study conducted in Germany].

Pathological myopia (PM) or high myopia is defined as excessive short-sightedness (more than -6 dioptres) caused by a strong dilation of the bulbus oculi, that can induce the development of new and unstable vessel structures [choroidal neovascularisation (CNV)]. Since there are only limited epidemiological data available on PM, this health services research study was conducted.A health services survey with ophthalmologists throughout Germany was undertaken. Physicians were asked to complete a 51-item questionnaire on CNV in PM as well as on its early stages in their daily practice, diagnosis, control and treatment, patient numbers and evaluation of health care situation. Statistical analyses were entirely descriptive.Of 7,500 ophthalmologists, a representative sample of 800 was randomly selected; 340 physicians took part. The mean prevalence rates/year/practice were 1,765.5 ± 1,218.1 with myopia, 230.7 ± 278.6 patients with high myopia, subdivided into 129.3 ± 242.8 patients with PM without macular degeneration (MD), 39.6 ± 64.8 patients with PM and MD, and 13.3 ± 30.3 patients with PM and CNV. Data on diagnosis and control show a lack of clearly defined standardisation. With regard to treatment of CNV in PM the data show the current discrepancy of guideline recommendations and approved treatment options.The prevalence and incidence data collected in this study vary considerably between physicians. This may be explained by the various grades of specialisation as well as to possibly existing uncertainties regarding the definition and nomenclature of PM/high myopia and their different stages of the disease that should be harmonised. A generally accepted definition of severity grades, recommendations on diagnosis as well as detailed information and continuous training programmes on this disease is necessary.     «
