[Prediction of functional results of extraction in complicated cataract in patients with tapetoretinal abiotrophy].
Relative informative value of various functional methods of investigation was studied in 87 patients with tapetoretinal abiotrophy and complicated cataracts in order to find adequate methods for the assessment of the retinal status before surgery and to define the criteria of visual function prediction. The efficacy of the diagnosis was verified after cataract extraction in these patients. The methods of investigation employed were instrumental electroretinogram (ERG) recording, Hanz-Feld stimulated microERG, high-frequency (40 Hz) rhythmic ERG, electrocoagulograms, determination of electric sensitivity thresholds for the retina and of the optic nerve axial bundle lability (ESL), perimetry, and vision acuity measurements. Rhythmic ERG and ESL were found the most informative; rhythmic ERG amplitude proved to be the most sensitive to macular area involvement, this prompting employment of this method for the prediction of visual functions. Rhythmic ERG helped single out three groups of patients with relatively favorable, doubtful, and unfavorable outcomes.
