Informativity of microperimetry in retinal pathology diagnosis

The purpose of the study is to estimate the functional status of central retinal zone with microperimetry method in patients with retinal pathology. Material and Methods. Microperimetry was performed on 16 patients (18 eyes) with different kinds of retinal pathology including thrombosis of central retinal vein branches, age-related macular degeneration, myopic maculopathy, lamellar macular hole, tapetoretinal degeneration, ocular albinism, central serous choriretinopathy, proliferative diabetic retinopathy. Mean age was 52.4 years old; male - 8, female - 8. Results. The average light sensitivity of central retinal zone was reduced in the majority of patients. The decrease in the index of retinal light sensitivity in the pattern point corresponding to fixation point did not correspond to the decrease in the best-corrected visual acuity in all cases. Central defects and depression zones topographically corresponded to pathological alterations on the eye fundus. In a patient with ocular albinism fixation was characterized as unstable, in the rest of cases we observed stable fixation. The analysis of fixation allowed receiving additional information about visual quality and the degree of visuomotor coordination in patients with retinal pathology. Conclusion. As a result of the study we showed high informativity of microperimetry for assessing central retinal zone's functional status in retinal pathology.
