Abstract:
PURPOSE: Age related macular degeneration (AMD) is the leading cause of legal blindness in patients aged 65 years or over in the Western world. The foveal damage affected their ability to read, recognize faces, watch TV, and drive. Increasing the size of retinal image by angular magnification devices might offer the only means for improving the visual function, therefore we implanted IMTTM (Implantable miniaturized telescope) into posterior chamber. METHODS: We experienced a case of bilateral dry type AMD in 72 years old female patient with mild cataract. Her uncorrected visual acuity was 20/500 (OU) with ETDRS chart. Near visual acuity shows 20/500 M (OD), 20/630 M (OS) with +3 D glasses. We performed successfully an ultrasonic phacoemulsification and IMTT M (Vision Care, Israel) lens implatation into the posterior chamber using a large scleral tunnel incision (170 degrees) on her right eye. RESULTS: One year following surgery, visual acuity improved up to 20/100 (20/40x+1.5 Ds) in her right eye, with possible compensatory improvement of left vision of 20/500 (20/50x+1.5 Ds). Near visual acuity was (1.0 Mx+4.5 Ds)(OD), (0.63 Mx+4.5 Ds)(OS). In addition she was able to watch TV and read the letter display, and read Bible. CONCLUSIONS: IMTTM is may be very useful for vision improvement in bilateral AMD patients.
