A Model Project to Provide Outreach Low Vision Services to Children with Deaf-Blindness

The main conclusions of this project are: a) the overall quality of evidence in the literature concerning deaf children and their ophthalmic problems is very low, b) the prevalence of ophthalmic problems in deaf children is very high (approximately 40% to 60%) and these problems may remain undetected for years although they may have a serious impact on children's acquisition of communication skills, c) screening for ophthalmic problems in deaf children should be encouraged and specialist ophthalmic examination should be carried out as soon as the diagnosis of deafness is confirmed irrespective of age, and may need to be repeated at intervals following diagnosis, d) families should be informed about the nature of the screening process in discussion with the relevant professionals and appropriate information should be available in a range of formats and in different community languages, e) professionals administering the tests should be familiar with the needs of deaf children with ophthalmic problems and should be sensitive to the communication needs of the child, especially undertaking behavioural testing where their collaboration is needed, f) while orthoptists can perform the majority of psychophysical tests (visual and stereo acuity tests, ocular motility tests, etc.) a comprehensive opthalmologic assessment by slit lamp biomicroscopy, streak retinoscopy, direct and indirect ophthalmoscopy, intraocular pressure measurement etc is required. Electrophysiologic testing to help identification of Usher syndrome may also be required, and finally g) serial hearing assessments of children with dual sensory deficits are needed to monitor hearing thresholds, to optimise hearing aid use and to ensure timely referral for cochlear implantation for those who need it.
