Alport syndrome: a review

Alport syndrome, a hereditary nephritis accompanied by high-tone sensorineural deafness and distinctive ocular signs was first noted in the literature during the early 1900s. This disease is caused by a genetic defect in Type IV collagen which makes up basement membranes in many body systems. The patient will usually have bilateral anterior lenticonus causing varied refractive errors. You may also note yellow-white to silver flecks within the macular and midperipheral regions of the retina. The treatment of the visual problems is an important but secondary concern due to the seriousness of the systemic disease. Dual sensory loss, however, creates an urgent need for appropriate vision care. Due to the high risk for developmental delay and decreased social integration, early intervention should be considered in the treatment plan. Coping strategies for the patient (and the family) need to be addressed because of the chronicity of this syndrome. The primary care optometrist will be challenged by the individual with Alport syndrome since a balance between oculo-visual, developmental/psycho-educational and systemic care is required. A multi-disciplinary approach by the healthcare management team will enhance the quality of life and positive outcomes for these patients.
