Summary
Heredo-oto-ophthalmo-encephalopathy (HOOE) causes vision loss due to cataracts and retinal neovascularization. This familial amyloidosis also involves extensive retinal glial cell changes, impacting ocular health.
Area of Science:
- Ophthalmology
- Neurology
- Genetics
Background:
- Heredo-oto-ophthalmo-encephalopathy (HOOE) is a rare, dominantly inherited neurodegenerative disorder.
- Characterized by progressive vision loss, hearing impairment, ataxia, and dementia.
- Ocular manifestations of HOOE have not been previously detailed.
Purpose of the Study:
- To describe the ocular changes in Heredo-oto-ophthalmo-encephalopathy (HOOE).
- To analyze clinical and histological data from affected family members.
Main Methods:
- Full ophthalmological re-examination of three affected individuals.
- Postmortem histological examination of eyes from two affected individuals.
Main Results:
- Visual loss attributed to posterior subcapsular cataract and retinal neovascularizations.
- Retinal neovascularizations led to vitreous hemorrhages and neovascular glaucoma.
- Extensive amyloid deposition in the retina and retinal vessels; pathological changes in glial cells, including Müller cells occluding vessels.
Conclusions:
- HOOE is a familial amyloidosis affecting the central nervous system.
- Distinct from other amyloidosis due to the presence of cataract and retinal neovascularizations.
- Retinal glial cell changes are significant and may contribute to ocular pathology in HOOE.
