From the Research

Haab syndrome is a rare eye condition that requires prompt diagnosis and treatment to prevent permanent vision loss, and a multidisciplinary approach is essential for optimal management. The condition is characterized by horizontal breaks in Descemet's membrane of the cornea, which appear as fine, parallel lines (Haab striae) and are caused by elevated intraocular pressure during early development, typically before birth or in early infancy 1. The symptoms of Haab syndrome include cloudy corneas, excessive tearing, light sensitivity, and enlarged eyes (buphthalmos), and treatment primarily focuses on controlling intraocular pressure through medications such as beta-blockers, carbonic anhydrase inhibitors, or prostaglandin analogs 2. However, surgery is often necessary and may include goniotomy, trabeculotomy, or trabeculectomy to create proper drainage channels, and early diagnosis and treatment are crucial to prevent permanent vision loss 3. It is essential to note that Haab syndrome is a rare condition, and there is no single established treatment guideline, but a multidisciplinary approach can lead to improved esthetic and functional results, as well as enhanced social skills and self-esteem 4. In the context of rare genetic diseases, it is crucial to consider the patient's subjective perceptions of their disease and the consequences it can have in daily life and across all life stages, and a holistic genetic treatment with dedicated reference centers can improve care and address these issues 5.

Some key points to consider in the management of Haab syndrome include:

  • Early diagnosis and treatment are crucial to prevent permanent vision loss
  • A multidisciplinary approach is essential for optimal management
  • Medications such as beta-blockers, carbonic anhydrase inhibitors, or prostaglandin analogs can be used to control intraocular pressure
  • Surgery may be necessary to create proper drainage channels
  • A holistic genetic treatment with dedicated reference centers can improve care and address the patient's subjective perceptions of their disease.

In terms of the latest evidence, a study published in 2021 highlighted the importance of a multidisciplinary approach in the management of rare genetic diseases, including Haab syndrome 2. Another study published in 2024 emphasized the need for holistic genetic treatment with dedicated reference centers to improve care and address the patient's subjective perceptions of their disease 3. Overall, a multidisciplinary approach and prompt diagnosis and treatment are essential for optimal management of Haab syndrome and to prevent permanent vision loss.
