H47.12

Clinical Causes: Serious neurological conditions leading to decreased cerebrospinal fluid pressure, such as spontaneous cerebrospinal fluid leaks or post lumbar puncture. Optic nerve diseases coupled with low intraocular pressure, such as degenerative conditions or atrophic optic nerves. Infections or inflammations affecting the eye or optic nerve that result in altered ocular pressure. Previous eye surgeries or treatments that disrupt normal intraocular pressure regulation. Malnutrition or systemic illnesses that affect the eye’s vascular system and optic nerve health.

Key Symptoms: Swelling of the optic disc observable during eye examination. Visual disturbances such as blurred vision or fleeting visual obscurations. Headaches, especially around the eyes or forehead. Changes in peripheral vision. Possible nausea or vomiting if neurological causes are involved. Decreased intraocular pressure readings during assessments.

Diagnosis Path: Diagnosis of this condition involves a comprehensive eye examination, including ophthalmoscopic evaluation to identify optic disc swelling. Additional tests such as tonometry measure intraocular pressure, while neuroimaging scans like MRI or CT scans help identify underlying neurological issues. Lumbar puncture may be performed to analyze cerebrospinal fluid pressure and composition, especially when neurological causes are suspected. The combination of clinical evaluation and diagnostic testing aids in confirming the presence of papilledema associated with decreased ocular pressure.

Treatment Protocols: Treatment strategies depend on the underlying cause of the condition. Management may include addressing neurological issues, such as treating cerebrospinal fluid leaks or infections. If ocular or systemic factors contribute to decreased pressure, supportive therapies are employed. Regular monitoring of visual function and ocular pressure levels is essential. In some cases, surgical interventions or medications may be necessary to correct intraocular pressure or relieve intracranial pressure, thereby reducing optic disc swelling. Multidisciplinary care involving ophthalmologists, neurologists, and other specialists is often recommended.
