Summary
A myeloma patient on chemotherapy developed optic neuropathy and retinal necrosis due to cytomegalovirus infection. Prompt diagnosis and antiviral treatment are crucial for immunocompromised patients with visual disturbances.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Oncology
Background:
- Chemotherapy for multiple myeloma can compromise the immune system, increasing susceptibility to opportunistic infections.
- Optic neuropathy and retinal necrosis are severe ocular complications that can arise in immunocompromised individuals.
Observation:
- A 51-year-old male undergoing chemotherapy for myeloma presented with unilateral optic disc hemorrhage and optic neuropathy.
- The condition rapidly progressed to bilateral involvement, exhibiting retinal features of progressive outer retinal necrosis.
Findings:
- Serological tests confirmed cytomegalovirus (CMV) infection with positive immunoglobulin M antibodies.
- Despite treatment with intravenous acyclovir, later switched to ganciclovir, the patient experienced continued visual deterioration and retinal detachment.
Implications:
- This case highlights the critical need to consider and rapidly exclude infectious causes, such as CMV retinitis, in immunocompromised patients presenting with optic neuropathy and retinal necrosis.
- Early diagnosis and appropriate antiviral therapy are essential to prevent irreversible vision loss and ocular complications in this vulnerable patient population.

Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
