Summary
Acute macular neuroretinopathy (AMNR) is a rare visual disorder. This case highlights phenylephrine use and flu-like illness as potential triggers for AMNR in young women.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Neuro-ophthalmology
Background:
- Acute macular neuroretinopathy (AMNR) is a rare condition causing sudden vision loss.
- Its pathophysiology is not fully understood, but associations with viral illness and vasoconstrictors exist.
Observation:
- A case of AMNR in an 18-year-old female with bilateral central vision blurring.
- Symptoms followed a flu-like illness and a week of phenylephrine hydrochloride use.
- The patient presented with characteristic optical coherence tomography findings and rare acute ophthalmoscopic features.
Findings:
- The case report details the clinical presentation and diagnostic findings of AMNR.
- It associates phenylephrine hydrochloride, a common vasoconstrictor, with the onset of AMNR.
- Rarely observed acute ophthalmoscopic features were documented.
Implications:
- This case provides further insight into the potential pathophysiology of AMNR.
- It suggests a possible link between vasoconstrictor use, specifically phenylephrine, and AMNR development.
- Understanding these triggers can aid in early diagnosis and management of AMNR.

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...
01:20Anatomy 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,...
