Differential Diagnosis for Small Red Bumps on Conjunctiva with Hemorrhage and Vision Changes
Single Most Likely Diagnosis
- Acute Angle-Closure Glaucoma: This condition is characterized by sudden increased intraocular pressure, which can cause small red bumps on the conjunctiva (inflammatory signs), hemorrhages, and significant vision changes, including blurred vision and seeing halos around lights. The acute onset and combination of symptoms make this a highly plausible diagnosis.
Other Likely Diagnoses
- Conjunctivitis: Especially if caused by an allergic reaction, a bacterial infection, or a viral infection, conjunctivitis can present with red bumps, discharge, and irritation. While vision changes are less common, significant inflammation can affect vision.
- Keratitis: Inflammation of the cornea can cause redness, pain, and vision changes. If the keratitis is severe, it might also lead to hemorrhages within the eye.
- Uveitis: Inflammation of the uvea, which includes the iris, ciliary body, and choroid, can cause eye pain, redness, sensitivity to light, and vision changes. Hemorrhage can occur in severe cases.
Do Not Miss Diagnoses
- Endophthalmitis: A severe infection within the eye that can cause pain, redness, decreased vision, and in severe cases, hemorrhage. It is a medical emergency.
- Retinal Detachment: Although it might not directly cause small red bumps, it can lead to sudden vision changes, including flashes of light and floaters, and is an emergency.
- Central Retinal Artery Occlusion: Sudden loss of vision in one eye, which might be accompanied by other symptoms like redness and pain, is a medical emergency requiring immediate attention.
Rare Diagnoses
- Sarcoidosis: A systemic disease that can affect the eyes, causing uveitis, conjunctivitis, and other ocular symptoms, including vision changes.
- Behçet's Disease: A form of vasculitis that can cause a wide range of symptoms, including oral and genital ulcers, skin lesions, and eye inflammation, which might present with the described symptoms.
- Eale Disease: A rare disease characterized by recurring retinal and vitreal hemorrhages, often associated with vision loss, which might also present with inflammatory signs in the conjunctiva.
