Retinal detachment:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
Initially, the patient may complain of floating spots and recurrent flashes of light (photopsia). However, as detachment progresses, gradual, painless vision loss may be described as a veil, curtain, or cobweb that eliminates a portion of the visual field.

Vascular retinopathies:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
Central retinal artery occlusion produces sudden, painless, unilateral loss of vision (partial or complete). It may follow amaurosis fugax or transient episodes of unilateral loss of vision lasting from a few seconds to minutes, probably due to vasospasm. This condition typically causes permanent blindness. However, some patients experience spontaneous resolution within hours and regain partial vision.
Central retinal vein occlusion causes reduced visual acuity, allowing perception of only hand movement and light. This condition is painless, except when it results in secondary neovascular glaucoma (uncontrolled proliferation of weak blood vessels). The prognosis is poor — some patients with this condition develop secondary glaucoma within 3 to 4 months after occlusion.
Nonproliferative diabetic retinopathy produces changes in the lining of the retinal blood vessels that cause the vessels to leak plasma or fatty substances, which decrease or block blood flow (nonperfusion) within the retina. This disorder may also produce microaneurysms and small hemorrhages. Nonproliferative retinopathy causes no symptoms in some patients; in others, leakage of fluid into the macular region causes significant loss of central visual acuity (necessary for reading and driving) and diminished night vision.
Proliferative diabetic retinopathy produces fragile new blood vessels on the disk (neovascularization) and elsewhere in the fundus. These vessels can grow into the vitreous and then rupture, causing vitreous hemorrhage with corresponding sudden vision loss. Scar tissue that may form along the new blood vessels can pull on the retina, causing it to tear or even detach.
Symptoms of hypertensive retinopathy include blurred vision, often accompanied by headache. Ophthalmoscopic examination may reveal diffuse binocular narrowing, venular tortuosity, silver wire reflexes, macular stars, and swelling of the head of the optic nerve (disk edema). Severe, prolonged disease eventually produces blindness; mild, prolonged disease, visual defects.
Symptoms of sickle cell retinopathy include peripheral arteriolar occlusions, peripheral arteriovenous anastomoses, sea fan neurovascular fronds, vitreous hemorrhage as tractional forces and vitreous collapse tear fragile neovascular membranes and, with advanced disease, severe vitreous traction and retinal detachment.

Vascular retinopathies:
Signs and symptoms
(Handbook of Diseases)
The following features characterize vascular retinopathy.
Central retinal artery occlusion
This type of occlusion produces sudden, painless, unilateral loss of vision (partial or complete). It may follow amaurosis fugax or transient episodes of unilateral loss of vision lasting from a few seconds to minutes, probably due to vasospasm.
This condition typically causes permanent loss of vision. However, some patients experience spontaneous resolution within hours and regain partial vision.
Central retinal vein occlusion
Occlusion of this type causes reduced visual acuity, allowing perception of only hand movement and light. This condition is painless, except when it results in secondary neovascular glaucoma (uncontrolled proliferation of weak blood vessels). Prognosis is poor — 5% to 20% of patients with this condition develop secondary glaucoma within 3 to 4 months after occlusion.
Diabetic retinopathy
Nonproliferative diabetic retinopathy produces changes in the lining of the retinal blood vessels that cause the vessels to leak plasma or fatty substances, which decrease or block blood flow (nonperfusion) within the retina. This disorder may also produce microaneurysms and small hemorrhages.
Although nonproliferative retinopathy causes no symptoms in some patients, in others fluid leakage into the macular region causes significant loss of central visual acuity (necessary for reading and driving) and diminished night vision.
Proliferative diabetic retinopathy produces fragile new blood vessels on the disk and elsewhere in the fundus (neovascularization). These vessels can grow into the vitreous and then rupture, causing vitreous hemorrhage with corresponding sudden vision loss.
Scar tissue that may form along the new blood vessels can pull on the retina, causing macular distortion and even retinal detachment.
Hypertensive retinopathy
Symptoms of hypertensive retinopathy depend on the location of retinopathy. For example, mild visual disturbances such as blurred vision result from retinopathy located near the macula.
Without treatment, the prognosis is poor (50% of patients become blind within 5 years). With treatment, the prognosis varies with the severity of the disorder. Severe, prolonged disease eventually produces blindness; mild, prolonged disease, visual defects.
