Posterior Vitreous Detachment (PVD): This is a common condition where the vitreous gel separates from the retina, often causing retinal tears or detachments. It is a leading cause of retinal detachment in non-diabetic patients, especially those over 50 years old.

Trauma: Blunt or penetrating eye injuries can cause retinal detachment by creating tears or holes in the retina.
Retinal Tears: Tears in the retina can lead to retinal detachment if left untreated. They can occur spontaneously or as a result of trauma.
High Myopia: Patients with high myopia are at increased risk of retinal detachment due to the thinning and stretching of the retina.
Retinal Holes: Similar to retinal tears, retinal holes can allow fluid to seep underneath the retina, causing detachment.

Malignant Melanoma: Although rare, malignant melanoma of the eye can cause retinal detachment. Missing this diagnosis could be fatal.
Central Serous Chorioretinopathy: This condition involves fluid accumulation under the retina, which can mimic retinal detachment. It is usually benign but can cause significant vision loss if not treated.
Uveitis: Inflammatory conditions like uveitis can cause retinal detachment, and missing this diagnosis could lead to severe vision loss and other complications.

Stickler Syndrome: A genetic disorder that affects the connective tissue, including the retina, and can cause retinal detachment.
Ehlers-Danlos Syndrome: A group of genetic disorders that affect connective tissue, which can increase the risk of retinal detachment.
Marfan Syndrome: A genetic disorder that affects the body's connective tissue, including the eyes, and can increase the risk of retinal detachment.
Sickle Cell Disease: Although more commonly associated with diabetic retinopathy, sickle cell disease can cause retinal detachment in non-diabetic patients due to sickling of red blood cells in the retinal vessels.
