Introduction

• separation of the choroid from the sclera

Etiology

• surgery (most common)
• trauma
• panretinal photocoagulation
• corneal ulcers
• globe hypotony ( serous)
• ocular inflammation ( serous)

Pathology

• serous:

• transudative fluid accumulation in the potential suprachoroidal space

• hemorrhagic:

• hemorrhage in the suprachoroidal space or within the choroid caused by the rupture of choroidal vessels

• separation of the choroid from the sclera

Clinical-manifestations

• spontaneous ( serous)

• generally painless
• variable visual impairment

• post surgical ( hemorrhagic):

• sudden excruciating throbbing pain
• immediate loss of vision

Diagnostic-procedures

• B-scan ultrasonography
• tonometry for intraocular pressure

Complications

• retinal detachment
• maculopathy
• globe phthisis
• visual impairment (40%)

Differential-diagnosis

• acute angle-closure glaucoma
• ocular melanoma
• pupillary block
• retinal detachment

Management

• topical corticosteroids
• cycloplegics
• mydriatics
• oral steroids may be indicated for ocular inflammation
• lower intraocular pressure if elevated

• acetazolamide ( carbonic anhydrase inhibitor)
• timolol
• mannitol
• parasympathomimetics are contraindicated
