Complications of retinal capillary haemangioma

Leakage

Exudative retinal detachment

Hard exudate formation Epiretinal membrane formation

Treatment options of retinal capillary haemangioma

•Argon laser photocoagulation - small peripheral tumours

•Cryotherapy - larger peripheral tumours

•External beam radiotherapy - if unresponsive to cryotherapy


Before treatment - dilated feeder	Following treatment - normal
vessels	feeder vessels

Systemic features of Sturge-Weber syndrome

Naevus flammeus

Meningeal haemangioma

•	Congenital, does not blanche	•	CT scan showing left
	with pressure		parietal haemangioma
•	Associated with ipsilateral	•	Complications - mental handicap,
	glaucoma in 30% of cases		epilepsy and hemiparesis

Glaucoma

Buphthalmos in 60% May be associated with episcleral haemangioma

Diffuse choroidal haemangioma


Normal eye	Affected eye

TRAUMA

1.Eyelid

•Haematoma

•Floor

•Medial wall

3.Complications of blunt trauma

•Anterior segment

•Posterior segment

4.Complications of penetrating trauma

5.Management of intraocular foreign bodies

6.Chemical injuries

Eyelid haematoma

Usually innocuous but exclude associated trauma to globe or orbit


Orbital roof fracture if associated with	Basal skull fracture - bilateral ring
subconjunctival haemorrhage without	haematomas (‘panda eyes’)
visible posterior limit

Lid margin laceration

Carefully align to prevent notching

Align with 6-0 black silk	Close tarsal plate with
suture	fine absorbable suture

Place additional marginal	Close skin with multiple
silk sutures	interrupted 6-0 black
	silk sutures

Canalicular laceration


• Repair within 24 hours	• Locate and approximate ends of laceration
	•	Bridge defect with silicone tubing
	•	Leave IN SITU for about 3 months

Pathogenesis of orbital floor blow-out fracture

Signs of orbital floor blow-out fracture

•Periocular ecchymosis and oedema

•Infraorbital nerve anaesthesia

• Ophthalmoplegia -	• Enophthalmos - if severe
typically in upand down-
