RETINAL DETACHMENT Mohammed Al-Khaldi MPH 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 1

RD related Epidemiological facts • The incidence of RD in otherwise normal eyes is around 5 new cases in 100,000 persons per year. • RD is more frequent in middle-aged or elderly, with rates of around 20 in 100,000 per year, and the lifetime risk in normal individuals is about 1 in 300. • RD is more common in people with severe myopia (above 5–6 diopters), in whom the retina is more thinly stretched. In such patients, lifetime risk rises to 1 in 20. • About two-thirds of cases of RD occur in myopics. Myopic retinal detachment patients tend to be younger than non-myopic ones. 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 2

Contd, RD related Epidemiological facts • RD is more frequent after surgery for cataracts. The estimated long-term prevalence of RD after cataract surgery is in the range of 5 to 16 per 1000 cataract operations, but is much higher in patients who are highly myopic, with a prevalence of up to 7% being reported in one study. • A study found that the probability of experiencing retinal detachment within 10 years of cataract surgery may be about 5 times higher than in the absence of treatment. • Although RD usually occurs in just one eye, there is a 15% chance of it developing in the other eye, and this risk increases to 25–30% in patients who have had a retinal detachment and cataracts extracted from both eyes. 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 3

RETINA • light-sensitive layer of tissue • sends visual messages through the optic nerve 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 4

• pulled away from the underlying choroid • small areas of the retina torn => retinal tears or retinal breaks • retinal cells deprived of oxygen • if not promptly treated => permanent vision loss 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 5

SYMPTOMS • floaters - bits of debris in field of vision that look like spots, hairs or strings 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 7

02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 8

SYMPTOMS • floaters • light flashes • shadow or curtain over a portion of visual field • blur in vision 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 9

Can occur as a result of: • trauma • advanced diabetes • an inflammatory disorder, such as sarcoidosis • shrinkage of the jelly-like vitreous that fills the inside of the eye 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 10

• vitreous liquid leaks through retinal tear and accumulates underneath retina • retina can peel away from underlying layer of blood vessels 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 11

Factors that may increase risk of retinal detachment • • • • • • aging - more common in people older than 40 previous retinal detachment in one eye family history of retinal detachment extreme nearsightedness previous eye surgery previous severe eye injury or trauma 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 12

TREATMENTS Retinal tears: • laser surgery (photocoagulation) • freezing (cryopexy) Retinal detachment: • pneumatic retinopexy • scleral buckling • vitrectomy 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 13

PHOTOCOAGULATION 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 14

VITRECTOMY 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 19

When a surgeon injects a bubble of expandable gas into the vitreous cavity it is called: • • • • • scleral buckling vitrectomy pneumatic retinopexy photocoagulation cryopexy 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 20

Important hint related to the results of surgery 85 % of the cases dealt with successfully in a single operation with 15 % of the remaining cases need to be two or more. After treatment, patients regain their vision therapists gradually over a period of a few weeks, despite the fact that visual acuity may not be as good as it was before the detachment, especially if the spot included in the detachment. 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 21

Retinal detachment can occur as a result of; •Obesity •Trauma •Nearsightedness 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 22

When a surgeon uses intense cold to freeze the retina around the retinal tear it is called; • Scleral buckling • Vitrectomy • Pneumatic retinopexy • Photocoagulation • Cryopexy 02/15/14 Retinal Detachment, Mohammed Al-Khali, 2014, St John Eye Hospital. 23
