2.  It is a condition in which the retina gets separated from its place  It can cause sudden and painless drastic loss of vision  It can be of different types and due to various causes Retinal detachment

3.   Diabetic Retinopathy   High Myopia   Traumatic Causes

4.  Flashes of light  Floaters  Visual field defect  Sudden loss of vision Symptoms

5. 1. Flashes of light Patient can see flashes of light especially during eye movements, blinking, this is due to pull on the detached retina 2. Floaters Small black spots, cobweb-like or large black rings may be seen by the patient 3. Visual field defect It is perceived by the patient as a black curtain before his eye 4. Sudden loss of vision This can be due to retinal detachment involving the macula The prognosis is very poor if the macula is involved

6. Diagnosis   Tractional retinal detachment (D.R)   Executive retinal (Traumatic)   Rhegmentogenous (Myopia)

7. Treatment: Treatment of RD is essentially surgical and should be done immediately once diagnosed Surgery: Surgery for retinal detachment involves three major steps Scleral buckling (SB) A band or sponge made up of silicone material is sutured firmly to the sclera to close the hole in the retina Cont…

8. Vitrectomy: Removal of the vitreous humour is done to relieve bands which may pull the retina and to enable the surgeon to repair the retina Silicone oil injection or C3F8 gas injection:  After vitrectomy the empty vitreous cavity has to be filled with silicone oil or with C3F8 gas injection  Patient must undergo another surgery for removal of silicon oil after 3-4 months  Only after silicone oil removal patient can see better Cont…

9. Disadvantages:  If the silicone oil is not removed within 3-4 months, patient can develop cataract, and or glaucoma and may occasionally experience double vision

10. In C 3 F 8 In C 3 F 8  In case of C 3 F 8, there is no need for removal as it is a gas, hence a second surgery is not needed  The gas gets absorbed over 11/2 months  During this period patient might experience floaters prognosis
