Rhegmatogenous Retinal Detachment Assignment Sample
The following assignment sample work shall highlight the condition of (RRD) Rhegmatogenous Retinal Detachment, symptoms of the retinal detachment, and diagnosis and treatments of RRD condition.
Retinal detachment is described as an emergency situation in which the retina tissue at the back of the eye gets pulled away from it’s normal position. Layer of blood vessels responsible for providing nourishment and oxygen for the eyes gets seperated from retinal cells. Such displacement of retina can even cause a permanent loss of vision.
There are mainly three causes of retina detachment and they are tractional, exudative and rhegmatogenous. This is a very common condition among the people who have a family history of retina detachment, middle aged, previous eye surgery or any severe eye disease and injury.
In this assignment sample we will discuss the Rhegmatogenous Retinal Detachment in details.
Condition of Rhegmatogenous Retinal Detachment
Rhegmatogenous is a common type of retinal detachment which is caused due to a tear in the retina that allows the fluid to pass through and get collected under the retina which pulls away retina from underlying tissue. When the blood supply gets restricted into the area of detached retina it can lead to a situation of permanent loss of vision.
The most common cause of this condition is considered to be the age. It is the seperation of the neurosensory retina from retinal pigment epithilium through fluid transversing from vitreous cavity into subretinal space.
Symptoms of Retinal Detachment
There are many and definite signs of a retinal detachment in person but are clearly only visible when such condition gets into advanced stage. The common symptoms or signs of retinal detachment are :-
- Flashes of light in one or both the eyes.
- Blurred vision.
- Shadowed vision on the eyes.
- Sudden appearance of floaters and tiny specks drifting the field of vision.
- Gradual reduced side (peripheral) vision.
Diagnose and Treatments of Rhegmatogenous Retinal Detachment
Since the detachment is unpredictable and can vary it’s timings but if tears are caught early then it can be treated with a laser in a clinical setting. If once the rhegmatogenous retinal detachment is developed surgical intervention gets necessary.
When a patient visits an eye care specialist the retinal detachment gets easily detected by him. An asymptomatic retinal detachment are temporal detachments arising from the tears.
In symptomatology process there is a collection of symptoms which is closely studied by the specialist to diagnose the issue. There are many causes of RRD where the patients is not able to notice flashes if they are asleep so the unilateral loss of vision is ignored and detachment is noticed on getting blurred central vision.
Floaters are common symptoms of this condition for all the age group. There will be complaints of flashes, floaters or negative dyschromatopsia where these symptoms are associated with the RRD.
Negative dyschromatopsia may cause flashes and loss of vision and decrease in peripheral and central vision. After the study of such collective symptoms the clinician can refer the patient to an eye specialist.
The other way of detecting the condition of rhegmatogenous retinal detachment can be done with the help of clinical evaluation. A macula involving retina detachment is easy to identify and spot but a peripheral detachment cannot be easily detected.
Any clue of subretinal fluid or retinal break can be an immediate sign of reference to a doctor before visiting any such specialist.
If the clinical evaluation does not come out to be successful in detection of retinal detachment then three major contact lens examination and scleral depression can help in detection of peripheral tears. Vitreous hemmorhage or pigment cells in the vitreous can increase the risk of retina detachment.
In such cases an ultrasonography or vitrectomy is required and any careful examination can detect PVD or vitreous hemmorrhage causing the break in retina. There might be other conditions as well that may arise such as neoplastic disease, tractional retina detachment and inflammation.
Auxiliary testing is considered to be an effective technique to diagnose the RRD condition with the help of dilated fundus exam. These tests helps in identifying severity of retinal abnormalities. Widefield photography can help with scanning RRD.
Optical Coherence Tomography (OCT) in the widefield mode is very helpful in diagnose of RRD and can assess the macular status at the time of diagnosis. Using B-scan ultrasound is recommended only when there is no clear clinical view must be done in presence of media opacification.
In few cases the Fluorescein Angiography and Visual Field Testing can also be used for the diagnose of RRD.
Laser Treatments and Pneumatic Retinopexy
Laser treatments are effective only in those regions where the neurosensory retina and RPE can be brought together through scleral depression. Laser is applied to the border of detached retina.
All other retinal defects can be treated through laser. Prophylactic retinopexy is a low risk treatment for a person with this condition.
Pneumatic retinopexy can be used as the best treatment of RD where the retina break is located if more than one bubble exist they are localised in such a way so that the expansive bubble can adequately cover them with proper position of the patient.
Retinopexy can be performed by cryotherapy by applying laser to the breaks in prior to gas injection which is performed after several hours or days once the retina gets attached.
