Retinal detachment is an emergency eye condition in which the retina at the back of the eye gets separated from the surrounding tissue and pulls away from its normal position. The retina acts as a light-sensitive wallpaper in the eye, providing a lining for the inside of the eye wall and sending visual signals to the brain. As the retina can't work properly under these conditions, one can permanently lose vision if the detached retina is not repaired immediately.
During the retinal detachment, the retinal cells gets separated from the layer of blood vessels which provides oxygen and nourishment. Usually, it begins in form of small torn area of retina known as retinal tears or retinal breaks. This condition, if not treated, leads to retinal detachment and finally permanent vision loss.
Retinal detachment has tell-tale warning signs like an increase in sudden appearance of floaters resembling cobwebs floating in field of vision. It can be coupled with flashes of light or curtain from any direction causing a loss of vision.
Retinal detachment is of three types
1. The most common form is Rhegmatogenous retinal detachment where a tear allows fluid to get under retina and prevents nourishment to reach retina from retinal pigment epithelium by separating them.
2. In Tractional form, scar tissue on the retina's surface shrinks causing it to separate from the retinal pigment epithelium. This form is most prevalent with diabetes patients.
3. Lastly, in case of Exudative retinal detachment, the fluid leaks into the area under retina without a tear or breaks in the retina. Retinal diseases or trauma to the eye are main causes for Exudative retinal detachment.
Although a person of any age can suffer from retinal detachment, but it is more prevalent in people over the age of 40. People suffering from degenerative myopia or lattice degeneration are more prone to this medical condition. People with family history of retinal detachment are also likely to suffer from the same.
Retinal detachment can be treated in many ways. The most common form is the Laser surgery in which small tears and hole are joined back to the retina. Another method is Cryopexy in which the area around the hole in frozen and helps reattach the retina. Both the above procedure are performed at ophthalmologist's clinic.
Sometimes, one may have to opt for Scleral buckle in which a tiny synthetic band is attached to the outside of the eyeball which gently pushes the wall of the eye in toward the centre of the eye placing the eye wall very close to the detached retina. Another option is vitrectomy surgery to replace the vitreous that fills the centre of the eye and helps the eye maintain a round shape.
A retinal detachment is an emergency medical condition and must be treated immediately to save one's vision. Most people have been successfully treated for retinal detachment, but ophthalmologists cannot always predict how vision will turn out. The visual outcome will not be known for up to several months after surgery. However the results are best when the retinal detachment is treated as soon as possible. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.
It is very essential in the present times to understand the training, ability and skills of the doctors whom you select for your needs.
An Eye Doctor is called an Ophthalmologist. He/she can possess following qualifications
M.S (Ophth) : This is called Master Of Surgery in Ophthalmology. It takes Three years of training in a Medical Council recognized Medical College after passing M.B;B.S and includes undertaking and submission of a thesis or research Paper during the training. It can be done by obtaining seat based on Merit, Based on reservation or Based on Donation
D.O (Ophth) : This is called Diploma in Ophthalmology. It is similar to M.S. except that training period is TWO years and does NOT include doing research paper
DNB (Ophth): This is called Diplomat of National Board in ophthalmology. The training is done after M.B;B.S in some private institutes or hospitals recognized by National board of examinations and not in MCI recognized Medical college
Long Term Fellowships: As the knowledge base is increasing, there is further training undertaken for super specializing in some specific field of eye surgery through a process called FELLOWSHIP. This includes training for about two years after M.S., D.O or D.N.B in some Institues of repute like Shankar Nethralaya Chennai, Aravind Eye Care Systems ( Madurai/ Coimbatore), L.V.Prasad Eye Institute ( Hyderabad) to name a few. The training involves doing actual work in specialized techniques under supervision and guidance of experts in respective fields like Retina, Cornea, Glaucoma, Oculoplasty, Phaco and Refractive Surgery, Paediatric Ophthalmology, Neurophthalmology etc.
Short Term Fellowships: They are similar to long term fellowships but training period is very short , like 2-3 months . The training helps a general ophthalmologist to acquire some skills in a speciality but not sufficient to be able to be a super specialist. However, some doctors with such training may claim to be superspecialists!
ACEDEMIC FELLOWSHIPS: Such fellowships test the knowledge of Doctor through two or three steps of examinations/ Viva. There is no practical training given Examples are,
FRCS: Fellow of Royal College of Surgeons
FICO: Fellow of International Council of Ophthalmologists
FAICO: Fellow of All India Collegium of Ophthalmologists
Some senior Ophthalmologists who were trained in multiple eye diseases and worked for a long time in handling them may be as good as superspecialists in some areas.
Besides Ophthalmologists, some trained personnel can undertake some eye care tasks like
Optometrists: They can assess and prescribe Spectacle power(numbers), prescribe and dispense contact lenses, run some eye tests on machines.
Opticians: They can make/ sell glasses or contact lenses as prescribed by Ophthalmologists/ optometrists. They can not prescribe. Yet, many shops do so without Optometrists.
Ophthalmic Technicians: They can operate machines like Perimetry, OCT, A scan ultrasonography, Topography etc.
Hope that now the readers are better informed about their eye care providers. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.
