CHANDIGARH, Jan 29 — With  latest techniques available, phacoemulsification of white cataract is now possible. Talking to Chandigarh Tribune,  during the annual conference of the Chandigarh Ophthalmological Society here yesterday, Dr Jagat Ram, Additional Professor, Ophthalmology Department,  PGI, said this technique, to which the world was recently introduced in the year 2000, is now also  available  in the institute.  
Phacoemulsification involves a small incision of 3 mm on  cornea. Following ultrasonic emulsification of the cataract, a foldable intraocular lens is implanted.  
According to Dr Jagat Ram, in India, 25 per cent of cataract cases, especially from rural areas, come to the hospitals at a very advanced  stage.
The  conventional techniques of  correcting cataract required  a big incision, involving 5 to 7 sutures and long stay in hospital. In the phacoemulsification technique, no suture is required and the person becomes mobile the same day. 
This technique, however, is best applicable when cataract is  noticed at an early stage. The later-stage treatment, besides being difficult for the surgeon, may also not give very good results. 
As per Dr Jagat Ram, last year an extension of the phacoemulsification technique was developed whereby dyes called trypan blue or indosynin green are injected  into the anterior chamber. This stains the opaque chamber and the white margins of the cataract are clarified, thereby making it possible for the surgeon to visualise the entire process of phacoemulsification. Moreover, clinical studies also reveal that  the dye does not have any toxic effect on the patient.
The focus of the one-day symposium was diabetic retinopathy.  While Dr B Patnaik from Delhi gave an introduction to the epidemiology and pathology of the disease, Prof Amod Gupta, Head, Ophthalmology Department, PGI, presented the role of vitreous surgery in the condition.
Dr M.R. Dogra, Associate Professor, Ophthalmology Department, PGI, talked about the role of  laser surgery in correcting the disease. According to Dr Dogra, diabetic retinopathy is the major emerging cause for blindness in the country with 5 to 8 per cent people in the country suffering from diabetes. 
As per Dr Dogra, awareness  in  both patients and doctors is also important because unlike  cataract surgery, treatment for diabetic retinopathy is very expensive.  While the  earlier stages require a treatment with laser, advanced cases have to be treated with the more complicated vitreous surgery. While cataract surgery is commonly available, laser and vitreous surgeries are expensive and are also  not available in most of the health institutions of the country.
A strict control of diabetes  has shown that it delays the onset of retinopathy and cuts down its progression, said Dr Dogra. It is a multi-system disorder which affects the blood vessels in the body. In eyes, during the early stages, blood, fats and fluids start leaking. Later this develops into abnormal blood vessels, leading to massive haemorrhage  and subsequent  blindness.
Dr B. Patnaik, President, Delhi Ophthalmology Society,  presented the Grover Memorial Oration on the “Eale’s disease, old disease, new outlook.” As per Dr Patnaik, the disease predominantly affects  young males in the age  group of 20 to 40. While its causes are not known, it is quite prevalent in India.
Experts attribute the causes for the disorder to the  presence of tuberculosis and other numerous  infectious diseases in the country. Why it predominantly affects males is not yet known.
As per Dr Ashok Sharma, Associate Professor, Ophthalmology Department,  PGI,  the patient suffers  repeated bleeding along the infectious blood vessels of the retina. The earliest indications include cobwebs or  small objects in front of the eyes and later a  complete loss of vision.  
As per Dr Patnaik, an early detection is  important as its management depends on the  stage at which the disease has been detected. While the initial stages can be treated with drugs  the  later stages have to be treated with laser. 
Other speakers included Dr S. Sood, Head Ophthalmology, GMCH, Dr S.S. Pandav, Dr Vaishali Gupta, Dr Anil Bhansali, Dr Sashi Kapoor, Dr S.P.S. Grewal, Dr Gagandeep Brar, Dr Subina Narang and Dr Rohit Kapoor.
