effect of different techniques on the results of argon laser trabeculoplasty

Patients with uncontrolled open-angle glaucoma on maximal tolerable treatment were treated with argon laser to the trabecular meshwork. Forty eyes [30 patients - 10 patients had bilateral open angle glaucoma]. These patients were divided into 4 groups. The technique of argon laser therapy is different in each group of eyes. Follow up of intraocular pressure and field changes for 6 months for each group was performed to compare between various techniques

Limitations of silicone oil in vitreous surgery

Thirty five cases of complicated retinal detachment, such as giant retinal tears, advanced proliferative vitreo-retinopathy, recurrent retinal detachment, posterior retinal breaks and diabetic tractional and rhegmatogenous retinal detachment, were operated upon; by modem vitreo-retinal surgery and liquid silicone injection. An anatomical reposition was attained in 95% of cases. Useful vision was reached in 55%, while ambulatory vision was reached in 40%. Complications were few over a period of one year. Advantages, disadvantages, limitations and rationale of the use of liquid silicone are discussed

comparative study of computerised automated versus manual perimetry

One thousand and foully manual and automated visual fields have been studied and analyzed. Eight hundred and ten manual kinetic visual fields were performed on the Goldmann projection perimeter and the B. and L. Tangent Autoplot perimeter; while two hundred and thirty tests were conducted using the Dicon 200 computerised autoperimeter. One hundred and eighty fields were conducted on patients using both manual and automated perimetry at the same sitting. It was found that reliable reproducable field could be obtained with computerised perimetry in an accurate way, highly comparable to the standared manual perimetry
