Changes in the intraocular pressure in chronic liver diseases with ascites

The aim of the present work is to study changes in the intraocular pressure in cases having chronic liver diseases with ascites. Fifty patients suffering from chronic liver diseases with ascites and 12 non ascitic patients as a control were studied. Careful history, thorough clinical examination, laboratory, ultrasono-graphic and endoscopic investigations were performed for every patient and contro1. The intrao-cular pressure was measured by Schiotz indentation tonometer and confirmed by hand held applanation tonometer in 3 different sittings. There was no significant difference in the mean intraocular pressure between ascitic patients and non-ascitic controls. There was positive statistical correlation between the degree of portal hypertension as manifested by congestive splenomegaly and the intraocular pressure in 38patients. The lowest intraocular pressure measurements were found in 14 patients with blood urea ranging from 68 - 152 mg. This may be explained by the osmotic effect of urea on aqueous outflow present in patients with chronic liver diseases and ascites who are prone to develop functional renal failure. There was a significant decrease in the intraocular pressure in ascitic patients after diuretic therapy when compared to values before therapy

Effect of bromhexine on dry eye

A great immunological resemblance exists between the external eye and respiratory tract. Dryness lowers ocular resistance. Bromhexine gave excellent results in combating chest infection through augmentation of amount of bronchial secretion, being a bronchial mucolytic drug. We used bromhexine in treating dryness caused by Sjogren's syndrome and trachomatous cicatrisation in 100 eyes. Bromhexine proved to be effective in the majority of cases, but of very short duration. Cases were diagnosed and followed by quantitative rose bengal, and affirmed by Shirmer's test and B.U.T.

Effects of open heart surgery on intra ocular pressure [IOP]

The intra ocular pressure in both eyes of 23 patients undergoing open heart surgery, was measured by Schiotz indentation tonometer before, during and after the surgery until it returned to the pre operative levels. It was observed that a marked and rapid drop of the IOP occurs during the operation time, reaching its minimum during the cardio-pulmonary by-pass [[PB] period, then it gradually rises to its normal pre operative levels in 69.5% of cases [16 out of 23] at the end of the first post operative day, in 91% of cases [21 out of 23] at the end of the second post operative day and in all cases [100% of cases] at the end of the third post operative day. The possible explanations for such changes were discussed in view of the anaesthetic agents, techniques and associated hemodynamic parameters

Yag laser anterior capsulotomy

Planned extracapslar cataract extraction was done for different types of senile cataract, to study the role of Nd-YAG laser in anterior capsulotomy. As a result of this work is proved that YAG laser is a safe and satisfactory method for anterior capsulotomy

Evaluation of adhesive N-butyl-2-cyanoacrylate for recurrent pterygium

The study was carried on 40 surgeries which were done for recurrent pterygium. The following different techniques of N-butyle-2-cyanoacrylate application were used a. Limbo-scleral for 15 eyes b. scleral application for 15 eyes. C. No adhesive substance was used in the last 10 eyes as a control. The recurrence rate was high in the cases in which we did not use the adhesive substance. With the adhesive substance the incidence of recurrence was less with the cases of multiple application technique and for 14 days duration

adhesive substance in pterygium surgery

Different techniques of n-butyl-2-cyanoacrylate monomer application were done for 50 pterygium surgery. It was corneo-limbal in 10 eyes, Limbal in 10, Limbo-scleral in 10 and scleral in 10 eyes. No adhesive substance was used in the last 10 eyes, as a control. We have obtained favourable results with the adhesive substance, it is proved that it is quite safe and satisfactory as regards the low incidence of recurrence

Corneal astigmatism after glaucoma surgery

Different techniques of subscleral trabeculectomies were done, using different shapes of scleral flaps, in comparison with peripheral iridectomy, and iridenecliesis to study the incidence of postoperative astigmatism, in glaucoma surgery. The incidence of corneal astigmatism was lower in peripheral iridectomy and subscleral trabecuIectomies, specially triangular flaps, in comparison with iridencleisis

Comparison between trephine, punch and no 15 bard parker knife subscleral trabeculectomies

Under a traingular scleral flap, 66 trabeculectomies were done using; Trephine, punch and No 15 Bard-Parker knife. Each technique was used for 22 eyes. Trepanotrabeculectomy proved to be quite safe and satisfactory, all that was needed was a sharp trephine, and some experience as regards its use. The success rate was high and the complications were few
