Behavior of intraocular pressure following different methods of cataract extraction

In this prospective study of 100 eyes of 97 consecutive patients, we attempted to detect differences in the course of intraocular pressure [IOP] after two main types of non-enzymatic cataract extraction: intracapsular extraction without alphachymotrypsin [30 eyes], and planned extracapsular extraction [70 eyes] with insertion of a posterior chamber intraocular lens without sodium hyaluronate [21 eyes]. IOP was measured with a non-contact applanation tonometer preoperatively and at specified intervals up to 3 months after surgery. No significant difference in IOP could be detected according to the types of cataract surgery. Transient ocular hypertension occurring within the first few postoperative days was seen in 59% of all eyes; there was no significant association with any parameter of the surgery. In contrast, a cause could often be found for the ocular hypotension that occurred in 11% of eyes in the first seven postoperative days. Late postoperative hypotension was recorded after the seventh postoperative day in 75% of all cases and persisted for an a verage of 4 weeks, a cause for this was rarely found. In 22% of all cases, IOP remained within normal limits [10 to 20 mmHg] throughout the postoperative period

Ocular findings in chronic renal failure

The ocular complications associated with chronic renal failure were studied in 100 patients. The study revealed that retinopathy was the commonest ocular finding [74 eyes], and conjunctival calcifications were the second in order of frequency [14 eyes]. Corneal calcifications were the third category [11 eyes], lenticular opacities were the fourth entity [8 eyes]. A review of literature and a comparison of the results were discussed

Keratometric changes after cataract extraction

This study includes 74 patients with senile cataract admitted to the ophthalmic department in Assiut University Hospital for cataract surgery. Preoperative evaluation of the patients were done with special attention to the cornea. Preoperative and postoperative keratometric readings were taken and the amount of the astigmatism was calculated and the axis of the astigmatism was determined by the Javal-Schiotz keratometer at one month, 2 months and 3 months after the operation. The keratometric changes in these cases were compared with the findings of other authors

Surgical management of rodent ulcer of the eyelids

A clinical study of 34 cases of rodent ulcer of the eyelids and adjacent skin was carried-our over a period of 4 years in the ophthalmic department of Assiut University Hospital. For the treatment of these cases, variable surgical techniques were performed and their results were compared with those of others

Incidence and causes of defective vision below 6/60 among the patients of the out-patient clinic of Assiut University Hospital

This paper shows that incidence of blindness is very high in upper Egypt. Most of the causes for blindness could be prevented, and if it is aptly said that prevention is better than cure, it is more particularly so in ophthalmology. Preventive measures save a lot both in treatable and non treatable diseases which are the leading causes for blindness. According to Jones 1978[3] there are obstacles to work for prevention of blindness. One of these obstacles is not having the will to act, this results from ignorance: ignorance of the existence, the importance, and the dimensions of the problem
