Microbiological study of the normal conjunctival flora and resistant cases of conjunctivitis

This study included 100 diabetic patients of these, 50 patients had normal conjunctiva and they were considered as control. Microbiological study was performed to find out their conjunctival flora. ln this work we almost did not find any signiflcant difference between the conjunctival flora of diabetic persons and that of non-diabetic cases.The other 50 patients were suffering from resistant conjunctivitis [receiving proper therapy for more than two weeks without sufficient response]. Conjunctival swabs from these patients were studied looking for the possible aeteological agents whether bacterial, fungal or viral. A correlation has been made between the microbiological findings and the clinical presentation of the patients

Electroretinographic evaluation of ocular complications following radiation therapy

An electroretinographic study has been performed, as a measure of retinal function, in a series of 60 patients who received telecobalt radiotherapy for tumours that involved the orbit or adjacent structures. Beside electroretinogram [ERG] recording, patients were subjected to complete ophthalmological examination before, immediately after and 6 months following treatment. In all the cases, ERGs. showed hyperactive responses immediately after irradiation but returned to the pre-irradiation levels within 6 months after treatment

Viral hemorrhagic conjunctivitis

500 cases with hemorrhagic conjunctivitis were examined clinically, and of these 50 cases were examined bacteriologically, and bacteria was excluded as a cause of this condition. Serological tests were done, and it was found that entrovirus is most probably the causative organism

Effect of argon laser photocoagulation on the electrooculogram of diabetic retinopathy patients

This study includes 17 patients having proliferative or advanced background diabetic retinopathy. 27 eyes underwent panretinal photocoagulation. Electro-oculorgram was done both before and after the laser treatment. An average reduction of about 23.1 percent in the pretreatment value of Arden Ratio was found. Arden Ratio above 155 percent was found in 55.7 percent of patients before treatment, and after treatment it was found in only 17.5 percent of patients. The damage induced by the photocoagulation to the retinal pigment epithelium and the overlying photoreceptors is most probably the cause of this reduction in the value of Arden Ratio

survey of some ophthalmic problems in hurghada

An organised survey of the inhabitants off Hurghada attending the outpatient clinic and of school children was carried out. Among the 300 outpatient clinic visitors, pterygium was searched for in adults and refractive errors in children below 15 years of age. Pterygium was found ion 5% of patients [15/300]. Of the 720 school children examined, a search for the different stages of trachoma and refractive errors was stressed upon. Two hundred and ninety two [292] children [40.56%] were affected with different stages off trachoma, while 112 [15.6%] had refractive errors. One hundred and thirty [130] persons were randomly selected to test for the incidence of toxoplasmosis, of them 15 persons [11.54%] gave positive results
