Ocular findings among foundry workers

This study was carried out on 75 workers in a foundy in Zagazig city, Sharkia governorate and on a control group of 20 subjects in the administration section in the same foundary. The study revealed that there was a higher prevalence of conjunctival pigmentation [40 percent], cojunctival irritation [28 percent], pinguecula [20 percent] and pterygium [33.3 percent] among exposed workers than in their corneal group [5 percent, 15 percent, 10 percent and 10 percent, respectively]. Also, control foreign bodies, corneal opacities and lenticular changes were of a higher prevalence among exposed workers [5.3 percent, 20 percent and 6.7 percent respectively] than in non-exposed subjects [0 percent, 5 percent and 0 percent, respectively]. The duration of exposure is considered as a risk factor in prevalence of ocular hazards

Traditional versus modified trabeculectomy in primary open angle glaucoma

Two groups of primary open angle glaucoma patients, each of 50 patients, were undergone trabeculectomy. In the first group, [59 eyes], traditional trabeculectomy-where the excised internal corneo-scleral block almost reached the edges of the scleral flap-was performed. The second group [68 eyes], were undergone a modified trabeculectomy. Where internal corneo-sclectomy stopped 1 mm short the edgs of the covering scleral flap i.e., leaving a ledge of 1mm. Cases of either group were followed up for 8-10 months for postoperative complications and intraocular pressure [10P] control. It was found that; modified trabeculectomy was associated with a significantly lower incidence of postoperative shallow or flat chamber and their sequences. Both procedures were effective regarding postoperative intra-ocular pressure control with insignificant difference

Evaluation of conjunctival flaps in resistant corneal ulcers

Different types of conjunctival flaps were performed for 39 cases with resistant corneal ulcerations. Total flaps were 1 for large central corneal ulcers [23 cases], bridge flaps for small central or paracentral ulcers [11 cases] and peripheral flaps for marginal small ulcers [5 cases]. All the cases showed complete healing in 5-10-14 days whatever the cause and duration of resistant ulcers or the time of flap recession

Conjunctival autograft for recurrent pterygiumy

Thirty-eight eyes of 32 patients with recurrent pterygium were included in this study. They were divided into two groups. 18 eyes were treated by simple excision, followed by Beta irradiation [control group]. The remaining 20 eyes were treated by excision and conjunctival autograft transplantation. The cases were followed up for 6 months. The first group gave a recurrence rate of [16%], while cases treated with conjunctival autograft gave a minimal recurrence rate of [5%]. These results were tabulated, illustrated and discussed
