CF and AMG are effective in treatment-resistant infectious keratitis. They could restore ocular surface integrity and provide metabolic and mechanical support for corneal healing. For large corneal perforation, it may be better to use another procedure such as penetrating keratoplasty to restore ocular integrity.

Both preoperative MMC injection followed 1 day later by pterygium excision with CAG, and pterygium excision and intraoperative local application of MMC on the medial rectus tendon are successful in treating primary pterygium with low recurrence rate and few complications.

Objectives: The objective of this study is to estimate the prevalence of symptomatic suspected dry eye, diagnosed dry eye syndrome (DES), and associated risk factors; in Riyadh, Saudi Arabia. Methods: A cross-sectional study of 654 participants was employed using a self-administered semi-structured questionnaire that included demographic characteristics like age, gender, and risk factors (smoking, using contact lenses, chronic comorbidities, etc.). Results: There were 266 (40.7%) previously diagnosed DES participants and 388 (59.3%) non-diagnosed DES, of which 497 were female and 157 were male. Females had a significantly higher rate of diagnosed DES than males (p<0.001), with a significant increase in the rate of DES diagnosis with age (p<0.001). There was also a significant increase in DES in participants with diabetes mellitus, allergic eye, thyroid eye, and skin diseases, as well as having undergone laser surgery or using contact lenses. There was no significant increase in DES in cases of smoking, daily use of electronic devices, or duration of sleep. Conclusion: The prevalence of dry eye among adults in Riyadh was 46.6%, with the most important risk factors being female gender, increasing age, Lasik refractive surgery, skin disease around the eye, and thyroid eye disease.

BackgroundTo study the efficacy of the biodegradable collagen implant Ologen® as an adjuvant in phaco-viscocanalostomy in patients with coexisting cataract and primary open angle glaucoma.MethodsThis prospective, interventional, randomized clinical study was done at Alpha Vision Center, Zagazig, Egypt. Patients with coexisting cataract and glaucoma were randomized to receive either phaco-viscocanalostomy (Phacovisco group) (39 eyes) or phaco-viscocanalostomy with Ologen® implant (OloPhacovisco group) (40 eyes). Follow-up period was 2 years. Nd:YAG laser goniopuncture was done in cases where the intraocular pressure (IOP) was elevated above 21 mmHg after discontinuation of corticosteroid eye drops at any follow-up visit.ResultsNo significant operative or postoperative complications (other than failure) were encountered in either group. At 2 years follow-up, the mean IOP level was statistically significantly decreased in the OloPhacovisco group (p = 0.02) and complete success occurred in 23 eyes (59.0%) in the Phacovisco group and in 32 eyes (80.0%) in the OloPhacovisco group. There was a statistically significant higher success rate regarding complete success in patients that received Ologen® implant (p = 0.04).ConclusionsOlogen® implant improved the success rate of phaco-viscocanalostomy. Larger studies with longer follow-up periods may be required to confirm these findings.Trial registrationThis trial was retrospectively registered on 20/12/2018 under the number (NCT03782051).
