Alongside the use of face mask as a preventive measure during the COVID-19 pandemic, it has been noticed a high increase in chalazion incidence. Purpose: To determine whether or not using face mask is correlated to the rise in chalazion cases among patients. Material and Methods: This is a retrospective multicentric study, conducted in two different hospitals distanced by more than 500 Km (Rabat Military Hospital and Tetouan’s Provincial Hospital). Records of the operative rooms and medical visits of both centers were reviewed and patients with chalazion were included. We, then, determined the incidence of chalazion for each month between March and September of years 2018, 2019, 2020, 2021, and 2022. The data collected was then processed by the software Jamovi 22.0. Results: It is clear through our data analyses that the chalazion incidence rose in the pandemic period compared to the same month of the years 2018, 2021 and 2022. The risk of developing chalazia also increased with the frequent use of face mask daily. Conclusion: face mask wear appears to have a direct link to chalazion formation. To keep a safe balance between the protective role of face mask and its adverse effect on the ocular surface stability, many measure may be proposed and appear to be quite efficient.

Purpose: The aim of our study is to compare two different techniques for conjunctival autografting: surgical suturing and autologous blood coagulum. Methods: In this prospective study, we randomly divided 30 patients with primary pterygium into two groups similar in matter of age and sexe distribution. Group 1 underwent surgical suturing for conjunctival autografting and Group2 underwent sutureless autologous blood coagulum for that matter. We evaluated the primary outcome in terms of operative time, patients’ discomfort, graft displacement, graft failure and recurrences. The follow-up rate was at day1, week 1, month 1, 3 months and 6 months. Results: The operative time and patients’ discomfort were considerably reduced using the blood coagulum method (Operative time :15±3 minutes for Group 2 versus 32±2 minutes for Group1) (Patients discomfort p value <0.001). The graft failure and displacement were, however, higher in Group 2 compared to the first Group (p value for both is <0.001). The recurrence rate was equal in both groups. Conclusion: The use of autologous blood coagulum for conjunctival autografting is less time consuming and more comfortable for patients. However, the graft failure and displacement are more common with this technique.

Terson's syndrome is defined by an intraocular (vitreous, retinal or retrohyaloid) hemorrhage, consequent to an acute intracranial bleeding or a sudden elevated intracranial pressure. Undiagnosed early, Terson's syndrome can be responsible for serious ocular complication that can leads to complete vision loss. We report a 57 year old patient representing Terson's syndrome after an acute rupture of an aneurysm of the right sylvian artery. The rapid diagnosis and management of Terson's syndrome in our patient’s case allowed for a quick recovery and a better prognosis. Therefore, the importance of always thinking of Terson's syndrome a a possible diagnosis upon such clinical presentation.

Introduction: Primary open angle glaucoma (POAG) is a multi-factorial progressive optic neuropathy that results in gradual vision loss. Alongside an elevated intra ocular pressure (IOP), other factors influence the progression of retinal ganglion cells loss in POAG. Blood flow dysregulation and oxidative stress are believed to be important risk factors in the evolution of glaucomatous degenerative lesions. Magnesium is an essential cation for many reactions and enzyme activities in the human body. One of its crucial roles is vascular regulation and blood flow improvement by modifying endothelial function through endothelin (ET-1) and nitric oxide (NO) pathways. It is also considered as a neuro-protective molecule as it reduces the harmful effect of oxidative stress on retinal ganglion cells. Objective: the objective of this study is to assess the impact of daily intake of Magnesium on the stabilization of the glaucomatous damages on optic nerve. Methods: it is a nonrandomized monocentric clinical study. Patients having only POAG with an IOP values ≤ 19 mmHg and a visual acuity > to 5/10 were included. All patients had a daily supplementation of Magnesium for a period of at least 6 months each. All patients were assessed before the start of the study (T0), after 3 months of treatments (T1) and after 6 months of treatments (T2). At each visit, patients were given a full eye examination including IOP measures, perimetry, RNFL and GCC using OCT. Results: 46 patients with a mean age of 54 years old and a mean IOP of 16 mmHg were included. At T1 and T2 the values of mean deviation have regressed compared to T0. The mean IOP have significantly lessened and the RNFL and GCC values on OCT were stabilized. Conclusion: daily supplementation of Magnesium in patients with POAG has shown to be of great help on reducing the rate of progression of glaucomatous functional damage, therefore improving visual function and patients’ quality of life.
