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.

Cataract surgery is ranked among the most frequent operations, affecting a population over 65 years of age.Its prognosis is often favorable, however, there are rare complications including inflammation of the anterior segment known as Anterior Segment Toxicity Syndrome . the majority of our patients were men and diabetes appear in almost half and all our patients present various symptoms the first 24 hours dominated by the attack of the anterior segment our therapeutic attitude consists in the use of corticosteroids and hypotonizers with a good evolution in the majority of patients.

Sildenafil citrate is phosphodiesterase 5 inhibitor (PDE5i) that is widely used to treat male erectile dysfunction. However, this molecule has been associated with many visual side effects which most are transient but some can lead to persistent vision loss. Non arteritic anterior ischemic neuropathy (NAION) has been reported in some cases as a very rare, but possible, Sildenafil citrate’s visual adverse effect. We present the case of young patient under erectile dysfunction medication who developed an induced toxic neuropathy, while reviewing the other reported cases in medical literature.

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.
