Discontinuation of Nucleos(t)ide Analogues in HBeAg Negative Chronic Hepatitis B Patients: Risks and Benefits.

Chronic hepatitis B (CHB) remains a major threat to global public health, affecting 296 million people worldwide. Although there is no curative treatment for CHB today, the virus can be effectively controlled with current antiviral treatment strategies. Since HBsAg loss can rarely (1%) be achieved with current nucleos(t)ide analogues (NA) options, lifelong treatment is usually required in HBeAg-negative patients.

New Treatment Options in Chronic Hepatitis B: How Close Are We to Cure?

Hepatitis B virus (HBV) infection is the leading cause of chronic liver disease worldwide. HBV-infected patients are at a lifetime risk of developing liver cirrhosis and hepatocellular carcinoma (HCC). Today, pegylated interferon (Peg-IFN) and nucleos(t)ide analogs (NAs) are used in the treatment of patients with chronic hepatitis B (CHB).

Excessive conjunctival and scleral retraction during trabeculectomy: an unusual intraoperative complication.

Trabeculectomy is the gold standard surgery for achieving target intraocular pressure (IOP) in glaucoma. Besides the efficiency of trabeculectomy, intraoperative or postoperative complications such as, suprachoroidal hemorrhage, vitreous loss, malignant glaucoma, flat anterior chamber, hypotony, choroidal detachment, endophthalmitis, are also quite important. We present the management of excessive conjunctival and scleral retraction during trabeculectomy: an unusual intraoperative complication.

Methods: This cross-sectional study was performed in a single university hospital. The study included all patients aged 18 years and older hospitalized with a PCR-confirmed COVID-19 between May 30, 2021, and August 30, 2021.

Objective evaluation of changes in lens clarity after repeated injections of ranibizumab in patients with neovascular age-related macular degeneration.

Purpose: To objectively evaluate changes in lens densitometry in eyes with neovascular age-related macular degeneration (n-AMD) treated with repeated intravitreal ranibizumab injections during a 12-month period and to compare the results with those in untreated healthy fellow eyes and healthy control eyes.

Methods: In this prospective study, the 36 treated eyes and the 37 untreated fellow eyes of 38 patients with n-AMD and the 32 control eyes of 32 healthy individuals were analyzed. Lens densitometry was evaluated using the Scheimpflug imaging.

Afibercept treatment for macular edema with and without serous retinal detachment due to branch retinal vein occlusion.

Purpose: To evaluate the effectiveness of intravitreal aflibercept treatment for macular edema with and without serous retinal detachment due to branch retinal vein occlusion.

Methods: Thirty-seven eyes with branch retinal vein occlusion treated with intravitreal aflibercept injection for macular edema were evaluated retrospectively. The patients were divided into two groups according to whether they showed serous retinal detachment on spectral domain optical coherence tomography.
