Purpose: To report the efficacy of pegylated interferon alpha-2a (Roferon, Hoffmann-La Roche brands, Switzerland) in uveitic macular edema refractory to biologic agents.
Methods: Herein, we present two cases of non-infectious uveitis with cystoid macular edema (CME) who were unresponsive to immunosuppressant treatment, and whose uveitis and macular edema recurrences were prevented with subcutaneous injections of pegylated interferon α-2a.
Results: Two young males (27- and 30-year-old) diagnosed with non-infectious uveitis and CME were on immunosuppressive treatment. Although both received systemic steroids and biologic agents, macular edema persists. After initiation of pegylated interferon alpha-2a (Pegasys, Genentech, USA) CME regressed significantly and did not occur during their follow-ups of 14 and 12 months.
Conclusion: Pegylated interferon-alpha-2a can be used as an effective alternative to interferon alpha-2a in uveitic macular edema cases, resistant to other immunosuppressive agents.

This retrospective observational multicentre cohort study compared the rate of postoperative cystoid macular oedema (CME) between two intraocular lens (IOL) scleral fixation (SFIOL) techniques: a flanged IOL fixation technique (Yamane technique) and a suture IOL transscleral fixation technique (conventional technique). The study included 207 eyes with postoperative CME that had undergone SFIOL and were observed for > 12 weeks between January 2019 and January 2021. The primary endpoint was a comparison of the rate of postoperative CME at 3 months between groups.

Background: Idiopathic intracranial hypertension (IIH) is a condition where the pressure of the cerebrospinal fluid in the brain increases without a known cause. It typically affects adults but can also occur in adolescents and children, although it is less common. Numerous elements, including coagulopathy, have been documented in previous cases as potential etiological factors of IIH.

Purpose: To evaluate the outcomes of slow-coagulation transscleral cyclophotocoagulation (SC-TSCPC) in pseudoexfoliation glaucoma (PXG).
Methods: A single-center, retrospective non-comparative study including consecutive patients with medically uncontrolled PXG who underwent SC-TSCPC (1250-milliwatt power and 4-second duration). The primary outcome measure was surgical success (defined as intraocular pressure (IOP) between 6 - 21 mmHg with ≥20% reduction compared to baseline and no need for further glaucoma surgeries or development of vision-threatening complications).

Current treatments for retinal disorders are anti-angiogenic agents, laser photocoagulation, and photodynamic therapies. These conventional treatments focus on reducing abnormal blood vessel formation in the retina, which, in a low-oxygen environment, can lead to harmful proliferation of endothelial cells. This results in dysfunctional, leaky blood vessels that cause retinal edema, hemorrhage, and vision loss.
