Purpose: The choroidal thickening and serous retinal detachments that characterize Vogt-Koyanagi-Harada (VKH) disease can be imaged in detail using spectral domain optical coherence tomography (SD-OCT). Whether specific qualitative and quantitative SD-OCT features at presentation were associated with visual outcomes in a randomized controlled trial comparing methotrexate to mycophenolate for steroid-sparing control of uveitis were evaluated.

Methods: An exploratory subanalysis of data from the FAST trial in which SD-OCT images from VKH participants were analyzed for presence/absence of bacillary detachments, retinal pigment epithelium (RPE) folds, and internal limiting membrane (ILM) fluctuations was performed.

Purpose: To compare the effectiveness of methotrexate (MTX) and mycophenolate mofetil (MMF) in achieving corticosteroid-sparing control of uveitis in patients with Vogt-Koyanagi-Harada (VKH) disease.

Methods: A subanalysis of patients with VKH from the First-line Antimetabolites as Steroid-sparing Treatment Uveitis Trial, a randomized, observer-masked, comparative effectiveness trial, with comparisons by treatment (MTX vs MMF) and disease stage (acute vs chronic). Individuals with noninfectious uveitis were placed on a standardized corticosteroid taper and block randomized 1:1 to either 25 mg weekly oral MTX or 1.

Background: The purpose of this study was to present a modified surgical technique involving pars plana vitrectomy with large chorioretinectomy for eyes with rupture of the globe due to severe ocular blunt trauma.

Methods: This retrospective study included consecutive patients with rupture of the globe due to blunt trauma who were treated at the King Khaled Eye Specialist Hospital (Riyadh, Saudi Arabia). All patients underwent 25-gauge pars plana vitrectomy with large chorioretinectomies involving all the tissue around the posterior scleral wounds.

Background: The antimetabolites methotrexate (MTX) and mycophenolate mofetil (MMF) are commonly used as initial corticosteroid-sparing treatment for uveitis. There is little data examining risk factors for failing both MTX and MMF. The objective of this study is to determine risk factors for failing both MTX and MMF in patients with non-infectious uveitis.

Purpose: To evaluate how changes in visual acuity are associated with changes in quality of life (QoL) among patients with non-infectious uveitis taking antimetabolites.

Methods: This secondary analysis of the multicenter First-line Antimetabolites as Steroid-sparing Treatment (FAST) Uveitis Trial involves 216 participants randomized to methotrexate or mycophenolate mofetil. Vision-related (NEI-VFQ and IND-VFQ) and health-related (PCS and MCS SF-36v2) QoL and visual acuity were measured at baseline and 6-month primary endpoint.

Article Synopsis
  • Vogt-Koyanagi-Harada (VKH) disease is an autoimmune condition that impacts tissues like the eyes and skin, and this report highlights a rare case of photoreceptor layer regeneration in a child after total loss.
  • A 12-year-old boy with VKH experienced severe blood sugar spikes and pituitary gland changes after receiving steroid treatment but had no prior health issues.
  • Following treatment and management of his hyperglycemia, imaging showed noticeable regeneration of the photoreceptor layer, suggesting possible recovery after inflammation subsides.

Retinal periphlebitis is a subtype of retinal vasculitis affecting the retinal veins. We report a case of bilateral branch retinal vein occlusion (BRVO) associated with idiopathic retinal periphlebitis and complicated by subfoveal hemorrhage (SFH). An 18-year-old woman presented with best-corrected visual acuity of 20/20 in the right eye and 20/30 in the left eye.

Background: Central serous chorioretinopathy (CSCR) is an idiopathic condition characterized by serous retinal detachment and/or retinal pigment epithelial (RPE) detachment, the condition associated with a fluid leak through the RPE into subretinal space. This article reports on an unusual case of CSCR following taking adulterated honey mixed with tadalafil powder.

Case Presentation: A 38-year-old male, not known to have any medical illnesses, came to our ophthalmology clinic complaining of sudden onset of blurred central vision in the left eye for five days after taking an adulterated honey which was claimed to improve sexual performance.
