Comparison of spectral domain optical coherence tomography parameters between disc suspects and "pre-perimetric" glaucomatous discs classified on disc photo.

Purpose: The aim of this study was to compare SD-OCT parameters between disc suspects and "pre-perimetric" glaucomatous discs classified on disc photos.

Methods: Disc photos of suspicious discs with normal Humphrey visual fields (HVF) were graded as normal or pre-perimetric glaucomatous based on the consensus of three masked glaucoma specialists. RNFL and GCL-IPL maps of SD-OCT (Cirrus OCT) of these eyes were studied.

Secondary ocular hypertension post intravitreal dexamethasone implant (OZURDEX) managed by pars plana implant removal along with trabeculectomy in a young patient.

We report a case of refractory secondary ocular hypertension after insertion of dexamethasone implant (OZURDEX) for posterior uveitis in a young patient, which necessitated removal of the implant through pars plana vitrectomy along with a trabeculectomy. A young male developed secondary ocular hypertension following dexamethasone implant (OZURDEX) injection for control of posterior uveitis. As the implant was still present in the vitreous cavity, we successfully performed a pars plana removal of the implant along with trabeculectomy with mitomycin C.

A case of idiopathic necrotizing scleritis with secondary glaucoma treated successfully with golimumab and Ahmed valve implantation.

A 52-year-old woman presented with idiopathic active scleritis not responding to oral cyclophosphamide, azathioprine, and oral steroid. Her intraocular pressure in the left eye was 45 mm of Hg in spite of using combination of brinzolamide 1% and brimonidine 0.2% (thrice a day), timolol maleate 0.

Can Corneal Biomechanical Properties Explain Difference in Tonometric Measurement in Normal Eyes?

Significance: Corneal biomechanical parameters can affect intraocular pressure (IOP) measurements by different tonometers compared with Goldmann applanation tonometer. This study implies that corneal hysteresis (CH) and corneal resistance factor (CRF) better explain variability in IOP measurements.

Purpose: The aim of this study was to evaluate the effect of corneal properties on the difference in IOP measured by the Ocular Response Analyzer (ORA), Rebound Tonometer (RBT), Dynamic Contour Tonometer (DCT), and Tono-Pen from the Goldmann applanation tonometer (GAT).
