Macular Microvasculature in High Myopia without Pathologic Changes: An Optical Coherence Tomography Angiography Study.
To investigate macular microvasculature changes using optical coherence tomography angiography (OCTA) and analyze their correlation with the structural parameters in highly myopic eyes. ⋯ The FAZ was enlarged and the parafoveal vascular density was reduced in the highly myopic eyes. The decrease was prominent in the superficial capillary plexuses and well-correlated with the retinal thickness profiles. The macular microvascular network alteration may be attributed to the ocular axial elongation that occurs with myopia.

Effect of Preoperative Factor on Intraocular Pressure after Phacoemulsification in Primary Open-angle Glaucoma and Primary Angle-closure Glaucoma.
To compare the effects of cataract surgery on intraocular pressure (IOP) according to preoperative factor in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). ⋯ For patients with relatively low peak IOP who used fewer medications before surgery, cataract surgery alone was effective for IOP control in both POAG and PACG patients. Conversely, For POAG patients with a history of higher peak IOP and who used more medications, cataract surgery was not effective in lowering IOP, whereas it resulted in relatively good IOP values in PACG patients.

To determine the frequency of ocular diseases in infants visiting the ophthalmology department of a tertiary care hospital. ⋯ Acquired ocular diseases were more common than congenital ocular diseases. The most common ocular pathology was conjunctivitis, followed by congenital nasolacrimal duct obstruction, in infants. Conjunctivitis was more common in neonates than infants.

Effectiveness of Intravitreal Ranibizumab for Diabetic Macular Edema with Serous Retinal Detachment.
To evaluate the effectiveness of intravitreal injection of ranibizumab (IVR) in treating diabetic macular edema (DME) with serous retinal detachment (SRD) based on spectral domain optical coherence tomography (SD-OCT) patterns. ⋯ A significant reduction in CFT with required IVR injections in DME with SRD was achieved but was accompanied by a worse functional outcome in the SRD group. The presence of subretinal fluid on SD-OCT in study eyes may be a poor prognostic factor for visual acuity.

Comparative StudyComparative Efficacy of the New Optical Biometer on Intraocular Lens Power Calculation (AL-Scan versus IOLMaster).
To evaluate the agreement in axial length (AL), keratometry, and anterior chamber depth measurements between AL-Scan and IOLMaster biometers and to compare the efficacy of the AL-Scan on intraocular lens (IOL) power calculations and refractive outcomes with those obtained by the IOLMaster. ⋯ Measurement by AL-Scan provides reliable biometry data and power calculations compared to the IOLMaster; however, refractive outcomes of Tecnis-inserted eyes by AL-Scan calculated using SRK/T can show a slight myopic tendency.
