Significance: This study explores the difference between cycloplegic and noncycloplegic refraction in young adult myopes.

Purpose: From the available literature, it is unclear whether cycloplegia is necessary when refracting young adults. This study investigates the agreement between noncycloplegic autorefraction and cycloplegic autorefraction and investigates factors affecting the agreement between the two methods.

To evaluate the effect of mean ocular perfusion pressure on the foveal avascular zone (FAZ) area in eyes with successful retinal detachment (RD) surgery. This prospective pilot fellow eye-controlled study measured the intraoperative mean ocular perfusion pressure in eyes having surgery for rhegmatogenous RD (RRD). Postoperatively, the FAZ area was measured; the change was calculated as the difference in the FAZ area between the operated eye and the contralateral control eye.

Suprachoroidal silicone oil migration is an unusual complication of small gauge 3 ports Pars plana vitrectomy (3PPV) system. Our objective is to report a retrospective, observational case of an intra-operative suprachoroidal silicone oil (SO) migration during 27 gauge 3PPV and its successful surgical management. A 49 years old male patient with type 2 diabetes, presented to the ophthalmology outpatient department with reduced visual acuity in his right eye.

Article Synopsis
  • * Data collected over 3 months revealed that most patients experienced complete resolution of symptoms, with an average recovery time of 42 days; older patients and those with longer hospital stays showed slower recovery rates.
  • * The severity of COVID-19 or patient gender did not significantly affect the recovery process, suggesting eyelid myokymia could be a temporary note during recovery from the illness.

von Hippel-Lindau (VHL) syndrome is a multisystem neoplastic disorder involving eyes, central nervous system, kidneys, spine, and other tissues. A retinal capillary hemangioma (RCH) is the earliest manifestation of the VHL disease in most cases.This paper aims to provide an up-to-date review of the current literature about von Hippel-Lindau syndrome.

Objective: To assess the reliability and validity of gray level co-occurrence matrices (GLCM) in the quantification of choriocapillaris and describe GLCM features in normal and eyes with resolved acute posterior multifocal placoid pigment epitheliopathy (APMPPE) and serpiginous choroiditis (SC).

Methods: In this, multicenter, reliability, validity and comparative study; OCTA was performed on eyes with resolved APMPPE and SC and normal individuals. CC texture classification, low flow area measurements and GLCM feature extraction were performed.

Background And Objective: To evaluate the flow characteristics and textural properties of choriocapillaris (CC) on optical coherence tomography angiography in eyes with resolved inflammatory choriocapillaropathies and Vogt-Koyanagi-Harada (VKH) disease.

Patients And Methods: A cohort of eyes with healed acute posterior multifocal placoid pigment epitheliopathy (APMPPE), serpiginous choroiditis (SC), and VKH disease were included. A 3 mm × 3 mm OCT angiogram of CC was acquired and graded for flow characteristics and textural properties.

Background: Frequently, hospitalized patients are referred for transthoracic echocardiograms. The availability of a pocket mobile echocardiography device that can be incorporated on bedside rounds by cardiologists may be a useful and frugal alternative.

Methods: This was a cross-sectional study designed to compare the accuracy of pocket mobile echocardiography images with those acquired by transthoracic echocardiography in a sample of hospitalized patients.
