Comparing keratometry readings with manual separation of lids and wire speculum in children under general anesthesia.

Purpose: Keratometry (K) readings are crucial for intraocular lens power calculation in cataract surgery. In children who do not cooperate, the keratometry is done under general anesthesia with a handheld autokeratometer. However, there is little consensus regarding the method for the measurement of K readings.

A novel simplified method for managing inadvertent tube cut during aurolab aqueous drainage implant surgery for refractory glaucoma.

We report a novel simplified method for managing inadvertent tube cut in a patient undergoing the Aurolab aqueous drainage implant (AADI) surgery for refractory neovascular glaucoma. Tube cut occurred while applying the polyglactin ligature suture used to avoid early postoperative hypotony. The short end of the cut tube was removed and the long end reinserted into the base plate of AADI.

The subjectivity of objective evaluation of torsion on fundus photographs by practicing strabismologists.

Purpose: To assess the variability of assessing the ocular torsion on fundus photographs among strabismus surgeons.

Methods: This was a prospective, noninterventional, clinical trial involving 16 trained and experienced squint surgeons participated in the study. Two videos were prepared of a total of 10 fundus pictures with or without lines for disc foveal angle.

Spectacle prescription in children: Understanding practical approach of Indian ophthalmologists.

Purpose: The aim of this study is to survey the management approach, regarding spectacle prescription in children, among Indian ophthalmologists.

Methods: A web-based, anonymous questionnaire (multiple choice questions dealing with practical aspects of pediatric refraction), was sent to available database of Indian ophthalmologists. The survey responses (depicted in %) were compared using the amount of pediatric clientele in one's practice (Group A: <25%, Group B: 25% or more).

Asymmetry of Retinal Nerve Fiber Layer and Posterior Pole Asymmetry Analysis Parameters of Spectral Domain Optical Coherence Tomography in Children.

Purpose: To determine inter- and intraocular differences in the retinal nerve fiber (RNFL) and posterior pole asymmetry analysis (PPAA) macular thickness parameters in children using spectral domain optical coherence tomography.

Method: A prospective, cross-sectional study involving 126 subjects between the age group of 5-15 years received a standardized eye examination including spectral domain optical coherence tomography for retinal nerve fiber layer and macular thickness measurements. Asymmetry was calculated as the difference between the right and left eyes as well as the superior and inferior area of one randomly selected eye for each subject.

The applicability of correction factor for corneal thickness on non-contact tonometer measured intraocular pressure in LASIK treated eyes.

Purpose: To determine the applicability of central corneal thickness (CCT) based correction factor for non-contact tonometer (NCT) measured intraocular pressure (IOP) readings.

Method: A prospective, non-randomized study involved 346 eyes of 173 consecutive patients with age ⩾21 years undergoing laser-assisted in situ keratomileusis (LASIK) for myopia and/or myopic astigmatism. The CCT and IOP were measured before and after the LASIK procedure.

Diagnostic accuracy of posterior pole asymmetry analysis parameters of spectralis optical coherence tomography in detecting early unilateral glaucoma.

Purpose: To report the diagnostic ability of posterior pole asymmetry analysis (PPAA) parameters of spectralis optical coherence tomography (OCT) in detecting early unilateral glaucoma.

Methods: A prospective, cross-sectional study which included 80 eyes of 80 normal subjects and 76 eyes of 76 patients with unilateral early primary open-angle glaucoma by Hodapp-Anderson-Parrish classification. All subjects were of age more than 18 years, best-corrected visual acuity 20/40 or better, and a refractive error within ± 5 diopter (D) sphere and ± 3 D cylinder.

Applicability of ISNT and IST rules to the retinal nerve fibre layer using spectral domain optical coherence tomography in early glaucoma.

Background: To report the applicability of ISNT (inferior>superior>nasal>temporal) and IST (inferior>superior>temporal) rules on the retinal nerve fibre layer (RNFL) using spectral domain optical coherence tomography (SD-OCT) for detecting early glaucoma.

Methods: A prospective, cross-sectional study which included 80 eyes of 80 normal subjects and 76 eyes of 76 patients with early glaucoma by Hodapp-Anderson-Parrish classification. All subjects were of age more than 18 years, best corrected visual acuity 20/40 or better and a refractive error within ±5 dioptres (D) sphere and ±3 D cylinder.

Recurrence of aqueous misdirection following pars plana vitrectomy in pseudophakic eyes.

We present a retrospective interventional case series of four patients with pseudophakic eye who developed recurrent aqueous misdirection following pars plana vitrectomy (PPV) for malignant glaucoma (MG). The patients were treated with neodymium: YAG (Yttrium Aluminum Garnet) laser hyaloidotomy/membranotomy through the patent peripheral iridectomy. The main outcome measure was resolution of MG.

Applicability of the ISNT and IST rules on retinal nerve fiber layer measurement on spectral-domain optical coherence tomography in normal Indian children.

Background: To determine the applicability of the ISNT (inferior>superior>nasal>temporal) and IST (inferior>superior>temporal) rules on retinal nerve fiber layer (RNFL) measurement on spectral-domain optical coherence tomography (SD-OCT) in normal children.

Methods: A prospective, cross-sectional study including consecutive subjects between the ages of 5-18 years who were born at term (≥37 weeks gestational age) and with a normal birth weight (≥2500 g) presenting to the out-patient department for refractive error examination. RNFL measurement was done on Spectralis SD-OCT.

A technique for standardizing disk foveal angle measurement.

Ocular torsion can been measured by perimetry, double Maddox rod, Bagolini glasses, indirect ophthalmoscopy lens, slit-lamp biomicroscopy, synoptophore, and fundus photography. Wide variations have been reported in the measurement of the disk foveal angle (DFA) using fundus photography. We describe a technique for measuring the DFA, formed by a horizontal line extending from the center of the optic disk and a line from the center of disk to the fovea, using Microsoft PowerPoint and ImageJ software.

Outcomes of Ahmed valve implant following a failed initial trabeculotomy and trabeculectomy in refractory primary congenital glaucoma.

Purpose: The aim was to report the outcome of Ahmed glaucoma valve (AGV) (New World Medical, Inc., Rancho Cucamonga, CA, USA) implantation as a surgical intervention following an initial failed combined trabeculotomy + trabeculectomy (trab + trab) in refractory primary congenital glaucoma (RPCG).
