Smartphone-aided Quantification of Iridocorneal Angle
This article presents the possibility of iridocorneal angle (ICA) estimation through smartphone-captured images. Such measured inferior ICA (at 6’o clock position) was comparable to the anterior segment optical coherence tomography measured trabecular iris angle at 500 μ at 270 degrees (P=0.06). They both had an excellent positive correlation (ρ=0.81, P (Source: Journal of Glaucoma)

Smartphone-based Gonio-Imaging: A Novel Addition to Glaucoma Screening Tools
Gonioscopy is one of the most difficult skill acquired by ophthalmologists. It is one of the key components of glaucoma diagnosis and management. Smartphone based imaging solutions have revolutionised the imaging in ophthalmology by virtue of their ease of use and portability. Authors hereby describe a smartphone based gonioimaging technique with a 4-mirror goniolens, which can detect the gross findings in anterior chamber angle, and thus can be utilised as screening tool for glaucoma.

Episcleral Venous Pressure and the Ocular Hypotensive Effects of Topical and Intracameral Prostaglandin Analogs
There is a limit beyond which increasing either the concentration of a prostaglandin analog (PGA) or its dosing frequency fails to produce increases in ocular hypotensive efficacy with topical dosing. Intracameral PGA dosing with a bimatoprost implant, however, does not exhibit the same intraocular pressure (IOP)-lowering plateau at studied concentrations, and the maximum-achievable ocular hypotensive effects are not yet known. This suggests that the bimatoprost intracameral implant may activate another mechanism of action in addition to the mechanism(s) activated by topical application. Episcleral venous pressure (EVP) is...

Progressive High Hypermetropic Shift as a Refractive Surprise Following Glaucoma Filtration Surgery in a Phakic Child With Early-Onset Childhood Glaucoma Associated With Axenfeld-Rieger Anomaly
Conclusions: Present case is the first to describe the unusual presentation of progressive high hypermetropia in a child with Axenfeld- Rieger anomaly with congenital glaucoma after surgical intervention for glaucoma. Childhood glaucoma is classically associated with myopic shift in refraction and refraction is one of the most important clinical parameter measured at every follow-up visit. Although progressive hypermetropic shift is a rare occurrence, clinicians should be aware of this possibility. Keratomerty should be performed when such refractive surprises arise, which may help detect the clinical condition and the e...

Gravitational Influence on Intraocular Pressure: Implications for Spaceflight and Disease
Spaceflight-associated neuro-ocular syndrome (SANS) describes a series of morphologic and functional ocular changes in astronauts first reported by Mader and colleagues in 2011. SANS is currently clinically defined by the development of optic disc edema during prolonged exposure to the weightless (microgravity) environment, which currently occurs on International Space Station (ISS). However, as improvements in our understanding of the ocular changes emerge, the definition of SANS is expected to evolve. Other ocular SANS signs that arise during and after ISS missions include hyperopic shifts, globe flattening, choroidal/re...
