Evaluation of stress distribution in and around dental implants using three different implant-abutment interfaces with platform-switched and non-platform-switched abutments: A three-dimensional finite element analysis.

Background: A key factor for the success or failure of an implant is how the stresses are transferred to the surrounding bone. The implant‒abutment connection (IAC) is paramount for implant success. The purpose of this finite element analysis (FEA) study was to evaluate the stress distribution in and around three different implant‒abutment interfaces with platform-switched and platform-matched abutments using the finite element method (FEM).

ROP examination of premature babies at an eye hospital referred from urban and semi-urban NICUs.

Introduction: Retinopathy of prematurity (ROP) is seen in low gestational age (GA) and birth weight (BW) babies leading to retinal vascular damage. Screening of preterm would help in early identification of this, sight-threatening disease. Multiple factors play an important role in planning screening strategies for these preterm.

Post-traumatic endophthalmitis in children.

Purpose: To study the clinico-microbiological profile and evaluate the functional and anatomical outcomes of pediatric post-traumatic endophthalmitis (PPTE).

Methods: This was a retrospective interventional case series. All medical case records of patients diagnosed with PPTE over a 5-year period from January 2011 to December2015 were reviewed.

Optic nerve head retinal artery macroaneurysm: Report of a case.

A 61-year-old elderly male, hypertensive patient presented to the retina clinic with sudden drop in vision in the left eye for 6 days. His best-corrected visual acuity at presentation was counting fingers close to face. Fundus examination of the left eye revealed the presence of subretinal and preretinal haemorrhage at the macula along with hypertensive retinopathy changes in both eyes.

Capillary Dropout: A Novel Fluorescein Angiography Finding in Primary Vitreoretinal Lymphoma.

Tissue diagnosis with vitreous and/or retinal biopsy usually confirms the diagnosis of primary vitreoretinal lymphoma. Multiple imaging modalities like fundus fluorescein angiography, fundus autofluorescence, and optical coherence tomography have been used to support the diagnosis of vitreoretinal lymphoma. We report a case of a 74-year-old lady diagnosed with primary vitreoretinal lymphoma showing a novel fluorescein angiographic finding of capillary dropout.

Retinal meteor.

We describe a case of a 65-year old man diagnosed with retinal vasoproliferative tumour secondary to posterior uveitis. The fluorescein angiography shows an interesting meteor-like leak emanating from the tumour and rising towards the superior retina in the later frames of the angiogram. Pictorially, we call it the "Retinal Meteor" and also describe the possible mechanism for this pattern of leakage.

ARTEFACTUALLY DAMPENED FLASH STIMULUS VISUAL EVOKED RESPONSES IN A SILICONE OIL-FILLED EYE.

Purpose: To report a case of falsely dampened visual evoked responses in a patient of Usher syndrome after retinal detachment surgery secondary to probable intraocular silicone oil.

Methods: Retrospective observational case report.

Case Description: A 16-year-old boy with Usher syndrome developed rhegmatogenous retinal detachment in the left eye.

Appraising the spectrum of firework trauma and the related laws during Diwali in North India.

Purpose: To evaluate the epidemiological characteristics and outcomes of ocular injuries resulting from the use of firecrackers during the Diwali festival in all age groups.

Materials And Methods: A single-center, retrospective, hospital-based case series presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in North India during the 5 days of Diwali festival from 2011 to 2015 was conducted.

Results: A total of 53 eyes of 45 patients were included in the study, out of which the vast majority (39/87%) were males.

Ocular infection with Gliocladium species-report of a case.

Purpose: The purpose of this study is to report a case of ocular infection with Gliocladium species due to an exposed scleral buckle.

Design: Interventional case report was used as the study design.

Methods: A 60-year-old diabetic male patient presented with persistent pain, redness, and discharge in his left eye since 2 months.

Clomiphene citrate-induced visual hallucinations: a case report.

Background: Polycystic ovary syndrome is a common cause of chronic anovulation and infertility in otherwise healthy fertile couples. Clomiphene citrate is used as a first-line ovulation induction therapy in patients with polycystic ovary syndrome. Clomiphene citrate can cause both systemic and ocular side effects.

IATROGENIC CHOROIDAL NEOVASCULAR MEMBRANE IN MACULAR HOLE-INDUCED RETINAL DETACHMENT.

Purpose: To report a case of choroidal neovascular membrane after vitreoretinal surgery in a patient with macular hole-induced retinal detachment.

Methods: Retrospective observational case report.

Case Description: A 64-year-old lady presented with sudden drop in vision in the right eye since 20 days.
