Conjunctival impression cytology and tear film changes in patients with type 2 diabetes mellitus and its correlation with severity of diabetic retinopathy.

Purpose: Dry eye symptoms can substantially affect the quality of life and visual outcome. There are several studies on ocular surface changes reported in diabetic patients. There is limited literature defining the relationship between dry eye with diabetic retinopathy (DR).

Protein Drug Delivery Using a Novel Maxillofacial Technique Targeting the Visual Pathway in the Brain, the Optic Nerve, and the Retina.

Protein drugs are used for treating many diseases of the eye and the brain. The formidable blood neural barriers prevent the delivery of these drugs into the eye and the brain. Hence, there is a need for a protein drug delivery system to deliver large proteins across blood-neural barriers.

Acute bilateral retrobulbar optic neuritis - An atypical sequela of COVID-19.

Coronavirus disease 19 (COVID-19) and its ophthalmic manifestations have been variably portrayed. We report a case of a 56-year-old female presenting with sudden-onset vision loss associated with painful extraocular muscle movements in both eyes following COVID-19. Visual acuity was counting fingers close to face.

Maxillofacial trauma and ocular injuries: reports from a prospective study from Pondicherry, India.

Purpose: To report the spectrum and the factors affecting the visual outcome of ocular injuries associated with maxillofacial trauma.

Methodology: A prospective observational study was carried out from January 2019 to June  2020 on patients of maxillofacial trauma at a rural tertiary care centre, in Pondicherry, India. Detailed history was obtained.

Diurnal variation of central corneal thickness and intraocular pressure in eyes with pseudoexfoliation.

Purpose: Pseudoexfoliation syndrome (PXS) is an age related microfibrillopathy characterized by deposition of whitish flaky material over various ocular tissues. PXS eyes are known to have thinner corneas and thus can lead to an underestimation in intraocular pressure measurement. The purpose of this study was to find if there is any variation in central corneal thickness and intraocular pressure in PXS eyes and if there was any relationship between them.

A comparative clinical study on the generation of nitrosative stress in cataractous lenses of smokers and non-smoker tobacco patients.

Aim:: To quantify the levels of nitric oxide, inducible nitric oxide synthase, and 3-nitrotyrosine in cataractous lenses of smokers and smokers who chewed tobacco in comparison with non-smokers and non-smokers who chewed tobacco.

Study Design:: A total of 80 cataractous lenses from smokers, non-smokers, smokers with tobacco chewing habit, and non-smokers with tobacco chewing habit were collected from the patients who had enrolled in the Department of Ophthalmology, Mahatma Gandhi Medical College & Research Institute, Puducherry.

Methods:: Levels of nitric oxide, inducible nitric oxide synthase, and 3-nitrotyrosine were quantified using commercially available enzyme-linked immunosorbent assay kits.

Comparison of Central Corneal Thickness using Anterior Segment Optical Coherence Tomography Versus Ultrasound Pachymetry.

Introduction: Corneal thickness is an important and sensitive indicator of corneal health. It is useful in monitoring corneal diseases such as corneal oedema and keratoconus, and selecting patients for refractive surgery. Central Corneal Thickness (CCT) is a risk factor for Primary Open-Angle Glaucoma (POAG).

A rare case of branch retinal vein occlusion following Sirsasana.

Sirsasana is a type of headstand postural yoga in which the body is completely inverted. It is performed with or without wall support. In this position, the body is held upright supported by the forearms, while the crown of the head rests lightly on the floor.

Role of Optical Coherence Tomography in Assessing Anterior Chamber Angles.

Introduction: Gonioscopy is the gold standard in assessing anterior chamber angles. However, interobserver variations are common and there is a need for reliable objective method of assessment.

Aim: To compare the anterior chamber angle by gonioscopy and Spectral Domain Optical Coherence Tomography (SD-OCT) in individuals with shallow anterior chamber.

Foveal and Macular Thickness Evaluation by Spectral OCT SLO and Its Relation with Axial Length in Various Degree of Myopia.

Purpose: To evaluate the foveal and macular thickness in various degrees of myopia and its association with axial length in low, moderate and high degrees of myopia.

Design: A cross-sectional study was done in the Department of Ophthalmology, MGMCRI, Pondicherry, India.

Materials And Methods: One hundred and twenty five eyes eyes of 64 myopic subjects between the age group of 20-40 who fulfilled the inclusion criteria were selected and complete ophthalmic examination was done.

Spontaneous expulsive suprachoroidal hemorrhage caused by decompensated liver disease.

Expulsive suprachoroidal hemorrhage can be surgical or spontaneous. Spontaneous expulsive suprachoroidal hemorrhage (SESCH) is a rare entity. Most of the reported cases of SESCH were caused by a combination of corneal pathology and glaucoma.

Two cases of bilateral ischemic optic neuropathy following coronary artery bypass grafting.

Postoperative vision loss (POVL) after major non-ocular surgery is a very rare but devastating complication since it has the potential to cause bilateral, severe and permanent loss of vision. The common major procedures resulting in POVL are cardiac and spinal procedures. We are reporting two patients who presented with features of bilateral anterior ischaemic optic neuropathy after coronary artery bypass grafting.
