Background: Stroke is a medical emergency of public health importance which affects the physical, mental, and emotional well-being of its victims. Management and rehabilitation are cumbersome for patients and caregivers. Ocular involvement and visual loss could further increase the burden of care.
Aim: To determine the prevalence of ocular disorders in patients with stroke in a Tertiary Hospital in Nigeria.
Materials And Methods: A descriptive hospital-based study was performed on all consenting and conscious adult patients aged 18 years and above with a diagnosis of stroke made within 1-year who were admitted to the stroke ward or attended the stroke clinic of the Neurology Unit in the Department of Medicine, University of Benin Teaching Hospital, Benin City from October 2013 to December 2013.
Results: A total of 170 eyes of 85 patients were studied with a mean age of 66.08 years ± 10.99; range 43-88 years. There was a male: female ratio of 2.6:1. Ocular abnormalities were documented in 95.5% of the patients. A presenting visual acuity of ≥6/18 was found in 66.7%. Mild ptosis and exotropia were seen in 2.9% and 0.6% of the eyes respectively. Intraocular pressure was between 10-21 mmHg in 87.7% eyes while 11.8% eyes had afferent pupillary defects. Cataract was seen in 71.8% eyes and optic nerve head changes in 48.8% eyes which includes temporal disc pallor and glaucomatous optic neuropathy in 29.4% and 14.2% eyes, respectively. Abnormalities found in the retina include retinal hemorrhages in 10.6% eyes, cotton wool spots in 2.4% eyes, and hard exudates in 7.8% eyes. Retinal vascular abnormalities were documented in 32.4% eyes. Visual complaints following stroke were documented in 9.6% of the patients.
Conclusion: Ocular abnormalities are present in patients with stroke, mostly due to predisposing risk factors for stroke, and age-related changes. Routine ophthalmic evaluation is suggested in the management of patients with cerebrovascular accident in our environment for better quality of care.

Aims: To compare the efficiency of scleral buckling (SB) and pars plana vitrectomy (PPV) with or without SB in patients with primary simple phakic fovea-splitting rhegmatogenous retinal detachment (RRD).
Methods: A retrospective case-control study included 101 patients aged <55 years diagnosed with phakic fovea-splitting RRD. The primary outcome was functional success, defined as achieving a postoperative logarithm of the minimum angle of resolution best-corrected visual acuity of 0.

Electrochemical biosensors can provide an economical, accurate and rapid method for early screening of disease biomarkers in clinical medicine due to their high sensitivity, selectivity, portability, low cost and easy manufacturing, and multiplexing capability. Tear, a fluid naturally secreted by the human body, is not only easily accessible but also contains a great deal of biological information. However, no bibliometric studies focus on applying electrochemical sensors in tear/eye diseases.

Purpose: Nitric oxide (NO) is recognized as an important biological mediator that controls several physiological functions, and evidence is now emerging that this molecule may play a significant role in the postnatal control of ocular growth and myopia development. We therefore sought to understand the role that nitric oxide plays in visually-guided ocular growth in order to gain insight into the underlying mechanisms of this process.
Methods: Choroids were incubated in organ culture in the presence of the NO donor, PAPA- NONOate (1.

Introduction: Recurrent uveitis (RU), an autoimmune disease, is a leading cause of ocular detriment in humans and horses. Equine and human RU share many similarities including spontaneous disease and aberrant cytokine signaling. Reduced levels of SOCS1, a critical regulator of cytokine signaling, is associated with several autoimmune diseases.
