Demographic pattern of refractive anomalies in Niger Delta presbyopes - Implications for preventive eye care practice

Abstract

Background/Aim: In spite of global initiatives to provide sight for all by the year 2020, many middle-aged to elderly people in the Niger Delta still have significant visual impairment due to uncorrected refractive errors. The aim of this study is to assess the types of refractive anomalies that occur among presbyopic patients in Port Harcourt and determine the demographic pattern of these anomalies based on age and gender characteristics.

Methodology: This is a hospital-based descriptive cross-sectional study in which sixty consecutive adult patients for refraction were seen. Every adult patient that came to get glasses during the study period was included in the study except where ocular or systemic contraindications were present. In addition to visual acuity, all patients had a detailed ocular examination and then refraction. The collected data was subsequently analysed using SPSS version 20.

Results: The mean age of the patients was 54.4 ± 9.4 years with a range of 35 to 80 years. A total of 60 patients were seen, comprising 30 males and 30 females. The commonest refractive error was presbyopia with hyperopic astigmatism and this accounted for 80% of all cases. Hyperopic presbyopia and presbyopia alone were the least common.

Conclusion: There is a high level of cylindrical and spherical errors in Port Harcourt. The full optical correction should always be prescribed to presbyopic patients to fully correct the associated visual impairment and improve the patients’ well-being.

Retinopathy of prematurity - Intersibling divergence of risk factors among twins

Introduction

Retinopathy of prematurity (ROP) is a consequence of an arrest in normal retinal neural and vascular development, which determines the aberrant retinal regeneration [1,2].

ROP is a disease process mostly reported in preterm neonates ranging from mild, transient changes in the retina with regression to severe progressive vasoproliferation, scarring, detachment of retina and blindness and it is common blinding disease in children and a major cause of vision loss among preterm infants [3]. Today it is well known that oxygen therapy is not the single causative factor, but many other risk factors play a causative role in the pathogenesis of ROP [4,5].

Two different patterns and outcome of neodymium YAG capsulotomy

Introduction

Visual impairment is a global health problem. Cataract is responsible for 50% of blindness worldwide [1].

Posterior capsular opacification is the most common late complication of cataract surgery as a result of proliferation of residual lens epithelial cells overall 25% of patients undergoing extra-capsular cataract surgery develops visually significant PCO within 5 years of the operation [2].

Using correlative microscopy for studying and treatment of Mycoplasma infections of the ophtalmic mucosa

Abstract

Purpose: We have studied in 18-month 21 patients showing kerato-conjunctivitis and/or dermato-blefaritis, where we will find a constant presence of mycoplasma in SEM optical cytology samples. The 21 patients were divided as follows: 7 allergic, 7 alleged allergic and 7 not-allergic, this division it makes between a clinical approach considering clinical history and symptoms. At the first examination, 16 of the 21 patients had a single or multiple infection in which the main pathogenic element was found to be Mycoplasma; the remaining 7, 4 of them were suspected allergic patients, 2 of it, were allergic subjects with the presence of eosinophils or mast cells.

Material and methods: All the study is constructed on citological optical microscopy and citological electron scanning microscopy (SEM) images for demonstrate the efficacy of the SEM in clinical approach at allergic, not allergic and suspected allergic patients.

Therapeutic treatment and Results: Treatment of the allergic and false allergic patients has made with local somministration of galenic composition with ialuronic acid 3 ml and Tetracycline hydrochloride 30 mg and with low level of cortisone and antisthaminic therapy. This treatment is necessary to eradicate the Mycoplasma infection and counteract toxic action of this pathogen on mucosa.

Discussion: After appropriate therapy we note that allergic patients have a greater predisposition to redundancy in infections in the short period (minimum 20 days), while alleged allergic patients have more prolonged infection periods (between 3 and 5 months), with constant presence at low levels of persistent Mycoplasma. The latter continue to show signs and symptoms similar to allergic patients, but with a negative test for tear IgE and absence of eosinophils and/or mast cells, in the optical and SEM samples displayed.
