Concentric Macular Rings Without Ocular Pathology

Introduction: Refractive error is a common cause of amblyopia. Objective: To determine prevalence of amblyopia and the pattern and the types of refractive error in children with amblyopia in a tertiary eye hospital of Nepal. Materials and methods: A retrospective chart review of children diagnosed with amblyopia in the Nepal Eye Hospital (NEH) from July 2006 to June 2011 was conducted. Children of age 13+ or who had any ocular pathology were excluded. Cycloplegic refraction and an ophthalmological examination was performed for all children. The pattern of refractive error and the association between types of refractive error and types of amblyopia were determined. Results: Amblyopia was found in 0.7 % (440) of 62,633 children examined in NEH during this period. All the amblyopic eyes of the subjects had refractive error. Fifty-six percent (248) of the patients were male and the mean age was 7.74 ± 2.97 years. Anisometropia was the most common cause of amblyopia (p < 0.001). One third (29 %) of the subjects had bilateral amblyopia due to high ametropia. Forty percent of eyes had severe amblyopia with visual acuity of 20/120 or worse. About twothirds (59.2 %) of the eyes had astigmatism. Conclusion: The prevalence of amblyopia in the Nepal Eye Hospital is 0.7%. Anisometropia is the most common cause of amblyopia. Astigmatism is the most common types of refractive error in amblyopic eyes. Nepal J Ophthalmol 2013; 5(9):38-44 DOI: http://dx.doi.org/10.3126/nepjoph.v5i1.7820

In today’s world computers are ubiquitous and found in different forms which can effect intraocular pressure (IOP). Present study was undertaken to find out effect of day-to-day exposure to computer screen on IOP in normal individuals. 70 individuals (who met the screening conditions and devoid of obvious ocular pathology and systemic diseases) had their IOP’s checked before and 4 hour after computer session on same day, all working in general day shift, involving reading English printed material. The results showed significant (p<0.005) increase with IOP values before exposure being 17.89±3.25 and 16.99±2.84 and after exposure being 19.67±3.4 and 18.70±2.4 in left and right eye respectively. Increase in IOP was noted in 70% and 67% individuals in left and right eye. Differences in IOP of right and left eye may be due to dominance of eye or direction of script from left to right.
