“…This may be because one-third of the subjects had bilateral amblyopia due to high ametropia and visual acuity was better in eyes with bilateral amblyopia than the eyes with unilateral amblyopia (Lesueur et al, 1998). Visual acuity of 20/80 was found in the highest number of amblyopic eyes.…”

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.

“…7,8 The presence of systemic disorders have been associated with poor visual acuity in bilateral cases, reflecting additional causes of poor vision. 4 Many previous studies have included both unilateral and bilateral cataracts within the same study. However, there have been limited studies based solely on bilateral cataracts in children, 9 and to our knowledge, a model to predict visual acuity before surgery has yet to be developed.…”

Purpose The objective of this study was to investigate preoperative factors associated with postoperative visual acuity outcomes and to develop a model to predict visual acuity prognosis. Methods A retrospective study was conducted by reviewing clinical charts of pediatric patients who underwent bilateral cataract surgery by a single surgeon (MEW) at the Storm Eye Institute. A multiple logistic regression model was constructed to predict the odds of poor postoperative visual acuity, that is, worse than 20/40, based on age at surgery, gender, primary intraocular lens (IOL) placement, ethnicity, and preoperative nystagmus. Results A sample size of 157 children (314 eyes) was investigated with median duration of follow-up of 6.4 years. A total of 78% of children with bilateral cataract had postoperative visual acuity of 20/40 or better. The presence of preoperative nystagmus was highly correlated with poor postoperative visual acuity (OR = 6.0; 95% CLs, 2.5-14.1; P-valueo0.0001). Children of age o1 year at time of cataract extraction (OR = 3.2; 95% CLs, 1.4-7.6; P-value = 0.0073), male gender (OR = 2.3; 95% CLs, 1.1-4.5; P-value = 0.02), the absence of primary IOL placement (OR = 3.0; 95% CLs, 1.05-8.4; P-value = 0.04), and non-Caucasian ethnicity (OR = 2.0; 95% CLs, 1.02-4.03; P-value 0.0447) were associated with poor visual acuity postoperatively. Conclusions Satisfactory visual outcomes occurred in 78% of children operated on for bilateral cataracts. Preoperative nystagmus, age o1 year at time of cataract extraction, absence of primary IOL placement, male gender, and non-Caucasian ethnicity, were all factors associated with poor postoperative visual acuity.

“…Currently, congenital cataract represents a challenge to the ophthal mologist who should perform the ocular globe anatomic restoration before two months of age so to prevent the amblyopia in the unilateral cataract. Treating a child is more complex than treating an adult, considering the greater inflammatory response on an infant, surgery time, and the needed aphakia rehabilitation to obtain a good result in the long run (18)(19)(20) . The main purpose of this study is to provide data about the diagnostic and surgical treatment of patients who had their unilateral …”

Registered with the fundación visión's ethics committee under number: 002/2013. AbsTRACTPurpose: Providing data on the late diagnosis and surgical treatment of patients who underwent surgery for total unilateral congenital cataract. Methods: Systematic retrospective review of the medical record of all patients between 0 and 16 years old with total unilateral congenital cataract who underwent surgery at Fundación Vision between January 2010 and July 2012. Results: Medical records of 37 patients (51 % females) were studied, age was 7.4 (± 4.9) years (average ± SD) and 62% lived on Departamento Central (the most populated region from Paraguay). A total of 97.3% patients underwent late surgical treatment and 86.5% received a late diagnosis. The average time elapsed between the diagnosis and the surgical treatment was one month, and 62.2% of the patients underwent surgery within six months from the diagnosis. Conclusion: This study evidences that most of the patients in our series had a late treatment as a result of a late diagnosis. Based on these results we recommend establishing strategies to improve the early detection and surgical treatment of the newborns.
