Screening of haitian children between the ages of 3 and 6 years old for amblyogenic risk factors with the use of the Spot photoscreener. The photoscreener results will be compared to the complete ophthalmologic evaluation. Primarily, this will allow evaluation of the performance of the spot photoscreener in the haitian children population. Secondarily, this study will gather epidemiological information on vision problems in the haitian children population.
Screening of haitian children between the ages of 3 and 6 years old for amblyogenic risk factors with the use of the Spot photoscreener before and after cycloplegia. The photoscreener results will be compared to the complete ophthalmologic evaluation. The ophthalmologic evaluation includes visual acuity, ocular alignment, slit lamp evaluation, cycloplegic refraction and dilated fundus evaluation. First of all, this will allow evaluation of the performance of the spot photoscreener in the haitian children population. Second of all, this study will gather epidemiological information on vision problems in the haitian children population.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Spot photoscreener | Automated vision screener: Spot Vision Screener VS 100, Welch-Allyn. This photoscreener is a portable device, using an infrared light. It is built to detect amblyogenic risk factors. First of all, the spot photoscreener produces a sounds which attracts the child's attention and helps him shift his gaze towards the device, held at 1 meter in front him. The spot then evaluates for refractive errors, anisocoria, strabismus, ptosis and media opacity. The ophthalmologic evaluation consists of the measure of the visual acuity, ocular alignment, anterior and posterior segment. The patient will be cyclopleged with cycloplegic drops and will be refracted to obtain a cyclopleged refraction. This will determine his refractive error. |

|---|---|---|
| Number of patients presenting significant ophthalmologic pathologies in an haitian pediatric population | The epidemiology of vision problems will be evaluated in a sample of haitian children. The ophthalmologic exam will be considered abnormal if it denotes a significant ophthalmologic pathology. A significant ophthalmologic pathology is defined as a significant refractive error, a significant strabismus or a significant media opacity according to the 2013 American Association for Pediatric Ophthalmology and Strabismus (AAPOS) Guidelines for automated preschool vision screening. An ophthalmologic pathology is also considered significant in cases of severe ophthalmologic pathologies (xerophthalmia, trachoma, cataract >1mm, glaucoma, retinopathy of prematurity, retinoblastoma). | 7 days |
| Measure | Description | Time Frame |
|---|---|---|
| Performance of the Spot photoscreeners in comparison with the ophthalmologic exam to denote significant ophthalmologic pathologies according to the 2013 AAPOS guidelines in an haitian pediatric population | Sensitivity, specificity, positive predictive value and negative predictive value of the abnormal automated vision screening with the photoscreener in comparison of the abnormal screening of the ophthalmologic exam using the criteria of the AAPOS guidelines (gold standard). A significant ophthalmologic pathology is defined as a significant refractive error, a significant strabismus or a significant media opacity according to the 2013 American Association for Pediatric Ophthalmology and Strabismus (AAPOS). The results of the test, being normal vs abnormal, will be compared. |
