Purpose:The aim of this study is to identify common causes, associated ophthalmological abnormalities, and systemic comorbidities in children in Andhra Pradesh, India, with cerebral visual impairment (CVI).Methods:A retrospective review of case records of all children aged <16 years with diagnosis of CVI seen between January 2016 and December 2016 was carried out. Data were collected for their age, gender, cause of CVI, refraction, accommodation, anterior and posterior segment examination findings, and systemic problems.Results:A total of 124 patients were identified and studied (80 boys and 44 girls, mean age 5.23 years, 44.8% aged <2 years). The most common causes of CVI were hypoxic–ischemic encephalopathy (HIE) (34.4%), undetermined etiology (32.8%), neonatal seizures, and infantile spasms (16% each). The most common presenting complaints were poor vision (76%) and squint (11.2%). Profound visual impairment was seen in 88.8%, and 11.2% had high functioning CVI. Fifty-eight (46.4%) patients had significant refractive errors, 40 (32.25%) had strabismus, 4 (3.2%) had visually significant cataract, and 40 (32%) had optic atrophy. Motor delay was observed in 39.5%, speech delay was evident in 22.4%, and cognitive delay in 16%.Conclusion:HIE is the most common cause (one-third) of CVI in our population, and the majority of them presented at age <2 years (44.8%) with profound visual impairment (88.8%). A significant number of them have treatable ophthalmic conditions such as refractive errors (46.4%), accommodative insufficiency (12.1%), and cataract (3.2%), and more than one-third of them also have delay in other areas of development.

Purpose To determine the long-term surgical and visual outcomes in Indian children with early-onset glaucoma associated with Axenfeld-Rieger anomaly (ARA). Methods This is a retrospective analysis of 44 eyes of 24 consecutive children with early-onset glaucoma (within 3 years of age) and ARA who underwent glaucoma surgery over a 20-year period (1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010) by a single surgeon. Main outcome measures were pre-and postoperative intraocular pressures (IOPs), corneal clarity, visual acuities (VAs), refractive errors, success rate, time of surgical failure, and complications. Results The series consisted of 38 primary combined trabeculotomy-trabeculectomy (CTT) and 6 primary trabeculectomy procedures (Schlemm's canal could not be identified in these eyes). There was a statistically significant reduction in IOP postoperatively (27.07 ± 4.88 vs 14.88 ± 3.62 mm Hg; Po0.0001) with a mean reduction of 45.14%. Success probability by Kaplan-Meier survival analysis was 93% till 5 years, and then 88. 1%, 82.3%, 70.5%, 56.4%, and 42.3% at year 6, 7, 8, 9, and 10, respectively. Preoperative corneal edema was present in 43/44 eyes (97.72%) and cleared in 42 eyes (97.67%). There was one case each with intraoperative hyphema and with shallow chamber postoperatively and both were successfully managed successfully. There was no incidence of endophthalmitis or any other sight-threatening complication. Data on VA were available in 34 eyes (77.3%). At final follow-up visit, 15 (44.1%) eyes had best corrected VA ⩾ 6/18. Conclusions Primary CTT is safe and effective for early-onset glaucoma associated with ARA. It leads to excellent IOP control and satisfactory visual outcome.

Purpose:The purpose was to study choroidal thickness and its profile based on location in healthy Indian children using enhanced depth spectral-domain-optical coherence tomography (SD-OCT).Methods:In this cross-sectional observational study 255 eyes of 136 children with no retinal or choroidal disease were consecutively scanned using enhanced depth SD-OCT. Eyes with any ocular disease or axial length (AXL) >25 mm or < 20 mm were excluded. A single observer measured choroidal thickness from the posterior edge of the retinal pigment epithelium to the choroid/sclera junction at 500-microns intervals up to 2500 microns temporal and nasal to the fovea. Generalized estimating equations were used to evaluate the correlation between choroidal thickness at various locations and age, AXL, gender and spherical equivalent (SEq).Results:Mean age of the subjects was 11.9 ± 3.4 years (range: 5–18 years). There were 62 Females and 74 males. The mean AXL was 23.55 ± 0.74 mm. Mean subfoveal choroidal thickness was 312.1 ± 45.40 μm. Choroid was found to be thickest subfoveally, then temporally. Age, AXL and SEq showed a significant correlation with choroidal thickness, whereas gender did not affect choroidal thickness.Conclusion:Our study provides a valid normative database of choroidal thickness in healthy Indian children. This database could be useful for further studies evaluating choroidal changes in various chorioretinal disorders. Age and AXL are critical factors, which negatively correlated with choroidal thickness.
