APAO Macular and Nerve Fiber Layer Thickness in
Deprivational Amblyopia
Presenting Author: Yong-Woo Kim MD
Co-Author(s): Seong-Joon Kim MD PHD**, Young Suk Yu MD
Purpose: To evaluate the difference of macular and retinal nerve fiber layer (RNFL) thickness
between amblyopic and the fellow eye in patients with deprivational amblyopia.
Methods: Seventeen patients who underwent IOL implantation by a single surgeon after
the diagnosis of congenital cataract were recruited for OCT scans performed by Cirrus HD-
OCT (Carl-Zeiss Meditec; Dublin, Calif., USA). Results: No interocular differences were
found in the final spherical equivalents and the axial lengths. The macular thickness was
significantly greater in amblyopic eyes (P < .05), but the RNFL thickness was not. Conclusion:
Results suggest that the light deprivation may influence on the macular thickness.

Comparison of the iScreen to the MTI Photoscreener for the
Detection of Amblyopia Risk Factors in Children
Presenting Author: Noelle S Matta COT
Co-Author(s): David I Silbert MD*
Purpose: To evaluate the iScreen (IP) vs. the MTI photoscreener in detecting American
Association for Pediatric Ophthalmology and Strabismus (AAPOS)amblyopia risk factors
in children under age 7. Methods: Retrospective chart review of children with IP, MTI,
acuity, alignment, and cycloplegic refraction performed by one pediatric ophthalmologist.
Results: Of 150 children, 60% were found to have AAPOS amblyopia risk factors. Sensitivity
and specificity of IP were 84% and 78%; of MTI, were 78% and 78%. With newly
proposed revisions to AAPOS referral criteria, IP sensitivity and specificity were 86% and
75%; of MTI, were 80% and 80%. Conclusion: Both the iScreen and MTI are accurate in
the detection of amblyopia risk factors in children under the age of 7 and perform similarly.
Both perform well with proposed revisions to the AAPOS referral criteria.

APAO Outcomes of Secondary IOL Implantation in Aphakic
Children: A 5-Year Experience at a Tertiary Eye Care Center
Presenting Author: Muralidhar Ramappa MS
Co-Author(s): Archana Singh**, Sunita Chaurasia MD
Purpose: To report the results of secondary IOL implantation in eyes that underwent prior
cataract surgery during early infancy. Methods: Retrospectively analyzed 121 eyes of 71
children who had secondary IOL implantation between 2005 and 2011. Results: 67.63 ±
36.18 months; M:F: 47:24. Mean follow-up, 23 months; BCVA of ≥20/40 in 28% of cases,
≥ 20/41 and ≤ 20/100 in 31%, > 20/100 and ≤ 20/200 in 12%; better than 20/200 and ≤
20/400 in 6%; < 20/400 in 23%. Major complications included endophthalmitis in 1 case
and glaucoma in 3 eyes. Conclusion: Secondary IOL implantation is a safe and effective
means of rehabilitating pediatric aphakia.

APAO Longitudinal Assessment of Central Corneal
Thickness in Aphakic and Pseudophakic Pediatric Eyes
Under 2 Years of Age: Randomized Trial
Presenting Author: Abhay Raghukant Vasavada MBBS FRCS*
Co-Author(s): Mamidipudi Praveen DO**, Sajani K Shah MD, Vaishali Abhay Vasavada
MS**, Viraj A Vasavada MD*, Mayuri Khamar**, Rupal H Trivedi MBBS MS*
Purpose: Comparative evaluation of central corneal thickness (CCT) with/without IOL implantation
after bilateral cataract surgery at 4 years follow-up. Methods: A randomized
clinical trial of 60 children assigned to either contact lens/spectacle correction (aphakia, n
= 30) or IOL implantation (pseudophakia, n = 30) to assess CCT. Results: Mean CCT with
aphakia was significantly thicker than pseudophakia at 4 years (P < .001). In presence of
glaucoma, mean CCT in aphakia was significantly thicker (P < .01) while there was no
difference in pseudophakia at 4 years (P = .155). Conclusion: Eyes remaining aphakic
showed a larger increase in CCT than those receiving a primary IOL after cataract removal.

Comparison of Postoperative Complications in Infants
Undergoing Bilateral Simultaneous, Bilateral Sequential,
and Unilateral Intraocular Surgery
Presenting Author: Michael B Yang MD
Co-Author(s): Sheela L Masifi MS, Elizabeth D Agabegi MD
Purpose: We compared the incidence of postoperative complications after bilateral simultaneous
(BSI), bilateral sequential (BSEQ), or unilateral (UNI) intraocular surgery in
infants < 12 months of age. Methods: Twenty-one infants (42 eyes), 10 infants (20 eyes),
and 19 infants (19 eyes) had BSI, BSEQ, and UNI intraocular surgery, respectively. Results:
No eyes developed endophthalmitis. Both eyes of a single BSI cataract patient, no eyes
of any BSEQ patients, and 1 eye each of 2 UNI cataract patients developed pupillary block
glaucoma (P = .59). Retinal detachment occurred in the second eye of a BSI glaucoma
patient (P = .20). Conclusion: Bilateral PBG is a serious complication that should be considered
when contemplating BSI surgery.

The Predictive Value of Clinical Risk Index for Babies
Illness Severity Score for Severe ROP in Different Gender
and Racial Populations
Presenting Author: Michael B Yang MD
Purpose: We previously showed that race, gender, and Clinical Risk Index for Babies
subscore (CRIBSUB), in addition to birth weight, gestational age, and multiple birth status,
were independent predictors for ROP warranting surgery (ROPWS). Methods: We hypothesized
that CRIBSUB would continue as an independent predictor of ROPWS when analyzed
in subcategories of male-, female-, black-, or non-black-only infants and performed
multiple logistic regression on 357 infants. Results: CRIBSUB was an independent predictor
for ROPWS in eyes of non-black or male infants but not for black or female infants.
Conclusion: Black or female infants may have protective factors that lessen the impact
of illness severity on the development of ROPWS.

Long-term Outcome of Ahmed Glaucoma Valve Implantation
in Primary Congenital Glaucoma
Presenting Author: Walid Barakat MD**
Co-Author(s): Deepak Paul Edward MD, Sami Al Shahwan MD
Purpose:To evaluate long-term IOP reduction following Ahmed glaucoma valve implantation
(AGVI) in primary congenital glaucoma (PCG). Methods: Retrospective review. Primary
outcome measure was cumulative probability of success defined as IOP > 5 mmHg and
< 23 mmHg without serious complications and no additional glaucoma surgery. Results:
Fifty-eight eyes with PCG with previous glaucoma surgery underwent AGVI at 3.98 ± 3.12
years, with a preoperative IOP of 33 ± 5.63 mmHg, and follow-up of 62.5 ± 53.0 months.
The cumulative probability of success was 69% at 6 months, 62% at 1 year, and 56% at
2 years. Medication use remained unchanged (3.3 preoop to 2.56 at 2 years). Major complications
included encapsulation (10.3%), tube-cornea issues (10%), and hypotony (7%).
Conclusion: AGVI in PCG showed decreasing success over time with need for glaucoma
medications.

Quality of Life in Children With Glaucoma
Presenting Author: Benjamin L Freedman
Co-Author(s): Alice A Lin MD, Sarah K Jones, Sandra Stinnett, Kelly Walton Muir MD
Purpose: The evaluation of pediatric glaucoma therapies requires an understanding of
the factors influencing vision-related quality of life (VRQoL) as reported by children with
glaucoma. Methods: Fifty children with glaucoma were prospectively enrolled in an observational
study including VRQoL assessment. Results: Seven patients with mental disabilities
were unable to complete the VRQoL; of 43 children aged 5-17 years, mean VRQoL
was 24.9 ± 12.9 (scale 0-96, lower=better VRQoL) and was associated with visual acuity
in the better seeing eye (P = .03), not number of surgeries, number of eye drops, or specific
diagnosis (P = 0.6-0.9). The association was consistent across age groups. Conclusion:
VRQoL as reported by the child can be assessed across a wide age range of most children
with glaucoma and is influenced by visual acuity in the better-seeing eye.
