Methods: Case records of all patients seen at the pediatric ophthalmology clinic of UP-PGH from January 1, 2000 to August 31, 2003 were reviewed. Included were patients less than 21 years old diagnosed with cataract not associated with trauma. Cases were classified as to presumptive etiology: idiopathic, familial, or secondary to a systemic or an ocular disorder. Results: The cause of cataract was identified in 37.6 percent of the 218 cases reviewed. Rubella was the leading cause (20.5 percent), followed by suspected rubella infection (8.2 percent). There were 2 cases of varicella and 1 case of cytomegalovirus (CMV) infections. Down syndrome and Lowe syndrome had one case each. Three cases (1.4 percent) were familial. Cataract was idiopathic in 133 cases (61.0 percent). Conclusion: The pattern of childhood cataract in this study is typical of a developing country where rubella infection is the major cause.

Objective: To present 3 cases of Möbius sequence exposed in utero to misoprostol and discuss their clinical presentations, etiopathogenesis, and management. Methods: Medical records of 3 patients with Möbius sequence and prenatal exposure to misoprostol were reviewed. Clinical findings were compared with those reported in the literature. Results: Lack of facial-muscle movement, lagophthalmos with secondary exposure keratitis, decreased ability to crease forehead, and shallow nasolabial fold imply facial-nerve dysfunction. Small- and large-angle esotropia and apparent orthotropia with abduction limitation showed varying degrees of abducens nerve involvement. Two patients had early prenatal exposure to misoprostol during the first 3 months of gestation. Conclusion A history of misoprostol exposure should be routinely elicited from parents of children with Möbius sequence. Associated deficiencies in Möbius sequence and its variants require a multidisciplinary approach.

In 2004, the University of the Philippines Manila published the Philippine Guidelines on Periodic Health Examination (PHEX): Effective Screening for Diseases among Apparently Healthy Filipinos. 1 The document was envisioned to “contribute… to the quality and efficiency of health care and health maintenance for all Filipinos… It was an appeal for rational medical decision-making, and an important step toward “equitable distribution of health and health resources.” The guidelines were prepared by designated task forces, with vision disorders, specifically vision impairment, and glaucoma identified as areas of interest. PHEX recommendations were drafted using standardized principles and a common protocol, with each statement undergoing four phases of development: (1) preparation of the evidence- based draft; (2) en banc meeting that gave panelists a chance to assess and revise the draft, where issues of feasibility, resource limitations, value judgment, and experts’ opinions were taken into account. A consensus was declared when at least 75% agreed on a recommendation; (3) for unresolved issues, modified Delphi technique was employed by correspondence until a consensus was reached or a maximum of three circulations were accomplished. If still unresolved, the issue was labeled as such and included in the final draft; (4) lastly, a public forum was conducted before the final draft was written. In this manner, the recommendations for Screening for Visual Impairment were written by the Task Force for Vision Disorders.

Spontaneous consecutive exotropia (SCXT) in conservatively managed accommodative esotropia is not widely discussed. The author presents a case series of 4 patients with SCXT describing patient characteristics and possible risk factors. Management modifications based on this series are proposed. Four cases of patients who initially presented with accommodative esotropia and later developed SCXT are presented. The age range at presentation was between 4 months to 3 years, with total follow-up ranging between 8–15 years. All four cases presented with esotropia on or before the age of 3 years, with initial hyperopia ranging between +1.50 to +4.25. The SCXT occurred between ages 2–7 years. Possible risk factors identified include amblyopia, dissociated vertical deviation, rapid control of esodeviation, inferior oblique overaction, and poor follow-up during the course of their strabismus. The author recommends earlier tapering of hyperopia correction following initial control with full cycloplegic refraction. Identified risk factors should alert the specialists to be wary of SCXT.

Objectives: Refractive changes have been studied after muscle surgery in literature but most results are inconsistent. It has been postulated that changes in corneal tension after muscle surgery may cause a change in corneal curvature resulting in the change in refraction postoperatively. This study investigated changes in corneal topography and clinical refraction after horizontal rectus muscle surgery. Methods: Twenty-one eyes of 13 patients underwent horizontal rectus muscle surgery via limbal approach. Manifest refraction, cycloplegic refraction, and corneal topography were measured preoperatively, and postoperatively at day 1 and weeks 1, 2, 4 and 8. The proportion of subjects with at least 0.5 D change from preoperative measurements and the proportion of subjects that needed new prescription postoperative were also computed. Analysis of the results were done using the Friedman test to identify significant differences among measurements at different time periods with post-hoc analysis utilized to identify specific time periods with significant changes from preoperative measurements. Results: Mean corneal keratometry, horizontal, vertical, and oblique astigmatism, obtained topographically showed no significant difference from preoperative measurements. The statistically significant difference in corneal astigmatism in the recession group at day 1, week 4 and week 8 postoperatively was not confirmed when converted to power vectors in both vertical/horizontal (J0) and oblique (J45) astigmatism. Clinical refraction showed a transient myopic shift in spherical equivalent, statistically significant only on postoperative day 1 in the recession group. There was no statistically significant difference in clinical astigmatism. There was ≥ 0.5 D change in spherical equivalent in 60% in both study groups by the end of follow-up. The shift in J0 was more than 10% in the recession group. More than fifty percent (52.4%) needed new prescription for glasses. Conclusion No statistically significant change in corneal topography and clinical refraction following horizontal rectus muscle surgery were found. Patients should still be refracted at least 2 weeks postoperatively to check if there is a need for change in prescription glasses to improve alignment and/or improve vision.

The ongoing global COVID-19 pandemic triggered a series of events that resulted in the disruption of the delivery of various certifying examinations including that which was given by the Philippine Board of Ophthalmology (PBO). This paper shares the experience of the PBO using digital technology in administering its first ever online delivery of its certifying examinations. Online platform requirements used for delivering the examination are enumerated, online proctoring described, as well as the conduct of oral panel examinations and skills evaluation via video submission. Challenges encountered, feedback reported by both examinee and examiner, lessons learned from this endeavor, and future directions are discussed.

Background and Objective: The Philippines does not have a national congenital rubella syndrome (CRS) surveillance or registry. Regular monitoring of CRS cases in hospitals, including in a Philippine tertiary hospital, helped in the past to provide clinico-epidemiologic data on CRS. This study aimed to continue providing clinico-epidemiologic data on CRS cases seen in the Philippine tertiary hospital from 2009-2012 and 2019-2022 and compare the cases seen from said timelines. Methods: A cross-sectional study was used, employing chart review of patients newly diagnosed with CRS from 2009-2012 and 2019-2022 in the Department of Ophthalmology and Visual Sciences at the Philippine tertiary hospital. Results: Forty-two patients newly diagnosed with CRS from 2009-2012 and 2019-2022 were included. Only 14 (33%) were serologically-confirmed cases (albeit qualitatively). Median age (first and third interquartile ranges) at consult was 1 year (0.4, 2.5). Twenty-four (57%) patients had maternal history of rashes and/or fever. Trimester of pregnancy when mother became symptomatic was not significantly correlated with chief complaint (p=0.20) and numbers of ophthalmic (p=0.68) and systemic manifestations (p=0.32). Cataract was the most common ophthalmic manifestation present in 40 (95%) patients. Twenty-six (62%) patients had other associated systemic findings of which hearing loss was the most common. Only 29 of 40 patients with cataract underwent lensectomy, with 23 patients having poor visual prognosis prior to surgery (5 with nystagmus alone, 10 with nystagmus and strabismus, and 8 with strabismus alone). Discussion: Using ophthalmic manifestations as primary indicator, this study provided an update on the CRS cases in the country. Laboratory confirmation remains a challenge in diagnosing CRS as the tests are costly and not widely available. There was increase from 2009-2012 compared to 2019-2022 in number of patients who underwent surgical treatment for cataract but visual outcomes were suboptimal due to delay in consultation. Although there was a decrease in number of CRS cases seen in the Philippine tertiary hospital, this cannot be attributed to increased rubella-containing vaccine (RCV) coverage alone. Conclusion Provision of data from individual hospital-based studies similar to this highlights the need for a national CRS surveillance system or registry. This can better gauge the burden of CRS and identify the gap in RCV coverage.

Objective: To compare the postoperative alignment of patients surgically corrected for esotropia or exotropia 6 weeks and 6 months after surgery. Method: This retrospective study reviewed clinical records of patients who underwent horizontal muscle surgery at the University of the Philippines-Philippine General Hospital from 2010 to 2014. The changes in alignment from 1 week to 6 weeks and from 1 week to 6 months after surgery were compared for overcorrection, undercorrection, and adequate correction groups. ANOVA and Pearson correlation were used. Results: Twenty two esotropia and 10 exotropia patients were included. Overcorrected esotropia patients had an esotropic change in alignment (15.50+13.44 PD after 6 weeks, p=0.026; 25+18.38 PD after 6 months, p=0.008). Under corrected esotropia patients had an exotropic change in alignment (-1.25+5.91 PD after 6 weeks, p=0.026;-4.38+14.16 PD after 6 months, p=0.008). Undercorrected exotropia patients had an esotropic change in alignment (6.67+6.35 PD after 6 weeks, p=0.028; 6+9.85 PD after 6 months, p=0.024). The presence of vertical deviations in esotropia caused an exotropic change in alignment after 6 months (p=0.03). Conclusion Although an exotropic drift is more commonly reported, fusional vergences may account for postoperative alignment changes towards orthotropia.

Children with weak or absent capsular support requiring lens removal and intraocular lens implantation present as one of the more challenging cases in pediatric ophthalmology practice. The authors present a case series with postoperative follow-up of at least five years after retropupillary fixation of iris-clipped lenses. All cases had improved visual acuity with only minor focal iris atrophy as complication in one case. Retropupillary fixation of iris-clipped IOL should be included in an ophthalmologist's armamentarium when operating on cases with weak or absent capsular support.
