ABSTRACT
Objective@#Toric intraocular lens implantation has been used to correct corneal astigmatism during cataract surgery. The study aimed to compare the visual outcomes between manual vs markerless toric intraocular lens implantation in astigmatic correction.@*Methods@#The medical records of patients at American Eye Center who underwent phacoemulsification by multiple surgeons with insertion of monofocal or multifocal toric lenses via manual marking and markerless method from 2010-2019 were reviewed.@*Results@#A total of 70 patients were included in the study. Results showed no significant difference in the following characteristics between manual and markerless method at one month and two months post-cataract surgery: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near vision acuity (UNVA), corrected near vision acuity (CNVA), refraction spherical equivalent. The UDVA, CDVA, UNVA, CNVA and astigmatism had significantly lower median/mean-rank at one and two months postoperatively compared to preoperative values.@*Conclusion@#In conclusion, our findings indicated that both manual-based and markerless systems effectively facilitated accurate placement of the toric IOL on the desired axis. Notably, there was no significant difference observed between the two methods. Both systems are straightforward to execute. In low-resource settings like the Philippines, the manual marking method can be employed when markerless guidance equipment is unavailable.

Objectives@#This study translated the Glaucoma Medication Adherence Self-Efficacy Questionnaire (GMASQ) and tested the reliability of Filipino-adapted GMASQ.@*Methods@#A Filipino-adapted GMASQ was developed using the guidelines recommended for translating a validated health-related questionnaire into a culturally-adapted one. The methods included: (1) forward translation, (2) back-translation, (3) review and modification, (4) pre-testing and cognitive interviewing, and (5) final version testing. The provisional questionnaire was pre-tested on 20 glaucoma patients to determine its value and correspondence, generating a final forward questionnaire. The final version was administered to 48 patients. Its reliability was determined by computing for the Cronbach’s α for each item, per section, and overall. An item was removed if the α was <0.7.@*Results@#Eleven (11) pre-test subjects (55%) preferred the Filipino-adapted questionnaire, 6 (20%) had no preference, and 3 (25%) preferred the source questionnaire. The provisional Filipino-adapted GMASQ proved to be acceptable and with no changes made, the questionnaire was marked as the final version. The medication adherence self-efficacy scale showed Cronbach’s α of > 0.8 for all items with a section α = 0.84. The eye-drop technique had an α > 0.7 for each item and a section α = 0.80.@*Conclusion@#This study provided preliminary evidence of the feasibility, acceptance and reliability of the Filipino GMASQ.

Objectives@#We described the demographic and clinical profiles of patients with carotid-cavernous fistula (CCF), determined the prevalence of increased intraocular pressure (IOP), and described the IOP outcomes after endovascular treatment.@*Methods@#This was a single-center, retrospective review of records of patients with clinical signs and radiologic evidence of CCF from January 2012 to December 2017. Outcome measures included the prevalence of increased IOP in those with CCF, mean and range of IOPs, average number of IOP-lowering medications needed, and percentage of eyes with normal, controlled, and uncontrolled IOP before and after endovascular intervention. @*Results@#Ninety-six (96) eyes of 92 patients with radiologic evidence of CCF on 4-vessel cerebral angiography were included. Fifty-nine (59) percent were between the ages of 20 to 39 years. Majority (65%) were males. Direct CCFs accounted for 70% of cases. Increased IOP was the third most common ocular sign with a prevalence of 78%, ranging from 10 to 56 mmHg (mean 20.3 ± 8.0). The average number of antiglaucoma medications for IOP control was 2. Eleven (11) underwent definitive management for CCF. Post-treatment, 33% of 13 eyes had normal, 27% controlled, and 40% uncontrolled IOPs.@*Conclusion@#There was a high prevalence of increased IOP in patients with CCF. Those who did not achieve IOP control should be referred for endovascular intervention to prevent serious complications, including secondary glaucoma.

Intraocular PressureABSTRACT
@#Background. Childhood glaucoma is a rare multifactorial disease with limited information regarding the demographics and characteristics in the Filipino setting. It can be categorized via the Childhood Glaucoma Research Network Classification scheme. Objective. Determine the clinical classification of patients diagnosed with childhood glaucoma in the ophthalmology service of a government tertiary hospital in Manila, Philippines. Methods. Medical records of all patients ≤16 years-old referred to Glaucoma Section of Philippine General Hospital from January 2015 to December 2017 were reviewed retrospectively and classified. Results. One-hundred four (104) eyes in 77 children were classified. Glaucoma associated with acquired conditions was the most prevalent in 44.2% of the patients with trauma consisting of 19.5% of all patients. Primary childhood glaucoma consisted of 15.6% and juvenile open-angle glaucoma was diagnosed in 5.2%. Glaucoma following cataract surgery was noted in 7.8% of patients. Trabeculectomy was the primary surgical intervention in 22.2% of eyes, with 78.9% of eyes reaching an IOP control of <21mmHg on final follow-up. Conclusion. Glaucoma associated with acquired conditions was the most common childhood glaucoma in the patient population. Trabeculectomy was the most common surgery done. Trauma was the most prevalent cause of glaucoma from acquired conditions.
