OBJECTIVE: To describe the demographic and clinical characteristics of patients with glaucoma managed at private and government institutions in the Philippines between 2009 and 2014.

METHODS: A research team from two private and two government institutions in the Philippines reviewed the case records of 1246 patients seen who met the following criteria: intraocular pressure of >21 mmHg, optic nerve and nerve fiber layer abnormalities, and visual field defects. For bilateral cases, we selected the eye with worse glaucoma parameters.

RESULTS: There were 600 and 646 patients in the private and government groups (mean age at presentation, 60.51 and 55.88 years), respectively, with the majority being Filipino (91%). Patients with visual acuity (VA) of 20/20 to 20/40 were more frequently observed in private centers (58.7% vs. 41.3%), while a VA worse than counting fingers was more frequently observed in government centers (66.1% vs. 33.9%). Within-group analysis showed that primary angle-closure glaucoma was the most frequent glaucoma subtype in both private (27.3%) and government institutions (37.8%). In between-group analysis showed the following to be more common in private than government centers: primary open-angle glaucoma (61.3% vs. 38.7%), normal-tension glaucoma (63.9% vs. 36.1%), ocular hypertension (92.3% vs. 7.7%), and glaucoma suspects (80.4% vs. 19.6%) while government institutions registered a larger number of primary angle-closure glaucoma (59.8% vs. 40.2%) and secondary glaucoma (70.3% vs. 29.7%) cases. Medical treatment using a single drug and multiple drugs was employed for 245 (23%) and 825 (77%) patients, respectively. Within-group analysis showed that laser iridotomy and trabeculectomy were the most commonly performed laser and surgical procedures in both institution types.

CONCLUSION: There is a contrasting profile of glaucoma between clinical institutions in the Philippines with openangle glaucoma being more predominant in private centers while closed-angle glaucoma and secondary glaucoma being more frequent in government centers. Our findings may provide important preliminary information that can aid future health studies or training programs.

Objective: To identify the risk factors for conjunctival tube erosion (CTE) in eyes implanted with Ahmed® glaucoma valve (AGV) device Method: This is a retrospective study conducted at a private eye institution. Medical records of patients who underwent AGV implantation surgery from January 2004 to December 2013 were reviewed. Eyes with at least 24 months of follow-up and complete records were included. Several variables from the pre-, intra-, and postoperative periods were collected. The primary outcome was development of CTE after AGV surgery. Univariable logistic regression and multivariable analysis were employed. Results: Forty-six (46) eyes of 45 patients were included in the study. The mean follow-up was 50.2 months (range: 24-140 months). Eight (8) eyes developed CTE (17.4%). Univariable logistic regression analysis identified female gender (P =0.064), presence of diabetes (P =0.083), prior intraocular surgeries (P =0.09), and postoperative use of antiglaucoma medications (P =0.086) to be marginally significant risk factors for CTE. On multivariable analysis, only female gender (OR=15.4, P =0.033) and diabetes (OR=14.1, P =0.031) were found to be significantly associated with CTE. Conclusion Risk factors for CTE following AGV implantation include female gender and presence of diabetes.

In this day and age of research and constantly improving methods of research conduct and protocols, policies are determined, to a large part, by the results of these researches, most of which are numbers. So in addressing the growing need to prevent blindness from Retinopathy of Prematurity (ROP), experts worldwide, in at least 2 major landmark studies and 4 World ROP Congresses, agreed on the definitions of high-risk criteria, with emphasis on timely referral. These were all meant to guide the pediatricians in referring premature babies for ROP screening. These efforts were meant to drive home a very important point: the occurrence of visually-debilitating stages of ROP are preventable. The incidence of blindness from ROP is quite small, but nonetheless, catastrophic to the patient. To speak of those numbers is not my purpose today. My purposes are to put a face and a voice to those who are “the tiny number … the small incidence” crying out from the outer edges of bar graphs, and to remind everyone that that tiny number of blind and nearly blind children are people with lives to live, and futures to look forward to, just like the rest of us. Certainly, opening that golden window of opportunity is the most important thing that one can do for the premature baby at risk of developing ROP. One is not born with ROP. No one wants to have it. No parent will want his child to have it. And if one does have it, one must be protected from the deleterious consequences of ROP. This will happen only if everyone concerned will just do what they have to do. Screening of a high-risk baby by an ophthalmologist cannot be done without a referral from the attending pediatrician. The tireless efforts of neonatologists and pediatricians in keeping the premature babies alive and managing all their life-threatening conditions are truly laudable. However, we must insist that sight is just as important. We must insist that high-risk babies be referred to an ophthalmologist for ROP screening. The importance of a wholistic approach in the management of a premature baby cannot be overemphasized. Quality of life should be a primary consideration when it comes to any situation where something has been compromised. To drive home a point, please do this: Imagine your child blind. Then think of everything that a blind child will miss in his life. Think of all the difficulties that the blind child will encounter in his entire life. Think of all the difficulties and the heartaches for the parents of the blind child. Then think of how this blind person will be when the doting parents who took care of him will one day no longer be around. A parent of an ROP blind child once said “To a parent there are no statistics. My child is always 100%.” And finally, think about these wise words from Nelson Mandela: History will judge us by the difference we make in the everyday lives of children.

Neuroretinitis is an inflammatory optic neuropathy with a classic fundoscopic appearance of optic disc swelling and hard exudates on the macula in a star formation. It can be a manifestation of systemic, infectious or autoimmune disease. In nearly half of cases, the etiology is idiopathic. This review aims to summarize the clinical presentation, fundoscopic mimics, etiologies, investigation, and treatment of neuroretinitis. Cat-scratch disease, the most common cause of infectious neuroretinitis, and recurrent idiopathic neuroretinitis, which can cause ocular morbidity, are discussed in detail.

Objective: To identify maternal and infantile risk factors for retinopathy of prematurity (ROP) among preterm infants screened in St. Luke’s Medical Center, Quezon City (SLMC-QC) from 2014-2017. Methods: This was a retrospective study that included the ROP databank of the Eye Institute and the Research and Biotechnology Group of St. Luke’s Medical Center, Quezon City from 2014 to 2017. This study included medical records of all premature infants screened for ROP and excluded those who had incomplete data or other ocular pathologies other than ROP. Risk factors were analyzed using univariate analysis. Odds ratio (OR) and 95% confidence interval (CI) were also calculated with significant P value set at <0.05. Results: Among the 455 infants screened for ROP, 118 (25.9%) had any stage of ROP while 23 (5.0%) had treatment-warranted ROP (TW-ROP). Univariate regression analysis showed that the top 5 infantile risk factors associated with any stage of ROP and TW-ROP were low birth weight (97.5% and 100%, respectively), prematurity (87.3% and 100%, respectively), history of blood transfusion (21.2% and 13%, respectively), sepsis (21.2% and 17.4%, respectively), and oxygen supplementation (16.1% and 8.7%, respectively). After multivariate analyses, the most important adjusted risk factors associated with any stage of ROP include low birth weight (OR 52, CI 16.20166.96, P =0.001), prematurity (OR 25.73, CI 14.10-46.95, P =0.001), and history of blood transfusion (OR 8.79, CI 4.08-18.96, P =0.0001). Conclusion The most significant infantile risk factors associated with any ROP include low birth weight, prematurity, and history of blood transfusion. There were no significant probable maternal risk factors. Timely ROP screening is recommended especially among infants with any of these risk factors in their profile.

Objective: To validate WINROP, a web-based screening tool for retinopathy of prematurity (ROP), in the detection of any-stage ROP or treatment-requiring ROP among Filipino preterm infants screened for ROP from January 2013 to April 2017. Methods: Charts of preterm infants who were screened for ROP at a tertiary hospital from January 2013 to April 2017 were reviewed. Birth date, gestational age, birth weight, and weekly postnatal weight measurements were collected and entered into WINROP. The number of infants that were tagged by WINROP with alarm signals for any-stage ROP or treatment-requiring ROP were noted and compared with actual ROP screening findings. The sensitivity, specificity, positive predictive values (PPV), and negative predictive values (NPV) of the WINROP application in predicting any-stage ROP and treatment-requiring ROP were computed. Results: Charts of 138 preterm infants were included in the study. Sixty-four (64) had a chart diagnosis of anystage ROP and 13 had treatment-requiring ROP. WINROP tagged 77 and 10 preterm infants with any-stage ROP and treatment-requiring ROP, respectively. The sensitivity and specificity rates of WINROP for detecting any-stage ROP were 63.5% (95% CI: 51.5% - 74.2%) and 78.1% (95% CI: 65.7% - 87.1%), respectively. While the sensitivity and specificity rates at identifying treatment-requiring ROP were 76.9% (95% CI: 45.9% - 93.8%) and 46.4% (95% CI: 37.5% - 55.5%), respectively. Conclusion WINROP is fairly sensitive and specific in predicting any-stage ROP but has fair sensitivity and poor specificity in predicting treatment-requiring ROP. WINROP may aid in ROP prediction, but regular screening of preterm infants at risk for ROP based on current criteria remains to be the standard of care.

Objective: To report the epidemiology of canalicular lacerations and surgical outcomes of canalicular laceration repair with Mini-Monoka® (FCI Ophthalmics, Issy-les-Moulineaux, Cedex, France) intubation. Methods: This is a retrospective interventional case series of patients who underwent Mini-Monoka® intubation in the repair of canalicular laceration from 2010 to 2015 at a tertiary state-owned hospital in Manila, Philippines. Patient demographics, surgical outcomes, and complications were analyzed. Results: Fourteen patients (12 males and 2 females) underwent Mini-Monoka® intubation for monocanalicular laceration. The mean age at presentation was 27 years (range, 16-47 years). The mean duration of follow-up was 2.92 years (range, 1.28-6.15 years). Canalicular patency was achieved in 12 out of the 14 patients (86%). None of the 12 patients experienced epiphora following stent removal resulting in a functional success rate of 100%. Two patients had punctal slitting (14%). Premature stent loss occurred in 2 out of the 14 patients (14%). Conclusion Mini-Monoka® intubation is effective in maintaining the long-term anatomical patency of the lacerated canaliculus. It is a simple and minimally invasive procedure making it a safe and reasonable alternative to the traditional methods of canalicular repair.

Objective: To measure the ciliary sulcus diameters (CSD) in phakic eyes of adult Filipinos using ultrasound biomicroscopy (UBM). Methods: This was an observational, cross-sectional study involving Filipino patients recruited from the Outpatient Department of Makati Medical Center, Philippines from September 2006 to December 2006. Vertical and horizontal CSDs in phakic eyes were measured using a UBM Scan 1000 (Ophthalmic Technologies Inc., Toronto, Ontario, Canada). Three repeated measurements of each meridian were taken and averaged. The average CSD for each eye was computed as the average of the horizontal and vertical CSDs. Student’s t-test was used to analyze data. Results: Seventy-one (71) patients (142 eyes) were included in the study. Mean CSD measurements were as follows: horizontal CSD = 9.76 ± 0.42 mm; vertical CSD = 10.00 ± 0.48 mm; average CSD = 9.88 ± 0.47 mm. There was a significant difference between the means of the vertical and horizontal CSD measurements (P<0.01). There was no significant difference in the mean CSD measurements of the right and left eyes (P= 0.50). Conclusions In this cohort of adult Filipino patients, the UBM-measured vertical CSD is significantly greater than the horizontal CSD. Establishment of CSD measurements of adult Filipino eyes may be helpful in selecting appropriately-sized intraocular lenses for ciliary sulcus implantation.

Ischaemic optic neuropathy (ION) is the commonest adult optic neuropathy encountered in Southeast Asia and will increase in incidence with an ageing population. It occurs in two forms: arteritic and non-arteritic. The latter variety being by far the commoner encountered in the region and presenting as an anterior optic neuropathy with optic disc swelling. The clinical presentation of both varieties is described with particular reference to the hyperaemic disc appearance of the non-arteritic disease as opposed to the ischaemic, pale, swollen, infarcted disc seen in arteritic anterior ION. Essential visual field defects found in both varieties are emphasized; the prognosis and treatment are discussed. Pathological specimens are also illustrated. Posterior ION is briefly mentioned being a diagnosis of exclusion. The anatomy, especially the blood supply of the optic nerve head, is discussed along with its role in the production of the different varieties of ION.

Objectives: The primary goal of this study was to determine the relationship between diabetic peripheral neuropathy and retinal nerve fiber layer (RNFL) thickness among elderly Filipinos with type 2 diabetes mellitus. Methodology: This was a cross-sectional study involving 106 subjects aged 60 years or older with type 2 diabetes mellitus recruited from the General Medicine and Diabetes Clinics of a tertiary government hospital. The diagnosis of peripheral neuropathy was made by performing a 10-gram monofilament test. Peripapillary retinal nerve fiber layer thickness was measured using the optic disc cube 200 x 200 protocol of the Cirrus® HD-OCT. T-test was used to compare RNFL thickness in those with and without peripheral neuropathy. The effects of age, sex, duration of diabetes, presence or absence of peripheral neuropathy, and retinopathy status on global and quadrantal RNFL thickness was assessed using multivariate analysis. Results: Compared to subjects without peripheral neuropathy, significant thinning of the superior (P=0.011), inferior (P=0.004), and global (P=0.008) RNFL thickness were observed in subjects with peripheral neuropathy. There were no significant differences in RNFL thickness in the temporal (P=0.211) and nasal (P=0.263) quadrants between the 2 groups. Multivariate regression analysis revealed that presence of peripheral neuropathy has a significant effect on their superior (P=0.036), inferior (P=0.010), and global (P=0.024) RNFL thickness. Other factors such as age, sex, duration of diabetes, and retinopathy had no effect on global and quadrantal RNFL thickness. Conclusion RNFL thinning in the superior, inferior, and global indices on optical coherence tomography has a significant correlation with diabetic peripheral neuropathy
