Philippine Journal of Ophthalmology 2022;47(2):92-96
Objective:
This study described the clinical profile of a four-generation Cebuano family with juvenile-onset
open-angle glaucoma (JOAG).
Methods:
Thisis a case series conducted in the out-patient department of Cebu Velez General Hospital. Thirtyeight (38) members in a four-generation family from the northern part of Cebu province were investigated.
General medical and ophthalmologic histories were taken. Complete ophthalmologic examination was done.
Results:
Forty-two (42%) percent of participants examined had increased intraocular pressures (IOP); 15 were
diagnosed with JOAG, one had ocular hypertension. There were more females than males affected. Mean age
when symptoms were first noted was 14.56 ±6.63 years and mean age at diagnosis was 16.3 ±7.84 years. The
most common initial symptom was rainbow or halos around lights (87.5%). Mean refraction was -3.09 ±2.54
diopters for both eyes. Mean IOP on examination was 24.56 ± 20.17 mmHg. Gonioscopy showed open angles
with flat iris plane. All affected participants underwent medical treatment and 69% needed surgical
interventions.
Conclusion
This family demonstrated the typical JOAG phenotype consisting of early age of onset, strong
family history with an autosomal dominant pattern of inheritance, myopia, open angles, and increased IOP
refractory to medical treatment.

Journal of Medicine University of Santo Tomas 2020;4(2):518-526
Purpose:
To conduct an evaluation of juxtapapillary choroidal thickness of patients suspected with
glaucoma obtained through spectral domain optical
coherence tomography (SD-OCT) and correlate it
with perimetry results.
Methods:
Design: Cross-sectional Study.
Population: 175 eyes diagnosed as “glaucoma
suspect” had standard automated perimetry (SAP)
to document the presence of functional glaucomatous damage using optimal near-point correction
using the Humphrey Visual Field Analyzer II, 30-2
or 24-2 SITA-standard program. SD-OCT imaging of
the retinal nerve fi ber layer (RNFL) was also done
to look for structural glaucomatous damage and in
using enhanced depth imaging of the optic nerve
and the Cirrus caliper tool, choroidal thickness was
measured at fi ve predetermined points temporal and
nasal from the optic nerve. The population was classifi ed into two groups: Group 1 are those with structural or functional glaucomatous damage (n=68)
and Group 2 were those without (n=107).
Results:
One-Way Multivariate Analysis of
Covariance was used in comparing the mean temporal and nasal choroidal thickness scores of the two
groups. There are no statistical differences in terms
of the mean temporal choroidal thickness (p=0.856)
and mean nasal choroidal thickness (p=0.734)
between patients with and without glaucomatous
damage. The mean temporal and nasal choroidal
thickness scores of the two groups at different juxtapapillary locations: 0 μm, 250 μm, 500 μm, 750
μm and 1000 μm away from the disc were also not
statistically different.
Conclusion
Results show that from this present
cohort of glaucoma suspect patients, juxtapapillary
choroidal thickness is not correlated with structural
and functional glaucomatous damage.

3.New classes of glaucoma medical treatment
Journal of the Korean Medical Association 2019;62(9):497-504
Glaucoma is a progressive degenerative disease of the optic nerve head, characterized by a specific pattern of axonal loss and visual field deterioration. This review aims at introducing the different novel pharmacologic agents for its treatment, as well as their mechanisms. Most glaucoma patients require lifelong care and individualized treatment. Intraocular pressure (IOP), which is regulated by aqueous humor production, outflow via the trabecular meshwork (parasympathomimetics only) and uveoscleral outflow pathways, is currently the only treatable target for glaucoma treatment. Conventional glaucoma medications are categorized as β blockers, α agonists, carbonic anhydrase inhibitors, parasympathomimetics, and prostaglandin analogues. The development of basic research-derived novel classes of pharmacologic agents features novel action mechanisms, which are different from those of conventional medications. New classes of recently approved or clinical trial-tested medications include Rho-kinase inhibitors, nitric oxide donors, adenosine agonists, and prostaglandin analogs targeting E-type prostanoid receptors, etc. Their integration and future development will facilitate the expansion and customization of therapeutic options.

PURPOSE: To investigate the underlying causes and clinical characteristics of patients referred with intraocular pressure (IOP) elevation. METHODS: We retrospectively reviewed the medical records of patients who were referred with IOP elevation from July 2016 to July 2017. Patients with baseline IOP ≥ 22 mmHg and those who were treated and followed up for 6 months were included. The prevalence rates of the underlying diseases that caused IOP elevation were evaluated and the clinical characteristics were compared between patients with primary and secondary glaucoma. RESULTS: A total of 127 patients were included (mean age, 59.3 ± 16.8 years; baseline IOP, 31.7 ± 10.5 mmHg). Among the study participants, 22.0%, 31.5%, and 46.5% had been diagnosed with ocular hypertension, primary glaucoma, and secondary glaucoma, respectively. Among the causes of IOP elevation, open-angle glaucoma (20.5%) had the highest prevalence rate among those with primary glaucoma and inflammation-related glaucoma (12.6%) was the most prevalent cause among those with secondary glaucoma. In a comparison between patients with primary and secondary glaucoma, the percentage of IOP reduction was not significantly different at 6 months after treatment (52.1% vs. 53.9%, p = 0.603). However, the rate of patients treated with drugs other than IOP lowering agents or who underwent surgery was significantly higher in the secondary glaucoma group compared with the primary glaucoma group (all p < 0.05). At 6-month follow-up, the secondary glaucoma group showed significantly higher improvement rates of visual acuity (p = 0.004), but had a larger proportion of patients with a visual acuity of less than or equal to finger count (p = 0.027). CONCLUSIONS: Treatment and visual outcome can vary depending on the underlying cause of IOP elevation. Therefore, a thorough examination for determining the cause of IOP elevation is recommended at the initial stage.

PURPOSE: To evaluate the incidence and risk factors for ocular hypertension (OHT) in traumatic hyphema within 7 days after trauma. METHODS: A retrospective case series study of 265 traumatic hyphema inpatients from 2010–2016. OHT was defined as intraocular pressure (IOP) that exceeded 21 mmHg using two consecutive measurements by a Goldmann applanation tonometer within 7 days after trauma. The subjects were divided into two groups (OHT group and non-OHT group). Age, sex, best-corrected visual acuity (BCVA), IOP, hyphema grade, presence of systemic disease, and past history of glaucoma were compared between the two groups. RESULTS: Of the 265 patients, 95 (35.8%) developed OHT after traumatic hyphema. Of those 95 patients, 70 (73.7%) developed OHT within 1 day after trauma; 18 (18.9%) developed OHT 2–3 days after trauma; and 7 (7.4%) developed OHT 4–7 days after trauma. Compared to the non-OHT group, the OHT group had a lower visual acuity (p = 0.018) and higher IOP (p < 0.001). In addition. if the hyphema grade was higher the incidence of OHT was significantly higher (p = 0.017). Using multivariate logistic regression analysis, the BCVA (p = 0.045) and hyphema grade (p = 0.006) were associated with the incidence of OHT in traumatic hyphema within 7 days after trauma. CONCLUSIONS: The incidence of OHT in traumatic hyphema within 7 days after trauma was 35.8%. The BCVA and hyphema grade were associated with the incidence of OHT within 7 days after trauma.

6.Functional Analysis and Immunochemical Analyses of Ca²⁺ Homeostasis-Related Proteins Expression of Glaucoma-Induced Retinal Degeneration in Rats
Experimental Neurobiology 2018;27(1):16-27
The retinal degeneration resulting from elevated intraocular pressure was evaluated through functional and morphological analyses, for better understanding of the pathophysiology of glaucoma. Ocular hypertension was induced via unilateral episcleral venous cauterization in rats. Experimental time was set at 1 and 3 days, and 1, 2, 4, and 8 weeks post-operation. Retinal function was analyzed using electroretinography. For morphological analysis, retinal tissues were processed for immunochemistry by using antibodies against the calcium-sensing receptor and calcium-binding proteins. Apoptosis was analyzed using the TUNEL method and electron microscopy. Amplitudes of a- and b-wave in scotopic and photopic responses were found to be reduced in all glaucomatous retinas. Photopic negative response for ganglion cell function significantly reduced from 1-day and more significantly reduced in 2-week glaucoma. Calcium-sensing receptor immunoreactivity in ganglion cells remarkably reduced at 8 weeks; conversely, protein amounts increased significantly. Calcium-binding proteins immunoreactivity in amacrine cells clearly reduced at 8 weeks, despite of uneven changes in protein amounts. Apoptosis appeared in both photoreceptors and ganglion cells in 8-week glaucomatous retina. Apoptotic feature of photoreceptors was typical, whereas that of ganglion cells was necrotic in nature. These findings suggest that elevated intraocular pressure affects the sensitivity of photoreceptors and retinal ganglion cells, and leads to apoptotic death. The calcium-sensing receptor may be a useful detector for alteration of extracellular calcium levels surrounding the ganglion cells.

Youn hye JO ; Bokjun JI ; Byung Joo CHO
Journal of the Korean Ophthalmological Society 2017;58(9):1074-1079
PURPOSE: To investigate the changes in intraocular pressure (IOP) and associated systemic factors over 7 years in a healthy Korean population. METHODS: This longitudinal study included healthy subjects with no history of ocular disease and who had been receiving health examinations seven years apart at the Konkuk University Medical Center, Healthcare Center. The participants completed lifestyle questionnaires and underwent general health examinations (blood pressure, height and weight, and blood biochemical tests) and ocular examinations including noncontact tonometry and fundus photography. Subjects with abnormal fundus photography findings and ocular hypertension were excluded. Changes in IOP and systemic factors over 7 years were analyzed. RESULTS: Of 524 possible subjects, 469 were enrolled (55 subjects were excluded: 50 due to abnormal fundus photography and 5 for missing data). The left eye was analyzed in all patients. In all subjects, initial IOP (mean 14.50 ± 3.14 mmHg) was not significantly different from final IOP (14.72 ± 3.38 mmHg) (paired t-test, p = 0.074). In male patients, the final IOP was significantly higher than the initial IOP (paired t-test, p = 0.035). Lifestyle questionnaire variables were associated with a final IOP that was significantly higher than the initial IOP (smokers, alcohol drinkers and less exercisers, paired t-test; p = 0.014, 0.010 and 0.024, respectively). A linear mixed-effects model analysis showed that the change in IOP was negatively associated with age, but this was not statistically significant. Changes in systolic blood pressure (SBP), body mass index (BMI), total cholesterol (T.Chol) and low density lipoprotein (LDL) were positively correlated with change in IOP. CONCLUSIONS: A linear mixed-model analysis showed IOP decreased with age but this was not statistically significant. Changes in SBP, BMI, T.Chol and LDL were significantly positively correlated with change in IOP.

Journal of the Korean Ophthalmological Society 2017;58(11):1234-1241
PURPOSE: To characterize the development of glaucoma, age of glaucoma onset, and treatments for patients with a facial port-wine stain (PWS). METHODS: We performed a retrospective analysis of the medical records of 58 patients (116 eyes) with facial PWS between January 2000 and August 2016. We noted patients' age at the initial examination, cup-to-disc ratio, corneal diameter, occurrence of ocular hypertension, development of glaucoma, age of glaucoma onset, and treatments. We compared the clinical features of eyes that developed glaucoma with those that did not develop glaucoma. Among those eyes with glaucoma, we investigated the differences between eyes that underwent surgery and those that did not undergo surgery. RESULTS: Among the 58 patients with a facial PWS (116 eyes), glaucoma was diagnosed in 38 patients (46 eyes; 39.66%). Of these, 26 patients (27 eyes; 58.69%) underwent glaucoma surgery. PWS-associated glaucoma usually developed by the age of 2 years (85.61%). In all patients, glaucoma developed on the same side of the face as the PWS. Of the 58 patients, 19 (32.76%) showed neurological symptoms, including seizures, developmental delays, intellectual disabilities, or hemiplegia, and 32 (55.17%) were diagnosed with Sturge-Weber syndrome. The mean number of glaucoma surgeries was 1.55 ± 0.93. The initial surgery included trabeculectomy (7 eyes), trabeculotomy (5 eyes), combined trabeculotomy/trabeculectomy (13 eyes), and aqueous drainage device insertion (2 eyes). The mean age at the first surgery was 35.14 ± 50.91 months. In 18 of 27 eyes (66.67%), the postoperative intraocular pressure (IOP) was controlled to below 21 mmHg, but 9 eyes (33.33%) showed elevated IOP and required a reoperation. CONCLUSIONS: PWS can be accompanied by ocular hypertension or glaucoma, so patients require regular ophthalmic examinations. When glaucoma occurs, it often does not respond to medication, making it difficult in some cases to control the IOP, so appropriate glaucoma surgery is necessary.

9.Glutamate receptor-mediated retinal neuronal injury in experimental glaucoma.
Zhong-Feng WANG ; Xiong-Li YANG
Acta Physiologica Sinica 2016;68(4):483-491
Glaucoma, the second leading cause of blindness, is a neurodegenerative disease characterized by optic nerve degeneration related to apoptotic death of retinal ganglion cells (RGCs). In the pathogenesis of RGC death following the onset of glaucoma, functional changes of glutamate receptors are commonly regarded as important risk factors. During the past several years, we have explored the mechanisms underlying RGC apoptosis and retinal Müller cell reactivation (gliosis) in a rat chronic ocular hypertension (COH) model. We demonstrated that elevated intraocular pressure in COH rats may induce changes of various signaling pathways, which are involved in RGC apoptosis by modulating glutamate NMDA and AMPA receptors. Moreover, we also demonstrated that over-activation of group I metabotropic glutamate receptors (mGluR I) by excessive extracellular glutamate in COH rats could contribute to Müller cell gliosis by suppressing Kir4.1 channels. In this review, incorporating our results, we discuss glutamate receptor- mediated RGC apoptosis and Müller cell gliosis in experimental glaucoma.
