Background. Optic disk hemorrhage is known to be a risk factor for glaucoma progression. Cataract surgery by phacoemulsification results in large intraocular pressure fluctuations. We aim to investigate whether phacoemulsification is associated with optic disc hemorrhage in patients with glaucoma. Methods. This is a retrospective review of consecutive university clinic based glaucoma patients undergoing phacoemulsification alone, with at least 3 visits in the year before and at least 5 visits in the year following phacoemulsification. The presence of optic disk hemorrhage was evaluated with slit lamp biomicroscopy at each clinic visit prior to and following phacoemulsification. Results. We evaluated 158 eyes of 158 subjects; 15 (9.5%) had ODH noted at least once during the 2-year study period. Four eyes had ODH identified on postoperative day 1, for a cross-sectional prevalence of 2.5%. Fourteen ODH episodes were noted preoperatively versus 12 episodes postoperatively (P=0.68). Aspirin use was associated with ODH (P=0.015). Conclusions. Our cross-sectional study found a prevalence of ODH immediately after CE that was similar to other published rates, and our longitudinal study did not find an increase in ODH in the year after phacoemulsification when compared to the year prior to surgery.

BackgroundGlaucoma may cause physiological and behavioural circadian misalignment because of the loss of intrinsically photosensitive retinal ganglion cells, the primary receptors of environmental light. Although studies have suggested a high prevalence of depression in patients with glaucoma, it is unclear whether the association is independent of the light exposure profiles as an important confounding factor.MethodsIn this cross-sectional study of a community-based cohort of 770 elderly individuals (mean age, 70.9 years), glaucomatous optic discs were assessed using fundus photographs and depressive symptoms were assessed using the short version of the Geriatric Depression Scale (GDS). Daytime and night-time ambient light exposures were objectively measured for 2 days.ResultsDepressive symptoms (GDS score ≥6) were observed in 114 participants (prevalence, 14.8%) and glaucomatous optic discs were detected in 40 participants (prevalence, 5.2%). The prevalence of depressive symptoms was significantly higher in the group with glaucomatous optic disc than in the group without it (30.0% vs 14.0%, respectively; p=0.005). Multivariable logistic regression analysis adjusted for potential confounding factors, including daytime and night-time light exposures, revealed that the OR for depressive symptoms was significantly higher in the group with glaucomatous optic disc than in the group without it (OR 2.45, 95% CI 1.18 to 5.08; p=0.016).ConclusionsIn this general elderly population, glaucomatous optic disc was significantly associated with higher prevalence of depressive symptoms independent of a number of potential confounding factors, including daily light exposure profiles.

Pigment Dispersion Syndrome

Introduction: Pigmentary Glaucoma (PG) and Pigment Dispersion Syndrome (PDS) are two different spectrums of a single disease. Since the disease is seen in younger population and is rapidly progressive blinding disease, therefore early diagnosis and treatment will reduce the burden of the disease and improve the quality of life. Aim: To evaluate clinical characteristics of PDS and PG patients in eastern part of Uttar Pradesh. Materials and Methods: This was a two years (1st January 2018 to 31st December 2019) hospital‑based retrospective cross‑sectional study of patients who attended the glaucoma clinic. Diagnosis of PDS was made when they had normal optic disc, normal visual field {with or without increased Intra Ocular Pressure (IOP)} and at least two of the following three signs were found clinically: Krukenberg spindle, homogenous moderate‑to‑heavy (≥Spaeth 2+) Trabecular Meshwork (TM) pigmentation, and any degree of zonular and/or lenticular pigment granule dusting. Patients with PDS were diagnosed with PG, if they had two or more of the following findings: initial IOP >21 mmHg, glaucomatous optic nerve damage or glaucomatous visual field loss. Various parameters such as influence of demographics, IOP, Best‑Corrected Visual Acuity (BCVA), Central Corneal Thickness (CCT), Mean Deviation (MD), Visual Field Index (VFI %), spherical equivalent and clinical finding of anterior segment of study patients were analysed. Mean, standard deviation and percentage were calculated using GraphPad Instat version 3.0. Results: Among 40 patients, nine eyes of the six patients had myopia of ‑0.5D or greater, with mean refractive error of ‑3.55±4.72 spherical equivalent. The average baseline IOP in study patients (PDS+PG), was 30.21±11.42 mmHg. Twenty four (60%) patients, either in one or both eyes had glaucoma, secondary to PDS at the initial diagnosis. Thirty three (82.5%) patients had Krukenberg spindles. Homogeneous TM pigmentation was seen in all patients. Typical spoke‑like radial Iris Transillumination Defects (ITDs) were not observed in any of the patients except in one patient, who had isolated short slit‑like trans‑illumination defects in iris crypts. Conclusion: PDS patients with normal optic disc and visual field and raised IOP, should be started prophylactic treatment and needs to be monitored more closely. Thus, the finding of PDS in Indians should alert the ophthalmologist to look for glaucoma during the initial examination.

Abstract Background: To assess the prevalence and demographics of lower eyelid epiblepharon in Chinese preschool children and to evaluate its association with refractive errors.Methods: In this population-based, cross-sectional study, a total of 3,170 children aged 3 to 6 years from Beijing, China underwent examinations including weight, height, cycloplegic autorefraction and slit-lamp examination of external eyes. The prevalence of lower eyelid epiblepharon in preschool children was evaluated and its association with age, sex, body mass index (BMI), and refractive errors was analyzed using logistic regression analysis.Results: The prevalence of lower eyelid epiblepharon was 26.2%, which decreased with age, with prevalence in 3-, 4-, 5-, and 6-year-olds of 30.6%, 28.0%, 15.0%, and 14.3%, respectively. Boys had a higher risk of having epiblepharon than girls (OR = 1.41; 95%CI, (1.20-1.66)) and no significant correlation was detected between BMI and epiblepharon after adjusting for age and sex (p = 0.062). Epiblepharon was significantly associated with a higher risk of refractive errors, including astigmatism (OR = 3.41; 95% CI, (2.68-4.33)), myopia (OR = 3.55; 95% CI, (1.86-6.76)), and hyperopia (OR = 1.53; 95% CI, (1.18-1.99)). Conclusions: There is a high prevalence of lower eyelid epiblepharon in Chinese preschool children, particularly among boys and younger children. Preschoolers with lower eyelid epiblepharon are subject to a higher risk of developing astigmatism, myopia, and hyperopia, than those without. Increased attention should be paid to this eyelid abnormality in the preschool population.

Abstract Background: To assess the prevalence and demographics of lower eyelid epiblepharon in Chinese preschool children and to evaluate its association with refractive errors. Methods: In this population-based, cross-sectional study , a total of 3,170 children aged 3 to 6 years from Beijing, China underwent examinations including weight, height, cycloplegic autorefraction and slit-lamp examination of external eyes. The adjusted odds ratios (AORs) and 95% confidence intervals (CI) were calculated to evaluate. The prevalence of lower eyelid epiblepharon in preschool children and its association with refractive errors were analyzed. Results: The prevalence of lower eyelid epiblepharon was 26.2%, which decreased with age with 3-, 4-, 5-, and 6-year-old being 30.6%, 28.0%, 15.0%, and 14.3%, respectively. Boys had a higher risk of having epiblepharon than girls with ORs = 1.41 (95%CI, 1.20-1.66) and no significant correlation was detected between BMI and epiblepharon after adjustment of age and sex. Epiblepharon was associated with significantly higher risk of refractive errors including astigmatism (OR = 3.41; 95% CI, (2.68-4.33)), myopia (OR = 3.55; 95%CI, (1.86-6.76)), and hyperopia (OR = 1.53; 95% CI, (1.18-1.99)). Among astigmatic epiblepharon preschoolers, with-the-rule is predominant (80.9%) and epiblepharon severity was associated with astigmatism severity (p = 0.019). Conclusions: There is a high prevalence of lower eyelid epiblepharon in Chinese preschool children, particularly among boys and the youngers. Preschoolers with lower eyelid epiblepharon are subject to higher risk of developing astigmatism, myopia, and hyperopia, than those without. An increased attention should be paid to this eyelid abnormality in preschool population.

Background/Aims: Optic disc hemorrhage (DH) is an important glaucoma risk factor, and occurs in a wide intraocular pressure (IOP) range. We sought to characterize distinct clinical subtypes of patients with high- (HTDH) and low-tension DHs (LTDH). Methods: In this cross-sectional study, treated glaucomatous patients with DHs from two Glaucoma Services were consecutively enrolled. Disc photographs were evaluated for the presence of DH by two glaucoma specialists. After inclusion, patients were classified on HTDH (IOP≥16mmHg) and LTDH (IOP<16mmHg; median split). Clinical and ocular data from the time of DH detection were compared between groups. Results: One hundred thirty-three DH patients were included (LTDH=66 eyes; HTDH=67 eyes). Patients with LTDH were more often women than those with HTDH (77% vs 42%; p=0.030). There was also a trend for a higher prevalence of Asian descendants (24% vs 9%; p=0.058) and symptoms suggestive of vascular dysregulation (34% vs 14%; p=0.057) in LTDH patients. Eyes with LTDH also had worse visual field (VF) mean deviation index (p=0.037), higher prevalence of normal-tension glaucoma (NTG) diagnosis (46% vs 17%; p<0.001) and tended to have thinner central corneas (p=0.066). Conclusion: Patients developing DHs with treated IOPs in the low teens seem to more frequently fit in a profile represented by women, NTG diagnosis and greater VF loss. The presence of symptoms suggestive of vascular dysregulation and race also seem to differ between these two clinical subtypes. A closer optic disc surveillance is recommended for patients with the LTDH subtype, as they may develop DHs despite seemingly well-controlled IOP.

Optic Nerve Sonography

Introduction. Differentiating pseudopapilledema from papilledema which is optic disk edema and a result of increased ICP (intracranial pressure) is important and can be done with noninvasive methods like orbital ultrasound examination.Method. This was a cross-sectional study in which patients with optic nerve head swelling were referred for LP exam after optic nerve head swelling diagnosis confirmation and having normal brain imaging (CT scan). Before LP (lumbar puncture) exam the patients were referred for optic nerve ultrasound test of both eyes.Results. Considering 5.7 mm as the upper limit for normal ONSD (optic nerve sheath diameter), sensitivity and negative predictive value of optic sonography in diagnosis of pseudopapilledema are 100% for both eyes. Calculated accuracy validity of ONSD measurement in detecting pseudopapilledema is 90% for the right eye and 87% for the left eye.Conclusion. Our study demonstrated a close correlation between optic nerve sheath dilation on ocular ultrasound and evidence of elevated ICP with optic disk swelling. With the aid of noninvasive diagnostic tests we can avoid unnecessary concerns along with expensive and invasive neurological investigations while targeting the correct diagnosis in bilateral optic disk swelling. Our study showed optic nerve sonography as a reliable diagnostic method for further usage.
