Acute angle-closure related with choroidal metastasis from lung adenocarcinoma: A case report and literature review.

Changes in the RNFL

Bilateral acute primary angle closure attack, though possible, is a rare condition. Secondary causes such as psychotropic drugs (topiramate), snake bite, and general anesthesia have been implicated in various case reports. We hereby describe a rare case of bilateral simultaneous acute angle closure attack secondary to microspherophakia and lens subluxation in a young lady with Weill–Marchesani syndrome, which was initially misdiagnosed as acute primary angle closure glaucoma. This case highlights the importance of eliciting proper history and paying attention to general examination findings to rule out secondary causes in a young patient with bilateral acute angle closure glaucoma.

To investigate differences between preoperative target refraction and postoperative spherical equivalent refraction in eyes with the first attack of acute angle closure glaucoma before and after surgery. We retrospectively examined eyes of 36 patients who suffered the first attack of acute primary angle closure after undergoing cataract extraction and intraocular lens implant. We measured keratometric values (K1, K2) due to medical therapy for high ocular tension and the mean time interval until surgery. We compared the axial length, expected diopter, logMAR visual acuity, K1, K2, refractive spherical equivalent, and intraocular pressure (IOP) before and 6 months after surgery. The average preoperative IOP was 51.3 ± 9.0 mmHg, but it decreased to 14.8 ± 3.6 mmHg after surgery. No corneal edema was observed after surgery. The average axial length was 22.12 ± 1.03 mm and there was no significant change in keratometric values, which were 7.72 ± 0.33 mm (K1) and 7.51 ± 0.31 mm (K2) before surgery and 7.67 ± 0.33 mm (K1) and 7.49 ± 0.29 mm (K2) after surgery. Similarly, no significant difference was observed in average preoperative target refractive error (-0.57 ± 0.53 D) and average postoperative refractive spherical equivalent (-0.67 ± 0.97 D). The inability to accurately determine preoperative refractive error due to corneal edema or other complications is a concern during the first attack of acute angle closure glaucoma. However, our results indicate that no differences should be expected between preoperative refractive error and postoperative refractive spherical equivalent.

Acute Angle-Closure Attacks Are Uncommon in Primary Angle-Closure Suspects after Pharmacologic Mydriasis: The Zhongshan Angle-Closure Prevention Trial

There is a lack of information about long-term results of chronic angle closure glaucoma following an acute primary angle closure attack in Caucasian patients. The aim of the study was to report morphological and functional long-term data of chronic angle closure eyes following a monolateral primary angle closure attack and to provide a comparison with their fellow eyes. Observational retrospective case series. Fifty-seven consecutive patients (114 eyes) underwent long-term follow-up analysis. Patients underwent ophthalmic assessment more than 5years since the angle closure attack. Intraocular pressure, best-corrected visual acuity, angle assessment, vertical C/D ratio and standard automated perimetry were the main outcome measures. Comparisons were made between angle closure attack eyes and fellow eyes and between phakic and pseudophakic eyes. Mean follow-up time was 5.86±1.19years. A significant greater damage in the angle closure eyes compared with fellow eyes in both structural (mean C/D 0.61 ± 0.16; P < 0.001) and functional (mean deviation: -7.98 ± 6.46 vs. -4.83 ± 4.95 dB; P < 0.001) terms was present. Mean IOP was 13.44 ± 2.78 and 13.89 ± 2.60 mmHg in angle closure and fellow eyes (P = 0.11). Thirty of 57 (53%) fellow eyes developed chronic angle closure (mean deviation: -7.74 ± 5.21 dB) even if prophylactic iridotomy was promptly performed. Our study prompts ophthalmologists to closely follow patients after an APAC attack to prevent potential glaucoma damage in both APAC and fellow eye.

Acute primary angle closure attack is an ophthalmological emergency. The aim of this study was to describe the cases diagnosed in the Emergency Department, by correlating the initial complaint with the Manchester triage level and ultimately the time needed until ophthalmological evaluation and iridotomy. Retrospective analysis of the electronic medical records of patients with acute primary angle closure attack that attended the Ophthalmology Emergency Department of our tertiary center between January 2010 and December 2020. Overall, 2228 Emergency Department episodes coded with the diagnoses glaucoma or ocular hypertension were retrieved, followed by screening of each episode for correct identification of true acute primary angle closure attacks. Clinical data was gathered, including Manchester triage level, presenting complaint, intraocular pressure at presentation, first medical specialty that observed the patient, time until observation by Ophthalmology and time until laser iridotomy. Among the 120 patients identified, 84 (70%) were female and the mean age was 68 ± 12 years. Mean intraocular pressure at admission was 53.4 ± 12.4 mmHg, and 9.2% of patients presented only non-ocular complaints, while 9.2% presented mixed complaints (ocular and non-ocular). Most patients (68.1%) with only non-ocular or mixed complaints were triaged to a non-ophthalmologist (p < 0.001). Concerning the triage system, at admission, most patients (66.7%) were labelled yellow (urgent), while 9.2% and none were labelled as orange (very urgent) or red (emergent), respectively. Most patients (83.3%) were directly sent to Ophthalmology (properly triaged), while the remaining were incorrectly assigned to a non-ophthalmologist. Median time until observation by Ophthalmology was 49 minutes in the properly triaged group (min. 15, max. 404), while it was 288 minutes (min. 45, max. 871) in those who were incorrectly triaged (p < 0.001). Likewise, median time until treatment with laser iridotomy was 203 minutes in the properly triaged group (min. 22, max. 1440) and 353 minutes in the incorrectly triaged group (min.112, max. 947) (p < 0.001). Most patients with acute primary angle closure attack were not properly triaged according to the level of the Manchester triage system. There was a significant delay in the diagnosis and treatment of those patients who were first assigned to non-ophthalmologists. There is a need to raise awareness regarding the presenting signs and symptoms of an acute primary angle closure attack in order to avoid preventable vision loss.

To systematically review the characteristics of patients experiencing acute angle closure (AAC) attacks during the COVID-19 outbreak in Beijing. Patients with AAC attacks during the COVID-19 epidemic and those in the same period the following year were recruited. Demographic characteristics, ocular biometry, ocular signs, sequential relationships, and the prognosis of operative management outcome were recorded and compared between the 2 groups. We included 60 eyes of 55 patients with AAC attacks in the COVID-19 group and 34 eyes of 33 patients in the control group. There was a significantly higher incidence of bilateral attacks during the COVID-19 outbreak compared to the control group (9 vs 1, P = .043). Additionally, a higher proportion of AAC attacks were observed in the COVID-19 group (P = .035). The COVID-19 group had a higher mean peak intraocular pressure (53.42 ± 8.87 mm Hg vs 47.86 ± 11.22 mm Hg; P = .007), larger pupil diameter (5.75 ± 1.04 mm vs 4.86 ± 1.26 mm; P < .001), more pigmented keratic precipitates (39 vs 8, P < .001), and segmental atrophy of the iris (32 vs 10, P = .019). Coronavirus infection was simultaneous with or slightly preceded the appearance of AAC attacks. Most patients had an ideal prognosis after comprehensive management. An increased incidence of AAC attacks, more bilateral cases and severe anterior segment inflammation were observed during the COVID-19 outbreak in Beijing. There may be a correlation between the onset of AAC attacks and coronavirus infection, but further research is needed to explore this link.

Factors Associated With Zonular Instability During Cataract Surgery in Eyes With Acute Angle Closure Attack

Objective: To assess the effectiveness of combined phacoemulsification and goniosynechialysis (PE-GSL) of angle closure glaucoma in patients with uncontrolled intraocular pressure (IOP) and persistent peripheral anterior synechiae (PAS) initially presented with acute angle closure attack. Materials and Methods: The present study was a retrospective cohort study of medical records of Thai glaucoma patients comprising 19 eyes of 19 patients (13 females and 6 males) with acute angle closure attacks. All patients were performed with PE-GSL Results: There were statistically significant differences between preoperative and postoperative IOP, PAS, and the number of medications required for IOP control. Postoperative visual acuities were improved. At the final examination for each patient, IOP was 12.15±1.57 mmHg (range 10 to 16). The extent of recurrent PAS was 66.32±40.72° (range 0 to 90), and the number of antiglaucoma medications was 0 (range 0 to 2). IOP was less than 20 mmHg in 16 eyes (80%) without medications. Three eyes were controlled with medications. In the 16 eyes with successful PE-GSL, the mean time between the angle closure attack and surgery was 7.5±5.6 weeks. Conclusion: PE-GSL are effective in decreasing IOP, PAS, and medications, as well as improvement of visual acuity in eyes with uncontrolled IOP and persistent PAS in patients who initially presented with acute angle closure attacks.

Purpose: To report a case of choroidal metastasis as the main presentation in a patient with lung carcinoma. Method: Case report. Results: A 69-year-old woman complained of blurred vision in her right eye for 2 months. The best-corrected visual acuity was counting finger in right eye. Fundoscopy demonstrated a large choroidal mass located inferiotemporally associated with exudative retinal detachment in her right eye. B-scan ultrasound revealed the tumor had a high internal reflectivity. Magnetic resonance imaging of the orbit showed an intraocular mass that was approximately 5 mm in thickness. After enucleation, pathologic study of the enucleated eye demonstrated a choroidal metastasis. Complete systemic survey disclosed that a primary lung adeno-carcinoma with bone and choroidal metastasis count for the ocular lesion. Conclusions: Choroidal metastasis can be the first clinical manifestation of lung adenocarcinoma. Ophthalmologists should be aware of systemic malignancy in choroidal metastasis and initiate a thorough systemic evaluation for early detection of life-threatening malignancies.

To document the effect of a previous acute angle closure attack on the corneal endothelial cell density in chronic angle closure glaucoma (CACG) patients. Consecutive cases of CACG with patent peripheral iridotomy had their central corneal endothelial cell density measured by specular microscopy. The corneal endothelial cell density of those CACG eyes with a previous documented acute angle closure attack were compared with those eyes without such a history, to determine the effect of a previous acute angle closure attack on corneal endothelial cell density. From July 2003 to July 2005, a total of 52 CACG eyes of 52 patients fulfilling the study criteria were recruited. Thirteen eyes (25%) had a previous documented acute angle closure attack, whereas 39 eyes (75%) did not. The mean central corneal endothelial cell density +/-1 standard deviation was 2271.7+/-312.9 (range, 1556 to 2661) cells/mm in those CACG eyes with previous acute angle closure, and 2570.0+/-429.9 (range, 1669 to 3861) cells/mm in those CACG eyes without previous acute angle closure (P < 0.05, Student t test). A previous acute angle closure attack in a CACG eye correlates with a 11.6% reduction in corneal endothelial cell density, compared with a CACG eye without such a history. There were no statistically significant differences between the 2 groups in age, LogMAR visual acuity, intraocular pressure, number of glaucoma eye drops, vertical cup-to-disk ratio, mean deviation or pattern standard deviation in Humphrey automated perimetry (P > 0.05). A previous acute angle closure attack correlates with a significantly reduced corneal endothelial cell density in CACG patients.

Acute Primary Angle Closure Structural Damage

Acute Primary Angle Closure

Aim: To evaluate the biometric difference between eyes with acute angle-closure (AAC) attack, their uninvolved fellow eyes and eyes with chronic angle-closure glaucoma (CACG). Methods: Patients with prior laser iridotomy on both eyes for unilateral AAC attack or CACG were recruited. We compared ocular biometric parameters by A-scan ultrasonography of the acutely affected eyes with those of the uninvolved fellow eyes and with eyes affected by CACG. Results: Thirty-three patients with unilateral AAC attack and 41 patients with CACG were included. The eyes with AAC attack had a significantly shallower anterior chamber depth (ACD), thicker lens, shorter axial length, higher lens/axial length factor and more anteriorly positioned lens than the eyes with CACG. The uninvolved fellow eyes had a significantly shallower ACD, shorter axial length and higher lens/axial length factor compared with the eyes with CACG. Acutely affected eyes had a shallower ACD and more anteriorly positioned lens than did the uninvolved fellow eyes. Conclusion: Eyes with AAC attack had a more crowded anterior segment compared with uninvolved fellow eyes and those affected by CACG. In addition to ACD, relative lens size, represented by the lens/axial length factor, and relative lens position appear to play important roles in the development of AAC attack.
