Abstract Background: Spherophakia is a rare condition and compared to its occurrence with familial and systemic disorders, isolated spherophakia is even more uncommon. This rare case of isolated spherophakia will raise the alertness of physicians when dealing with a high myopia patient with shallow anterior chamber and relatively normal fundus. Case presentation: We report a case of a 17-year-old male who experienced painless decrease of vision in both eyes (OU) for 11 years, with progression of visual impairment and occasional ocular pain for one year. Examination revealed high myopia, increased intraocular pressures (IOP, 28 mmHg in the right eye (OD) and 33 mmHg in the left (OS)), shallow central anterior chambers, lenses of a spherical shape with superior subluxation, occludable angles without peripheral anterior synechiae, and healthy optic discs OU. A diagnosis of bilateral isolated spherophakia, lens subluxation, high myopia and secondary angle closure (AC) was made. Pars plana lensectomy with anterior vitrectomy and scleral suturing of an intraocular lens was performed. On postoperative follow-up at 19 days OD and 63 days OS, the visual acuity was 6/6 and the IOP was normal without any medication OU. Conclusions: A presentation with high myopia, shallow anterior chamber with a normal retina should alert the clinician to the possibility of spherophakia, as compared to high myopia caused by elongated axial length. Surgery should be considered in cases of spherophakia with AC where the IOP cannot be controlled by noninvasive means.

Secondary glaucoma may develop after vitreoretinal surgery as it is a known risk factor for its development. When the risk factors are more than one, for instance along with neovascular glaucoma (NVG), the secondary glaucoma may become recalcitrant and very difficult to manage. Surgical intervention is often warranted to control intraocular pressure (IOP) and prevent progressive glaucomatous damage in patients with refractory glaucoma, and glaucoma drainage implant may be preferred as the primary choice. We describe a patient who develop secondary glaucoma after vitrectomy and silicone oil (SO) injection due to unresolved vitreous hemorrhage in proliferative diabetic retinopathy (PDR) and subsequent NVG. Baerveldt glaucoma implant (BGI) was carried out and placed in the superotemporal quadrant with longer anterior chamber tube placement to prevent escape of SO through the tube. Qualified success was achieved with additional one fixed-drug combination (FDC). However, 3 years later, the tube was blocked by the iris tissue at the inferior edge of the pupil. Tube trimming was performed efficiently using a simple technique. The distal end of the tube was pulled out of the anterior chamber through a paracentesis just next to the tube entrance and trimmed to the appropriate length. More than a year after the surgery, IOP was still well controlled with the same FDC. Unfortunately, the visual acuity could not be recovered due to advanced PDR.

Cause Of Failure

Records of 48 dogs (57 eyes) that underwent intracapsular lens extraction (ICLE) of displaced lenses were reviewed. Preoperatively, 73% (19/26 eyes) of eyes with anterior luxations had secondary glaucoma compared to 43% (10/23 eyes) with subluxations and 38% (3/8 eyes) with posterior luxations. Forty-one of 57 eyes (72%) had vision and intraocular pressure (IOP) less than 30 mm Hg four to six weeks after surgery. This percentage declined to 61% (22/36 eyes) in three months and 53% (8/15 eyes) in 12 months. Eyes with glaucoma before ICLE had a lower success rate (66%) than eyes without (82%). Since secondary glaucoma was the most common cause of failure, this study suggests that removal of a subluxated lens or a posteriorly luxated lens should be recommended before the lens moves into the anterior chamber.

Ciliary body medulloepitheliomas in childhood often masquerade other intraocular conditions due to its insidious nature as well as its secondary effects on proximal intraocular tissues in the anterior chamber. We report a case where a ciliary body medulloepithelioma in a two-year-old boy presents with chronic uveitis, cataract, and an uncontrolled secondary glaucoma after an innocuous blunt ocular trauma. The diagnosis was only made after the occurrence of a ciliary body mass. We discuss the clinical features of ciliary body medulloepitheliomas, the implications of a delayed diagnosis and treatment as well as the concern of periorbital tumor seeding with the use of an aqueous shunt implant in this case.

Abstract BackgroundTo compare clinical characteristics of lens subluxation between eyes with or without acute angle closure (AAC).MethodsThis is a retrospective and case control study. Thirty-four cases with lens subluxation were recruited from 2015 to 2017. Patients with acute angle closure were assigned to the AAC group (n=17 eyes) and those without AAC were in the non-AAC group (n=17 eyes). Quantitative anterior segment was evaluated by ultrasound biomicroscopy (UBM). Axial length (AL) was measured with IOL master. All patients underwent lens extraction surgery and were followed up for 6 months. ResultsThe history of blunt trauma was accounted for 11 (64.7%) cases in the AAC group and 14 (82.3%) cases in the non-AAC group. Nine (52.9%) patients in the AAC group had LPI or SPI treatment history, and high intraocular pressure was recurred. The UBM analysis showed that the average central ACD of affected eyes in the AAC group was 1.75 mm, which was significantly shallower than the fellow eyes (2.39 mm, P < 0.05) or both eyes in the non-AAC group (affected eye 3.24mm vs fellow eye 3.81mm). Lens vault and AOD500 also showed a remarkable difference between affected eye than fellow eye (P < 0.001) in the AAC group. The both eyes in the AAC group presented a shorter AL and shallower anterior chamber, comparing with those in the non-AAC group. Besides, the affected eyes in the AAC group presented significantly higher LV. ConclusionsThe crowded anterior chamber structure and shorter AL might be an anatomic basis for the eye with lens subluxation induced AAC. Quantitative evaluation of these ocular structures to identify zonular compromise, increased LV and shorter AL are valuable for the diagnosis of lens subluxation induced AAC.

Abstract Background : To compare the anterior biometricsof eyes with secondary acute angle closure induced by occult lens subluxation (ASAC-LS), which were misdiagnosed at the first visit withacute primary angle closure (APAC), chronic primary angle closure glaucoma (CPACG), or cataracts. Methods: This retrospective case series ncluded 17 eyes with angle closure due to occult LS which were misdiagnosed with APAC at the first visit, 56 APACeyes, 54 CPACGeyes, and 56 cataracteyes. The axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), aqueous depth (AD), and lens thickness (LT) were recorded. The lens position (LP), relative lens position (RLP), and corrected lens position (CLP) were calculated. Quantitative data were subject to a one-way analysis of variance and correlation analysis. Categorical data were analysed using the chi-squared test. Receiver operating characteristic (ROC) curves were plotted to obtain a suitable cut-off value for ocular biometrics. Results: The ASAC-LSpatients had a longer ocular AL than the APACand CPACGpatients. The CCTinthe ASAC-LS patientsdid not significantly differ from that in the APAC patientsbut did significantly differ from that of the CPACG and cataract patients.The APAC patientshad the smallest ACD, while the ASAC-LS patientshad the smallest AD. The ASAC-LS patientshad the thickest lenses. According to the ROC curve analysis, the RLP, ACD, AD, CLP, and LP hada high power of discrimination. Conclusions: This study revealed that ASAC-LS patients had a shallower AD and thicker CCT compared to APAC, CPACG, and cataract patients. Biometric parameters ACD, ADwere characteristic of lens subluxation according to our data. The calculated parameters RLP,CLP, LP can be helpful in the differential diagnosis between ASAC-LSand APAC, CPACG, Cataract. Trial registration: NCT03752710, retrospectively registered.

Purpose: The purpose of this study was to describe and summarize the clinical features of congenital fibrovascular pupillary membrane-induced secondary glaucoma (CFPMSG).Design: Cross-sectional case series.Methods: Eyes of 32 patients with CFPMSG were enrolled. Demographic data, including gender, laterality, age at presentation, and age at onset of glaucoma were collected. Patients underwent comprehensive ophthalmic examinations and ultrasound biomicroscopy (UBM). CFPMSG eyes were classified into three groups based on UBM findings and intergroup analysis was performed using ANOVA.Results: The average age at presentation was 2.4 ± 4.6 months (mean ± SD) and at glaucoma onset was 3.8 ± 4.5 months. Compared to normal fellow eyes, all affected eyes had increased intraocular pressure (IOP), axial length, corneal diameter, and central corneal thickness, and decreased anterior chamber depth (ACD) (all P ≤ 0.001). Twenty-two affected eyes (68.8%) had evidence of glaucomatous optic neuropathy. Based on iris configuration on UBM, eyes were classified as 53% type I (“U” shape), 34% type II (“Y” shape), and 13% type III (no anterior chamber). IOP in types II (33.8 ± 5.9 mmHg) and III (35.2 ± 5.9 mmHg) was significantly higher than in type I eyes (26.5 ± 5.1 mmHg). The ACD was shallower in type II compared to type I (P = 0.045).Conclusion: Congenital fibrovascular pupillary membrane-induced secondary glaucoma is characterized by ocular hypertension, corneal enlargement and edema, axial length elongation, and glaucomatous optic neuropathy. Glaucoma in this condition is secondary to pupillary block and angle-closure. UBM provides important information for the diagnosis and classification of CFPMSG. This novel classification system demonstrated varying levels of severity and may guide on management of this disease.
