Biomedicines 2024; 12:1758. [PMID: 39200222 PMCID: PMC11352094 DOI: 10.3390/biomedicines12081758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 07/22/2024] [Accepted: 07/24/2024] [Indexed: 09/02/2024] Open
Abstract
Uveal melanoma (UM) is the most common intraocular malignancy in adults. Recent advances highlight the role of tumor-derived extracellular vesicles (TEV) and circulating hybrid cells (CHC) in UM tumorigenesis. Bridged with liquid biopsies, a novel technology that has shown incredible performance in detecting cancer cells or products derived from tumors in bodily fluids, it can significantly impact disease management and outcome. The aim of this comprehensive literature review is to provide a summary of current knowledge and ongoing advances in posterior UM pathophysiology, diagnosis, and treatment. The first section of the manuscript discusses the complex and intricate role of TEVs and CHCs. The second part of this review delves into the epidemiology, etiology and risk factors, clinical presentation, and prognosis of UM. Third, current diagnostic methods, ensued by novel diagnostic tools for the early detection of UM, such as liquid biopsies and artificial intelligence-based technologies, are of paramount importance in this review. The fundamental principles, limits, and challenges associated with these diagnostic tools, as well as their potential as a tracker for disease progression, are discussed. Finally, a summary of current treatment modalities is provided, followed by an overview of ongoing preclinical and clinical research studies to provide further insights on potential biomolecular pathway alterations and therapeutic targets for the management of UM. This review is thus an important resource for all healthcare professionals, clinicians, and researchers working in the field of ocular oncology.

MOLECULAR BIOMEDICINE 2024; 5:17. [PMID: 38724687 PMCID: PMC11082128 DOI: 10.1186/s43556-024-00182-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Accepted: 04/08/2024] [Indexed: 05/12/2024] Open
Abstract
Uveal cancer (UM) offers a complex molecular landscape characterized by substantial heterogeneity, both on the genetic and epigenetic levels. This heterogeneity plays a critical position in shaping the behavior and response to therapy for this uncommon ocular malignancy. Targeted treatments with gene-specific therapeutic molecules may prove useful in overcoming radiation resistance, however, the diverse molecular makeups of UM call for a patient-specific approach in therapy procedures. We need to understand the intricate molecular landscape of UM to develop targeted treatments customized to each patient's specific genetic mutations. One of the promising approaches is using liquid biopsies, such as circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA), for detecting and monitoring the disease at the early stages. These non-invasive methods can help us identify the most effective treatment strategies for each patient. Single-cellular is a brand-new analysis platform that gives treasured insights into diagnosis, prognosis, and remedy. The incorporation of this data with known clinical and genomics information will give a better understanding of the complicated molecular mechanisms that UM diseases exploit. In this review, we focused on the heterogeneity and molecular panorama of UM, and to achieve this goal, the authors conducted an exhaustive literature evaluation spanning 1998 to 2023, using keywords like "uveal melanoma, "heterogeneity". "Targeted therapies"," "CTCs," and "single-cellular analysis".

Abstract
BACKGROUND Ciliary body tumor is extremely rare and treatment is challenging. The aim of this study is to present our experience in treating this rare entity, especially large tumors with more than 5 clock hours of involvement, and to evaluate the surgical outcomes and complications of local resection via partial lamellar sclerouvectomy in four cases of ciliary body tumors in China. METHODS Four patients with ciliary body tumors underwent partial lamellar sclerouvectomy between October 2019 and April 2023 in Shanghai General Hospital, China. Tumor features, histopathologic findings, complications, visual acuity, and surgical outcomes were reviewed at a mean follow-up of 20.8 months. RESULTS Four patients with a mean age of 31.8 years were included in this study. The histopathological diagnosis was adenoma of non-pigmented ciliary epithelium (ANPCE), schwannoma, and multiple ciliary body pigment epithelial cysts. The mean largest tumor base diameter was 6.00 mm (range: 2.00-10.00) and the mean tumor thickness was 3.50 mm (range: 2.00-5.00). Preoperative complications included cataract in 3 (75%) eyes, lens dislocation in 2 (50%), and secondary glaucoma in 1 (25%). Temporary ocular hypotonia was observed in one case and no other postoperative complications were observed. At a mean follow-up of 20.8 months, the best corrected visual acuity increased in 3 eyes and was stable in 1 eye. Tumor recurrence was absent in all eyes. All patients were alive at the end of follow-up. CONCLUSIONS Local tumor resection via PLSU is useful in the treatment of ciliary body tumors, including large tumors occupying more than five clock hours of pars plicata. Surgery-related complications were manageable with adequate preoperative assessment and careful operation during surgery.

Abstract
Uveal Melanoma (UM) is a rare disease, yet it is the most common primary intraocular malignancy in adult patients. Despite continuous advancements and research, the risk of metastasis remains high. It is possible to stratify patients according to their risk of metastases using a variety of known risk factors. Even though there is no gold standard for the prognostication of patients with uveal melanoma, it is becoming increasingly clear that combining histo-pathological, patient-related and molecular prognostic markers allows a more accurate prediction of the metastatic risk than by using one parameter. Primary UM in the eye are treated very effectively with eye-sparing radiation-based techniques or enucleation. However, it is not yet possible to prevent or treat metastases with the current therapeutic options. Nonetheless, the efforts to find new therapeutic targets continue and progress is being made, especially in the field of targeted therapy, as exemplified by the anti-gp100 bispecific molecule Tebentafusp. This review delves into the history of uveal melanoma, its incidence, presentation and diagnosis, the known prognostic factors and the treatment options, both for the primary tumour and for metastases. We show that different populations may have different risks for developing UM, and that each country should evaluate their own patients.

Abstract
Purpose The purpose of this study was to investigate the direct impact of the combined angiokinase inhibitor nintedanib as well as the anti-angiogenic agents ranibizumab, bevacizumab, and aflibercept on the primary uveal melanoma (UM) cell line Mel270 and liver metastasis UM cell line OMM2.5. Methods The metabolic activity, viability, and oxidative stress levels were analyzed by the Thiazolyl Blue Tetrazolium Bromide (MTT), LIVE/DEAD, and reactive oxygen species (ROS) assays. Expression of intracellular VEGF-A165 and VEGF receptor-2 was detected by immunofluorescent staining. The secretion of VEGF-A165 into the cell culture supernatants was evaluated by VEGF-A165 ELISA. Results Nintedanib, at a concentration of 1 µg/mL, resulted in a median reduction of metabolic activity (for Mel270 of approximately 38% and for OMM2.5 of 46% compared to the untreated control) without exerting toxicity in either cell line, whereas the other 3 substances did not result in any changes (which also means that none of the 4 substances led to an increased cell death). Moreover, nintedanib (1 µg/mL) induced oxidative stress in the Mel270 by approximately 1.2 to 1.5-fold compared to the untreated control, but not the OMM2.5 cells. Conclusions Nintedanib could suppress the growth of UM cells in a concentration-dependent manner. The metastatic UM cell line OMM2.5 was not sensitive to the pro-oxidant activity of nintedanib. This study was the first to investigate nintedanib in the context of UM. We propose further investigation of this substance to elucidate its effects on this tumor entity with the hope of identifying advantageous therapeutic options for future adjuvant tumor therapies.

Clinical Experience of Stereotactic Radiosurgery at a Linear Accelerator for Intraocular Melanoma Combined with Iridociliary Tumor Resection: A Case Report. Case Rep Ophthalmol 2024; 15:1-7.

Abstract
Introduction The treatment of iridociliary and choroidal melanoma relies on the patient's systemic health, tumor size, location, related features, state of the opposing eye, and personal preferences. The two categories are radiation and surgical techniques. Transpupillary thermotherapy, plaque radiotherapy, charged particle irradiation, local resection, enucleation, orbital exenteration, and experimental nanoparticle therapy are all options for treating choroidal melanoma. Case Presentation The method that entails creating a partial thickness circular, rectangular, or polyhedral scleral flap in the region covering the tumor after removing a portion of the extraocular muscles is the most popular method for local excision in choroidal or choroidal-ciliary body cancers. We discuss our experience treating iridociliary melanoma using block excision and stereotactic irradiation on a linear accelerator with TD 20.0 Gy. Conclusion One of the treatment modalities is the combined treatment approach using stereotactic irradiation and tumor resection, and our results 1 year after therapy are comparable to the rates of local control and anatomic eye preservation to those achieved in studies of comparable uveal melanoma treatment modalities.

Abstract
Uveal melanoma is the most frequent primary intraocular cancer in adulthood and is mostly localised to the choroid. It can be treated using radiation therapy, laser therapy, local resection and enucleation, with the best results achieved by combining these procedures. However, up to half of patients develop metastatic disease. There are no efficacious treatment methods for patients in advanced stage or with metastasis. In recent years, several novel treatment modalities aimed at improving tumour control and reducing adverse events have emerged. This review summarises current clinical treatment methods and new therapeutic perspectives for uveal melanoma.

Abstract
Surgical resection is widely used to treat small tumours located in the iris and the ciliary body, due to the accessibility of these sites. By contrast, surgical removal of choroidal tumours is substantially more challenging, which is why this procedure is performed only at specialised centres. In the present article, we review the literature on surgical resection of choroidal tumours, which can be performed as endoresection (ab interno) or transscleral resection (ab externo). An important aim of this review is to describe and compare the two approaches in terms of visual outcomes, survival rates, and complications. Both approaches are indicated for the removal of large tumours (thickness > 8 mm) with small base diameters. Surgical resection of the tumour allows clinicians to obtain valuable histopathologic and cytogenetic data from the specimen and eliminates the risks associated with radiotherapy. However, both of these surgical approaches are technically challenging procedures involving the risk of severe early and late postoperative complications.

Abstract
OBJECTIVES To investigate the results of partial lamellar sclerouvectomy (PLSU) for anteriorly located uveal tumours. METHODS We reviewed the tumour features, histopathologic findings, complications, visual acuity outcomes, eye preservation, metastasis, and mortality data of 56 cases with uveal tumours who underwent PLSU between February 1999 and February 2019. RESULTS The mean largest tumour base diameters were 5.8 × 3.4 mm and the mean tumour thickness was 3.3 mm. Histopathologically, 30 (53.6%) eyes had malignant melanoma, 13 (23.2%) had nevus, 5 (8.9%) had iris stromal cyst, 4 (7.1%) had melanocytoma, 2 (3.6%) had Fuchs' adenoma, 1 (1.8%) had iris pigment epithelial cyst, and 1 (1.8%) had invasive breast cancer metastasis. The most common postoperative complications included cataract in 21 (37.5%) eyes, vitreous haemorrhage in 15 (26.8%), scleral thinning in 10 (17.9%), and hyphema in 6 (10.7%). At a mean follow-up of 40.4 (range: 10-201) months, tumour recurrence was observed in 2/30 (6.7%) eyes with melanoma and 1/5 (20.0%) eye with iris stromal cyst. Eyes with recurrent melanoma were treated with enucleation. Liver metastasis developed in only 1 (3.3%) melanoma case. All patients were alive at the end of follow-up. CONCLUSIONS PLSU is a successful treatment method for many anteriorly located uveal tumours. In our series, the overall tumour recurrence and globe salvage rates were 5.4% and 96.4% respectively. Among melanoma cases, the metastasis rate was 3.3% and survival rate was 100%.

Clinical Outcomes after Surgical Resection Combined with Brachytherapy for Uveal Melanomas. J Clin Med 2022; 11:jcm11061616. [PMID: 35329942 PMCID: PMC8956023 DOI: 10.3390/jcm11061616] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Revised: 03/10/2022] [Accepted: 03/11/2022] [Indexed: 02/01/2023] Open
Abstract
Currently, brachytherapy is the most commonly used therapeutic approach for uveal melanomas. Surgical resection by means of endoresection or exoresection is an alternative approach. The present report recounts our experience over 15 years in the treatment of uveal melanoma using a combined approach of resection surgery with brachytherapy. This is a single-center observational retrospective cohort study in which we describe clinical outcomes, complications and survival in 35 cases of melanoma of the iris or the ciliary body after a combination of surgery and brachytherapy or brachytherapy alone. Local treatment of the tumor was successful in all cases with surgery and brachytherapy. The most frequent complications were scleromalacia, bullous keratopathy, retinal toxicity, cataracts, hypotonia, and photophobia. There were three cases of recurrence, all of which were found in the group of patients who had received brachytherapy alone, and in one case we had to perform a secondary enucleation due to tumor growth after brachytherapy. At present, only one patient has died during follow-up due to liver metastases six years after the start of treatment. In carefully selected patients, this approach can be effective and safe, as long as a close follow-up is carried out after surgery.

Abstract
Objective To review the current state of radiation therapy for uveal melanoma and compare particle radiation and brachytherapy. Patients and Methods The medical records of 156 patients treated for uveal melanoma between May 30, 2012, and March 16, 2020, were retrospectively reviewed. Treatments consisted of either radioactive iodine 125 implant (RAI) or fractionated proton radiation (proton beam therapy [PBT]). Baseline characteristics were compared using a Wilcoxon rank sum test or χ2 test. Outcomes were compared using Cox proportional hazards regression models or logistic regression models. Results The median length of follow-up after treatment was 2.7 years (range, 0.5 to 9.0 years). Patients who underwent treatment with RAI were older (median age, 67 vs 59 years; P<.001) and had a lower tumor classification (American Joint Commission on Cancer; P=.001) compared with those who underwent PBT. There was no significant difference between RAI and PBT in the outcomes of liver metastases, death, enucleation, tearing, vision loss, retinal detachment, tumor thickness, conjunctivitis, optic neuropathy, iris neovascularization, or neovascular glaucoma (all P>.05). Patients who underwent RAI treatment had significantly higher risk of diplopia (P<.001), cataract progression (P<.001), and maculopathy (P=.03) compared with those who received PBT. Patients who underwent RAI were at higher risk of eyelash loss (P=.006) compared with the PBT group. Conclusion Treatment with PBT and RAI has similar efficacy; however, there are differences in the adverse outcomes associated with these 2 modalities.

Abstract
BACKGROUND Uveal melanoma is a rare intraocular tumour, for which there is currently no national evidence-based guideline in Germany. The aim of this project was to provide a common standard operating procedure (SOP) for the diagnosis, treatment and follow-up care of uveal melanoma, within the network of German leading oncology centres funded by German Cancer Aid. The SOP was created as part of a moderated consensus process. RESULTS AND CONCLUSION In a multistage process, a common SOP was developed for the diagnosis, therapy and follow-up of uveal melanoma, as based on current knowledge of the subject.

Abstract
The aim of intraocular melanoma therapy is to achieve local tumor control, reduce the risk of metastasis development, preserve the eyeball and possibly the visual function of the eye. The choice of therapeutic approach requires a comprehensive view and individual approach to each patient with uveal melanoma. Factors considered include local finding (location, tumor size and shape, tumor activity, central visual acuity, intraocular complications), age and the patients overall physical and psychological condition, as well as the patients wishes. The most widely used method of uveal melanoma treatment is radiotherapy. The effect of radiation is caused by the absorption of ionizing radiation energy, the effect of radiation on the cell is manifested by cell death (depletion), or by a cytogenetic information change (mutation). Brachytherapy uses scleral applicators with radionuclide - ruthenium (Ru-106) applicators dominate in Europe and iodine (I-125) applicators in the USA. In external radiotherapy, the source of ionizing radiation is outside the patients body. Both stereotactic radiosurgery and fractionated stereotactic radiotherapy are used. In the Czech Republic, treatment is carried out using Leksell gamma knife or CyberKnife, while proton therapy dominates in the world. The development of serious radiation complications (radiation retinopathy, neuropathy, neovascular glaucoma, toxic tumor syndrome, etc.) should be considered. Surgical therapy involves a variety of invasive procedures. Iridectomy is performed for iris melanoma. Anteriorly located choroidal melanomas and / or ciliary body melanomas can be resolved by transscleral resection (exoresection). For posterior choroidal melanomas, a combination of external tumor irradiation with pars plana vitrectomy is used. Enucleation is a method of choice in advanced tumors that cannot be effectively irradiated. Orbital exenteration is indicated in advanced tumors with extrabulbar spread or in relapsed tumor after previous enucleation.

Abstract
Abstract
The purpose of the study was to analyze single fraction Gamma Knife stereotactic radiosurgery (SRS) for uveal melanoma (UM). In the treatment of UMs, the dose distribution exhibited by an irregular eye surface has more calculation uncertainty. A tissue-equivalent bolus was placed on the left eye surface of a human head-shaped phantom. It was assumed that the treated eye is fixed using retrobulbar anesthesia and suture on extraocular muscles for phantom study. Leksell stereotactic frame was fixed around phantom’s head and the stereotactic computed tomography (CT) was performed. Two sets of scans were acquired (a) without bolus and (b) with a bolus of 1.0 cm thickness. These scans were transferred into a treatment planning system (TPS). The skull contouring was performed using stereotactic CT images. The target, visual pathways, and eye lens were delineated in stereotactic CT space created on TPS. A clinical relevant plan was designed on the CT study set “a” to deliver a radiation dose of 30Gy at tumor margin. The plan superimposed over CT study set “b” and compiled for convincing treatment strategy. The tumor coverage was 95% at 50% prescription isodose line. The conformity index, selectivity and the gradient index were 1.27, 0.80 and 3.28 respectively. The left optic nerve and eye lens received a maximum dose of 11.1 Gy and 11.0 Gy respectively. The treatment plan overlay showed similar planning indices and critical organ doses. The plan comparison showed: an irradiated volume received the radiation dose > 15 Gy varies < 1.0% whereas the volume received < 15 Gy were larger (> 1.0%) in the study set “b”. The distant lateral points from the target volume which describe the phantom’s eyelid showed a radiation dose of 3.2 Gy - 2.5 Gy. The doses to these points were misled and ignored in the CT study set “a”. The eye bolus provides better dosimetric information in the estimation of low dose areas which is commonly misled on TPS in SRS planning for UMs.

Abstract
Local treatment of choroidal melanoma (CM) attracts the attention of many ophthalmology specialists, especially in recent years as the capabilities to target irradiation at small objects and possibilities of surgical interventions on the eyeball have expanded. The article discusses the medical indications for local treatment of CM. Review of literature of the last 16 years and author's own observations on CM patients who underwent almost all kinds of conventional methods of local treatment allowed thorough analysis of indications and counter-indications for their usage. Among the authors who favor local destruction and removal of large CM, the main indication is the possibility to preserve vision and anatomical structures of the eye. This led to unreasonably wide spread of local destruction (removal) of large CM, primarily the endovitreal resection method. However, such metastasis risk factors as CM size and its localization are being overlooked. Literature analysis and author's own observations helped validate the unsafety of the local treatment of large CM. The article features long-term results of contact and distant radiation therapy, and presents CM metrics for best therapeutic effect.

Abstract
Purpose To review long time treatment results in patients with small or medium sized choroidal melanoma who underwent surgical tumor endoresection as a primary treatment when plaque radiotherapy was unable and patients declined enucleation. Materials and methods Patients were evaluated for best corrected visual acuity (BCVA), and underwent biomicroscopy, indirect ophthalmoscopy, retinography and ultrasound as well as the usual systemic workup. Study inclusion required the absence of scleral invasion or metastasis and an anterior margin not exceeding the pars plana or the ciliary body. Surgery consisted of a clear lens phacoemulsification with a PC-IOL, and a 23-gauge pars plana vitrectomy with anterior vitreous shave, lesional choroidal endodiathermy, followed by 23-gauge probe tumor endoresection and continuous endolaser. Patients were followed at post-operative 1 day, 1 week, 1, 3, and 6 months and then every 6 months with a complete ophthalmological exam including ultrasound biomicroscopy and systemic follow-up at 3, 6 and every 6 months thereafter. Results Fourteen patients with choroidal melanoma were included the study. Pre-operative BCVA ranged from 20/20 to hand motion (HM): 20/20 (n = 2); 20/60 (n = 1); and HM (n = 10). Pathological analysis confirmed the diagnosis of uveal melanoma in all cases. Mean follow-up was 54.5 months (45–66 months) with a final BCVA ranging from 20/60 to HM: 20/60 (n = 1); 20/60 to 20/200 (n = 10); and HM (n = 2). The eye retention rate in our study was 100%. No intraocular recurrence was observed. One patient died 12 months after surgery from metastatic disease. Conclusion Endoresection appears to be an acceptable alternative to enucleation for the treatment of posteriorly-localized uveal melanoma, with excellent local control and eye salvage rates.

Abstract
AIMS To describe results after neoadjuvant proton beam irradiation followed by transscleral resection of large uveal melanoma. METHODS Retrospective interventional case series, including 106 consecutive patients. Local tumour control, enucleation and metastasis development were assessed with survival curves. Predictors of local recurrence and metastasis were investigated with log-rank testing. RESULTS Mean follow-up was 3.2 years. Local recurrence occurred in five cases with an estimated risk of 4.2% and 10.4% at 3 and 5 years after treatment, respectively. Enucleation was performed in 10 cases with an estimated risk of 9.2% and 18.4% at 3 and 5 years, respectively. Significant risk factors for local recurrence were not evident. Metastasis was estimated to occur in 28.4% at 3 years and 40.3% at 5 years, correlating with patient's age only (p=0.01). Seventy four patients (69.8%) underwent vitreoretinal surgery for complications after tumour resection. Median visual acuity (VA) was 20/50 at diagnosis and 20/400 in the third year after treatment. VA preservation of 20/200 or better was achieved in 33 patients (31.1%). CONCLUSION Neoadjuvant proton beam irradiation may help to prevent local recurrence after transscleral resection. Additional vitreoretinal surgery was frequently needed in the presented series. The majority of patients avoided enucleation and functional blindness.

Intravitreal triamcinolone versus intravitreal bevacizumab in the treatment of exudative retinal detachment secondary to posterior uveal melanoma. Am J Ophthalmol 2013; 155:127-133.e2. [PMID: 22995029 DOI: 10.1016/j.ajo.2012.06.026] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2012] [Revised: 06/20/2012] [Accepted: 06/20/2012] [Indexed: 12/24/2022]
Abstract
PURPOSE To evaluate the efficacy and safety of prompt intravitreal triamcinolone acetonide injection (4 mg/0.1 mL) vs intravitreal bevacizumab injection (1.25 mg/0.05 mL) compared with observation in the management of extensive exudative retinal detachment secondary to posterior uveal melanoma. DESIGN Retrospective, nonrandomized, interventional case series. METHODS setting: Institutional. patients: Ninety-six patients affected by posterior uveal melanoma with large exudative retinal detachment (>10 mm in largest basal diameter) were included. intervention: Patients received intravitreal triamcinolone acetonide (32 eyes) or intravitreal bevacizumab (32 eyes) at plaque removal. Thirty-two patients served as controls (observation group). All groups were matched for age, sex, initial tumor thickness and largest basal diameter, largest exudative retinal detachment basal diameter, tumor location, and Bruch membrane rupture. Patients underwent monthly follow-up examinations in the first 6 months and every 3 months thereafter. Follow-up was longer than 24 months. main outcome measure: Exudative retinal detachment resolution (B-scan ultrasonography), steroid-induced cataract, steroid-induced increased IOP. RESULTS Follow-up was 37 ± 7 months. Marked exudative retinal detachment regression was documented in 22 (69%) intravitreal triamcinolone acetonide-treated vs 11 (34%) intravitreal bevacizumab-treated and 9 (28%) untreated eyes (P = .0007 and P = .0001, respectively). No statistical significance was found between intravitreal bevacizumab group vs observation group (P = .45) Steroid-induced cataract was observed in 4 intravitreal triamcinolone acetonide-treated patients (12%). Neither steroid-induced increased IOP nor other short- or long-term side effects were documented. CONCLUSION Intraoperative intravitreal triamcinolone acetonide injection induces earlier and marked exudative retinal detachment resolution after brachytherapy of posterior uveal melanoma. Risk and benefit should be balanced vs steroid-induced cataract.
