Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye.[1] The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye. A variety of conditions can result in blood leaking into the vitreous humor, which can cause impaired vision, floaters, and photopsia.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

2. What Literature says:
• Acute PVD is typically accompanied by floaters (myodesopias or
entopsias) or light flashes (photopsias)
• Significant variability in the literature regarding what the presence or
absence of these symptoms implies
• studies have variably reported that photopsia symptoms are
• 1. Predictive either of a complicated PVD, nonpredictive, or protective
• The risk of RT or RRD occurring with PVD in published reports ranges
widely from 15.0% to 27.1%
3. Current concept
• Acute posterior vitreous detachment (PVD) is a critical lifetime
event that may be associated with the development of a retinal
tear (RT) or rhegmatogenous retinal detachment (RRD), which
may in turn result in permanent vision loss if not identified and
treated promptly.
4. What is the problem with current thinking?
• Prior studies evaluating acute PVD have been
typically performed in retinal specialty practices and
likely suffer from referral bias for more significant
PVD-related events
5. The Question?
• What are the risk factors for retinal tear (RT) or
rhegmatogenous retinal detachment (RRD) associated with
acute, symptomatic posterior vitreous detachment (PVD) in
a comprehensive eye care setting
6. Main Issue
• By not referring to a retina specialist, is the comprehensive
ophthalmologist correct ?
• Especially the chances of missing “Presence of RT or RRD at initial
presentation or within 1 year thereafter”.
7. Reference
• Complications of Acute Posterior Vitreous Detachment.
VOLUME 129, ISSUE 1, P67-72, JANUARY 01, 2022.
• Michael I. Seider, MDCarol Conell, PhD,Ronald B. Melles, MD
8. Rate of RT and RRD associated with acute PVD to be lower than rates
previously reported by retina subspecialty practices.
Several patient features strongly predicted the presence of initial and late
complications of acute PVD

Ophthalmology Volume 129, Number 1, January 2022
9. “How likely is a patient to have a
complicated PVD based
on features that can be determined by a
comprehensive ophthalmologist”
10. Role of comprehensive ophthalmologist:
• Understand
• Risk of RT/RRD at presentation and within 1 year
• Evaluation of rates and risk factors
• Relate between refraction and risk of RT/RRD
12. Population distribution of 8305 patients presenting with acute symptomatic posterior
vitreous detachment (PVD). Women made up 61.2% of the cohort and presented at a
slightly earlier age than men (63.1 vs. 64.7 years, respectively).
13. Risk factors: History & Symptoms
• Blurred vision
• Age < 60 years
• Prior cataract surgery
• Prior photorefractive surgery
• Symptoms < 1 week duration
• Family history of RD
• Floaters
• Flashes
15. • Initial and delayed rates of acute posterior vitreous detachment (PVD) complicated by retinal tear
(RT) or retinal detachment (RD)
• ∗High-risk factors for delayed events included any vitreous hemorrhage, lattice degeneration, or
history of RT or RD in the fellow eye
17. The median interval until a late event was 22 days after initial presentation
93 of the late complications (70.0%) occurred within 6 weeks.
Sixty of the late events (45.1%) were detected at a scheduled follow-up appointment
19. Refractive Error
• High myopia (-3.00D -6.0 D ) risk factor for complicated PV
• Independent of patient age
• Relatively linear relationship
• Between
• The age at presentation of PVD and refractive error
• Myopic patients presenting at a younger age
• Hyperopes at a later age, compared with emmetropes
20. Factors predictive of Late events
• More likely to occur in patients who initially presented with
• 1. Vitreous hemorrhage
• 2. Lattice degeneration
• 3. History of RT or RD in the fellow eye
• 4. Occur at a median of 22 days after presentation
• 5. Follow up closely sooner than interval of 6 weeks
21. Salient Points
• Incidence of RT during acute PVD in comprehensive ophthalmology is
substantially lower than that reported in series from retina subspecialty clinics
• Specific risk factors that can assist in predicting which patients are at highest
risk of complicated PVD both at triage and the time of initial examination
22. Predictive Factors of Late events
• Vitreous hemorrhage
• Lattice degeneration,
• History of RT or RRD in the fellow eye
• Patients with any of these key characteristics should be observed closely
23. Refractive error
• Close relationship among refractive error, patient age at PVD, and
risk of complicated PVD, with myopic eyes not only presenting at a
younger age but also having an independently greater risk of
associated RT or RRD
