Understanding Anisocoria: Should I Be Worried About My Uneven Pupils?

3/19/2025, 7:50:18 PMMale25-34

I’m a 190-pound individual standing at 5'11" and currently under watch for a partially torn retina in my right eye, as noted by my doctor. For sleep, I'm taking between 50 to 75 mg of trazodone each night. Over the past year, I've observed a subtle difference in the sizes of my pupils; specifically, my left pupil appears larger than my right. I cannot recall if this has always been the case or if it is a recent development, and previous photos from years gone by do not clarify this for me. While I don’t believe there has been any significant change, my recent online searches have led to anxiety about the potential for serious health issues. I undergo an annual eye examination to renew my glasses and contact lens prescription, and my eye specialist has not expressed any concerns thus far. Interestingly, both pupils seem to react normally to light—constricting in brighter conditions and dilating in the dark. However, I have noted that my right eye tends to be notably drier than the left, particularly upon waking, late in the evening, or after using THCA. This dryness has persisted for the last couple of years. Should this pupil difference be a cause for concern?

It's understandable to feel anxious about changes in your body, including the size of your pupils. Based on your description, the difference in pupil size, known as anisocoria, can be normal for some individuals, especially if you have been previously evaluated by an eye specialist without any concerns raised. Here are some key points to consider:

Explanation

  1. Normal Variance: It's not uncommon for people to have slightly different sized pupils, and if both pupils react correctly to light changes, it usually indicates normal function. Changes over time can occur due to various reasons, such as lighting or other benign factors.

  2. Dryness in the Right Eye: The dryness in your right eye, particularly if it is noticeable upon waking and has been present for a couple of years, may contribute to visual symptoms but is less likely to be related to the anisocoria.

  3. Monitoring: While your annual eye exams have been normal, it is good to remain observant of any significant changes in your eyes or vision.

Next Steps

  1. Continue Monitoring: Keep an eye out for any new symptoms, such as changes in vision, increased dryness, or discomfort in either eye. Document these to discuss in your next eye examination.

  2. Hydration and Eye Care: To help with eye dryness, consider using lubricating eye drops, especially before bed and upon waking. This can provide some relief and help maintain eye comfort.

  3. Follow-Up with Your Eye Specialist: While there might be no immediate concern, don’t hesitate to bring up the anisocoria and dryness in your next appointment, especially since you are under observation for a retinal condition. This will ensure a thorough understanding of your symptoms.

  4. Manage Anxiety: If researching your symptoms online increases your anxiety, consider limiting this and relying on professional evaluations. Keeping communication open with your doctor can help relieve worry.

It's great that you are proactive about your eye health, and continuing your regular examinations will help ensure your eyes remain healthy. If you notice any significant changes, reach out to your healthcare provider for further guidance.

17-Year-Old Female Experiencing Chronic Acne Scarring on Back and Arms Despite Prescription Remedies

Age: 17 Gender: Female Country of residence: United Kingdom Skin type: Dark / Black Medical background: No significant health issues Medications: Previously utilized azelaic acid and benzoyl peroxide Timeframe: Many months to years following acne resolution Greetings, I am a 17-year-old girl dealing with long-lasting scars on my back and upper arms from acne, which have not improved even after following prescribed treatments. In the past, I experienced acne primarily on my upper back, shoulders, and arms. While the active breakouts have largely ceased, I am left with noticeable dark spots and irregular skin texture. The scars I have include: • Dark brown hyperpigmentation • Certain areas appear slightly sunken • Uneven or coarse surface • No raised or keloid scars present My GP prescribed azelaic acid and benzoyl peroxide, which I applied regularly. Unfortunately, the azelaic acid did not significantly lighten the scars and seemed inadequate for the pigmentation level. Although benzoyl peroxide was effective against my active acne, it did not enhance the appearance of the scarring. The marks have been present for a considerable time and are quite stark against my skin tone. I do my best to avoid picking at my skin and maintain proper hygiene, yet the scars aren’t diminishing on their own, which is negatively impacting my self-esteem—especially when I wear sleeveless or backless outfits. Currently, I'm exploring the possibility of using retinoids like adapalene or tretinoin. However, I’m uncertain if these would be suitable or effective for treating scarring on my back and arms, particularly with my darker skin type. I would like guidance on the following questions: • Does this seem to be primarily post-inflammatory hyperpigmentation, atrophic acne scars, or possibly a combination of both? • Is azelaic acid effective for this type of scarring, or are more potent treatments generally required? • Are topical retinoids such as adapalene or tretinoin advisable for this sort of scarring? • What treatments are typically recommended for acne scars on the back and arms in individuals with darker skin tones? • Should I insist on a referral to a dermatologist, or is it better to attempt specific topical therapies first? Any insights or recommendations you could offer would be greatly appreciated.

Persistent Itching and Burning Around Neck and Scalp - Should I Keep Using Cephalexin?

Greetings, I’m a 35-year-old female. I recently developed a rash that began on the back of my neck and subsequently spread to my ears. After consulting with my physician, I was prescribed ketoconazole shampoo to address a suspected fungal rash. Despite using it diligently for four days, the condition actually aggravated, affecting my ears, the back of my neck, and my scalp more significantly. Seeking further assistance, I visited an urgent care facility where the medical staff suggested that I might be experiencing bacterial folliculitis. As a result, they prescribed cephalexin, which I am to take at a dosage of 500mg three times daily for a week. I took my first dose yesterday, yet the intense itching and burning sensations persist without improvement. Is it advisable for me to continue the medication? How long does it typically take to see improvement? Is it common to experience these symptoms alongside bacterial folliculitis? I appreciate your time and any guidance you can provide on this matter!

Concerns About Hearing Loss After Extended Earphone Use

For the past two and a half years, I have primarily relied on in-ear earphones, with the right one typically experiencing less usage—mostly for short videos or brief instances. Recently, during a singing session, I noticed something unusual. I covered one ear to monitor my pitch, and I was surprised to find that my hearing felt unclear and somewhat muffled. This was an experience I hadn’t recognized before. After conducting a few tests by alternately covering each ear, I discovered that my left ear can hear clearly and accurately, while my right ear perceives sounds as muffled, as if there’s a barrier in front of the speaker. I’m seeking advice as a 17-year-old student from Pune, India, with financial constraints that prevent me from adding stress to my parents. I’m deeply concerned whether this issue could be permanent, and if there’s any possibility of recovery. Although I can still hear sounds from my right ear when they are very close, I am unsure of the next steps. I have made the decision to discontinue using earphones starting today, but I’m wondering what additional measures I should take. Would it be advisable to pursue an audiometry test or consult an audiologist for a professional evaluation?

Dealing with Possible Epididymitis

A male, aged 40, standing at 5'9" and weighing 10.5 stone, presents a health concern. He has a history of smoking but refrains from alcohol consumption. For several years, I've grappled with a weakened bladder. However, over the last year or two, I've been experiencing intense discomfort in my right testicle. Initially, I thought I discerned a lump, prompting me to reach out to a physician. Unfortunately, the advice I received was limited; the doctor recommended an STI screening without conducting any examinations. I complied with the test, which returned negative results. Although the pain subsided briefly, it has now returned with greater intensity. I have undergone blood tests focusing on kidney, bladder, and prostate functions, all of which yielded normal results. Now, the medical team is leaning towards a diagnosis of epididymitis. The pain is excruciating and difficult to endure. I’ve scheduled an appointment for a prostate and testicular examination, which may lead to an ultrasound scan or possibly a urethral procedure to eliminate any serious underlying issues. The thought of the forthcoming examination fills me with anxiety, as I'm certain it will be painful. I'm curious if anyone has experienced epididymitis and what outcomes you faced, including any surgical interventions that may have been necessary.

Concerns Regarding Neck Pain After Lifting Incident

I’m a 27-year-old man, standing at 174 cm and weighing 63 kg, residing in Australia. Earlier today, I attempted to lift a heavy case using only one hand. Unfortunately, I didn't realize it was unlatched, and when it opened unexpectedly, I felt significant stress in my lower neck and upper shoulder area. Approximately four hours later, I began to experience a pulsating discomfort on the left side of my neck, extending from beneath my ear down towards my collarbone. I have a medical background of neurological issues related to my vision, along with episodes of facial drooping that are currently under investigation. After the initial neck discomfort (which subsided quickly), I noticed a resurgence of blurriness in my vision. Could this incident have caused an injury to my neck that might be aggravating my neurological symptoms? Is there a chance that this situation could be a vascular emergency?
