OCT + 시야검사 결과로 보는 녹내장 초기 신호와 눈 건강 관리법

눈의 건강은 한 번 손상되면 회복이 어렵습니다. 그래서 정기적인 OCT 검사 와 시야검사 는 매우 중요합니다. 이번 글에서는 실제 환자분의 검사 예시를 통해 시신경 손상의 초기 변화와 관리법 을 알기 쉽게 설명드리겠습니다. 🔍 OCT(빛간섭단층촬영) 검사란? OCT 검사는 망막과 시신경의 구조를 단층(층별) 으로 촬영하는 검사입니다. 눈 속 신경층의 두께, 황반 중심부의 형태, 망막 부종 여부 등을 세밀하게 확인할 수 있어 녹내장, 황반변성, 당뇨망막병증 같은 질환의 조기 발견에 매우 유용합니다. 검사 시간: 약 5분 통증: 없음 결과 확인: 바로 가능 disc OCT(오른쪽) disc OCT(왼쪽)   OCT(빛간섭단층촬영) 검사 결과 설명 🔹 1. 검사 개요 OCT 검사는 망막(눈 안쪽의 신경막)과 황반(시력의 중심부)을 단층 촬영 해서, 눈 속 구조의 미세한 변화를 관찰하는 검사입니다. 즉, 망막이 얼마나 두꺼운지 , 부종이나 손상이 있는지 , 황반 중심이 정상인지 를 보는 검사예요. 🩺 오른쪽 눈 (R) 망막 두께(Macular Thickness): 약간 얇아진 부위 가 있습니다. 황반 중심(Fovea): 형태는 전반적으로 유지되어 있지만, 중심부의 미세한 손상 흔적 이 보입니다. 망막층 구조: 일부 내층(Inner layer) 이 얇아져 있으며, 이는 혈류 감소나 시신경 손상 초기 에서 보일 수 있는 소견입니다. 시세포층(Photoreceptor layer): 대체로 보존되어 있지만, 경계가 약간 흐릿한 부분 이 있어, 시야 흐림이나 중심 시력 저하 를 유발할 가능성이 있습니다. ➡️ 정리: 현재 심한 황반변성이나 망막박리 같은 질환은 보이지 않지만, 시신경 또는 황반 중심부의 기능 저하 초기 로 보입니다. 따라서 정기적인 경과 관찰 과 혈류 개선제 또는 안구 순환 개선 약물 복용이 도움이 됩니다. 🩺 왼쪽 눈 (L) 망막 두께: 오른쪽보다 약...

Stye vs. Chalazion: Understanding the Differences, Causes, and Treatments

Introduction

A red, swollen lump on your eyelid can be both uncomfortable and concerning. Many people confuse styes and chalazions, as they appear similar but have different causes and treatments. In this comprehensive guide, we will explore the differences between a stye and a chalazion, their causes, symptoms, treatment options, and preventive measures.


What is a Stye?

A stye (hordeolum) is a painful, red lump that develops at the edge of the eyelid due to a bacterial infection in an oil gland or hair follicle.

Causes of a Stye

Styes are primarily caused by Staphylococcus bacteria, which infect the oil glands near the base of the eyelashes. Common risk factors include:

  • Touching the eyes with dirty hands

  • Poor eyelid hygiene

  • Using old or contaminated eye makeup

  • Wearing contact lenses without proper cleaning

  • Chronic blepharitis (eyelid inflammation)

Symptoms of a Stye

  • Red, swollen lump near the eyelid margin

  • Pain and tenderness in the affected area

  • Pus-filled bump (may develop a white or yellow head)

  • Watery eyes and light sensitivity

  • Crusting around the eyelid

Types of Styes

  1. External Stye – Forms at the base of the eyelash due to an infected hair follicle.

  2. Internal Stye – Develops inside the eyelid due to an infection in the meibomian gland.


What is a Chalazion?

A chalazion is a slow-growing, painless lump that results from a blocked oil gland (meibomian gland) in the eyelid. Unlike styes, chalazions are not caused by bacterial infections.

Causes of a Chalazion

Chalazions develop when an oil gland in the eyelid becomes blocked, leading to inflammation. Common causes include:

  • Poor eyelid hygiene

  • Chronic blepharitis

  • Meibomian gland dysfunction

  • Rosacea and other skin conditions

Symptoms of a Chalazion

  • Firm, painless lump in the eyelid

  • Swelling and redness (especially in early stages)

  • Blurred vision if the lump presses against the eye

  • Mild tenderness (in some cases)

  • Gradual growth over several weeks


Key Differences Between a Stye and a Chalazion

FeatureStye (Hordeolum)Chalazion
CauseBacterial infection (Staphylococcus)Blocked oil gland
Pain LevelPainful and tenderUsually painless
LocationNear the eyelash base or inside the eyelidInside the eyelid
AppearanceRed, swollen lump with possible pusFirm, round lump
Speed of GrowthDevelops quickly (within a few days)Grows gradually (over weeks)
Pus/DischargeMay release pusNo pus or discharge
TreatmentWarm compress, antibiotics (if severe)Warm compress, steroid injection, or surgical removal (if needed)

Treatment for Styes and Chalazions

1. Warm Compress

Applying a warm compress for 10-15 minutes, 3-4 times a day can help both styes and chalazions by softening the blockage and promoting drainage.

2. Good Eyelid Hygiene

  • Wash hands before touching the eyes.

  • Clean eyelids daily with mild baby shampoo or eyelid cleansers.

  • Remove makeup before sleeping.

3. Avoid Squeezing or Popping

Trying to pop a stye or chalazion can spread infection and worsen inflammation. Let it drain naturally.

4. Antibiotics (for Styes Only)

  • If a stye is severe, an eye doctor may prescribe antibiotic eye drops or ointments.

  • Oral antibiotics are rarely needed but may be recommended for recurrent cases.

5. Steroid Injections (for Chalazions)

If a chalazion persists for several weeks and does not respond to warm compresses, a doctor may inject a steroid (corticosteroid) to reduce inflammation.

6. Surgical Drainage

  • Large or persistent chalazions may require a minor surgical procedure to drain the blocked gland.

  • This is typically done under local anesthesia by an ophthalmologist.


Prevention Tips for Styes and Chalazions

  1. Practice Good Eye Hygiene – Wash hands frequently and avoid touching the eyes.

  2. Keep Eyelids Clean – Use warm water and a mild cleanser to remove excess oil and debris.

  3. Replace Makeup Regularly – Discard old mascara, eyeliner, and eyeshadow to prevent bacterial buildup.

  4. Avoid Rubbing Your Eyes – This reduces the risk of transferring bacteria.

  5. Manage Underlying Conditions – Treat blepharitis, rosacea, or meibomian gland dysfunction to prevent blockages.

  6. Use Clean Contact Lenses – Always disinfect lenses properly and avoid wearing them overnight.


When to See a Doctor

  • If the stye or chalazion does not improve after 2 weeks of home treatment

  • Severe pain, excessive swelling, or vision problems develop

  • The lump continues to grow or frequently recurs

  • Signs of an eye infection, such as fever or spreading redness


Conclusion

Styes and chalazions may look similar, but they have distinct causes and treatment methods. Understanding their differences can help you manage symptoms effectively and seek appropriate care. If a stye or chalazion persists despite home treatments, consult an eye specialist for professional evaluation and treatment options.
